Only within the last few years have gardeners and chefs shown interest in grape tomatoes. These small, cherry-type tomatoes are distinguished by their oval shape and sweet taste. They’re usually smaller than cherry tomatoes – about the size of a grape. They grow well and are prolific in fruit bearing.
Best Soil for Growing Grape Tomatoes
As with most tomatoes, grape varieties require a loose, nutrient-rich soil that is slightly acidic (around a 6.0-6.5 pH). They also require full sunlight and ample watering.
Proper Care of Grape Tomatoes
Although grape tomatoes are small, the plants are still full-sized. Be ready to grow them as such. They do best when started indoors about 8-10 weeks before the date you plan to move them outdoors. Make sure to transplant them well after the last frost and when the spring sun is warming the soil to nearly 70F daily. And, of course, harden young plants before transplanting.
Most grape tomatoes will need staking or caging for their full productive potential. Spacing 24-36 inches apart in all directions is desirable and supports the plant and individual stems as needed. Moving forward, the plants will become quite crowded once the tomatoes start appearing, so prepare for bountiful harvests.
Fertilization should be done frequently for grape tomatoes, with liquid fertilizer or compost tea being the most suitable options. The liquids should be applied at a ratio of 1:20, with enough water to dilute it down, and compost tea at 1:10.
Ensure that the plants are adequately hydrated as well. Consistent and abundant watering is particularly important for growing healthy and delicious grape tomatoes, as it is for most varieties.
When To Harvest Grape Tomatoes
Expect to see the tomatoes beginning to develop and change color after about 70 days. When they are almost fully red, grape tomatoes will easily detach from the vine. Remember, too much wait time will cause the tomatoes to soften, leading to loss of flavor.
It is crucial the harvest is done meticulously since the fruits bruise easily.
Grape Tomato Pests and Diseases
In the early summer, the pests and diseases that attack grapes will also be interested in your tomatoes. Do not hesitate to use tomato disease prevention methods and insecticide soap. Make sure you water deep and early to reduce the chances of rot and disease, and ensure adequate calcium to prevent blossom end rot.
Tips for Growing Grape Tomatoes
Most importantly, do not plant grape tomatoes until the weather is warm. Tomatoes love heat and cool overnight temperatures will slow grape tomato maturation tremendously.
