Despite the cold winter we had this year and the cool, wet spring we have had so far, I’m still looking forward to a return to more seasonal temperatures by my warm season plant out date of May 17. This is the date that there is a 10% or less chance of frost (one year in ten there may be a frost after this date) in the Clarksville area of Maryland.

So, assuming that warm weather will return, I have started all of my transplantable warm weather vegetables on schedule (click on “Seed Starting and Planting Dates” in the top left corner of the page). By starting these vegetables indoors under fluorescent lights, I get a 4 to 8 week head start on the summer season and, thus, earlier yields from these crops. The latest vegetables started were my cucurbits. I sow seeds of my cucurbits about 4 weeks prior to my plant out date in 4 inch pots, filled with soilless mix, 3 or 4 seeds to a pot. Once they sprout, I usually thin the pots to the two strongest plants, keep them under the lights for two weeks, then move them into my cold frame for a week of hardening off.
Cucurbits are easy to start and one of the few vegetables which can be started without fluorescent lights. Just start them in a warm area and after they sprout, sit them outside in a sheltered, sunny area. Just remember to bring them is at night or when temperatures dictate.
I have an affection for the cucurbit family and have started lots of them. What you see in the flat are several varieties of cucumber (Iznik, Sweet Slice and Diva) summer squash (Black Beauty, Costata Romanesco and Ambassador zucchini and Early Prolific Crookneck), melons (cantaloupes Tasty Bites and honeydew Dulce Nectar). winter squash (Butternut), Pumpkin (sugar) and watermelon (Moon & Stars)
