Branches of flowering quince can be cut in late winter and forced to bloom out of season indoors. Their flowers are red to orange and will bloom about four weeks after taking the cuttings. Display them in a vase or add them to flower arrangements for a touch of spring on a cold winter's day. The flowers should last one to two weeks after they open.
Cut branches of quince in late winter to force for flowering indoors. The trees must have already been exposed to at least eight weeks of temperatures below 40 degrees Fahrenheit in order to come into bloom indoors. Make the cuttings about 12 to 24 inches long. Select branches that contain mostly flower buds, rather than leaf buds. Flower buds of quince are usually larger and rounder than leaf buds. If in doubt which is which, slice one open with a sharp knife. Inside you will find either tiny flower petals or a tiny leaf.
Cut an “X” in the flat, cut end of each branch to help it more easily take up water.
Soak entire branches overnight, completely submerged in the bathtub or a large container. This overnight soaking will help the flower buds re-hydrate and break dormancy more quickly.
Place the branches upright in a deep container, submerging at least half their length with cool water.
Set the container in a cool place, below 65 degrees Fahrenheit, and preferably closer to 60 degrees Fahrenheit. Keep them out of direct sunlight, but provide them with bright, indirect light. Mist daily or run a humidifier near them. The dry indoor air can cause the buds to drop off without opening. Check the water level daily and replenish as needed.
Move the branches to their display area or use in arrangements when the buds begin to show color, in about four weeks. Keep them in bright, indirect light but out of direct sunlight.
