Tips For Growing Heirloom Tomatoes


Heirloom tomatoes are annual vegetable plants that have not been crossbred or hybridized for at least 40 years. These plants are open pollinators which means their seeds will produce identical offspring to the parent plant year after year. Each heirloom variety is genetically unique. It has inherited attributes that have taken previous plants years to acquire, such as resistance to pests, diseases, and adaptation to growing conditions and climate. For this reason, along with their sought-after texture and flavor, heirloom tomatoes have become increasingly popular among gardeners.


While there are lots of benefits to cultivating heirloom tomatoes it’s important to know that many varieties require a little more care than their standard hybrid counterparts. Below are a few helpful tips on how to maximize yield and help you select the right tomato.


Prune Indeterminate Heirloom Tomatoes Regularly

There are many benefits to pruning indeterminate heirloom tomatoes.

· Keeps the plant to a manageable size.

· Allows air to circulate throughout the plant, making it less susceptible to mold, disease and pests.

· Allows sunlight to reach the whole plant, maximizing photosynthesis

Heirloom tomatoes are often vigorous indeterminate growers. As they grow, they put out shoots called suckers. These suckers can be found in the v space where the stem and the branch meet. In order to maintain a more manageable sized plant, and redirect energy to the fruit, these suckers should be removed.

Suckers that are two inches or less can be pinched off using your fingers. Anything larger should be removed with a clean pair of sheers, disinfecting them as you move between plants to prevent the spread of diseases. Additionally, branches that are low hanging or touching the ground should be pulled up and supported or removed completely.

Water Evenly and Consistently

Keep your heirloom tomatoes well–watered, especially during the fruit setting stage. Make sure to water slowly and consistently, allowing sufficient time for the soil to absorb the moisture. If plants are subjected to frequent fluctuations in moisture levels, moist to dry for example, the fruit becomes more susceptible to cracking and can develop blossom end rot. If given more water than needed, the fruit can become diluted in flavor.


Water Plants in the a.m. and Keep Leaves Dry

Water heirloom tomatoes in the morning to avoid the risk of burning the plants. When watering, water the soil at the base of the plant and avoid splashing the leaves. When leaves get wet, the water can allow spores and bacterial cells to penetrate the plant and cause infection. Since heirloom tomatoes are more prone to these types of infections, it’s best to keep the leaves dry whenever possible.
