Growing Microgreens for Flavor and Nutrition

mustard microgreens

Now that winter is coming, you can still grow your greens, just indoors. Growing microgreens is a fun, cheap way to grow nutritious vegetable seedlings for sandwiches, wraps, soups, and salads. Microgreens are the shoots of edible plants, requiring very little space and minimal cost. Microgreens differ from sprouts. Microgreen seeds germinate in a growing medium and after one or two weeks, the “micro” stems and leaves are cut to the soil level and eaten. Sprouts are seeds grown in a moist container—no soil. After a few days, the root and seed are harvested and eaten.

There are different ways to grow them and many kits for sale. Basically, the seeds can be grown without soil (hydroponically) or with soil. If grown hydroponically, they may germinate in a moisten disposable mat or in a container with a mesh between the seeds and the basin full of water.

If grown with soil, only a few inches of soil are need but the container has to have drainage holes and a bottom tray to catch the water. There are plastic kits that can be washed and re-used with each sowing or you can create your own. Simply re-use plastic containers from the grocery store, such as clam shells for berries and baked goods.

Poke a few holes for drainage and fill with bagged, sterile, soilless growing medium. Do not use the soil mixes that have moisture beads or fertilizer (no need for fertilizer) and do no use soil from the garden. The mix specifically made for starting seeds works best. Fill the container with 1 to 2 inches of mix and water thoroughly.

Because seed germinate and grow at different rates, it is best to use one type per container. Cover the surface with seeds and press down with your fingers to put them in direct contact with the moisture. Place the container on top of a tray to catch the excess water. Cover with another container to increase the humidity level and warmth. Always label containers with the plants’ names and keep records so you learn how soon you can harvest and what you like to eat.

After the seeds germinate, remove the cover and provide light via grow lights, fluorescent tubes, or a south facing window. If you do not have a very sunny window, you may have to rotate the container for the stems to grow straight. If the top level of the soil dries out, water by either misting the top or putting the container in a pan of water so the water is absorbed via the bottom drainage holes.

The first set of “leaves” you will see will not be the true leaves — they are the cotyledons or the seed leaves within the embryonic seed. If the plant grew outside for the mature fruit or vegetable, these would eventually shrivel and disappear. For many microgreens, you can harvest at this stage because there is plenty of flavor in these “leaves” and stems. For example, you can harvest radishes at this stage because you will taste plenty of spice and the stems will be crisp.

With some plants, you wait until the second set of “leaves” appear, which will be the first set of true leaves. For example, you will want to harvest cilantro at this stage because you get more flavor in the true leaf. At this point, the seedling is probably 2 inches tall.

Harvest by cutting straight across with scissors a centimeter above soil line. You can cut what you need and wash or cut all of it, wash, dry, and refrigerate in a plastic bag for a few days.

The best seed for microgreens germinate quickly and produce tasty shoots and leaves. There is no such thing as a microgreen seed; microgreen is really a stage in which the plant is harvested. However, you may find seed packages sold as “microgreens” because the package is a mix with similar germination rates. Popular seed are kale, mizuna, mustard, radish, carrot, cress, arugula, basil, onion, chive, broccoli, fennel, sweet pea, celery, bok choy, and Asian greens. The only seeds that do not work well are lettuce and spinach. Microgreens are a great way to use up your old seed packets because you sow densely so if there is a reduced germination rate, you would not notice. Or purchase fresh seed from local independent garden centers or order online from any of these companies.

Growing microgreens is fun and easy. The more you determine the flavors you like the more you can set up a system where you are sowing seeds on a weekly basis to feed your family nutritious and colorful vegetables year round.

Twenty-One Tips for Growing Tomatoes Successfully

By now you should have started your tomato seeds indoors under lights. This is just if you want a head start of course, it is not necessary. You can also purchase tomato plants but be aware that the night temperatures are still cold for them to be out in the garden now. They prefer warmer weather. Waiting to plant tomatoes until the beginning of May or Mother’s Day will give you the best results. For tomato success, read these twenty tips for growing tomatoes in the Washington DC metro area.

First, know what you grow. Tomatoes have determinate or indeterminate growth habit. Determinate types produce fruit at the end of the branches so most of the crop ripens at one time and you will have one or two harvests per growing season. This is advantageous for canning. The determinate types are more compact and are better for containers than the indeterminate tomato plants; however, you may still have to stake the vines or add a trellis. Indeterminate plants produce fruit along the branches so you can pick tomatoes all season long. They can be large, vining plants; a support system such as hoops or stakes should be used.

2. Tomatoes come in many sizes, shapes, colors, and flavors. Grow what you like to eat or use in the kitchen. For example, determine if you prefer to use tomatoes for salad, snacking, pasta sauce, sandwiches, etc. There are more specialized varieties for specific uses such as the Sun Dipper pictured to the right which is elongated to make it easier to hold while dipping into a dip.

3. If you are limited to containers, grow the determinate type and use a container at least 5 gallons large with drainage holes or an Earthbox. Or look for varieties especially bred for containers such as window box types (usually these will be the small, cherry types).

