How to Care for Your Azaleas Indoors

Azaleas in the indoor garden can bring an abundance of vibrant flowers for your home in the spring and require only the bright indirect light as well as cool temperatures.

The care of indoor azaleas is fairly easy, but there are some things you should be aware of to ensure that your plant is well-maintained…

Read on to discover the best ways to care for indoor azaleas, and how to avoid the most frequent issues…

Soil For Indoor Azalea

Indoor azaleas require a pot soil with these characteristics:

  • A porous, well-draining structure that allows excess water to be drained away from the roots and to allow the root to breathe.
  • Soil that retains moisture so the roots are able to draw on the moisture at any time they require.
  • Acid soil that has an acidic pH of 6 to 6.4
  • Soil that has an organically high content is ideal to provide nutrients

Indoor azaleas can be grown using commercially available potting mixes in gardens and on the internet that are crucially within the ideal pH range for azaleas. Azaleas won’t thrive in soils with pH levels that are neutral or alkaline because they will not be able to absorb nutrients, so specially formulated pots are a great option to make sure the soil is at the correct amount of acidity for Azaleas.

You can also make your own potting mix using ingredients like leaf mould, pine needles (oak as well as beech leaves are great) Peat moss and garden soil.

All of these substances are acidic and help to create an aerated soil that retains moisture, but also lets excess water be able to drain away, to ensure that the soil doesn’t get boggy, which can lead to conditions that cause root decay.

A uniform mix of these ingredients can provide the proper structure, acidity, and the balance of nutrients needed by indoor Azleas. Learn from my article how to make the ideal potting mix for Azaleas.

I would suggest a layer of gravel on the base of the pot to ensure that the drainage holes are at the bottom free of soil that has been compacted to allow water to flow easily, which can help stop the fungal disease root decay.


Watering Indoors

Azaleas are rooted in shallow ways that require soil with moisture, so they are usually among the very first plant species in your house or garden to show signs of drought during the most extreme times of the year.

The most important thing to do to keep indoor azaleas in good health is to ensure that the plant is watered by giving it a good soak every day to ensure that the soil remains damp.

In dry or hot environments in your home, you’ll need to water your azaleas more often, usually up to two or 3 times per week, with occasionally a mist to boost the humidity.

In homes that are cooler and during cooler seasons, the azalea might only require irrigation once a week to ensure that the soil’s moisture remains in the proper balance.

Indoor azaleas that are of the variety of indica (common name evergreen azaleas) is the most popular variety of azaleas that are sold in florists and garden centers) only require indirect lighting that will help control the soil’s moisture. If the azaleas are in direct sunlight, you will require watering your indoor plant more often.

Avoiding over-watering by using a high-quality indoor azalea potting mix an area of gravel on the bottom of the pot, and the pot has drainage holes in the bottom.

Drought is always a greater danger for indoor azaleas. However, when they appear like it’s wilting even after regular watering, the issue could be root rot. Check out my guide on issues with azaleas that are in pots for more details.

Important Note: If you can, water you indoor Azaleas with rainwater. Azaleas require acidic soil in order for the roots to absorb nutrients. They prefer rainwater because it is slightly acidic, whereas tap water is usually neutral or even alkaline , which could be a deterrent of your Azalea.

It is essential to avoid drought and therefore watering every now and then using tap water won’t cause harm, but using tap water to water your lawn for long periods of time is not recommended.

Fertilizing Indoor Azaleas

The importance of fertilizing indoor azaleas due to a variety of reasons:

  • The plants that are potted naturally are less able to absorb nutrients, therefore the soil needs to be enriched each year.
  • Fertilizing Azaleas can help ensure they are healthy and disease-resistant.
  • Fertilizing (in the spring) assists in supporting the growth of new plants and flowers.

The most effective time to fertilize azaleas is during the spring (March/April) in order to encourage the growth of new plants and to encourage flowers. Don’t fertilize later in the growing season since this can encourage growth, but at the expense of flowers.

