Pests and Diseases
The sweet pea plant does suffer from some pests, the most common being aphids. These insects suck the sap out of the plants, reducing growth. Mosaic virus is spread by greenfly, causing yellowing of leaves, distortion of new shoots, and inhibited flowering.
A pest called the pollen beetle which is small, shiny and black, eats the pollen and disfigures the flowers. Other pests include caterpillars,thrips, slugs and snails. Another problem is mildew; this is a white powdery coating that covers the leaves and slows down growth.
