Growing Flowers and Vegetables From Seed

If you have never grown plants from seed let this be the year you start. You do not need a greenhouse to grow healthy transplants and many varieties can be started indoors over the next month to transplant to the garden this spring.

Want to grow something new or unusual, such as this kohlrabi? Chances are you will have to start it from seed.

What You Can Grow

Many summer vegetable and flower seed can be started indoors in March. Large seeded flowers and vegetables are the easiest to grow and include cucumbers, zucchini, squash, melons, cosmos, marigolds, nasturtium, zinnias, and sunflowers. To get a head start on the season, seeds of these varieties can be sown indoors in mid March to transplant outdoors after the threat of frost.

Slower growing vegetable and flowers should be started indoors a little earlier, ideally from mid to late February to have transplants ready to set out in mid-April. These include tomatoes, peppers, eggplants, basil, impatiens, and begonias. Vegetables and herbs that like cool weather such as parsley, cilantro, broccoli, spinach and lettuce, can also be started indoors at this time and transplanted outside in mid to late March, where they will be able to tolerate light frost.

Containers and Soil

You do not have to buy special containers to start seed indoors. Any type of shallow, 3” – 4” deep container can be used as long as there are several drainage holes in the bottom. Seed can also be sown directly into individual pots such as 6 packs or peat pots. Sowing in individual containers works particularly well for large seed.

Seed should be started in a fine textured potting soil such as a seed starting mix. Lightly moisten the soil before putting it into your pots. Most seed are sown twice as deep as they are thick, so larger seed are planted deeper. Some seed, like lettuce, need light to germinate and are only sown on the soil surface – check the seed packet to see if the seeds you are sowing have any special requirements.

Growing On

Place seedlings in a well lit area after they emerge.

After sowing seeds into containers, water gently and place the containers in a warm (65 to 75 degrees) location. Place clear covers over your seeds or place the containers in plastic bags to keep humidity high, which will speed up germination. If kept covered, seed will usually not need to be watered again until after they have germinated.

Most flower and vegetable seeds will begin to germinate in five to seven days. When seedlings start to emerge, remove the clear covers and place containers in a brightly lit area. You can begin fertilizing seedlings when they are a few weeks old with a weak solution of liquid fertilizer or compost tea. Keep plants moist but not soaking wet and never leave them sitting in a saucer of standing water. A week before you plan to transplant your seedlings into the garden, start placing them outside a few hours each day so they can adapt to outdoor conditions.
