How to Use Multi Vitamins in Tomato Plants

Plants and animals have some of the same nutritional needs. Tomato plants can suffer from calcium, magnesium, potassium, iron and manganese deficiencies just like humans can. Many of these minerals are found in multivitamins manufactured for human use. In fact, many organic vitamins pull these minerals straight from tomato and other vegetable plants. You can resolve some vitamin and mineral deficiencies in plants, such as tomato plants, by giving them a multivitamin.

Send a sample of the soil that your tomato plants are growing in into your local county extension office to be tested. The report will reveal the mineral content of your soil. While not harmful, a multivitamin supplement will be unnecessary if your soil is quite fertile. However, if you find that there is a dearth of a certain necessary mineral in your soil, look for a multivitamin with high amounts of that mineral.

Find an appropriate multivitamin. The best multivitamins for plant use are organic and contain minerals derived from plant sources.

Crush the multivitamins into a fine powder using your mortar and pestle.

Mix the water, sparkling water and crushed multivitamin in the large container.

Transfer the solution into your watering can. Water your tomato plants deeply at their base until the soil is saturated but not soaking.

Water your tomato plants with the multivitamin 3 to 4 times per growing season. The vitamin C found in most multivitamins can help your tomato plants with weather changes. If possible, water them with multivitamins a week or so before the seasons change.

Tomato Plants Get Too Big?

Nitrogen is a key element needed for chlorophyll production; photosynthesis and foliage growth depend on healthy amounts of nitrogen in the soil. Although you have a large and bushy ornamental tomato plant, the excess nitrogen impedes normal flower and fruiting development. Staking or caging your tomato is the only way to retain a large plant with successful fruiting. In addition to preventing disease and pests attacking the plant, supporting the tomato improves air movement between the leaves for transpiration. In fact, the lack of light encourages the tomato to grow tall in search of sunlight, but it does not have the energy reserves to generate new foliage for photosynthesis. Because tomatoes enjoy warmth, a container plant works well in a south-facing window or on a sunny porch.
