The decorative flower hydrangea is classified as a capricious crop. Not everyone succeeds in getting lush, bright buds. Hydrangea usually does not bloom for several reasons: improper care, poorly tolerated winter, insufficient soil acidity. There are other factors that influence the formation of flower stalks.
Features of hydrangea flowering
This bush crop blooms annually with proper care. The formation of buds lasts throughout the warm period of the year. In Russia, deciduous varieties of hydrangeas with paniculate, spherical or corymbose inflorescences are grown.
The shrub's flowers are mostly white
The color depends on the level of acid in the soil; for example, if pink hydrangea does not bloom, a small amount of alkali is added to the soil.
In soils that are neutral in composition, the buds of the crop will be beige or cream
If blue hydrangea does not bloom, the soil lacks aluminum, which the plant easily absorbs.
The acidity of the soil is increased to color the hydrangea blue.
In order for the crop to produce buds and for them to grow lush and large, a number of rules must be followed when rooting the seedling.The main thing is that the planting material is of high quality, varietal, obtained from a healthy mother bush.
Other conditions for flowering shrubs:
- the right place for landing;
- regular watering;
- fertilizing;
- protection from frost.
With proper and high-quality care, you can accelerate the growth of the bush and stimulate the formation of buds.
When should hydrangea bloom?
The culture blooms in early June. The budding period lasts until the onset of the first cold weather, this is the beginning or mid-September. If large-leaved hydrangea does not bloom during the specified period, it means that the technology for its cultivation has been violated.
Frequent fertilizing causes the foliage of the crop to grow, but it will never produce buds.
Poor and irregular watering also reduces the likelihood that hydrangeas will bloom in the summer.
Why garden hydrangeas don't bloom
In the garden, varietal hydrangeas often do not bloom the following season after transplantation. These capricious plants must survive the winter successfully. You cannot wait until the air temperature drops to 0°C, in which case the flower buds will freeze and the buds will not form in the next season.
Immediately after shedding, the hydrangea is pruned and wrapped for the winter.
Flowers growing in the garden in tubs or pots are transferred to the basement; indoors, hydrangea can easily withstand the winter. This is the main condition for abundant budding next year.
In the spring, hydrangeas are also pruned.
If you do not get rid of old, dry, damaged stems, the plant will weaken and will not have the strength to form buds
Well-developed, green shoots from last season cannot be pruned. It is at their ends that the buds are laid.
An excess of fertilizers in garden soil leads to the growth of green mass, and the formation of flower stalks is suspended. For the same reason, it is not recommended to apply nitrogen fertilizers to the soil at the end of summer and autumn. By winter, all biological processes of the plant must stop; during the cold period, the flower enters a state of dormancy.
For different types of garden hydrangea, there are objective reasons for the lack of buds. Some of these shrubs are frost hardy, but other factors also influence their growth.
Paniculata hydrangea blooms poorly due to the poor composition of the soil.
This crop requires soil half mixed with clay, its acidity should be minimal
The species is frost-resistant, so cold does not affect the formation of buds. And irregular, meager feeding leads to the fact that the flowers become small and pale.
Tree hydrangea does not bloom in the garden due to lack of moisture. In summer it should be regular, abundant watering. The crop tolerates cold well, but it needs to be wrapped up for the winter, since the buds of the plant die at the first frost.
Regular feeding is necessary for tree crops. In early spring, fertilizers are applied to form green mass, and at the end of May - to stimulate the formation of buds.
If tree hydrangea is not fed and watered regularly, it will result in a large green shrub that does not bloom.
Serrata hydrangea does not bloom in the garden due to the weak acidity of the soil. This factor is the most important for the formation of buds. Also, this crop does not tolerate stagnation of water in the soil.Regular loosening of the soil will help prevent root rot. In the northern regions of Russia, the crop does not bloom, as it does not tolerate cold at all.
The species is recommended to be planted in the southern and central parts of the country
Climbing (climbing) hydrangea does not bloom in cold regions. This species is intended for cultivation in the south.
The flower cannot be planted in the sun, it prefers partial shade
Calcareous soil should be avoided; the crop prefers acidic, loose soil. Spring pruning is also important for it; they stimulate the growth of shoots on which flower stalks form.
Petiole hydrangea does not bloom if planted in the shade or against the wall of a house; the culture develops well in full sunlight.
The first flowers appear on this plant 5 years after planting
To stimulate flower stalks, the soil acidity level is increased to 4-6.5 units.
How to make hydrangea bloom
If garden hydrangea largeleaf (broad-leaved) does not bloom, this is a reaction to improper care or planting. The situation can be corrected by providing the plant with all the necessary conditions for growth.
Trimming
For hydrangeas, autumn and spring pruning are important. As soon as the plant fades, preparations for winter begin. At this stage, it is important to properly shorten the shoots in order to stimulate the growth of new ones next spring.
First, trim off the remains of dried buds
Then remove wilted or damaged stems. They also shorten the shoots growing inside the crown, thickening it. Strong young stems, at the ends of which young buds form in the fall, are not pruned.
