![]() We believe lack of feed is the main reason that people fail in growing a decent crop of tomatoes. Increase the strenght of the feed as the plant grows. Again this will all depend on weather and risk of frost! Plant under cloches in early May, otherwise leave till June and plant out then. Plants for outside should be hardened off, before planting out. Greenhouse grown plants can be planted April onwards.Because tomatoes like the warmth you will always get a earlier and bigger crop from greenhouse grown plants. Once the plants are 20cm tall, they can be planted in their final positions.When the plants have reached 2 trues leaves, begin feeding weekly with a weak tomato feed.Prick out into 9cm pots once the seedlings are big enough.Seedlings should start showing around 7 days if you have the right temperature. Lightly cover over and keep moist at a temperature of 18 degrees. Sow the tomato seed individually in cell trays, using a good quality seed compost.Although you can sow seed from as early as late December in a heated greenhouse, it is more usual for most to sow in a unheated greenhouse or on the kitchen windowsill in March / April for planting out April / May.

Spores will also overwinter in infected seed potatoes, so you should only plant certified disease-free seed potatoes. The spores only overwinter in living plants, so remove any volunteers and solanum weeds. If you must use sprinklers, water in the morning or early evening, so the leaves can dry out before nightfall. It is important that leaves don’t stay wet for long periods, so ideally you should use drip irrigation. To minimize the effects of this disease, make sure the plants have good drainage and air circulation (staking and pruning can help with tomatoes). Newer varieties specifically bred for resistance include Ferline’ F1 hybrid and 'Fantasio’ F1 hybrid. Resistant tomato varieties include: Stupice, Legend, Juliet and Matt's Wild Cherry. ![]() Resistant potato varieties include Defender, Cara, Sante, Cosmos, Romano and Jacqueline Lee. The following varieties are considered blight resistant, though strains of the disease vary in their virulence and even resistant varieties may not be immune. If growing conditions are always favorable to this disease then its best to use resistant varieties. This disease affects yield, but doesn’t affect storability (don’t replant these of course). The only thing you can do in these circumstances is dig the tubers 2 weeks after the tops die down and use them. In Western Washington whole beds of Tomatoes and Potatoes died almost overnight. In cool wet weather you should watch for signs of infection and remove any affected plants immediately, but it’s an indication that the plants aren’t happy with the growing conditions. Brown sunken patches appear on the tubers and may spread into the flesh causing it to rot (or provide entry for other rot causing organisms). It first manifests itself as gray-brown necrotic patches on the margins of lower leaves, but these quickly enlarge and kill the whole leaves (sometimes overnight). This fungus prefers high humidity, wet weather and mild temperatures (50 to 80 degrees F). They can also be carried on the wind and in the right conditions they can travel long distances rapidly (as happened during the Potato Famine). The spores are most often carried by soil splashed on to leaves by rain or overhead irrigation. It is called Late Blight because it prefers warmer weather than Early Blight and usually occurs later in the year (it doesn’t usually bother early crops). Though best known as a potato disease, it also affects tomatoes, peppers and eggplant. ![]() This fungus disease is notorious because it caused the Potato Famine that killed one and a half million Irish people and causing another million to emigrate.