It is essential to choose an fertilizer specifically designed specifically for Azaleas (such as this miraculous grow fertilizer) because it has been designed to provide the right amount of nutrients needed by azaleas. Azaleas’ tender roots and leaves can be very vulnerable to fertilizers that are too strong for them.

Special fertilisers (also appropriate for the rhododendrons as well as camellias) can aid in the reduction of acidity in soil, ensuring that the proper soil pH is maintained over time without much effort. This means that the roots of azaleas can absorb all nutrients needed to stay healthy and last for a long time.

Choosing the Right Pots or Containers

The soil of indoor azaleas must retain moisture. They also have a pores that allow the excess moisture to flow away from the roots , thereby preventing root decay.

So, the pots used for indoor Azales require drainage holes at the base in order to allow water to drain away so that the soil doesn’t become spongy and increase the chance of fungal diseases. The layer of grit on the base of the pot could aid in keeping the drainage holes free of the soil that has become compacted, which could stop water from flowing out.

Select a size of pot that will accommodate the root ball in a comfortable manner, but especially indoors, azaleas don’t like their roots becoming stuck in the pot as long as they get sufficient water and an application of fertilizer in Spring.

Room Temperature and Sunlight

Indoor Azleas (azalea Idicum) require a relatively cool temperatures between 13-16degC (55-61degF) in the winter months and temperatures that can reach up to 22 degrees Celsius (71 degF) during summer.

Keep them away from direct sunlight and it is essential to shield the plant from draughts, heating, air conditioning radiators, forced air and heating.

A hallway, porch or any room that is cool and has sufficient light is ideal. The direct sunlight can accelerate the rate at which soil of the azalea gets dry that causes wilting leaves blooms, drooping flowers and stunted growth.

Azalea idcum can also have delicate leaves (as is typical of the azaleas and rhododendrons) and is susceptible to sun-induced damage if exposed to excessive sunlight..

Too too much shade in a space will hinder flowering, so try to use bright indirect light to get the best results.

Common Problems

Leaf drop

The most frequent issue for indoor azaleas is leaf fall. It is usually an indication of stress in homes with an extremely high temperature or changing temperatures from day to night. This is especially common during winter when the heater is on to keep warm during the cold winter night.

Place the azaleas in an area in which the temperature is more stable and you will not experience any issues. The azalea will be able to recover before the next season.

There are reasons for leaf fall that you can find the solution to within my post what is causing my azaleas in my home falling off.

Wilting Leaves and Flowers

The wilting of leaves typically result from drought , but it is also possible because the soil has become boggy due to the pot for azaleas does not have enough drainage at its base.

Drought poses a threat to indoor azaleas, and the first indications of stress are the wilting of leaves and flowers, with leaves curled up. It is easy to treat ample watering, and the plant can be able to recover within 24 hours.

Remember that azaleas need the soil to be moist , so make sure to water your plant as often as is needed to keep the soil moist.

If the issue is root decay (wilting appearance, with spots of brown on leaves) then you need to plant the azalea in fresh well-draining compost. Also, make sure that the pot is equipped with drainage holes at the base.

Indoor azaleas may not get over root rot, but cutting off the affected roots (yellow that has a decayed look) using a sterilized pair of pruners can help.

Yellow Leaves

The yellowing of leaves is usually an indication of stress due to:

  • Conditions of the soil that aren’t within the optimal pH range (pH 4 – 6)
  • Insufficient fertilizer application during the spring time

It is essential to plant azaleas in a prepared acidic compost, which can be found at stores or on the internet or you can make it yourself using compost, peat moss and leaves mould mixture.

Rainwater is a good source of water. apply a fertilizer designed for plants that require acidic conditions . the azalea will be able to recover, though it could require some time.

Since the availability of nutrients is restricted in pots it is essential to fertilize in spring. is essential to supply the azalea with the proper amount of nutrients needed to ensure the plant’s health.

Yellow leaves may turn green within two weeks following the application of fertiliser. For more details, read my article on ways to help Azaleas that have green leaves that are yellow.