4. Determine if growing an heirloom plant is particularly important to you. Heirlooms may be tastier, and seeds can be saved for next year, but these plants may be more susceptible to diseases. Hybrids are often bred to be disease resistant. However, if you save and sow the seed next year, the plants may not have the same traits as before. Seed catalogs and packages often have letters after the plant’s name to indicate disease resistance. For example, F is for fusarium, V for verticillium, LB for late blight, TMV for tobacco mosaic virus, and N for nematodes.

5. Days to maturity is the number of days it will take on average for a transplant to produce a tomato (fruit) when planted in the beginning of the summer. It is not the number of days from seed. This varies quite a lot with tomatoes from plants with a lower number of days which will provide an early season harvest, to mid-season, to those with larger numbers, resulting in a late season harvest in late summer. If you have the space and want tomatoes throughout the growing season, you can plant early, mid, and late season plants.

6. If starting from seed, sow seeds about a month before average last frost date (Mother’s Day here). Start inside under lights. When the seedlings produce a set of true leaves, you can pot up the plant into a larger container and put outside for a few hours a day. Gradually introduce seedlings to more daylight and more time outside in order to harden off before putting in the ground. Hardening off is the process of acclimatizing seedlings to higher light levels, cooler (than your home) temperatures, and breezes so they can withstand being outside. Here is a link to tips for starting seeds indoors.

7. At first the nighttime temperatures may be too cold (forties and below) to leave these transplants outside so you may have to bring the pots inside for the night.

8. Seedlings and transplants in the spring may develop purple tinged leaves which means cool temperatures are preventing phosphorus absorption. In the summer, when it gets warmer, they will grow out of this so no need to do anything.

9. Tomato plants need at least six hours of sun and like warm soil, which is why it is best to put the transplant in the ground after Mother’s Day. If you plant them in cold soil, they will sit, unhappy.

10. Tomatoes like fertile, well-composted soil, not clay. In this area, you may have to amend your garden bed with compost. In the spring, a raised bed and a container will have warmer soil than the ground.

11. When nighttime temperatures are in fifties and the transplant is hardened off, plant in ground. For the indeterminate types, insert staking or hoops immediately after planting. Make sure you have spaced your tomato plants so there is a minimum of 2 feet apart for air circulation (to decrease a pathogen’s ability to spread).

12. Tomato stems will develop roots if covered with soil. Some gardeners will bury as much stem as possible to encourage root production. The theory is that if there are more roots, the plant will be able to take up more water and nutrients. Some people lay the transplant down on the ground, horizontally, burying the stem, but leaving 1 to 2 set of leaves above ground. Some people plant vertically, but very deep, leaving 1 to 2 sets of leaves above ground. Before you submerge the stem, strip off the leaves and little branches that would be underground.

13. A lot of gardeners add calcium in the form of crushed eggshells to the soil or 1/4 cup of lime before planting to prevent blossom end rot. If you do not do this, then pick a fertilizer especially formulated for tomatoes because it should have the added calcium.

14. In the beginning of the summer, mulch with straw, leaves, or compost to prevent weeds and to keep a constant level of soil temperature and moisture. Try Maryland’s Leaf-Gro; do not use composted manure.

15. Tomatoes will need to be watered so make sure a hose or watering can is available. Water the soil, not the plant, and water in the morning to decrease possibility of fungal disease. It isn’t that tomato plants need a lot of water, it is that the soil moisture must be consistent, and not fluctuate often. Mulching helps with this.

16. In mid-summer, tomatoes will need to be fertilized, especially if grown in containers. Espoma has organic Tomato-Tone and Neptune’s Harvest has a Tomato and Vegetable Formula.

17. To obtain fruit, temperatures must be above 55 degrees at night but temperatures of 75 or higher will inhibit fruit set and may cause blossoms to drop. However, there are heat-tolerant varieties.

18. Tomatoes are wind pollinated. Some gardeners hand-pollinate with a paintbrush if they feel the plant is not setting fruit. All the more reason why there should be good air circulation. Harvest frequently to encourage plants to produce fruit.

19. Pruning is optional, but only indeterminate plants should be pruned. Pruning here refers to removing the side shoots or suckers. Some gardeners do this to increase or to have more uniform fruit size and to help tomatoes ripen faster. It will not increase the number of tomatoes. If prune, start when plants are about 2 feet tall and suckers are small. Do this when the plant is dry, not wet from rain.

20. If possible rotate crops to prevent soil-borne diseases. If your tomato plants are having problems, check out the Virginia Tech Extension site on growing tomatoes, tomato diseases, and tomato pests; and the University of Maryland Extension site on tomato diseases, pests, and nutritional issues, growing tomatoes, and tomato topics; or contact your local extension agent.

21. Pick the fruit when it begins to color and bring inside. Ripen at room temperature and do not put in the refrigerator. This also prevents animals from eating the fruit before you do.