In the spring, sanitary pruning of the plant is carried out, dry and broken branches are removed. It is recommended to prune paniculate and tree hydrangeas in the spring, before flowering begins.Other types of this crop tolerate autumn pruning better.
Preparing for winter
In autumn, dried peduncles and lower leaves are removed from hydrangeas; the upper leaves must be left. Then potassium and phosphorus fertilizers are applied at the root. The plant is thoroughly watered and the soil is loosened.
In central Russia, all types of hydrangeas need shelter for the winter. With the arrival of the first cold weather, the crop may die.
Low shrubs up to 1 m are covered with peat, covered with film on top, pressing down the covering material with boards or staples along the edges.
Tall bushes are tied with rope and tilted towards the ground. Boards are placed under the crown and nails are hammered into them. Hydrangeas are tied to them by the ends of the shoots. Sawdust or dry leaves are poured on top. The structure can be secured with roofing felt.
In regions with cold winters, hydrangea is covered more carefully. First, the bush is tied with a rope, the shoots are bent to the ground, securing them with metal brackets. The central part of the bush is covered with peat, and the shoots are covered with spruce.
The structure is covered from above with a durable covering material, secured with bricks or boards along the edges
Old shrubs whose stems have become woody are not twisted. They are wrapped in covering material and tied with rope. Metal semicircular brackets are placed on top of the structure, and dry leaves are poured inside the structure. The top of the hydrangea is covered with sheets of roofing material.
In the southern regions, hydrangea is simply spudded in the fall. Young plants up to 2 years old are covered carefully. Shrubs 3 years and older are more resistant to frost.
Watering
The plant is watered only with settled water at room temperature. They do this regularly.One shrub requires 10 or more liters of water, depending on the size of the rhizome.
In the summer heat, the bush is watered every 3 days. If the summer is cool, once a week is enough.
Water should only be poured from a watering can with a sprayer; a hose is not suitable for this purpose; the roots of the plant should not be exposed
Soil acidity
The composition of the soil mainly affects the flowering and color of the crop. Especially if the hydrangea has not bloomed for the second year, it is important to determine the acidity of the soil and, if necessary, increase it. For budding and abundant flowering, slightly acidic and moderately acidic soils (4-6.5 pH) are required.
It is necessary to acidify the soil annually, since during the growth process hydrangea draws out nutrients and the soil becomes depleted. In the spring, solutions of saltpeter and iron sulfate are added to it. A slightly acidic vinegar solution will also help raise the acidity of the soil. Citric acid is also used for the same purpose (2 tsp per bucket of water).
If the soil composition is optimal, the plant will produce blue buds; when the acidity is insufficient, the flowers will be pink
Top dressing
Due to lack of nutrients, hydrangea does not bloom. Fertilizing is done according to the schedule for flowering crops:
- In early spring, before the formation of flower stalks, complex fertilizing with nitrogen, phosphorus, potassium, magnesium, and zinc is applied every week.
- Between mineral fertilizing, the plant is mulched or watered once a week with a solution of settled plant waste.
- During bud formation and flowering, potassium fertilizers are applied once every 10 days. Nitrogen is not needed during this period.
- As soon as the hydrangea fades, it is fed with phosphorus in the fall. This will strengthen the plant and increase the winter hardiness of the buds.
At the same time, a solution of cow manure (a liter jar per bucket of water) is used as a nutrient irrigation.
If the hydrangea does not bloom, the soil is regularly moistened, loosened, and its qualitative composition is improved.
Tips for caring for hydrangeas
If the hydrangea does not bloom, in addition to basic care, apply the advice of experienced flower growers. Sometimes a little trick can make a capricious crop bloom in early May.
Secrets of abundant flowering:
- If large-leaved hydrangea does not bloom, it does not need to be pruned in the fall. Peduncles form at the ends of last year's shoots.
- In regions with cold winters, dried buds are not cut off in the fall; they provide additional protection to the developing buds. You can clear the bush of dry vegetation in the spring.
- A good fertilizer for hydrangeas that do not bloom is coffee grounds. It is mixed with the top layer of soil near the tree trunk.
- To get blue buds, add 20 g of aluminum alum or metal filings to 1 kg of soil near the bush.
- If the hydrangea, which overwinters in tubs in the basement, is watered occasionally, it will sprout new shoots in February, it’s time to move the flower to a brighter place.
- After watering, it is better to mulch the tree trunk circle rather than loosen the soil.
When digging the soil there is a possibility of exposing the roots, but this should not be allowed
Hydrangea is a heat-loving and light-loving crop. If it does not bloom, the plant may not have enough light and heat.
Conclusion
Hydrangea does not bloom in the garden if the climate or soil composition is not suitable for it. These are the main factors influencing the formation of buds. If the plant has enough heat and light, check the acidity of the soil. She must be tall.By regularly watering and feeding this crop, providing it with a warm winter, in the spring you get a beautiful ornamental plant strewn with large, lush buds.
