Begonia On Top™ varieties showcase many blooms over a long season on durable, compact plants. The On Top™ series tend to tolerate heat and sunlight moreso than other begonias. This collection is often encouraged to be sold at a premium retail price, resulting in a faster market turnover.
Begonias require well drained soil and consistent watering. They do best in dappled sun locations but will also tolerate full shade. Feed just after transplanting and then once weekly for best results. No need to deadhead spent blooms. Begonias are highly susceptible to powdery mildew. To prevent it refrain from overhead watering to help reduce relative humidity. If you find powdery mildew be sure to remove the infected parts of the plants as soon as possible.
