Why do hydrangea buds turn yellow?

1. Missing Elements

In March of each year, when hydrangeas begin to sprout, it is normal for new leaves to turn yellow if they are grown in a greenhouse. If they remain yellow after a period of observation, you can consider supplementing them with iron and magnesium.

2. High temperature exposure

If the edges of the old leaves of Hydrangea Endless Summer begin to die, it should be affected by the temperature. If the temperature exceeds 30 degrees, the leaves will become scorched.

3. Change the leaves

The maintenance time is long, and when the season changes, the old branches and leaves will turn yellow, die and fall off. This is normal, just like other ordinary plants. Just prune the dead branches and leaves regularly.

Fat Injury

Although the endless summer flowering period can last until early autumn, it is necessary to apply fertilizer in small amounts frequently in summer, and even stop fertilizing in hot weather. Water frequently and do not let the soil in the pot dry out.

Sunburn

Hydrangeas are afraid of the sun, so they should be placed next to other plants to block the summer sun. On hot summer days, if there are no other large plants to shade them, you can use a 30-60 pin shade net. The sun in other seasons is relatively mild, so it is okay to expose it to the sun all day.

ventilation

Ventilation is the minimum requirement for plant maintenance, which is more important than fertilizing and watering. Try to create an open-air environment without too much obstruction around.

Diseases

Dead leaves can also be caused by pathogens, which can be treated by spraying with mancozeb mixed with water.

Are hydrangeas poisonous when kept indoors?

The sap of hydrangeas, including Endless Summer, is indeed poisonous. If you are allergic to pollen, do not plant them. But as long as you don't pinch them off or touch them on purpose, there will be no problem. It's okay to just smell the flowers. I pinch branches and take cuttings directly by hand every spring, and it's fine. I don't feel any discomfort after the operation.
