This article will walk you through the ins and outs of planting seeds indoors. Whether you're a seasoned gardener or just getting started, this post will provide you with the knowledge and tools you need to cultivate a lush and productive garden.
What Seeds Can You Plant Indoors?
When it comes to indoor seed starting, the possibilities are endless. However, it's essential to choose seeds that are well-suited for indoor cultivation. Here are some popular options:
Herbs
Herbs like basil, parsley, and cilantro are excellent choices for indoor planting. They're versatile, easy to grow, and add fresh flavors to your dishes. To give you a longer growing season, it's best to start basil off indoors in warm conditions. Sow several batches from late February through to mid-summer in small pots or seed trays, at a temperature of about 18°C (64°F). For parsley, You can start seeds off indoors in a greenhouse environment or on a sunny windowsill from early spring onwards. When it comes to cilantro, if you're like some people I know, who can't wait until late spring to harvest some fresh cilantro leaves, you can start cilantro indoors in peat pots about 2 weeks before your average last frost date. Peat pots are great because they can be directly transplanted into the garden when your soil is workable. I love growing Cilantro from seed because they have a fast germination rate. They germinate in about 7 to 10 days!
Tomatoes
Tomatoes are a favorite among indoor gardeners. Starting tomato seeds indoors allows you to enjoy homegrown, juicy tomatoes earlier in the season. Because tomatoes take about 6 to 8 weeks from seedling to transplant, seeding indoors should take place between mid-March and April 1.
Peppers
Bell peppers and chili peppers thrive indoors, providing a burst of color and flavor to your recipes. Most seed packets recommend starting pepper seeds indoors 8 to 10 weeks before the last average frost date. When I know the weather will be warm enough for consistent nighttime temperatures of 50°F, I’ll usually transplant my seedlings from late May or early June.
Flowers
Flowers, my favorite seeds to start indoors! Marigolds, petunias, and pansies can be started indoors to add beauty and charm to your garden.
Greens
Leafy greens such as lettuce and spinach are perfect for indoor cultivation, ensuring a steady supply of fresh salads. Start lettuce seeds indoors 3 to 4 weeks before your area’s last hard frost — which is around 30 degrees overnight. Some varieties, especially iceberg-type lettuces, can be started indoors even earlier, about 8 weeks before the last frost. Be sure to read your seed packet for the recommended time for that specific plant.
