Hello, i read that i can plant tomatoes until the end of mai but most people say that i need to transplant my tomatoes until march. I bought 8 tomatoe plants (1 determined, 3 cherry tomatoes, 4 beefstake or normal sized tomatoes) will the produce any tomatoes? And if not should i try to keep them alive for the fall season (by putting them in the shade or my garage or inside my home)?

Josef, Tomatoes in 9a or 9b can almost be grown every month, but tomatoes die if there is a frost, and stop growing/producing if the temperature is above 95F. Since this the beginning of summer, it is not advisable to plant tomatoes until after the heat of summer. If you have young tomatoes planted try and shade them, or keep them healthy so they can resume growing after the summer heat has passed.

My tomato plants are ready to go into raised bed. But the temperature drops to mid 40s at night. Is it okay to plant them out yet. Thanks

Tomato plants can handle night temps in the mid 40s but you should harden them off a bit if they're used to a hothouse. If you want to baby them so they'll grow a bit faster, consider covering them at night with horticultural fleece, though you shouldn't actually *need* to unless frost threatens or the night is forecast to be very windy.

I would wait until it warms up more - more like in the 50's

I transplanted my tomatoes a week ago and I notice today that a few of them are already showing signs of flowering. The plants are still relatively small. Should I pinch off these very early buds.I am sure there are experienced gardeners out there who know what to do. Please advise.

They have been in a pot where the nutrients have nearly run out so the plant is trying to reproduce its self, by going to seed. Make sure you have good rich soil. You need to prepare the soil well before planting out.

What type tomatoes are best or grow area 10a and should they be determinate or indeterminate?
13 Feb 21, SarahM (USA - Zone 10b climate)
In 10b here. You can grow either. Determinate only grow to size, produce fruit then die off. You would grow them in succession to get get tomatoes all season. Indeterminate tomatoes require space as the plants just keeps growing [kinda like a vine] while we have long days of sunlight. Better to decide what type of tomato fruit you want [paste, slicer, etc...].
