10 Easiest Seeds to Start Growing Indoors

One reason that people start seeds indoors is so they can get a jump start on the gardening season. 

This is especially good to do if you live in a region with short growing seasons.  It will give you a few more weeks of growing time. The question is which seeds are the easiest to start indoors.

Why Start Plants From Seeds Indoors.

In addition to getting a head start on the growing season, it is generally cheaper to start plants from seeds if you are going to grow a lot of them.  When buying plants from a nursery, sometimes they are grown nicely while others are poor quality.  When growing your plants from seeds you can have control over how it is grown.  Some nurseries have a wide variety of plants while others do not so when you use seeds you have more variety.

Things to Consider Before you Start Growing Seeds

The first thing you need to do is know just what you want to grow to make sure that you have enough pots or containers in which to grow them.  If you are starting your seeds in late winter you might consider getting a grow light because most of the time, for seedlings to grow you will need 6-8 hours of direct sunlight.  The grow light will also help to keep the seedlings from being too leggy.

Make sure that the containers you use are clean.  You can get peat pots, seedling flats, and other growing containers but egg cartons you already have make good containers to start growing seedlings.  If you use these, make sure that you are poking holes near the bottom in the sides.  This is to let any excess water come out.  Before moving your plants to the garden you may have to transplant them to a bigger container so you need to keep this in mind, especially if you are starting them in egg cartons.

Be sure that you label your containers so you know what you have planted.  This can be frustrating trying to transplant them outdoors and you are not sure what you are transplanting.  You should fill your containers with a moistened potting mix that is made for growing seedlings but not regular potting soil as it may not be fine enough for the seedlings to push through.
