Phalaenopsis wilsonii Care
This is a cool-growing phal that requires cool evening temps and a differential between the day and night temps of at least 8C. Day temps should not exceed 28C, and avoid the heat of direct sun. The dark green leaves will likely make them easier to scorch, so acclimate new plants to bright growing areas, slowly.
I grow my phal wilsonii at a South window with with a sheer cloth knocking back about 60% of the sun’s intensity. It grows in a bright location; however my windows are well insulated so the leaf temperatures remain cool even during the hottest days. In the summer I run my air conditioner continuously to keep the house temp under 25C. In the winter the temps go down to around 16C in the nights. On especially cool winter nights (-25C OUTSIDE), our indoor temperatures near the window may go down to 12-14C.
Watering: I use pH-adjusted water (5.8pH) and flush the pots every week with 7.5pH 250ppm alkaline tap water. Though I received this plant with only 2 leaves, it has grown vigorously and done well. Water with the objective of “wet / dry cycles” on a 5-7 day cycle. The roots should be just approaching dryness as you water again; in winter let the roots dry slightly more, but keep the watering routine regular to avoid leaf drop.
