How to Use Alfalfa Meal to Grow Tomatoes


Alfalfa meal is an organic alternative to fertilizers for tomato plants. The chemical triacontanol found in alfalfa can increase the production of tomato plants by up to 60 percent. It contains nitrogen, phosphate and potash needed for growth. Alfalfa helps to stimulate the growth of larger flowers on tomato plants and also can improve the quality of the fruit. Unlike other fertilizers, alfalfa meal can be added to tomato plants any time of the year without compromising their health.

Step 1

Fill a 5-gallon bucket with water. Add 1 cup of alfalfa meal to the water. Blend it well. Let the mixture sit for about a week to make an alfalfa meal tea.

Step 2

Pour one 5-gallon bucket of alfalfa meal tea evenly over each acre of garden area to get the nutrients deep into the soil before transplanting or planting tomato plants.

Step 3

Add a side dressing of dry alfalfa meal to each of the tomato plants six weeks after the initial application of the tea. Measure ½ cup of alfalfa meal for each plant and apply to the soil.

Step 4

Water the soil until it is moist immediately after applying the alfalfa meal. Repeat the application of dry alfalfa meal every six weeks during the tomato plant's growth.
