Do gloxinia plants come back every year?
Today’s gloxinias are hybrids bred to quickly produce a large number of blossoms. These gloxinias produce an outstanding display for about two months, but once the flowers fade, the plant rarely comes back because it invests all its energy into flowers rather than sturdy roots.
Are gloxinia easy to grow?
Gloxinias are relatively easy to grow from seed, but the plants take five to seven months from seed to begin to bloom. The really great news is that once you have a mature gloxinia plant, it can live for years and will produce more flowers in succeeding years.
How do you get gloxinia to rebloom?
If your gloxinia flowers dried up too early and the smaller side buds never bloomed, it might be due to cold air (this plant likes 75-degree days and 65-degree nights) or how it was watered (room-temperature water should be applied to the soil only; never let the plant dry out until you want it to go dormant).
Can you plant gloxinia outside?
Grown from tubers, gloxinias are typically planted outdoors in spring after the danger of frost has safely passed. In zones where the cultivar is not hardy, you need to store tubers for winter or grow gloxinia as potted plants.
What to do with gloxinia after flowering?
Gloxinias need to rest after blooming. To induce dormancy, gradually cut back on watering. When the foliage dies back, trim it off and place the pot in a cool (55 to 60 degree Fahrenheit), dark location. Let the gloxinia tuber rest for 2 to 3 months.
How do you overwinter gloxinia?
Overwinter tuber-grown gloxinias. Plants grown from tubers can be stored in a cool, dry place for the winter and made to bloom the following year. After flowering, water lightly until the leaves die down. Then, allow the soil to dry out and overwinter the tuber in its pot.
Does gloxinia go dormant?
Gloxinias require a fall dormant period for the tuberous roots to rest and recover from the previous bloom season. The plants can resume new growth and produce lush flowers again after they wake from their dormant state.
How do you fertilize gloxinia?
Gloxinias require moderate fertilization. Use Peat-Lite fertilizers such as 15-16-17 or 20-10-20 alternated with calcium nitrate-based fertilizers (15-0-15 or 17-5-17). Avoid high ammonia-type fertilizers such as 20-20-20 and MagAmp. Use 250 to 350 ppm nitrogen every second or third watering.
