How to Make Tomato Plants Bloom


Tomatoes are a popular garden plant grown throughout the United States. Blossom and fruit production is influenced by the outdoor temperature and time the plants are placed in the garden. General garden care including fertilizing and watering will stimulate blossom and fruit production on healthy plants. Verify the date to maturity for the variety planted, as this will vary the length of time the plant takes to blossom.

Step 1

Add a garden fertilizer to the soil prior to planting the tomatoes. Choose a low nitrogen and high phosphorus type such as 8-32-16.

Step 2

Plant tomatoes once the soil temperature has reach 60 degrees F. Planting too early or late will cause a delay in blooming and fruit production.

Step 3

Apply a soluble fertilizer such as 15-30-15 after planting by mixing 2 tbsp. per gallon of water.

Step 4

Place tomato plants 24 inches apart to prevent disease by increasing air circulation around the plants.

Step 5

Prune the side shoots on late season tomato varieties to focus the plants energy on blossom and fruit production instead of creating bushy growth.

Step 6

Water tomato plants regularly at a rate of 2 quarts water per plant per day. Soak the soil well as this will encourage deep root growth.

Step 7

Place mulch around the plants to prevent weed growth and assist with water retention.

Step 8

Apply a 5-10-5 fertilizer through the growing season if soil tests indicate low fertility. Work the fertilizer into the soil down to 6 inches.
