Azalea leaves turning yellow

Azaleas set their leaf buds in the fall…and the emergence of these buds prompts molting. Having random yellow leaves scattered throughout your azaleas is normal…these leaves are simply molting. There's nothing you need to do or worry about. Just wait for new growth in the spring.

What does an overwatered azalea look like?

The fungus Phytophthora occurs in soggy soils and is responsible for a significant percentage of azalea casualties. The plant first exhibits poor vigor, then begins to look dry, leaves turn brownish-green and there is no new growth.

Do azalea leaves turn yellow in the winter?

Many times from the late fall through winter, you may notice azaleas with reddish or purple foliage, yellow foliage, spotted foliage and just overall "poor-looking" growth.

How often should you water azaleas?

Watering: Water your azalea up to twice a week. It likes to drink, but if the soil gets too waterlogged – even for just an hour and a half – your azalea's roots will die. Also, never water azaleas from above.

Why are my azalea leaves turning yellow and dropping?

Typically, there's sufficient iron naturally occurring in the soil. When the soil's pH is high, the plant can't take up the iron and the formation of chlorophyll slows, and leaves turn yellow. This first shows up with yellowing between the veins of the new leaves and is called "interveinal chlorosis."

How do you rejuvenate azaleas?

When rejuvenating an azalea or rhododendron, fertilize the year before to prepare the plant and then fertilize again in spring (end of April) after the hard pruning to stimulate growth. For smaller azaleas, use bypass pruners to make the cuts. For larger jobs, you may need a folding saw or a pair of loppers.

What is the best time of day to water azaleas?

The best time to water azalea is in the morning so that the leaves have time to dry before evening. Water the soil and not the leaves to discourage fungal diseases. Use drip irrigation if possible. Azaleas do not need watering during the winter months.

How hot is too hot for azaleas?

Temperature: Different azaleas can withstand various extreme climates. White azaleas cannot withstand temperatures that reach above 80ºF, as their blossoms will wither and fall. On the other end, azaleas from the Northern Light series can withstand temperatures as low as -20ºF.

What does overwatering vs Underwatering look like?

Browning edges: Another symptom that can go both ways. Determine which by feeling the leaf showing browning: if it feels crispy and light, it is underwatered. If it feels soft and limp, it is overwatered. Yellowing leaves: Usually accompanied by new growth falling, yellow leaves are an indication of overwatering.

Should azaleas be in direct sunlight?

Azaleas do well in full sun or part shade (about four hours of sun). Planted in full sun, azaleas will be more compact and floriferous. When planted in part shade, they will stretch toward the sunlight and form a more graceful habit; flowers will not be as plentiful but will last longer.

Can azaleas get too much sun?

If the leaves of your azaleas have round, brown spots on the edges and tips and the blooms are fading quickly, they're getting too much sun. If you're growing them in containers, move them to a shadier area.

Why do my azaleas look sick?

Nutrient deficiencies are another common factor with azaleas. Plants may exhibit discoloration with fewer or undersized foliage and flowers. Nitrogen and iron are the most commonly seen deficiencies in azaleas. Inappropriate watering can cause foliage to wilt, discolor, and drop.

How long can azaleas go without water?

Watering Azaleas They're shallow-rooted plants and need to be kept uniformly moist so the roots don't dry out, but azaleas can't tolerate soggy soil. Water established plants with about 3/4 to 1 inch of water every 10 to 14 days during dry periods, moistening the soil to a depth of 10 to 12 inches.

What time of year do you fertilize azaleas?

The best time to fertilize is right after spring bloom. This spring application may be all you need, but if you live in an area with a lot of rainfall and a long growing season, you may want to make a second application in mid to late summer, making sure not to fertilize after August 1st.

Is it possible to overwater azaleas?

Garden azaleas only require extra water during long dry spells. With indoor azaleas, you should check the soil every so often. If it's too dry, give the plant a little water. Never overwater an azalea, as it is a plant that loves moderation.

What does a dying azalea look like?

Symptoms include leaves that go from pale green to yellow to brown, prematurely falling leaves, and dieback. Unless the plant was exceptionally healthy before contracting the disease, you might find that your azalea bushes are dying within two or three weeks.

Will Epsom salt help azaleas bloom?

Epsom salt can improve the blooms of flowering and green shrubs, especially evergreens, azaleas and rhododendrons. Work in one tablespoon of Ultra Epsom Salt per nine square feet of bush into the soil, over the root zone, which allows the shrubs to absorb the nutritional benefits.

How do I make my azalea soil acidic?

Home gardeners can lower their soil pH by adding sphagnum peat moss to the soil. (The pH of sphagnum peat moss generally ranges from 3.0 to 4.5.) When planting azaleas and rhododendrons, dig a wide, shallow hole. Backfill with a mixture that is half soil and half moistened sphagnum peat moss.

Do coffee grounds help azaleas?

Feed Your Acid-Loving Plants Place coffee grounds around the soil of your acid-loving plants such as azaleas, hydrangeas, lilies, roses, rhododendrons, holly, gardenias and many others. Coffee grounds increase acidity and nutrients in the soil. This is our favorite reason to use coffee grounds in your garden.

How do I know if my azalea is dying?

Look for life by testing the stems for signs of green. Take your fingernail and lightly scrape a stem. If you see green where you scraped the stem the azalea is still alive. If at the first scrape you don't find green on the stem go further down the stem, scraping every 2-inches (5cm) until you find green.
