Now is the Time to Plant Garlic

Now is the perfect time to plant garlic. Growing your own garlic is easy and the cloves are tastier than what you purchase in a grocery store. Typically, garlic is planted in October in the Washington DC metro area but I have planted as late as Thanksgiving Day.  You may find “seed” stock (the garlic you buy to plant, not the garlic you buy in a grocery store to eat) at independent garden centers, farmers markets, online seed companies, or specialty garlic companies.

Selecting

There are about 200 garlic names so it may be hard to choose. In this area, we can grow both “softneck” and “hardneck” types. The “neck” is the woody central area of the bulb where the flowering stalk or scape emerges the following spring. Softnecks do not produce the scape while hardnecks produce the scape, which some people like to cut and cook even though this would result in a smaller bulb. Because softnecks do not have this woody stem, they are easy to braid for storage. Softnecks mature earlier and have a longer storage life than hardnecks. Softnecks produce large bulbs with the highest number of cloves in various size. These are not easy to peel when you want to use them in the kitchen but eventually, as months pass, they become easier. Hardnecks have less number of cloves but larger and of uniform size, arranged in a single layer around the stalk, and are easy to peel.

The ease of peeling is related to storage. If the clove is easy to peel it is because the peeling is not on tightly hence air can enter and degrade the clove faster. If it is hard to peel, it is because the peeling or wrapper is on so tightly that air cannot enter and cause the clove to dry out. However, as months pass, moisture is lost, the wrapper loosens a little, and the cloves become easier to peel.

Within softnecks (Allium sativum spp. sativum), there are the artichokes (three to five overlapping layers of cloves in various sizes that create a bumpy appearance) and the silverskins with smooth white scales, tightly wrapped cloves, and uniform bulb sizes (most popular for braiding). These store for 8 months.

Within the hardnecks (Allium sativum spp. ophioscorodon) there are rocambole (large, easy to peel cloves but last 4 months), porcelain (largest but few cloves, longest shelf life of the hardnecks), and purple stripe (bright purple streaks and blotches). These store for 4 months.

After selecting if you want a hardneck or softneck, determine your preference for heat and flavor. It may be helpful to read catalog descriptions such as “sweet and mild flavor when cooked,” “white hot” garlic, “high sugar content, good for roasting,” “rich, sweet and caramel-like when roasted,” or “pleasant flavor with a mild spicy zing.”

Planting

Regardless of the type, all garlic is planted, harvested, and cured the same way. Garlic needs rich, well-drained soil. You may have to amend clay soil with organic matter or compost. Garlic can be grown in a garden bed, raised bed, or container as long as the depth is at least 8 inches, preferably 12 inches. Large fabric containers or whisky barrels are possibilities.

Usually the bulb is harvested in June or July when the rest of the garden is in full swing so think of what will replace that gap in the garden. For example, in the fall, you can insert cloves along the perimeter of a large container. In the summer, you can either harvest the garlic and plant summer annuals or you can plant annuals in the late spring and still pull the garlic in the summer and not disrupt the annuals.

Because the plants are tall and narrow, you can fit them in a row in front of your flower bed or in front of shrubs and harvesting should not create an unsightly gap. Many gardeners grow garlic with their rose bushes. It is said that garlic helps keep roses pest and disease free and they do not compete or crowd out roses.

Garlic is a heavy feeder. Depending on where you will plant you may want to amend with compost or manure first in the fall. In the spring, apply nitrogen via bloodmeal, compost tea, or cottonseed meal in April and May.

Garlic also needs full sun. Our rainfall should be sufficient but know that dry soil will make smaller bulbs and do not water 2 weeks prior to harvesting. The area should be kept weed free. Some gardeners mulch to prevent weeds and to prevent frost heaving.

To plant, gently separate the cloves and examine each to make sure it is healthy. Don’t peel each clove but if one is discolored or mushy, throw it away. Plant only healthy cloves, bottom down, pointed end up, about 2 inches deep. Space about 6 inches apart. Large cloves will create large bulbs. The clove will start to grow in the fall and you should see foliage in the fall that will remain during the winter. In the spring, the foliage will continue to grow (which you will be feeding with fertilizer).

