It is imperative to feed the lilacs in the spring. Although the culture is considered wild, soil nutrition is the key to a long and vibrant flowering. Fertilizing the bush is required throughout the season.
Why do you need to feed lilacs
An ornamental shrub is an unpretentious plant. Undemanding to the composition of the soil, it can grow on any land. It tolerates cold well. However, to get a lush bloom, you need to fertilize the lilac. The bush itself can grow, of course, but there will be no bright inflorescences.
Benefits of regular eating lilacs:
- active growth;
- the formation of large flowers;
- rich color;
- increased resistance to fungal, viral diseases;
- high frost resistance.
Rapid development and abundant flowering depend on the content of mineral components in the soil. Therefore, it is worth fertilizing lilacs from spring to autumn.
What dressings are suitable for lilacs
Horticultural crops respond well to almost all nutrients. The composition and amount of dressings depend on the age, size of the bush, condition, soil composition, seasonality, climatic conditions.
Organic
Lilac needs organic matter, since it improves the structure, warms the soil, and promotes the development of beneficial microflora. Organic components contain micro and macro elements in optimal proportions for the shrub.
The lack of natural elements in the soil provokes yellowing and curling of the leaves, the roots suffer, the inflorescences noticeably decrease in size. Choice of nutritional supplements:
- manure;
- humus;
- bird droppings;
- compost;
- peat.
Mineral
Nitrogen activates the formation of chlorophyll, the appearance of organic compounds in foliage, helps in the process of photosynthesis. The substance stimulates the seedlings to root and grow quickly.
Potassium increases the plant's resistance to diseases, adverse weather conditions, promotes painless recovery after transplantation.
Phosphorus is responsible for metabolic processes, provides oxygen and minerals. Phosphorus influences cell division and growth of the bush.
Dolomite flour, limestone, chalk - dressing obtained by processing limestone. They are used to normalize the acidity of the soil.
Complex
There are complex compounds that include several mineral components at once: nitrophoska, ammophos, molybdates. These chemical elements are safe for shrubs and soil.
Complex fertilizers include wood ash. It contains over 30 useful elements. Both garden and horticultural crops are fed with ash. The substance combines well with organics.
How to fertilize lilacs after planting
A light, drained soil is suitable for lilacs, which will allow water and air to be delivered to the roots without delay. During planting of seedlings, the soil is fertilized. Mineral and organic substances are introduced into the depression:
- Drainage from gravel, small stones.
- Dolomite flour, lime if the soil is acidic.
- To regulate air and water permeability, sand is added to the clay soil, and clay is added to the sandy soil.
- Pour a mixture of organic matter: humus and manure in equal parts.
- Superphosphate - 500 g, potassium sulfate - 150 g, bone meal - 300 g.
- The next layer is a bucket of fertile soil.
- All components are thoroughly mixed.
- After planting, be sure to mulch the bush with peat, dry leaves, sawdust, hay, needles.
If the culture grows slowly, then the root system is developing poorly. In this case, the seedling needs to be fed with organic substances 2 times in the spring-summer season.
How to fertilize lilacs in spring
Spring care for lilacs involves feeding with mineral and organic substances. Fertilization begins immediately after the disappearance of the snow cover. In mid-March, the bush wakes up, buds are laid. Formation will help a solution of mullein in proportions of 1:10. In the absence of this component, manure, compost, and bird droppings are used. Depending on the size, 1-3 buckets of nutrient fluid are enough for one bush.
The soil under the lilac is loosened to a depth of 6-7 cm, and then the mixture is poured. After mulching the near-stem circle with hay, straw. So natural components will help preserve useful trace elements in the soil.
Organic fertilizers are also applied dry. Then they perform not only the functions of feeding, but also mulch. On average, 10-25 kg of dry humus are consumed per lilac bush.
Feeding lilacs with mineral preparations occurs in the spring, when the shoots will grow. This is somewhere in the middle of April. Fertilize the soil with nitrogen, which lilacs need for active growth, long and lush flowering. Gardeners are advised to use 80 g of ammonium nitrate under a bush or urea, 50 g. It is necessary to re-feed with nitrogen-containing preparations with the onset of May.
In addition, during budding, lilacs can be fertilized with wood ash. It contains enough useful elements for the full formation of buds. Ash weighing 200 g is dissolved in 10 l of water. For an adult bush, 1 bucket of nutrient fluid is enough.
