Preparing for the first feeding
Spring feeding is a key procedure for obtaining a high-quality, bountiful harvest. Before carrying out it, it is necessary to carry out preliminary preparation:
- Remove branches that have frozen over the winter.
- Collect the leaves left over from the fall.
- Weeds that have appeared in the spring, weed by hand, so as not to damage the root system.
- Remember: the beginning of April is the time for the first feeding (provided there is sufficient moisture in the soil). At this time, it is advisable to apply nitrogen fertilizers of about 70-90 grams per square meter, sowing them on the ground around the bushes.
- Mulch with peat, compost, or semi-decomposed manure. This will make it possible to retain moisture, earthworms will appear, which will make the soil loose, saturate it with air.
Diagnosis by appearance
With regard to subsequent dressings, then you need to observe the appearance of the leaves and shoots of raspberries, they will be able to suggest which substances are lacking in plants. Watch out for the following signals:
- If the raspberry leaves are small, faded, and have noticeably slowed down their growth, the plants lack nitrogen.
- Huge, dark green leaves signal possible excess nitrogen availability, which can lead to a sharp decrease in yield levels. Unripe fruits in such cases simply crumble.
- When small yellowed leaves with dark veins appear, you should know that these are signs of iron deficiency in the soil.
- When the leaves have slowed down, started to turn yellow from the middle to the edges, the plant informs you about the lack of magnesium.
- Weak, thin and pale shoots are evidence of a phosphorus deficiency in the soil.
- If the leaves look like they have burnt edges, then the plant is deficient in potassium. It is also a risk not to endure the winter.
- The pale tops of raspberry bushes indicate an insufficient presence of calcium in the soil.
By reacting in time to the signals given by the plant, you can adjust the composition of the spring feeding of raspberries and have time to get a good harvest of berries. In addition, timely assistance will prepare the plant for further normal growth and development.
An effective, environmentally friendly way of feeding is the introduction of organic matter in the spring. It can be a solution of mullein with water in a ratio of one to ten or bird droppings in water in a ratio of one to twenty.
As a mulching layer, you can make a covering of bone meal around the raspberry bushes in early spring.
It is good to use the finished preparation of Kemir, three tablespoons of which must be diluted in ten liters of water. Pour raspberry bushes with this solution at the rate of one liter per bush.
A cheap and effective means of feeding is weed tincture. To do this, it is necessary to grind the nettle, comfrey (it is preferable to take these particular plants, since they are rich in nitrogen and potassium).
Pour one kilogram of the mixture with ten liters of water and leave for a week and a half, stirring daily. You can add some lemon balm or valerian to enhance the flavor. Dilute the present solution with water in a ratio of one to ten to fifteen and water the raspberry bushes (two liters under the bush).
Tips from experienced gardeners:
- Apply organic on a cool, cloudy day.
- If the soil is dry, moisten it well before applying organic fertilizers.
- Avoid getting liquid solutions of organic matter on the stems and leaves of plants.
- When you prepare a tincture from weeds or bird droppings, mullein, do not close the container tightly, air access is required, otherwise the fermentation process will stop.
Spring feeding of raspberries with organic substances will have a positive effect on the size and quality of the berries of the future harvest, they will be larger and sweeter.
Mineral spring feeding of raspberries
Mineral fertilization must be carried out in the spring to obtain the most positive effect on plants. Raspberries need phosphates, potassium and nitrogen salts.
Potash fertilizers can be successfully replaced with ash. It is nutritious, does not contain harmful substances, and is economical. Ash is brought in in the spring at the rate of 100-150 g per square meter of area both in dry and in the form of a solution.
It is recommended to apply nitrogen fertilizers in the spring (15-18 g per square meter of area).
If there is a desire to use a complex mineral dressing, then it is prepared from ammonium nitrate, potassium and superphosphate in a ratio of 1: 1: 2. One hundred grams of the mixture is diluted with ten liters of water.
The use of such a complex of minerals can be carried out once in early spring or applied twice - in early spring and at the end. Experienced gardeners practice the use of mineral and organic fertilizers at the same time, but constant monitoring of the reaction of plants is needed.
If the yield of raspberries exceeds one kilogram of berries from the bush, the feeding was carried out correctly.
