Tips for Success:

• Place in good light; some direct sunlight is needed.• Accurate watering – Bring plant to a slight wilt between   waterings.• Moderate fertilizer once a month. Stop fertilizer in the winter.• Keep humidity above 50% and night temperatures above   60-65ºF.• Growth cycle slows and stops for 2-3 months in the winter.   Plants can lose some leaves during this resting period.   This is normal. Continue normal watering.• Use terra cotta or clay pots.• Keep an eye out for mildew to which Rexes have some   susceptibility.
