Heirloom tomatoes have characteristics some people might consider disadvantages. The fruits are generally thinner skinned and softer than those of hybrids, so they're more liable to crack or bruise. That makes sense, since heirlooms were selected for home gardens rather than for commercial production.
Black, Brown, and Purple Tomatoes
These colors offer high levels of lycopene, vitamin A, vitamin C, and potassium, so they are nutritionally complete in comparison to lighter colors. Black, brown, and purple tomatoes are also packed with flavor and often have a surprisingly sweet taste.
Heirlooms have not had their genetics professionally curated and evaluated. Consequently, heirlooms tend to have more susceptibility to disease, lower production, and certain cultivars can be more “finicky” if growing conditions are unfavorable.
Because most heirloom tomatoes are vigorous growers, they do need to be pruned more often. Pruning (also called "suckering") is important because removing suckers provides better air circulation, which helps prevent foliar diseases. Pruning also encourages larger fruit production at the top of the plant.
All heirloom tomatoes are open pollinated, which means they were created naturally through pollination of insects and wind – no human intervention. At SummerWinds Nursery, we have a great selection of heirloom tomatoes of all shapes, colors, textures and taste.

You can expect to get about 10 to 20 tomatoes per plant, depending on the type you're growing.
2) lack of water (wilting) can cut down on fruit development. 3) high temperature stress will limit fruit size. This is very common in the hot, humid southeast, especially in May and June. 4) shading during the cloudier months prevents full development of fruit.
Daily intake of tomatoes can provide a great lift to wellbeing, along with improving the flavor of food. Tomatoes are wealthy in natural nutrients and minerals, such as Vitamin A, K, B1, B3, B5, B6, B7, and vitamin C.

A recent study found that consuming 14 milligrams a day of lycopene can improve fertility in healthy young men by about 40 percent. Lycopene has been shown to reduce pain to a degree similar to that of ibuprofen medication.
'Gold Medal' (beefsteak, indeterminate, heirloom c. 1920) is arguably the top bicolor for taste. The giant 1-3 lb fruits are perfectly marbled with red and yellow and are large, meaty, and juicy. It has won lots of taste tests where it has been described as luscious and superb.
Generally, they vary widely in size, shape, color and taste but typically have higher sugar content and some say a much better tomato flavor than conventional varieties.
So, why are heirloom tomatoes more expensive? There aren't as many of them, they need quite a bit of care and time to ripen, and they're hard to ship. Every one of these factors contributes to a higher cost per tomato.
Plant your heirloom tomatoes in full sun, or at least six hours of direct sunlight a day. Some experts recommend eight hours. There's one caveat: Many gardeners start heirloom tomatoes by seed indoors. If that's the case, harden off your seedlings by gradually increasing their time outdoors.
A tomato plant typically lives for one growing season (6–8 months) when grown outdoors, but when nurtured in ideal or controlled growing conditions indoors, tomato plants can survive between two to five years.
So by burying more of the stem when planting tomatoes, we are allowing these roots to grow. This can greatly benefit the plant in a couple ways. One of the most important is that it allows for stronger root structure and growth.

Tomatoes are prone to magnesium deficiency later in the growing season, which can show with yellowing leaves and diminished production. Ultra Epsom Salt treatments at the beginning of their planting and throughout their seasonal life can help to prevent and remedy magnesium deficiency in your tomato plants.
Heirloom varieties are open-pollinated. This means you can save seeds from heirloom tomatoes, plant them, and expect them to grow into new tomato plants. If two or more varieties are planted close to one another, you might just end up with a new variety!
Heirlooms are indeterminate. They will continue to produce until the frost kills the plant. Most will also grow up to 8 feet tall or more. They need staking and a very large pot or to be planted in the ground.
Beefsteak tomatoes, which can be either heirloom or hybrid, are notable for their size—they can weigh in at over a pound each, with a diameter of six or more inches—and their texture: They have smaller seed cavities than other types of tomatoes, giving them a greater ratio of flesh to juice and seeds.
