Seeds to Sow: mid-April

20150315By mid-April, we’re right in the heart of the indoor sowing season. Seeds that need a really long head start on the gardening season are already up and growing, those that grow really quickly are still waiting their turn, but it’s just about the perfect time to sow a whole slew of vegetables, flowers, herbs, etc. indoors.

In case you missed a few “appointments” along the way, here’s where to go to see Seeds to sow: early April, Seeds to sow: mid-March, Seeds to sow: early March, etc. Remember, you can sow seeds a bit late and still get good results… it’s sowing too early that is hard to make up for.
