At this time of year I would like to have my garden planted. I try and have seeds planted around the twenty first of May. It's possible to vary the time of seeding as it takes a few days for seeds to germinate . By that time I hope there's no danger of frost.
Plants that have a long growing period and are started in the house or a green house is another issue. If there was frost they would be damaged.
So last night the low forecast was plus 6. I left my tomatoes and corn outside. At 7 AM this morning there was frost on the roof!
Now there are a few things to know about frost. At this time the ground is warm enough that is will not freeze at ground level. So unless it gets very cold plants at ground level should not freeze. Also, if I have my plants beside the house foundation, there's warmth from the foundation to keep the frost away.
So today I just said, "I'm going to plant my tomatoes now matter what." So this afternoon , I planted my tomatoes. There is still risk of frost at this time but you take the risk.
So here we go for delicious tomatoes.
