You must ventilate well.īordo Copper Spray applied regularly in late summer prevents the fungus that causes Late Blight to germinate. In a greenhouse or under a cloche, humidity can build up so high that the fungus will destroy plants in 24 hours.
Our cloche system is excellent for keeping rain and moisture off the plants. Use drip tape for watering and avoid splashing the leaves. Prevention is key as there is no cure for the disease. Sometimes a bluish grey mould grows on the underside of infected leaves and on the fruit cankers. Often the fruit manages to almost reach maturity before the cankers take over. Blight infected tomatoes can have a fishy smell. Brown cankers develop on the stems and fruit. These are greenish black and irregular in shape. It begins as leaf spots before spreading to stems and fruit. Digging in bonemeal, dolomite lime and a balanced organic fertilizer such as Gaia All Purpose Blend 4-4-4 will help prevent this disease as will an even and regular watering schedule.Īn airborne fungal disease causes Late Blight. Early fruit show the affects sooner than later fruit. The tomato plant can’t take up enough calcium resulting in an unbalanced potassium-to-calcium ratio. When the plants are too dry for a period followed by over watering, this encourages fast growth. Calcium deficiency can happen when there is uneven watering. Internal blackening can occur without the characteristic end rot. Sometimes a secondary infection can occur at the damaged area, which turns it mushy and wet. It appears as a brownish dry and firm sunken area. As the name of the disorder indicates it occurs at the blossom end of the fruit. Their suckers are not normally removed, though some trimming helps with ventilation.īlossom End Rot is an environmental disorder caused by a calcium deficiency. Determinate varieties normally set fruit in a concentrated time period. Remove any suckers (stems growing from the crotch of leaves) to keep the foliage under control, and they will set a later crop of larger fruit. Indeterminate tomatoes continue to grow and produce fruit until they are killed by frost. Vibrating the plant shakes pollen loose within the flowers, which then self-pollinate. Tomatoes do not rely on insects for pollination. If tomato plants are grown under cover, you can encourage pollination and fruit set by tapping the stem from time to time. Stop watering around the end of July to encourage the fruit to ripen. This will encourage greater root growth, helping with both nutrient uptake and the plants’ ability to stand up to dry conditions. At the time of final transplant, plants can be buried up to their first pair of true leaves. Bush types benefit from the support of a tomato cage in order to prevent sprawling.
Vine varieties will require some kind of support such as a wire to grow up, or a trellis to be tied to as the plant grows.

Tomatoes are tropical plants so they require full sun and lots of heat. Regular watering is vital, but don’t let the plants sit in water. By the same token, lighter soils warm more quickly, so transplants can go out sooner. Adding glacial rock dust will supply all the calcium they will need. The nutrition from heavy clay soils is excellent for tomatoes, but they are slow to warm, so transplanting should be done later. Dig in finished compost and manure, and add 1 cup balanced organic fertilizer beneath each transplant. Tomatoes like fertile, well drained soil that is rich in organic matter. Fruit will taste bitter if picked too early, and if left too late may become mealy. A slight yellowish blush in colour and a firm feel with a bit of "give" are signs the fruit is ripe for picking. For best flavour allow Green Zebra organic tomatoes to fully ripen on the vine. Vines show some resistance to Septoria Leaf Spot.
