Hi Caragh,
Welcome!
I'm no expert (this is my first year gardening too), but I'm am successfully
growing 2 tomato
plants right now. I think the answer to your questions will depend on several factors. When did you
plant them? How many months of warm weather are left in your season? What kind of tomatoes are you
growing?
Tomato
plants generally take around 65-80 days to mature, and they need about 6 hours of sunshine per day. There are some guidelines about minimum and maximum temperatures, but I don't know that information. I'm sure someone will answer about that.
First the
plants will make
flowers, then the tomato develops where the
flower joins to the
plant, then the
flower falls off. To give you a idea (but I don't know if this is typical) my cherry tomatoes have been green and hanging on the vine since mid June. None have turned red yet. My regular tomatoes are on about the same schedule.
You mention you have some tomatoes
growing on your windowsill. I want to caution you that they will grow very tall (mine are taller than I am), so they need a sufficiently large pot (mine are in 20" diameter containers), and plenty of vertical space as well.
Best of luck to you. I'm sure you'll find the help you need on this forum.
