Tomatoes need soil that’s slightly acidic, loamy, and packed with nutrients. The ideal soil temperature for transplanting is 55 degrees Fahrenheit with a pH between 6.0-6.8.


Since most tomato varieties are heavy feeders, they need fertilizer abundant in organic material and have higher phosphorus and potassium levels but low to moderate nitrogen levels. When shopping for fertilizer, you’ll notice products with three numbers. They represent the NPK or Nitrogen-Phosphorus-Potassium ratio. A soil test can help you figure out what soil mix best suits your garden, or you can try an all-purpose fertilizer like 10-10-10.

To learn how to determine what your tomatoes need and when they need it, consult our ultimate tomato fertilizer guide.


It would be best if you watered your plants daily. It’s recommended to spread about 2-3 inches of mulch around the plant, but leave at least three inches of space around the base of your tomato plant.

When you water, water your plant at the base and never on the plant or leaves because doing so may cause sunscald and some bacterial infections. It’s also recommended that you provide 1-1.5 inches of water each week to your plant.

Tomatoes require lots of direct sunlight, between 6-10 hours per day. And while this variety is very heat-resistant, on days when temperatures reach over 95 degrees Fahrenheit, it’s still a good idea to cover the plants with a shade cloth to help prevent sunscald.


Pruning is a very important part of maintaining healthy and productive tomato plants. But you need to know when to do this and what tomatoes need it. To help you with this, visit our pruning tomatoes guide.
