When to grow tomatoes in Illinois?
If you want to start growing tomato plants indoors, you can start as early as March, raise your plants to a certain height and transplant them outdoors once you no longer expect any frost.

Can you grow tomatoes in Illinois in winter?
Since winters in Illinois are pretty cold, you would have to grow your tomato plants in a heated greenhouse with plenty of artificial lighting and this would be really expensive and also pretty bad for our environment and may therefore just not be worth it.
Can you grow tomatoes in Illinois multiple times per year?
Since winters in Illinois are often pretty long, it may be advisable to just grow one single batch of tomato plants per year during the main seasons since you would get much higher yields while your tomato growing projects during the off-season will often not be a real success.

Should you start growing tomatoes in Illinois indoors?
Due to rather cold spring weather and frost early in the year in many regions of Illinois, it makes sense to start growing tomato plants indoors and transplanting the seedlings outdoors later in the year.
How to water tomato plants in Illinois?
Since it is pretty cool in spring and your plants will also get lots of water from precipitation, you may not have to water your plants pretty often during those early months when they are also still pretty small.
However, things change pretty quickly once your plants get older and it gets hotter outdoors and you may therefore have to water your plants on a daily basis during summertime.

Since sun intensity is not really serious in the early months of the year in most parts of Illinois, you also don’t have to actively protect your plants from excessive sunlight and can just let your tomato plants grow in a completely natural manner and once they get bigger, they will be able to deal with lots of radiation on their own.
Will wild animals feed on tomatoes in Illinois?
Rabbits, raccoons, deer and birds are just some of the animals you have to protect your tomato plants from in many parts of Illinois since in case you don’t, chances are your plants will just be gone sooner or later and your tomato growing project will be ruined.
