What do you do when hydrangea leaves turn brown?
Thoroughly flush the hydrangea soil with water whether it is in a pot or in the ground. Most of the salts should be removed by this. Do not water the hydrangea for a day or two until the soil is dry. After that, you can water it as you would any other plant.
Why are my hydrangea leaves turning brown on the edges?
Symptoms such as burning on the leaf margins, leaf tip dieback and increased susceptibility to pests can be caused by excessive fertilizer or pesticide use. The health of the plant can be affected by pesticide drift. Hydrangeas are susceptible to a number of diseases, including fungal, bacterial and parasitic diseases. If you suspect you have an infestation, contact your local Extension office for more information.
Do hydrangeas like sun or shade?
If they’re in the afternoon sun, they don’t do as well as morning sun. It’s ideal to have partial shade in the later parts of the day. If you live in an area with a lot of shade, you may want to consider using a shade cloth to protect your plants from the sun’s rays. You can buy these at your local garden center or online.
What is wrong with my hydrangea leaves?
Leaf spotting on hydrangea is mostly caused by the fungus Cercospora and affects most of this family of plants. It is common during the summer and fall. Plants are usually affected by the disease a month or two before the leaves appear. Symptoms of leaf spotting include yellowing of the leaf surface, discoloration, loss of leaves, and a change in leaf color.
Leaf spotting can occur on both the upper and lower leaves of a plant. In some cases, the spots can be so small that they are difficult to see with the naked eye. Other times, spots may be large enough to be seen with a magnifying glass. If you notice spots on your plants, you should contact your local Extension office for assistance.
Is my hydrangea getting too much sun?
In the heat of the day, hydrasis do not do well. It is possible to protect hydrangeas from the effects of too much sun in the afternoon. Allow your flowers to have at least 3 hours of sun each day. Too much afternoon sun can cause the leaves to turn yellow and the flowers to wilt.
