There are good reasons to grow vegetables from seed. There are so many more choices when you’re buying seeds. Ordinarily, the Garden Center has 50 varieties of tomato seedlings on order. If you look at seeds though, you can chose from 100-plus cherries, currants, slicers and pastes. Another important reason to grow your own is that you are in complete control of how your food is produced, from soil to fertilizers to pest control. And finally, there are few things more delicious than a fresh, warmed by the summer sun vegetable that you have cultivated, nurtured and harvested.
Have we convinced you to give seed starting a whirl? Your first job is decide what you want to grow. All of those choices that we mentioned earlier can be overwhelming. But begin by planting the vegetables that you use most frequently. Zucchini, lettuce and radishes are easy and tasty. And don’t forget one or two of those cherry tomatoes.
Starting seeds indoors isn’t difficult. The challenge is keeping them healthy until it’s time to move them outdoors. Let’s start with the basics. You’ll need clean containers. If you’re seeding a few plants, sow them into small terra cotta or peat pots. Use flats when starting multiples, making sure to mark your varieties. And don’t assume that all potting mixes are equal. Seed starting mixes contain more finely ground ingredients that provide good contact with your seeds, and help to prevent fungal diseases.
Now that your seeds are planted, what’s next? Proper germination and healthy plants require a couple of things. Seedlings thrive in bright, direct light. At a minimum, they’ll need a sunny, south- or west-facing windowsill. If you can’t provide this, don’t despair. You can utilize grow lights. These are light bulbs with a specialized color spectrum that mimics sunlight. There are bulbs available for both spot and tube fixtures.
One of the most common mistakes when planting seeds involves watering. Newly sown seeds need to be consistently moist in order to germinate. Employing plastic seed domes for flats or clear plastic bags for individual pots will ensure that the environment stays humid. You’ll want to remove these as soon as the seeds have sprouted though to allow for air movement. When your baby plants are small, misting them with a spray bottle will prevent them from being washed away. Once the stems are sturdy, use a watering can with a rose. The many small holes will gentle the stream of water.
We’re all hoping for some spring weather. And so are our seedlings. Let them spend nice days outside. When temperatures are above 50 degrees, set your pots in a sheltered spot for the day. An east-facing porch would be ideal. This process is called acclimating and will result in stronger plants. Then bring them in for the night to protect from those temperature dips.
Our last average frost date is May 22nd. Veg plants like lettuce, radishes, peas and members of the cabbage family will be happy outside once night temperatures are reliably in the 40s. But don’t plant out those tomatoes, eggplants and peppers until temps stay above 50 degrees.