Harvesting

If you planted hardnecks, you will see the scapes rise and curl in late spring. Many gardeners cut and eat scapes but this will result in smaller garlic bulbs. If you want larger bulbs, cut the scapes off when they first emerge. Softnecks do not produce scapes.

Harvest the bulbs when half of the leaves have turned yellow or brown and half are still green. For hardnecks this is usually 9 months after planting so will be in June or July. For softnecks, this is earlier, because they grow faster. Harvest on a dry, sunny day. Gently loosen the area surrounding the bulbs with a trowel if in a container or a gardening fork if in a bed and use your hands to bring out the bulbs. The bulbs should not get pierced or damaged.

Curing

Although bulbs can be eaten “fresh” from the ground, the best flavor is obtained from cured bulbs. Curing is the partial drying process to remove the water content from the bulbs so they do not rot or mold in storage. By removing as much moisture as possible, the bulb can remain in its state for a long period of time so you can use the cloves whenever you need them in the kitchen.

To cure, place the garlic bulbs in a shaded, warm, dry area with good air circulation. Do not leave them out in direct sunlight and don’t wash with a hose. Some people like to spread them out on a tray or large screen and some like to tie in a bunch and hang in a tool shed or garage. If you are hanging in your basement be aware of humidity, you may need to turn on a fan. Leave them alone for a month.

Storing

Afterwards, you can either clean them up by cutting back the stalks (unless you want to braid softnecks) and scrub off excess dirt with a rag or you can literally leave as is in a paper bag, dirt and all, until you are ready to cook with them.  Store in a garage or root cellar but you may want to hang in a mesh bag to prevent mice damage. Don’t store them in the refrigerator. Another way to store garlic is to peel the cloves, swirl in a bowl with a little olive oil, and pack in freezer Ziploc bags. Label the bags and place in the freezer. Or make a garlic paste with a little olive oil and freeze the paste.

Garlic is used in so many dishes that it would be impossible to address recipes here so I have listed books about growing and cooking with garlic below.

Don’t Throw Out Your Easter Lily!

Easter lilies (Lilium longiflorum) are bulbs that have been forced to bloom during Easter. If you are given one as a gift, keep it in the house in bright, indirect light. Place it in a room with cool temperatures, 60 to 65 degrees, away from drafts and heating vents. Make sure the container has drainage holes. If it came in a decorative foil, remove the foil to allow the water to drain or cut the bottom out of the foil. Keep the soil consistently moist.

Pinching off the yellow anthers prevents pollen stains and makes the blossoms last longer. Once the flowers are past their prime, remove them.

Easter lilies are true lilies, hardy to zone 4. Here in the DC metro area, you can put your plants in your garden in May after the last frost. Plant them in full sun, in well-drained soil. Plant them at the same depth as they were in the pot. Ideally 3 inches deep with 12 to 18 inches between plants. Treat them like perennials — leave the foliage on until eventually the plants become dormant for the winter. In the spring, fertilize with a slow-release balanced fertilizer or use an organic fish fertilizer.

It may take a year or two for the bulbs to bloom again. However, they will not bloom at Easter, they will bloom in the summer. In nature these are summer bloomers, like other garden lilies.

Pleasantly Scented Paperwhites

Ariel

I placed my order of spring blooming bulbs with Brent and Becky’s Bulbs and expect to get them in late October. I ordered hyacinth, muscari, allium, paperwhites, tulips, and an amaryllis. In addition to the quality, part of the reason why I ordered from this family-owned bulb company in Virginia is that I wanted a better scented paperwhite than Ziva.

Ziva is the most common paperwhite that you will find in the local garden centers. Paperwhites are a type of daffodil that does not need a chilling period. The bulbs are grown indoors, usually in a glass with water and pebbles. In just 6 weeks, they bloom.

Winter Sun

But Ziva blossoms do not produce the “breath of fresh air” one imagines in the winter. Instead, you may be thinking you have a gas leak or worse — rotting meat. What causes this offensive odor?  Indole. Indole exists in trace amounts in gardenias, jasmine, and tuberose (all of which I do like). In these trace amounts, indole becomes more floral and less offensive. It is not surprising that small amounts of indole are used in perfume, such as Chanel No. 5.