How to feed lilacs in spring for lush flowering
When the inflorescences have formed, the lilac should be fed with nitrogen-containing preparations for the last time in the spring. Gardeners use ammonium nitrate for lush flowering, as well as potash and phosphorus complex products.
In the phase of the appearance of flowers, the ground is already covered with grass, therefore, before applying fertilizers, the near-stem circle must be cleared and loosened up. Around the same time, bright green beetles appear on the inflorescences, which feed on delicate petals. As a result, the lilac looks unattractive. Beetles must be collected in a timely manner.
Features of feeding lilacs after flowering
When the lilac has faded, the life process stops, the plant rests. However, young bushes need to be watered once every two weeks. Adults over 4-5 years old do not need frequent watering, otherwise the roots can rot. They are more resistant to drought than young ones.
Withered inflorescences are removed with a sharp pruner. If you leave them on a bush, then the lilac will spend a lot of energy on the formation of fruits. This will negatively affect further vegetation and flowering next year.
At the end of July, lilacs should be fed without waiting for autumn. However, it is undesirable to use nitrogen. Potassium and phosphorus preparations are mainly used. They have a beneficial effect on the root system. Can be fed with ash compounds that nourish the plant well. The amount of fertilizer for one lilac bush:
- potash - 25-30 g;
- phosphoric - 50 g;
- potassium compounds - 30 g.
Lilacs are fed every 3 years.
How and what can you feed lilacs in the fall
With the arrival of autumn, activities for the care of lilacs do not cease to be held. It was at this time that the complex nutrition of the bush was the second most important. In the fall, lilacs require fertilizing with fertilizers at the maximum dosage. Thus, it will be possible to restore the composition of the soil.
It is not recommended to use nitrogen-containing preparations before winter, as they can provoke the growth of young shoots before frost. It will be useful to thin out the bush, make sanitary pruning.
In the autumn, it is preferable to alternate organic and mineral fertilizers. But do not contribute everything at the same time. The dosages are the same as in the spring. You can only feed it with organic matter: chicken droppings, manure, mullein, humus. The volume of the nutrient solution per 1 sq. m is 15-20 liters.
Gardeners recommend using dry organic fertilizers. They are laid under a bush after the last watering before winter. A layer of mulch will preserve moisture, protect the roots from frost, and nourish the plant in doses. The amount of organic matter for one plant is 10-20 kg.
Foliar top dressing of lilacs
The plant also prefers foliar treatments. As a rule, such feeding of lilacs is carried out in summer and autumn. Agricola is suitable for a flowering bush. A solution of micronutrient fertilizers is prepared as follows:
- the contents of the package 25 g are dissolved in a bucket of warm water;
- pour the nutrient mixture into a spray container;
- all leaves are carefully processed.
Instead of a ready-made fertilizer, you can make the composition yourself. To do this, you need 1 g of copper sulfate, 5 g of manganese, 2 g of zinc sulfate and the same amount of ammonium molybdate. The amount of powder is calculated for 10 liters of water. The solution is enough to process several lilac bushes.
How to fertilize correctly
Before fertilizing the lilac, the area should be cleared of weeds and excess growth. Weed the near-stem circle and loosen it to a depth of 8-10 cm. At the same time, try to do everything carefully so as not to hurt the root system of the bush.
Gardeners usually feed lilacs in the spring with minerals dissolved in water or dry nutrients. The mixture is not poured directly under the trunk, but a groove is made that runs along the perimeter of the bush. Distance from the center 50 cm.Solid substances are embedded to a depth of 7-8 cm.
To obtain a luxurious lilac bloom, dosages should not be neglected. It is important to follow the instructions and apply feeding in moderation so as not to provoke an excess of nutrients. Otherwise, contrary to expectations, the overfed plant noticeably weakens, immunity and resistance to diseases decrease. Subsequently, the bush can be exposed to viral and fungal infections, parasite attacks. An overdose of nitrogen-containing drugs can provoke:
- sunburn;
- damage to the bark;
- stem rot;
- chlorosis;
- defeat by a scabbard, a scale insect.
Lilacs will become exposed to weather conditions, and the frost resistance index will decrease. Freezing cracks may appear, which in turn will lead to poor wintering.
You need to be careful with organic fertilizers. It is better to add more water so that the solution is not very concentrated. Such a mixture is capable of burning delicate roots and destroying the plant.
Conclusion
You need to feed the lilacs in the spring immediately after the snow melts and follow the diet throughout the season. Humus-rich, light, nutritious soil will be the best environment for growing ornamental shrubs. The quality of lilac flowering directly depends on the presence of useful elements in the soil.
