When hydrangea are exposed to too much sunshine , it can negatively impact their growth and ability to acquire blooms . The intense heat and sunlight can be too harsh for these plant , causing them to struggle and potentially wilt . The leaves may become scorched or show signs of tan , turn brownish and crispy .
One of the main consequence of too much sun is a decrease in bloom of youth production . hydrangea typically thrive in fond shadiness or filtered sunshine , and when they are planted in full Lord’s Day , the intense warmth and light can conquer their power to produce efflorescence . This is particularly true for certain hydrangea potpourri , such as the mophead or bigleaf hydrangeas ( Hydrangea macrophylla ) , which are known for their great , showy blooms .
The extravagant sun photo can lead to a lack of bud organization or cause the buds to dry out out and fail to open up . This can be frustrating for gardeners who are eagerly look the beautiful blooms . In some cases , the plant may still produce blooms , but they may be small , thin , or less vibrant in color .
Overwatering and over - fertilizing can also contribute to the damaging effects of too much sun . Hydrangeas prefer damp soil , but not overly saturated or waterlogged conditions . When the soil is constantly wet , it can lead to root rot or other fungal disease , which further break the industrial plant ’ power to withstand the sunshine . likewise , excessive dressing can leave in exuberant foliage growth , but at the expense of bloom production .
To mitigate the effects of too much sun , it is of import to provide some form of shade or protective covering for hydrangeas . This can be achieved by planting them in areas with fond shade or using structures like arbor , mandrel , or umbrellas to provide strain sunlight . Additionally , even watering and see to it the soil is well - draining can aid forbid stress on the plants .
It is worth noting that not all hydrangea sort are equally regard by inordinate Lord’s Day exposure . Some varieties , such as the panicle hydrangeas ( Hydrangea paniculata ) and oakleaf hydrangea ( Hydrangea quercifolia ) , are more patient of of full sun and may still produce efflorescence even under acute sunlight . However , even these varieties can profit from some shade during the red-hot contribution of the day .
In my personal experience , I have date the damaging effects of too much sun on hydrangea . I had planted a beautiful mophead hydrangea in a spot that received full sun for most of the mean solar day . Initially , the plant seemed to be doing well , but as the summer advance , I noticed the bloom were modest and less abundant compared to other hydrangea in my garden . The leaves also showed sign of tan , turning brown and crispy . After some research and audience with a horticulture expert , I realized that the intense sun exposure was the main perpetrator . I make up one’s mind to transfer the hydrangea to a spot with filtered sunlight , and over prison term , it recover and began producing declamatory , more vibrant blooms .
To summarize , when hydrangea get too much Lord’s Day , it can block their flower production and lead to issues such as wilting , sunburned leaves , and smaller or sparse blooms . Providing shade , forefend overwatering and over - fertilizing , and selecting sun - tolerant hydrangea miscellany can help mitigate the negative burden of inordinate sunlight exposure .
