Our handbook "Orchids in the San Joaquin Valley" compiled by Richard Buchter, is tailored to growing orchids in Central California climate. It is in no way intended to take the place of the many excellent books written by authorities on the botanical peculiarities and cultural requirements of the Orchidaceae. This handbook contains information which both the new and the experienced grower may find useful. The orchid culture recommendations are offered as simple and generally applicable practices for use in the San Joaquin Valley.
The following information has been extracted from "Orchids in the San Joaquin Valley".
February in the Greenhouse
Follow January recommendations if cool, dull weather persists in the Valley. Rapid temperature changes can now occur as sunlight increases. Formation of buds is directly related to sufficient light. Very bright, sunny days towards end of month require some shading – especially for Phalaenopsis and Paphiopedilum.
CATTLEYAS Most are still at rest. Increase humidity on sunny days.
CYMBIDIUMS Provide good air movement and keep plants in bud moist. Good light required for blooms.
PAPHIOPEDILUMS All plants, even those in bud, may be repotted as required. Keep plant axils dry to prevent bud rot.
PHALAENOPSIS Even moisture and good light is essential for bud formation. Do not change position of plant once buds begin to develop!
DENDROBIUM Cool section species remain cool and dry. Warm section species are still at rest (60°-65°F and not too moist).
ODONTOGLOSSUM/ONCIDIUM ALLIANCE Still at rest.
VANDA Provide warmth and bright light for flower development.
CALANTHE Un-pot after bloom period, dust roots with fungicide and store in a cool dry place until new growth appears (3-5 weeks).
Housekeeping Tasks
1. Check all plants for ants, mealy bugs, scale and slugs/snails.
2. Prepare plants for spring show. Clean foliage, stake blooms and check plants labels. Check Sander’s registry in Society’s library for names of registered hybrids and correct parentage.
