I started my tomatoes indoors on March 20, 2011 and transferred them to their own pots on April 8th. This week it was warm enough (ok, just barely) to start putting them outside a few hours every day.
The Tumblers are doing great; I’ve already transplanted some of them to larger pots as you can see in the photo. I made sure to plant then even deeper in the new pot, burying another 2-3 inches of the central stalk.
When I put the tomatoes out to harden them off, generally about two weeks before last frost, I begin by only exposing them for a couple of hours per day. Ideally they shouldn’t get any significant wind or direct sunlight for the first while. Hardening off is critical to the success of seedlings which have been raised in a safe indoor environment devoid of significant air circulation and UV radiation.
My grocery store began using these new non-refillable water bottles a few months ago. The deposit is a paltry twenty-five cents, so I decided they would make great cloches for the bigger tomatoes. I use the top of a juice bottle for the smaller ones.
It’s exciting to think that I’ll be able to transplant many of my seedlings to the garden in only a couple of weeks!
