Why Start Growing Vegetable Plants From Seeds Indoors?

The first step you need to take is to decide whether you want to start your garden from seeds or from young plants (“transplants”) from a local nursery.

Buying a transplant is certainly much easier and more practical. However, you are limited by variations of plants and flowers. Seeds, on the other hand, offer a much wider range of varieties.

These are the things you need to pay attention to:

  • Buying seeds is usually cheaper than buying individual seedlings from nurseries.
  • By planting the seeds you have control over the way the young plant is grown.
  • The seeds offer a wider selection of varieties, flavors, and textures.

After all, it is not a bad idea for beginners to start with already established plants. This shortens the time that would be spent on germination and reduces the amount of plant care.

When Should I Start Planting Vegetable Seeds Indoors?

The most important thing is to know the date of the last possible frost in the place where you live. As a rule, most annual vegetables should be sown six weeks before the last frost.

In addition, try to avoid premature sowing as you will eventually have to transplant the seedlings into larger pots multiple times. Finally, the seed package will often indicate when the seed should start indoors.
