WATER & HUMIDITY

Orchids need water together with CO2, light and other nutrients to possess optimal growth and blooming.
Water is present as water vapor in air and as liquid water from tap or natural sources (e.g. rain).

The humidity of air should be sufficiently high. If air humidity is too low (dry air), the orchid leaf pores (stomata) will close to prevent water loss by evaporation. Consequently, in dry air, no water vapour can be absorbed by the orchid leaves.

Different orchids require different air humidities. As a crude rule of thumb, air humidity should be higher than 70%.

If the humidity is high (higher than 80%) the air should be kept in motion by a fan to prevent stagnant wet air. Stagnant wet air may cause rot and other diseases to orchids.

Water poured on the potting material could contain dissolved fertilizers. The importance and role of fertilizers is often underestimated. A separate chapter on fertilizer mixtures is included on this web site and can be reached by clicking on: FERTILIZER

WATER & HUMIDITY NEEDS are, among others, discussed in a series of 20 interactive chapters on orchid care, present together with a photo gallery with more than 7,000 interactive full screen orchid photos, and an orchid classification system on: MöhltiMedia's Orchid cd rom.
