How feed hydrangeas in the spring ?
One of the key aspects of farming is feeding. This is especially true of flowering plants, such as hydrangea. Rich «nodding» blooms requires adequate nutrition, and to fully enjoy it, you need to know what to feed hydrangeas in different time of year. It is important to understand how her need for mineral substances during the season.
Why it is important to fertilize
Hydrangea, or hydrangea among gardeners is quite capricious plant, and, nevertheless, it can often be found both in the flower beds, and home window sills. It compensates for the demanding long, from late spring to autumn, blooms and huge, ball-shaped flowers of different colors. Hydrangeas for a lush flowering and active growth, fertilize regularly throughout the season. How feed hydrangeas in the spring ?
Without adequate nutrition when the root system is not getting the necessary minerals, the leaves fade and droop, because they have to «feed» the inflorescence; buds smaller, faster Bud, their amount decreases. In the slang of the growers, the situation can be described as – «the Bush was not pulled bloom.»
Proper and timely fertilizing hydrangeas:
- uniform promotes active growth of green mass;
- provides abundant and long blooming;
- promotes brighter, more saturated color of the flowers.
- strengthens the immune system;
- helps the Bush survive the winter.
Today, in order to purchase fertilizer, no – in the range can be found on the shelves of any specialty shops.
To choose a suitable, you need to understand which substances needed by the plant:
- Nitrogen – promotes green dial mass. Lack of it can stop absorption of other trace elements.
- Phosphorus is «responsible» for budding and flowering helps the plant to fight fungal diseases.
- Potassium – the basis of immunity, with a sufficient quantity helps the plant to survive adverse conditions.
- Magnesium – affects the color of the petals. Important during budding, with its lack of ovaries crumble.
- Iron – necessary for the formation of the immune system and uniform coloring of the leaves.
Depending on the growth phase of choose feeding with a predominance of the desired trace elements.
Fertilizing in the spring
Feed hydrangeas in the spring immediately after the snow melts. Use nitrogen-rich fast-dissolving agents such as urea. It stimulates the development of green mass and active growth of strong side shoots and subsequently that they will form buds. To stimulate immunity at a time make ammonium sulfate.
For each plant 5 litres of water to throw on 1 tbsp of each fertilizer, stirred until complete dissolution of crystals. Formed tree trunks (shed clean water) and poured the resulting liquid gradually, letting it to soak in. Urea can be replaced with chicken litter, dissolved at a ratio of 1:20. Infusion of mullein make more concentrated 1:10.
Organic fertilizer for hydrangeas is used very carefully and only in a period of high requirement for nitrogen. Concentration not exceed, in order not to damage the root system.
The following feeding plan in late spring, when hydrangea begins laying the buds. Use complex fertilizers for flowering plants, diluted in the dosage of 1 tablespoon per 10 liters, bring 2-3 liters every tree.
Fertilizing hydrangeas in the summer
First fertilizing hydrangeas is done in the summer in early June. Before flowering it is important to provide the Bush with a sufficient amount of phosphorus, so choose fertilizers with a high content of it. The best option would be double superphosphate, where the phosphorus is contained in easily digestible form. Besides it dissolves better than ordinary superphosphate. How feed hydrangeas in the spring ?
1 tbsp the drug is first dissolved in a small amount of warm water, warming up the crystals, then the resulting mixture is diluted to 10 L. If we pour double superphosphate, once in the bucket, it will not dissolve. To replace it you can specialized complex fertilizer for hydrangeas, azaleas and rhododendrons. They can be found from manufacturers such as Agrecol, Yara Villa or Planton. Some gardeners have successfully replaced their complex mixtures of Vertica (Kemira). Diluted according to instructions. In July and August, re-fertilize the shrubs using the same drugs.
Fertilizing in the fall
Since the beginning of September hydrangea, wintering in the open ground, begin to prepare for dormancy. To strengthen roots and shoots, exhausted long flowering, use potassium sulfate – 2 tbsp in a bucket of water will suffice. In October to stimulate immunity and extra protection against fungal infections using iron sulfate. A kind of fertilizer for hydrangeas in the fall can become mulch. If after cutting to cover the trunks of peat or pine needles, they partially decompose by spring, and when the plant is again touched in growth, will become an additional source of nitrogen.
Feeding folk remedies
Hydrangea responds well to traditional remedies that increase the acidity of the soil. Spring can be used diluted in water yeast (1 packet and 1 tbsp sugar in a bucket of liquid). Summer hydrangeas «like» feeding the kefir whey (need to be diluted with water in proportion 1:4) or citric acid (3-4 crystals per liter of water).
In July hydrangea pour nettle infusion (1:3). It will extend flowering and make the color of the blossoms brighter. Autumn will have a positive impact on the bushes spraying slightly pink solution of potassium permanganate. Remember that to feed a hydrangea ash can not be – it leads to a shift reaction of the soil to the alkaline side.
Than water the hydrangea to change the colour of the inflorescence
The color of the inflorescences hydrangea depends on the acidity of the soil. At neutral or slightly alkaline reaction, it becomes pinkish, with sour – blue. Respectively, affecting the pH can change the color of the petals.
After the introduction into the soil of pine needles or peat, which have a pronounced acid reaction, the inflorescence of hydrangea acquire a bluish tint. The same result can be obtained by mixing 1 tbsp. l. potassium chloride and potassium sulphate with 5 liters of peat, and spreading the mixture as mulch in tree trunks zone.
Fun to use aljumokalievyh alum; for hydrangeas, which has the ability to accumulate in tissues aluminium, it will lead to the deep blue color of the petals. For violet shades mixed potassium sulfate and ammonium, and 1 tablespoon with a bucket of water. Pour on 5 liter under every Bush in the period of budding. To consolidate the results of the procedure before blooming of the first flowers repeated three times.
Pinkish shades are using potassium permanganate or complex liquid fertilizer with a slightly alkaline reaction. The same result is the use of ash or lime (1 Cup) mixed with a bucket of water. Abuse of these substances is not necessary – a shift of pH to the alkaline side weakens the hydrangea. White color, and accordingly, a neutral pH can be achieved by «diluting» the soil with sand or coconut fiber.
Fertilizer potted hydrangeas
Leaves on a hydrangea growing in the indoor environment, awake early. Accordingly, the feeding starts immediately after planting and leaving the plants from dormancy in the mid – to- late February. Early spring feeding, as in the case of open ground, aimed at the saturation of nitrogen. Use any fertilizer with a high content of this trace element. Organic pot is better not to add – not decomposed parts will start to humus, which will trigger intensive development of pathogenic microflora. To stimulate the growth of leaves and lateral shoots can, spraying the shrub with a solution of succinic acid. The working solution is prepared according to the manufacturer’s instructions, as it may be different purity, respectively, dosages may vary
In pots «greedy» hydrangea will need more fertilizing, at least 2 per month. The need for nourishment is easy to determine – if the hydrangeas brighten the leaves, then you fertilize it a little. In spring and summer, as open-ground plants, a dressing should prevail phosphorus and potassium. Autumn in the composition of the fertilizer should be potassium and iron.
Growing hydrangeas, it is necessary to provide the necessary amount of micronutrients. To do this, use organic and mineral fertilizers. During the season, mixtures with a predominance of different substances, adapting to the needs and biological rhythms of the plants. How feed hydrangeas in the spring ?