However, Ziva has a higher level of indole than others. I do not care for it so I was looking for paperwhites with lower levels and thus better scents. I purchased Wintersun because I like the contrast of the dark yellow cup against the white petals. Others to try are Inball (white flowers), Ariel (white), Nir (white), and Grand Soleil d’Or (yellow with orange cup).

Grand Soleil d’Or

For a better fragrance, try growing something other than Ziva this year. They may not be available in your local garden center but they are available from specialty bulb companies.

Snowdrops: From Simple Flowers to Complex Collections

galanthusEasy to grow, snowdrops are pushing through the snow now. These small bulbs are usually planted in the fall, in masses or drifts. Here in the mid-Atlantic area, snowdrops (Galanthus nivalis) bloom any time from January through March.  Hardy to USDA Zone 4-7, they prefer cool weather, partial shade, and rich soil. They are not fazed by deer but may get relocated by squirrels. By late spring, the green, strap-like leaves die back and the bulb is dormant during the summer.

Snowdrops seem so simple, so humble, like servants to queen daffodils and regal tulips. Here in America, they are a small sign that spring will come soon. In Great Britain, however, snowdrops enjoy a cult status. The English have been breeding snowdrops extensively since the Victorian era, yielding over a thousand cultivars. There are judging events and snowdrop clubs, grand events and exhibits.

To me they are pretty but they look similar. To a galanthophile, each flower is distinct. Galanthophiles collect the cultivars, some of which can be costly. They may also collect other Galanthus species — there are about 20 species that vary in bloom time and size.

Here in this country, we are not able to access a wide variety but a good source for many snowdrop cultivars is Carolyn’s Shade Gardens in Pennsylvania. Another source is David Culp’s annual Galanthus Gala which will be on March 1 & 2, 2024, in Downingtown, PA. David, a well-known breeder, lecturer, and author, has a collection of snowdrops, among other plants, in his gorgeous gardens at Brandywine Cottage. The Galanthus Gala is open to the public, registration is required, and includes speakers and other plant vendors.

Amaryllis: Easy, Holiday Cheer

amaryllis

Growing an amaryllis is easy, just plant and water. Unlike the spring blooming bulbs, an amaryllis bulb does not need a chilling period. It is a tropical plant, hardy to Zones 9-12. Once planted, these large bulbs can bloom in time for the holidays, depending on the bulb. They are pricey, but you can coax the bulb to rebloom the following year.

Now is the time to purchase bulbs in garden centers or order online. An amaryllis can be bought as a single, large bulb for you to pot up; as a gift box of a ‘pre-planted’ bulb (in a plastic container); already planted in a ceramic container as a gift; as a gift box of a glass container with a bulb and pebbles (without soil); and as a waxed bulb.

When the amaryllis blooms depend on several factors: when you plant it, the environment (light, heat), and the type you purchase. To obtain flowers for Christmas, purchase the early blooming bulbs that have been grown in the Southern hemisphere. They take 4 to 6 weeks to bloom so if you plant in November, you may get Christmas blooms. These are labeled “early” or “Christmas blooming.”

If you are not targeting Christmas, try bulbs from Holland (grown in the Northern hemisphere). They take 8 to 12 weeks and bloom from January through March. These are labeled “Dutch grown” or “winter blooming.”

amaryllis

You cannot tell from the bulb which is which so look at the label if the bloom time is important to you. You can also plant several types for months of flowers. For example, you can plant early blooming Bolero, Charisma, Denver, Ice Queen, Mandela or Olaf; then early winter blooming Minerva, Cherry Nymph, Magic Green, or Evergreen; then mid-winter blooming Apple Blossom, Splash, Double King, Exotica, or White Nymph; and then late winter blooming Red Pearl, Red Lion, Spartacus, Nymph, Christmas Gift or Lagoon.

