Brazilian Heart Begonia Care

While they enjoy humid conditions, they don’t like “wet feet;” soggy soil can cause their roots to rot. In dry weather, supplement Mother Nature’s begonia care with a rejuvenating fine mist via the sprinkler for 15 minutes in the heat of the afternoon and sufficient bottom watering—remember, just enough to keep the soil lightly damp but not waterlogged.

fertilizing twice a month through the growing season with one of the water-soluble fertilizers like Miracle Gro, Ra-Pid Gro or Plant Marvel. During winter, it gets an occasional feeding of six drops of Schultz Instant to a quart of water. If you use a soilless mix, constant feeding is needed.

B. solananthera likes good light but needs to be protected from too much sun unless the sun in winter where you live is very weak. It thrives in the shaded greenhouse or window during summer.

This begonia grows happily in a variety of potting mixes as well as in any of the soilless mixes. As I use soil, sand, peat, dolomite, and bone meal in my potting mixes, I do not add additional fertilizer until the plant has become well establishe

Under fluorescent lights or in windows, it is best to grow B. solananthera in either plastic or clay pots placed inside decorative footed containers with a layer of gravel in the bottom. When growing plants this way, be sure to check frequently to be sure no water reaches the bottom of the pots for the roots of the plants rot if the pot is standing in water.
