Sowing: in a bucket of fine sowing compost in March/April on a warm layer (25°C constant) indoors or in a heated greenhouse. Cover the seeds with a few mm of seed compost then tamp down. Place your buckets near a window. 
Water the surface lightly if the soil dries out. 

Transplanting young plants measuring 15 cm in the ground after the risk of frost has disappeared,  in a fresh, deep and humus-rich soil with a warm and sunny exposure at 50 cm in all directions. 
Hoe, weed and ridge the eggplant plants. Water the feet regularly.  Mulch. 

Mildew: will cause gray-green spots to appear on the leaves, while the underside will be covered with white felt. 
In preventive action, hoeing and watering with nettle manure and horsetail tea. Before the plant flowers, or as soon as the first symptoms appear, it is also possible to treat with Bordeaux mixture.

Red spiders: the leaves are first covered with gray spots before taking on a tanned appearance, then drying out and falling. They weave webs on the leaves. 
Cut the aerial parts and burn them. Treatment by spraying black soap or nettle manure can then be considered. A plant insecticide (Anti-Aphids based on Pyrethrum) can also be used.

Colorado potato beetles: pick them up by hand. 

Aphids: attack leaves, buds and stems. 
Spray a black soap-based solution or nettle manure. A biological plant insecticide, such as a Pyrethrum-based Anti-Aphids, can be used in the event of a major attack.
