Orchid of the Week: Blc. Lawless Walkiire ‘The Ultimate’ AM/AOS

This is one of those orchids that you have to see in person to appreciate.  The richness of color and the contrast of the venation in the lip are just breathtaking!  I was at the judging when this particular cultivar was awarded, & I can tell you it deserved its award.  It is a strong grower and flowers twice per year.  This Cattleya clone is commercially available so anyone with a few dollars in their pocket can have one of their very own.  To learn more about orchids and orchid growing contact the American Orchid Society.

Required Light:  In the greenhouse I use 50% shade cloth and have it in a spot where it gets mostly morning and afternoon sun but not Midday.  Under artificial lights like our T5 fluorescents I recommend it be 8” underneath at least two 4 foot T5 bulbs.

Temperature: This orchid prefers night-time temperatures to be between 55° F – 65° F.  Daytime temperatures can easily reach the low 90’s without a problem.

Humidity: Best kept at 60% RH or higher.

Required Watering: Depending on environmental factors, once or twice a week under normal conditions.  More waterings are generally necessary when it is hotter in the growing environment.

Fertilizer: Should be applied at ½ to1/4 strength weekly.  I prefer to use the Grow More brand of fertilizers.

Potting: Should be done annually as you see new roots starting to emerge from the newest pseudoblulb(s.)  I use a mixture of 4 parts coconut husk chips, 2 parts #4 Perlite, and 1 part Hydroton.  Also I like clay pots as they will dry out a bit faster keeping the roots from staying too wet.
