Instructions for a Sinningia
These care instructions are written specifically for our sinningia
plants, more commonly known as florist’s gloxinia. Other growers may have different care
requirements for their plants based on how they have grown their sinningias. But if you have a Brennan’s Orchids sinningia,
these rules will help you keep it happy and robust.
Rule No. 1: Sinningia grow from tubers, so there is seasonality
to them. When the plant is actively
growing, keep it lightly moist. When the
foliage dies back, just mist the soil regularly to keep the tubers from drying
out too much. Start your normal watering
when new leaves start to show. As with
most plants, sinningias can survive a short drought, but they don’t recover
from drowning. Use tepid water when
watering. Nobody enjoys a cold
shower. Water the soil, not the
plant. Sinningias are prone to crown rot
and gray mold which happens when the leaves stay wet. Do not let the plant sit in water, it must be
Rule No. 2: Sinningias are shade plants. They have the same light requirements as an
African violet. Morning or soft late afternoon
light is best. That means an East, shaded
West, or North-facing window. By all means, avoid direct sun during the harsh
“skin cancer” hours of the day.
Rule No. 3: Regular meals during the growing season,
please. When in leaf and bloom, fertilize
every other watering. Use a fertilizer
with a balanced formula (
Rule No. 4: Your plant is potted in a peat potting mix
but any well-draining soil-less mix will be fine. Repot your sinningia when new shoots appear. Increase the pot size only if you must and
then by the smallest increment possible. Avoid deep pots; they will hold too much moisture. Moisten the mix prior to removing the plant
from the old pot. It makes it easier to
remove the plant without damage. Moisten
the new mix before planting. Pot the sinningia
so that the mix is firmly in the pot but still airy. Remember to pot the plant so that the crown
of leaves sits just above the potting mix surface.
Rule No. 5: Remove spent flowers. In particular, do not let spent blossoms drop
onto the leaves and lay there. This will
invite rot and disease. Remove old,
yellowed, or unhealthy leaves. A clean
plant is better able to remain pest and disease free. If you use anything to
cut leaves or stems, please sterilize the instrument first.
Rule No. 6: Keep the plant in its comfort zone. It is happy in the temperature range between 65 and 85 degrees. It is well suited to normal house temperatures.