Regardless of the bloom date, amaryllis bulbs (the non-waxed types) can be grown in potting mix or in a vase of water with pebbles. If you plant the bulb in potting mix, make sure the container has drainage holes or put in plastic pots with drainage holes and then into a decorative container or lined basket. Pick a pot 2 inches wider than the diameter of the bulb. For a single bulb, try using a container that is 7 to 8 inches deep and 5 to 6 inches wide. Use a well-drained potting mix, not the soil from your garden. The upper half of the bulb should remain above the soil surface. Water and put in a warm place, around 70 to 75 degrees. Then water sparingly until you see new growth. When growth appears, water more frequently but only to keep the potting mix barely moist, never wet. Place in a sunny window.

Keep an eye on the flower stalks. If they lean, give more light or rotate the pot to balance or stake so they do not topple over. There are special amaryllis stakes that you can insert in the soil to tie to the stalk. Brecks Gifts sells “ladders” as stakes, which little Santa Clause or gnome figures can climb on. Once the flower buds appear, move the plant out of direct sun and into a slightly cooler location.

To grow in a vase of water, place about 5 inches of pebbles, marbles, or glass rocks in the glass, depending on the height of the glass. Place the bulb on top so that the top third is exposed and add a few more pebbles to anchor the bulb. Water enough so the water line is below the base of the bulb. You do not want the bulb to sit in water, but the roots need to be in water. Follow the same directions as above concerning light and temperature. With this method, you need to keep an eye on the water level so the roots always have water.

Then there are the waxed amaryllis bulbs. These are great fun because you don’t water them, you don’t plant them, you just watch them grow. And they do very well. The plant has all the nourishment and moisture it needs from the bulb. With these though, you cannot coax them to bloom again, and you cannot put them in the compost pile because the wax will not decompose. But they are a great holiday gift, especially for kids and the brown thumbs. What is even more fun is that now there are wax designs, like swirls and different colors. Jackson and Perkins and Holland Bulb Farms sell waxed bulbs with colored swirls, heart shapes, and cute tags. Plus there are “sweaters” or “socks” you can buy to cover the waxed bulb. Brecks Gifts sells sweater designs with an image of a polar bear or a reindeer; Viva Terra has Nordic sweaters; and Wind and Weather has a Santa Clause sweater.

For an easy way to decorate the home for the holidays, purchase amaryllis bulbs now. They are guaranteed to put a smile on faces. Here are additional bulb resources.

Planting Tulips in Containers for a Spring Show

China Town, photo courtesy of flowerbulbs.com

I was in a garden store the other day that sported the annual boxes of bulbs on the far side of the wall. Normally I do not purchase tulips because they do not always come back in my Virginia garden. Deer and rabbits eat them; squirrels will dig them up. But I had a new, large container on the deck which deer and rabbits could not access, and these bulbs were only a dollar each, so why not?  I thought it would be fun to create a spring show.

The photo of China Town on one of those boxes grabbed my heart. It is a “viridiflora” type that blooms pink with green streaks up each petal creating a pink/green blossom. The foliage is bluish green with white margins. China Town was awarded the Royal Horticultural Society Award of Garden Merit.

Usually when tulip bulbs are planted in the ground they are spaced 4 to 6 inches apart but in a container, they are planted much closer. I was able to fit 10 bulbs in a 22-inch Rim Crescent Garden container, about 6 to 8 inches deep.

After I planted the bulbs, I watered the container and then added more soil to plant yellow pansies, Johnny jump ups, and a few sprigs of sedum for winter color. This container is in full sun and unless the pansies begin to wilt, I will depend on the rain and/or snow to water the bulbs. Although it is possible to fertilize tulips when planting them in the ground, I did not do it for this container. The potting mix is new and comes with some fertilizer.

Although deer and rabbits are not a problem on my deck, the squirrels think nothing of digging through all of my containers. To deter them, I sprinkled Espoma blood meal. If I had not planted the pansies, I could have kept the squirrels out by covering the top of the container with chicken wire, kept in place with pins, or covering with something sharp like spiny brambles, stems with thorns, or crushed eggshells, all of which would be removed in the spring.

The viridiflora type of tulip should bloom in May and is considered a “late” blooming tulip. The blooms last several weeks and make good cut flowers. China Town will grow to 12 inches, which is short for this category; most grow to 20 inches.

