Hydrangeas are loved by flower lovers for their gorgeous flower bulbs and changing colors, and are often used as decorations for courtyards or balconies. However, many people find that hydrangeas do not grow new leaves or even bloom when they are maintained. In fact, hydrangea has "three fears", and if you don't pay attention to it, it can easily affect its growth and flowering. Let's take a look at what these three "fears" are and find out how to solve them.
1. Fear of strong light exposure
Hydrangeas prefer mild sunlight, but their leaves can easily get sunburned if exposed to strong sunlight for a long time. Especially in summer, direct sunlight can cause the leaves to turn yellow, scorch, and even show signs of burns. This not only affects the ornamental effect, but also weakens the overall health of the plant.
To avoid this, it is best to place the hydrangea in a place where there is scattered light, such as a north window or a balcony with shade. If it can only be planted outdoors, it is advisable to give proper shade at noon when the sun is at its strongest, such as using shade netting or moving to the shade of a tree. In addition, it can increase the humidity of the air and help hydrangeas survive the hot summer months. It is also important to spray and keep the soil moist at the right time, so that the leaves are fuller and shinier.
2. Fear of overwatering
Many flower lovers mistakenly believe that hydrangeas need a lot of water, so they water them frequently, which often backfires. Overwatering can cause the soil to become too wet for a long time, which can trigger root rot. In this case, not only is it difficult for new leaves to grow, but even existing leaves will gradually turn yellow and fall off, which seriously affects the health of the plant.
The correct way to do this is to know how often and how much you should water. During the growing season of hydrangeas, it is important to keep the soil moist but not waterlogged. In general, when the top layer of the soil is dry, it can be watered in moderation to ensure that the water can penetrate the roots. Especially in winter, it is important to reduce the frequency of watering, as the growth rate of hydrangeas slows down and the need for water is correspondingly reduced. To better judge if you need watering, you can use your finger to gently stick your finger into the soil and if it feels dry, then water.
3. Fear of low temperature frostbite
Although hydrangeas are more hardy, extreme low temperatures can also damage them. Especially in the cold winter, if effective insulation measures are not taken, hydrangeas are susceptible to frost damage, which is manifested as leaf blackening, wilting, and even the death of the whole plant in severe cases. This is why many people find that after winter, hydrangeas do not grow as well as before.
To avoid frostbite, there are some protective measures that can be taken before winter sets in. For example, move hydrangeas indoors and place them in a well-lit place, but avoid being near heating equipment to prevent the leaves from being roasted. If it is not possible to move indoors, the plant can be covered with a cold-proof cloth or straw to protect the roots from frost damage. In addition, proper pruning can be done before winter to reduce the transpiration of the plant and also help hydrangeas survive the cold winter.
Overall, understanding these "fears" of hydrangeas and coping with them is key to ensuring their healthy growth and beautiful flowering. In addition to these basic considerations, fertilization is also important. You can choose a special fertilizer suitable for hydrangeas and apply it every two weeks during the growing season to promote new leaf growth and bud formation. Before flowering, you can increase the amount of phosphorus and potassium fertilizer to help the flowers become bigger and more colorful.
Although the maintenance of hydrangeas may seem complicated, they are still very easy to maintain as long as you master the right methods. If your hydrangeas don't grow new leaves or bloom, try adjusting the light, moisture and temperature, and you may soon see them look new. Raising flowers is an art that requires patience and care, and I hope everyone can raise beautiful hydrangeas and make them the most eye-catching scenery in the home.
