![]() However, if plants do begin to show signs of blight infection then remove infected leaves immediately and incinerate if possible. Also, a very leafy plant can affect adequate air circulation. This will encourage more leaf growth and therefore produce more surface areas for infection. For example, don’t feed tomato plants with fertilisers that are too high in Nitrogen content. It’s always best to try and avoid creating conditions, for which Tomato Blight will thrive rather than try to deal with the problem afterwards. Tomatoes grown under glass or in polytunnels are less likely to become infected. Remove any leaves that show signs of yellowing or brown patches immediately and burn if possible. As a precaution water in the morning rather than leaving plants wet throughout night. Water plants at the base only and avoid planting tomatoes too close together. Otherwise a warm, dry and sunny position is best suited rather than partial shade. If you are planning to grow a small crop of tomatoes then containers or growbags might be a safer option. For the same reason, it’s also not advisable to grow outdoor tomatoes on ground that has been previously used to grow potatoes. If previous crops of outdoor tomatoes have suffered due to blight then it’s not advisable to plant tomatoes in the same plot as spores can over-winter in the soil. The fungal spores can be spread by the wind and carried up to 30 miles or more, which makes the disease difficult to avoid if conditions allow, such as a typical, long wet British summer. The disease is much more prevalent during long spells of warm, damp and humid weather. Affected leaves and stems will display brown spots or patches, which quickly spread and will very often give rise to areas of white fungal growth on the underside of leaves. The fungal organism can spread rapidly throughout the foliage and fruit of tomatoes, killing off leaves and causing tomatoes to rot on the plants. Tomato Blight, which is also known as potato blight or late blight is a fungal disease ( Phytophthora infestans) that can devastate outdoor tomato crops very quickly. Losetto was selected as one of the best for growing outdoors.Īverage Packet Contents : 10 seeds Only: £1.99