Technically, tulips are perennials but most of the bulbs you see for sale now are treated as annuals here in this area because of our hot summers. There are many types of tulips of course so any of the bulbs you see for sale now could be planted in a large container with drainage holes. And if you see a sale, you can’t go wrong!

Early Spring Bloomers: Dwarf Irises

2014Marchgarden 017

Harmony

It is January and already I can see the green spikes emerging from the mass of dead, brown leaves. Dwarf irises are one of the earliest bloomers in my zone 7 Virginia garden. These irises are only 4-5 inches tall and bloom solitary flowers in February and March. Mine have been in my garden for a long time, nothing bothers them.

J.S. Dijt

J.S. Dijt

Also known as netted iris, dwarf irises (Iris reticulata) are very small bulbs, covered with a fibrous netting. There are many cultivars; flower colors range from light to dark blue or light to dark purple. Preferring full sun and well-drained soil, they thrive in rock gardens, on steps and terraces, in containers, and can be forced to bloom indoors in pots. The flowers can be cut for small desk top vases, bringing early spring cheer to the office or home.

They are available to plant in the fall, along with other bulbs, at local garden centers or through bulb companies. Because they are so small though, buy at least a handful. Plant with roots pointing down, spike pointing up, three inches deep and three inches apart. Hardy to zone 5, they die back in the summer and come back in the spring every year. In my garden, ‘J.S. Dijt’ and ‘Harmony’ have thrived for years with no pests or diseases.

Home for the Holidays: Florist’s Cyclamen

I am sure you have seen the beautiful holiday plant, cyclamen (Cyclamen persicum). Also called florist’s cyclamen, this plant blooms during winter and is a popular gift plant. The flowers, which are high above the foliage, last for several months. Cyclamen is available in a range of sizes, from mini to large, as well as flower colors in magenta, red, pink, and white. Beautiful as it is, it is not an easy plant to grow. Here are tips to prolong the bloom and save for next year. Continue reading

You Too Can Force Hyacinths To Bloom Indoors

Hyacinth Blue Pearl, first flush of flowers

Hyacinth Blue Pearl

It is easy to force hyacinths to bloom early indoors. Hyacinths are relatively cheap bulbs that come in a variety of flower colors: pink, blue, purple, yellow and white. Typically people purchase them in the fall to plant in the garden so they can enjoy their spring bloom. But you can also purchase them in the fall and mimic winter’s cold period by placing in the refrigerator for a few months. They need the cold period in order to bloom. Continue reading

Pleasantly Scented Paperwhites

Ariel

I love growing paperwhites. Paperwhites are a type of daffodil that does not need a chilling period. You can easily find the small bulbs at the garden center now. Most likely you are purchasing a white flowering cultivar known as Ziva. These are relatively inexpensive and easy to grow indoors. Just put a few bulbs in a glass with water and pebbles and voila! You have beautiful flowers in about 6 weeks.

Winter Sun

What’s the problem? The scent. These are not the “breath of fresh air” one imagines in the winter. Instead, you may be thinking you have a gas leak or worse — rotting meat or old diapers. Like cilantro, the fragrance of paperwhites is a “love it” or “leave it” affair.

The culprit? Indole. The fragrance is caused by a chemical called indole, which also exists in trace amounts in gardenias, jasmine, and tuberose (all of which I do like). In these trace amounts, indole becomes more floral and less offensive. It is not surprising that small amounts of indole are used in perfume, such as Chanel No. 5.

Some paperwhites, like Ziva, have a higher level of indole than others. If you find this fragrance offensive, try growing cultivars with lower levels such as Inball (white flowers), Ariel (white), Nir (white), and Wintersun (white with dark yellow cup).  Yellow flowering paperwhites are supposed to be low in indole but the only one I have seen for sale is Grand Soleil d’Or from this list of bulb companies.

Grand Soleil d’Or

Try growing Inball, Ariel, Nir, Wintersun, or Grand Soleil d’Or this year. They may not be available in your local garden center but they are available from specialty bulb companies.
