The up-coming handbook "Orchids in the San Joaquin Valley"  complied by Richard Buchter, has been prepared primarily for the use of the members of the Central California Orchid Society.  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.

June-July in the Greenhouse

Plant growth reaches its climax during these two months.  All re-potting should be complete by now.  Clear, bright Valley days can cause quite high greenhouse temperatures, so monitor shading, ventilation and cooling.  Increased spraying/misting can result in root rot.

Cattleyas:  Re-pot summer-flowering Cattleyas immediately after flowering.

Paphiopedilum:  Sufficient shade and humidity essential now.

Cymbidium:  Provide ventilation and lots of fresh air.  Keep roots cool.

Calanthe:  Good pseudo-bulb development requires high temperatures, plenty of moisture and manuring (adding some commercial steer manure to the mix when you re-pot will generally insure good growth and usually eliminate need for additional fertilizing).  Use manure with care as too much may result in root burn.  Commercial orchid fertilizers work satisfactorily for Calanthes.

Housekeeping Tasks

1.  When re-potting, ALWAYS PREPARE YOUR LABEL FIRST (include the re-potting date on back of label).  Never work on more than one plant at a time.  Be sure each newly re-potted plant has a label.  Replace old, illegible labels.  Make every effort to ensure the spellings are correct.

2.  This may be a good time for necessary repairs.  This is also a very good time to service/repair your heating system.  If you move plants out of the greenhouse while making repairs, be sure to provide shading and humidity.

3.  Check/maintain ventilating fans and swamp cooler pads.  Check swamp cooler pads at least once a month for mineral buildup.  Replace as required for optimum cooling efficiency.

4.  Stake and tie new growth for best development.
