We've been taking some of the plants outside daily to "harden" them before putting them in the garden, but it is often VERY windy and they've been blown over and damaged in the wind. Also, some nights are borderline warm enough for the tomatoes.
We've created a temporary greenhouse
for them to be out but protected from wind and chill until we can plant them in the garden. This is the same place we are thinking about putting a "real" greenhouse for the winter.
