Tomatoes are popular garden plants because they are easy to grow. They do not need much special care. Here are some tips for planting tomatoes:

Know Your Tomato Type

There are many types of tomatoes, but they are divided into two main groups:

Determinate tomatoes: These tomatoes only grow to about 3 feet tall. They are suitable for growing in pots and containers. All the tomatoes on these plants ripen at around the same time.

Indeterminate tomatoes: These are vining tomatoes that keep growing taller. They produce tomatoes throughout the whole growing season. Because they get very tall, they need to be staked up.

Prepare the Planting Area

Pick a spot that gets full sun. Tomatoes need at least 6 hours of sunlight per day. They also need well-draining soil that is full of nutrients.

Do not plant tomatoes where you grew other nightshade plants before, like peppers, potatoes, and eggplants. This can spread soil diseases to the new plants.

Pay Attention to Temperature and Spacing

Sow or plant tomato seeds when the soil is at 50 degrees F. Temperatures between 65-85 degrees are even better for germination.

When daytime temperatures are around 70-80 degrees F, you can transplant seedlings outside.

But first, you should “harden off” the seedlings for 1-2 weeks. Put them outside for a few hours each day. This allows them to adjust to the outdoor conditions.

Then, plant the seedlings 2-3 feet apart. Plant them 5-6 inches deep in the soil so they can grow strong roots.

Support Your Plants

Tomato plants need support significantly when the tomatoes grow big and heavy. Use stakes, cages, or trellises to hold up the plant.

Water Thoroughly

Tomatoes need 1-1.5 inches of water per week. Water them early in the morning. This gives the plants water for the whole day. Any extra water can evaporate in the sun.

Remove Suckers

Suckers are small new branches that grow between the main stem and other branches. They compete for nutrients with the main plant.

Remove suckers to let the main plant grow tomatoes instead of more branches.
