It is time to start little peat pots . Don't spend large sums on starter pots. That's baloney!  Instead, crack your eggs open at the tip when you cook them.You now have an excellent starter pot that will leach calcium into the potting soil.I cut my egg cartons into single rows. That width fits perfectly on my windowsill. These eggshell peat pots are 2 weeks old and the tomato plants are doing just fine.
