Garden experts say the much-loved flower loses its colour and can turn brown quickly for a number of different reasons which they have listed
Those who have hydrangeas can save them from turning brown if they do these five things.
They are a much loved and hardy flower but can suddenly lose their colour and turn brown. Many gardeners don’t know the reason it’s happening, either. But experts say there are five reasons the much-loved flower loses its colour.
1. Underwatering
Watering plants keeps the garden happy. But in summer, it is vital to have a watering schedule to ensure plants are hydrated. Graham Smith MCIhort, a gardening expert from LBS Horticulture, says, “If your hydrangeas are turning brown and look limp, this can indicate that it is being underwatered. This can be just the tips of the flower petals turning brown, or the entire flowerhead in some cases.”
He suggests ensuring the soil is constantly moist but not waterlogged. Gardeners should also water their plants at the bottom of the hydrangea to assist with this.
2. Overwatering
This can also cause your plants to go brown or make them droop, He said hydration can also be just as fatal for certain plants such as hydrangeas. Anna Eklov, Director of LOV Flowers says: “While hydrangeas need regular watering, too much water can lead to root rot, which can cause the leaves and flowers to brown and wilt. To stop this, check the soil moisture level before watering and ensure that the plant has good drainage.”
3. Too much sunlight
Plants are not be happy with consistent sunlight. Although the sun is one of the main sources of life, it can cause major health issues. Graham says: “Hydrangeas may also turn brown as a result of heat stress if they are planted in a location where they are receiving full sun. Some varieties can cope with full sunlight, but others require partial or dappled shade”.
Certain hydrangea types need shade in the warmest part of the day, Instead they should be relocated to a different area. Putting mulch around the base of the plant can retain soil moisture which regulates their temperature.
4. Wong soil pH
Gardeners should not forget to test their soil pH before planting hydrangeas Garden experts say it is more crucial to a successful garden than once thought. Graham explained: “The pH level of your soil may be the reason why your hydrangeas are beginning to turn brown. Although hydrangeas can change colour depending on the pH of the soil, if the soil is too acidic or alkaline it can cause the plant to struggle to survive.”
Gardeners are advised to test the pH of the soil and choose a fertiliser which will adjust to the plant’s health. A soil tester such as Flintronic 4-in-1 Soil Tester from Amazon can accurately test soil for levels for pH, soil moisture, light exposure and soil temperature.
5. Transplanting
Moving your hydrangea from one location to another can also cause it to turn brown. This is more likely with an outdoor plant than an indoor plant. Graham says: “This can cause transplant shock which may make it turn brown. Hydrangeas are most vulnerable when moved during the peak of summer when the soil is dry, and brown leaves indicate that the hydrangea is not coping well with being moved.” If you need to rescue a plant water and fertilise it little and often and avoid moving it during periods of hot weather.
