This year I went crazy with water melon starts. About three weeks ago I started one flat each of 15 varieties. Many of these seeds are heirloom varieties from Seed Saver's Exchange.
Some of the seeds were small quantities and a flat was all I had. Others I had a larger quantity and so I also direct seeded some.
I have been bringing transplants to the farmer's market. So it you want to try any of these you can get them there.
Here is how you do it.
