Why is it that Hydrangeas Die?

Flowering hydrangeas (Hydrangea spp.) Create large clusters of small blooms and ornamental foliage. Hydrangeas rise in U.S. Department of Agriculture Shrub Removal prices Littleton hardiness zones 3 through 9, based on the variety. Keeping the shrubs healthy requires proper analysis of any problems as soon as they appear so that they don’t destroy the shrubs.

Cultural Factors

The wrong growing place or improper care can quickly cause a hydrangea to fall or die. Hydrangeas require moist, rich soil. Drought or sandy planting Boise websites that drain too fast lead to a water-stressed Stump Removal cheap Bakersfield which loses foliage and finally dies. Wet, soggy soil causes the roots to drown, while also preventing them from accessing necessary nutrients in the soil. Most cultural problems have been avoidable by planting Boise hydrangeas in areas having light afternoon shade and also in well-drained soil amended with compost or aged manure to present organic matter.

Pythium Root Rot

Pythium root rot may soften both mature and newly planted hydrangeas, and it may lead to Stump Removal front of house Fort Lauderdale death when it isn’t treated. Pythium root rot is the most dangerous to young plants and those grown in too wet soil. Terminal branches die back first, followed by the rest of the hydrangea. Keeping the soil moist but not wet minimizes Pythium root rot problems.

Mushroom Rot

Armillaria root rot is also known as mushroom rot because it often produces clusters of white mushrooms around the foundation of an affected hydrangea. The hydrangea shoots wilt and the entire Shrub Removal front of house Phoenix, AZ may die in a few weeks. The fungus invades the cambial tissue in the hydrangea trunks. There are no treatments for mushroom rot, therefore prevention is necessary. Avoid planting Flagstaff hydrangeas in locations where other plants have already experienced the illness and remove old Tree Service companies Fort Lauderdale roots from planting Redding websites before planting Miami. Oakleaf hydrangeas (Hydrangea quercifolia), which develop in USDA zones 5 through 9, are more vulnerable to armillaria root rot than other hydrangea types.

Fungal Rust

Red, orange or yellow patches on leaves and declining foliage can indicate a fungal rust infection. The spots are caused by fungal sporesthat eventually spread and cause the entire leaf to discolor and finally drop. Stems and leaves can also develop poorly or become deformed, so even new development is affected. Badly infected hydrangeas eventually fall and perish. Although fungicides have some affect, they are not advised to be used in many landscapes. Maintaining overhead watering and removing dead and dropped foliage in the beds provides a much better control technique. Trim off infected branches instantly, cutting them back to your nearest wood. Wipe shears using a cloth soaked in rubbing alcohol after each cut to avoid the spread of the spores.

Caterpillar Damage

Foliage feeding caterpillars, such as the greenhouse leaftier, devour entire hydrangea leafs. They leave behind a skeletonized dead leaf, which can’t support the Shrub Removal cost Phoenix, AZ. Large populations can defoliate the hydrangea into the point where it could no longer support itself, so the Stump Removal price Littleton dies. Removing the insects by hand and trimming out badly infested divisions with disinfected shears keeps populations in check so significant damage doesn’t happen. Avoid overfertilization and water sufficiently so the hydrangea doesn’t suffer stress.
