Azalea Flower Ontario. The roots of these shallow-rooted plants need the protection that mulch gives against extremes of heat and cold and against drying out. The deciduous Azaleas flower is produced before the foliage.
Provide well-drained humus-rich soil that is slightly acidic pH 456. Remove azaleas and rhododendrons from the plastic pot before planting. They come in many flower colors including pink red white yellow and purple.
A beautiful plant to include in a woodland garden.
Deciduous varieties flower more profusely in full sun. Blaauws Pink Azalea is bathed in stunning clusters of lightly-scented coral-pink trumpet-shaped flowers with a hot pink blotch at the ends of the branches in late spring before the leaves. A wonderful gift. City of Toronto.
