About this deal

Unless your soil is highly organic, it’s recommended to mix your bed or planting infill with some compost or other organic material. This can be all the fertilizer your Azaleas need, especially if you mulch around them every year. It can also be helpful to add mycorrhizal fungi, which will help your Azaleas’ roots to absorb nutrients from the soil. Always deal with these problems organically to keep yourself and the environment and surrounding wildlife safe. Houseplant Azaleas will also benefit from an ericaceous mulch on the top of the container each spring, or from completely repotting in the spring with a new, fertile growing medium if the growth seems poor or you are dealing with an Azalea forced to flower in winter.

Phosphorus: A phosphorus deficiency can be hard to detect. You may only notice fewer flowers or that the flowers are a paler color than usual. If the phosphorus deficiency is severe, the leaves may also change color, become darker green than normal, and turn reddish- or purplish-brown before falling off. Smaller than normal leaves and leaf tip burn can also be signs of phosphorus deficiency. Azaleas growing in containers outside will benefit from the addition or replenishment of an acidic mulch of conifer bark chippings or leaf mould each spring. Lightly scrape the bark for two inches above the cut end with a sharp knife – just enough to remove the outer bark in a few spots. Insert the lower third of each stem into a small container filled with a moist rooting medium, such as a combination of one-third compost, one-third peat moss or vermiculite, and one-third sand.The only way to ensure a clone of the parent plant is to propagate vegetatively, via stem cuttings or stem layering.

When feeding your Azaleas, I don’t recommend you use all-purpose fertilizers. Instead, choose a fertilizer that is designed for acid-loving plants or specifically for Azaleas. Alternatively, if you are correcting a specific nutritional deficiency, choose a fertilizer that adds only that particular nutrient to the soil. Azaleas are fairly easy, low maintenance shrubs that provide striking spring color. Choose the right species and varieties for your garden, and you will enjoy these pretty plants for years to come with little effort. Related: How much fertilizer to use is generally based on nitrogen for NPK fertilizers. The general recommendation is one pound of nitrogen per thousand square feet, or up to two pounds if you’re using a slow-release fertilizer.Mulch yearly to keep the soil acidic but don’t bury the stem, I have seen azaleas die because the gardener buried the stem. Azaleas have shallow roots and require well-drained soil. If your garden is poorly drained, consider planting azaleas in containers or a raised bed. They thrive in low pH, or more acidic, conditions. If you have high pH, or more alkaline soil, you’ll need to amend your growing area. Aluminum sulfate, sulfur, coffee grounds, and pine needles are good for this. Peat moss used to be recommended, but due to environmental concerns it is no longer a good option. Many arborists collect wood chips as a by-product of their work and often they are only too happy to let you have some if you ask,” shares Colin Skelly, Master Horticulturist. It’s an easy, inexpensive and organic way to support your garden. Rather than throw out kitchen or yard waste, you can save these materials that are rich in nitrogen and carbon to create an organic supplement that will nourish your soil and improve plant growth. We’ll explain how it works. What can I compost?
