The soil suitable for potted azaleas
Azalea is a plantacidophilic. For hiscultivation(in pots or in the garden) needs a specific soil with a pH lower than 6.5.
When we water the plant withtap water, we introduce limestone into the soil: limestone raises the pH of the soil, so theazaleabegins to suffer.
The best way toirrigate the azaleais to exploit rainwater. Alternatively, transfer the tap water into a basin to be done restat least one night. To maintain the correct acidity of the soil, add a tablespoon of white vinegar for every 10 liters of tap water used.

How to water azaleas
In the previous paragraph we saw the relationship betweenirrigation water and soil acidity. In this section we will see how to water potted azaleas and how to manage the humidity necessary to make the plant thrive.
When and how often to water the azalea?Potted azalea must be watered thoroughly and daily. It is necessary to see the water come out of the saucer which must then be regularly emptied. For proper hydration, in addition to irrigating the soil, it will also be necessary to spray the aerial area so as to saturate the area around the canopy with moisture. If the air is very dry indoors, it is recommended to grow moreazaleasarranging a pot next to the other, sharing a single saucer for several plants. The common saucer must always be full of wet expanded clay: the expanded clay gradually releases moisture to the plants.
Where to grow azaleas indoors
Azalea cannot be grown everywhere! It is necessary to choose the right place. As I explained in the articleIndoor plants and light, the right exposure is required. In addition to light, for the most sensitive plants it will be necessary to consider drafts, thermal shocks and the presence of air currents. L'azaleait is a very sensitive plant.
Place it in a bright and cool place. Away from drafts of cold air (that means, that in full winter you should avoid opening the window adjacent to the sill where the le are potted azaleas) and from situations that can cause thermal shocks.
If you have the opportunity, move the plants to a cooler place at night, such as the porch or stair landing. In winter, during the night, the temperature must be cooler than during the day but it must never drop below 5 ° C.

Repotting the azaleas
Therepottingit is a necessary operation, especially if you have recently purchased the plant.When to repot azaleas?After withering.
You immediately understand when the right time has come to repot the azalea. Observe the plant: if the pot is small and it becomes difficult to water the plant correctly, you can do therepotting. You can repot theazaleaafter complete withering. Choose a new pot that is at least 2-3 cm larger than the previous one. Also in this case, remember to choose a specific soil for acidophilic plants.
Before repotting, cover the drain hole with a pebble and arrange a layer of expanded clay on the bottom. Repot the plant and fill with the new soil, taking care to leave the collar of the plant uncovered and irrigate.
Fertilize potted azaleas
Fertilize thepotted azaleas with a liquid fertilizer for flowering plants. Administer the fertilizer every 10 days starting from spring, following the doses indicated on the label. If you already have a slow release fertilizer at home, you can use it, as long as it has a good ratio between the amount of potassium, phosphorus and nitrogen.
Universal fertilizers, fertilizers for flowering plants or fertilizers too rich in nitrogen are not good!
Choose acidophilic plant fertilizers with an NPK (nitrogen, phosphorus, potassium) 7-3-6and possibly enriched with iron which prevents chlorosis or other diseases that can cause yellowing of the leaves associated with irrigation with tap water.
Fertilizers of this kind are easy to find, on Amazon, a fertilizer for azaleas (and for acidophilic plants) can be bought at a price of 11.40 euros with shipping costs included in the price. For all information and to get an idea of the indicated product, we refer you to the official amazon page: fertilizer for acidophilic plants.
