Drought damage becomes a problem when there has been insufficient rainfall or when the soil cannot hold enough water. Drought is typically associated with other factors, such as low humidity and wind, or hot weather conditions. During so, the plant will continue to lose water from its pores, but won't be able to replace it within enough time; resulting in wilting. In reverse, another type of drought affects the plant slightly differently. Physiological drought involves hot, dry winds which damage the plant above ground. Frost can also cause the same problems; where both scenarios prevent the plant from taking up sufficient water quickly enough.

Symptoms

Dulling of foliage
Wilting
Leaves and roots turn 'tough' and begin to brown.
Plants begin to look unattractive or die.
Leaves become 'scorched' during long periods of dry air.
Fruits fail develop beyond a few millimetres in diameter.
Early shedding of buds and flowers when indoors or in glasshouses.

Biological treatment

If you are experiencing drought, it's advised to water plants regularly and lightly. Do not overwater plants. Take particular care of plants during fruiting and flowering. Be careful when growing crops from bags of soil. The moisture of these should be monitored regularly. Apply mulches to patches of land with shallow earth or those which don't hold onto water well. Indoors and in glasshouses, spritzing water onto plants can help to increase the overall humidity and can assist pollination. This is best done during the morning or evening, on the flowers and fruits.
