Nevertheless, you can still grow tomato plants in Montana in a proper manner as long as you follow the advice in this article and are also willing to put in some work.

How long does it take to grow tomatoes in Montana?

Due to rather cool climatic conditions and since your tomato plants may not get as much natural sunlight and heat as in many other regions of the US, it may take you between 4 and 5 months to grow tomatoes from seed to harvest depending on the tomato variety you want to grow and on the growing conditions you provide to your plants.

How big do tomato plants grow in Montana?

Even though climatic conditions may not be perfect, your tomato plants can still grow quite big in most parts of Montana if you care well for them and this means you should give them at least 8 feet of space in the vertical so your plants will not be constrained and can get enough space and sunlight to grow in a proper manner.

Can you expect great yields when growing tomatoes in Montana?

While your yields may not be as great as for people growing tomatoes in Georgia or other warmer and sunnier regions, even beginners can still get pretty great tomato harvests in Montana as long as they provide great soil conditions and also give their plants enough space to grow.

When to grow tomatoes in Montana?

Due to pretty long winters, you should not try growing tomatoes in Montana outdoors before May since your plants would just be exposed to frost and would decay sooner or later.

However, one way to start your growing project earlier in the year would be to pre-grow your tomato plants indoors around March and transplant them outdoors later when you no longer expect frost in your region.

Since winters in Montana are pretty cold, growing tomatoes during this period of the year is not a great idea since you would have to spend lots of money on energy for a heated greenhouse and this will just not be worth it in most cases.

Can you grow tomatoes in Montana multiple times per year?

Should you start growing tomatoes in Montana indoors?
