When to grow tomatoes in Pennsylvania?

You should start growing tomato plants in Pennsylvania outdoors from seed between April and May when you no longer expect winter frost.

If you want to pre-grow tomato seedlings indoors, you may want to start between February and March and transplant your seedlings outdoors later on when it gets warmer outside.

Can you grow tomatoes in Pennsylvania in winter?

Since winters in Pennsylvania are pretty cold, it doesn’t make sense to grow tomato plants in Pennsylvania in winter since you would have to spend lots of energy and use a heated greenhouse which would just not be worth it from a monetary perspective and would also be pretty bad for our environment.

Can you grow tomatoes in Pennsylvania multiple times per year?

Since winters are pretty long and growing seasons are rather short, it doesn’t make sense to grow multiple batches of tomatoes at different times.

Instead, you would be better off focusing on just one single tomato yield and caring for your plants as best as possible during the main season.

What tomato varieties grow best in Pennsylvania?

If you want to grow tomatoes in Pennsylvania, you should choose varieties that get along with cool weather in a proper manner. Those include:

Is it better to grow tomatoes in Pennsylvania from seeds or seedlings?

Since winters are pretty long and growing season rather limited, it may make sense to grow tomatoes from seedlings instead of seed since you would have a higher chance to harvest your tomato plants in time before winter frost arrives and growing season would be over.

Should you start growing tomatoes in Pennsylvania indoors?

If you want to see results rather early in the year, it can make sense to start growing tomatoes from seed indoors early in spring and transplant them outdoors later on when they are still rather resistant to the cold and pests of many sorts so they can strive in their natural environment and are ready to harvest rather quickly.

How to water tomato plants in Pennsylvania?

Since it often rains in Pennsylvania during spring, you often just have to water your plants a single time per week during cool spring months.

However, once it gets hotter outdoors and your plants get bigger, you may have to water your tomato plants on a daily basis so they don’t dry up and provide you with decent yields at the end of the growing cycle.

Do you have to protect tomatoes against the sun in Pennsylvania?

Since radiation is not really extreme in the early months of the year in most parts of Pennsylvania, there is no need to actively protect your tomato plants against the sun.

Instead, you can just let them grow in a natural manner and once your plants get bigger, they will also become more resistant in general.

Will wild animals feed on tomatoes in Pennsylvania?

You may have to keep away rabbits, mice and other wild animals when growing tomatoes in Pennsylvania and you may therefore take some protective measures like installing a fence or using a scarecrow to deter those hungry intruders and keep them away from your plants.

Tomato pests & plant diseases in Pennsylvania

Thrips, slugs and aphids are just some of the annoying pests you may have to deal with when growing tomatoes in Pennsylvania.
