The Orchid Pseudobulbs

The pseudobulb, a green, banana-like object at the base of the leaves, is a very interesting and vital part of the orchid plant. In it the food and moisture obtained from the air and water (the orchid's sources of nourishment) are stored.

This fleshy plant part is a sort of gauge of the plant's health and wellbeing. If wrinkled and dry, more moisture is needed. If yellow, the plant needs more light or may be getting too much water. If it rots, much less water is the prescription. If fat and full and green, all is well. One soon learns to strike a happy medium.

The few minutes daily care that orchids require is mostly a matter of watering. Those grown loose in the living-room should be submerged, pot and all, in a pail of room-temperature water for half an hour a week. The plant tops should be sprayed a few times a day.

Orchids grown in a case should get thorough soaking once a week till water runs out the bottom of the pot. Leaves should be syringed daily. The chemicals in most city reservoirs aren't fatal to orchids but neither are they beneficial. We use rain water collected from one of our house gutters. In winter we use melted snow stored indoors till it is room temperature.

The reason why orchids are so dependent on top spraying and humidity for their general health is because most kinds are incapable of taking in adequate amounts of water through their roots alone.

They absorb additional quantities through their leaves. In a sense, they have amphibious instincts. Their roots need air as well as moisture and their tops want water as well as air.

Grow-pause-flower-rest is the annual growing cycle of the orchid. When the plant is growing actively it needs more water. When its new growth is complete, the orchid must make a decision.

If the plant is kept warm and wet, it makes more fresh greenery. But if at this point it is given less water, its urge for reproduction is quickened and the decision is made in favor of a flower spike.

When a new plant is bought it is usually properly potted. It needn't be disturbed for a year or longer. If you are a gardener, it is a must to know when to repot a plant. Three ways to tell when an orchid needs repotting are: when the potting media rots or disappears; when the plant looks sick (due, perhaps, to inadequate drainage) ; when it outgrows its pot.

Orchids have a cheery habit of sprawling new growth right across the pot from one side to the other. When it dangles new, pale green roots over the edge of the rim, it's time to repot it.
