    Thanks for your suggestions. However, Panama is so humid that many plants rot if ‘closed in’. I try to start some sweet potatoes not long ago… they all rotted within a day. Perhaps it was the plants? but we have a real problem with mold and fungi here. Any ideas?

    I used the egg carton method last year. It kind of worked… You need to really pack down the dirt in the egg holes, or the dirt will crumble when you try to take out your seedling to transplant. The plants grew well in the garden, but it was difficult to get them out of the egg carton. Also, put popsicle sticks at each corner of the egg carton and cover loosely with plastic wrap to give the “green house” effect.

      Don’t take the seedlings out. Just cut the egg carton apart and plant the seedlings. The egg carton base will dissolve into the dirt.

        Make sure you use cardboard egg cartons not styrofoam.

      Next time water your seedlings lightly the night before. Damp soil stays together better. (If you’re using foam egg cartons or anything plastic)
