Question: Azalea not blooming

I have had an azalea for about 4 years that made me a few flowers the first year and then nothing was seen again - the foliage grows a lot and looks good. I put a lot of it in order not to make it grow out of all proportion and now I put it from the earth in a pot but this year no flowers - does it need sun or partial shade? now I put it in my garden in a sunny position, before it was on the north balcony but with lots of light. Will I ever be able to see his flowers ??????


Answer: Azalea that does not bloom

Dear Laura,

azaleas are part of the same genus as rhododendrons, and are native to Asia; they are acidophilic plants, and therefore, to develop at their best they need acid soil: if you water them with water rich in limestone, at least every two or three years you will have to replace the soil in the pot with a suitable substrate for acidophilic plants, consisting mainly of peat; to prevent the leaves from turning yellow, due to their inability to absorb iron from soils unsuitable for their development, from March to September (every 12-15 days) provide fertilizer for acidophilic plants, which contains chelated iron, which is easy absorption by the roots of azaleas. This is to have a healthy plant; now we come to the flowers, the main reason why your azalea does not bloom is your regular pruning: azaleas bloom in early spring, on the branches of the previous year; this means that the flower buds are already being prepared at the end of the summer; if you prune them too often, on the one hand you go to cut off the floral buds, on the other you force the plant to always produce new vegetation, with great commitment of energies, which are subtracted from those to produce flowers: the result of an azalea that it is regularly pruned is an azalea without flowers. If your azalea shrub tends to grow a lot, you can prune it, but only after flowering; in fact, if they are not pruned, azaleas tend to remain fairly compact, and often do not need any type of pruning, other than the removal of the apex of the branches that have bloomed, so as to avoid wasting time and energy in production of seeds. In nature, azaleas are undergrowth plants, accustomed to bright partial shade, with a cool and humid climate. Not knowing where you live, I can't tell you whether it's appropriate to keep your azalea in full sun; these plants do not like scorching heat, and therefore in many regions of Italy, especially in summer, it is good that they enjoy the coolness of the partial shade, especially during the hottest hours of the day; if, on the other hand, you live in the regions of the far north of Italy, or in a mountain place, with cool nights even in the height of summer, then you can safely keep your azalea in full sun all year round. However, consider that these plants love a humid climate, and it is much more difficult to maintain high humidity in full sun in August, even if we are talking about Bolzano.
