Cold temperatures lead to bottom leaf yellowing, slow growth, basal stem and root rots. Avoid over-watering the young transplants, especially in large patio pots and baskets. Apply a preventative fungicide drench to prevent fungal root diseases. Scout and treat for thrips.

HB | 4 ppp | 10–11 weeks 2 gal. HB | 5 ppp | 10–11 weeks Tech Tips: Mezoo Dorotheanthus is a trailing succulent-type vine that makes beautiful baskets and combo plantings. It is a relatively slow starter and is best grown warm to get it established and growing. Under high light, it will develop small colorful red flowers that add character to the plant. This is a very tough plant that grows and performs under a range of environmental conditions.
