How to Grow

Although Begonia ‘Santa Cruz Sunset’ is from seed, it can be tricky for a home gardener to grow it from a seed. It should should be purchased as a starter plant and planted in full sun in a well drained soil. For best performance use a well-balanced fertilizer once or twice a month. Allow the plant to dry out slightly between waterings. The roots are very sensitive to excess moisture, so do not let them sit in water.

Troubleshooting tips:

If your soil has a pH of 6.5 or higher, it can cause the leaves to become yellow. Adding a soil amendment to lower the pH will return the leaves to a healthy looking green.

This type of begonia requires “long days” (more than 14 hours of light) to initiate buds. This means that if you take it indoors in the fall to enjoy it as a house plant, it will probably go out of bloom for most of the winter.

In areas that experience long-term extreme heat it is best to move the plant to a shadier location.

Never water plants at mid-day. The water is not absobed as well by the plant and it can cause scorching of the leaves. It is best to water early in the morning or at least 2 hours before sunset.

  1. Does anyone know how many years you can replant the tubers? Some places you buy the seed say two and some say thre years. I question if there is a limitation. I planted secon year tubers this year that are eight inches in diameter. Another question: are they a F1 or are they a variety. Here again some sellers say they are F1 and some don’t.

    • I am on the third year of planting mine and they are doing well. We’ll see if I can beat the odds and get them to go longer.

      They are an F1 hybrid. I suspect many places don’t list it and try to be ambiguous so that customers that don’t want hybrids will accidentally purchase them.

      • The original seed I purchased and grew out produced plants with quite a bit of variation in plant size, leaf size and flower size. All were good but somewhat different. Seed collected from these original plants produced even more variation. Some took longer to bloom, some were a much smaller plant and bloom and some were no different than the F1 mother plant. Not saying they were less attractive than the mother plant, just saying some were somewhat different. One mother plant will produce many, many seed. Each year I purchase more F1 seed in addition to growing out some of the F2 (?) seed collected. Needless to say I love working with his variety.
