Melons are heat-loving plants but do not tolerate excess moisture, which causes fruit rotting and sick leaves. Melons are susceptible to mildew and viruses like all plants in the pumpkin family. Varieties with resistance or tolerance to diseases are available. Therefore, outdoor cultivation is only possible in favourable locations. In unfavourable growing conditions and for season extension, melons are produced under foil or glass. In sheltered cultivation, much higher yields are achieved compared to outdoor cultivation.
Due to their shallow root system, melons need a regular water supply. The shoots are often cut for better fruition.
