Fertilizing roses trace elements do no more than twice per season (at the beginning of the growing season in the spring and during flowering), introducing them with a solution of complete fertilizer or liquid manure. In addition to all the necessary roses chemical elements, slurry also contains bacteria that mineralize organic compounds are not available to plants, converting them into digestible form.
Slurry preparing to feed the roses as follows: fill capacity of 80% fresh mullein, fill it up to the top with water, adding 10 liters per 100 g of wood ash. For two weeks every solution mix. Since the slurry is dominated by nitrogen in fertilizer must be added phosphate and potash fertilizers.
For fertilizing roses use the following solutions (10 liters per 1 square. Meter. First fertilizing (May): Water - 9 l, mullein 1 kg superphosphate 20-30 g of potassium sulphate 15-20 g, the second top dressing (in July) - 9 liters of water, 1 kg of mullein, 20-25 g of superphosphate, potassium sulphate 25-30 g When feeding roses make better manure into the soil, and all fertilizers to make a foliar application on the leaves - it requires three doses times less.
Foliar feeding is not salinization soil (ballast, which is present in fertilizer), are not destroyed by soil microorganisms and earthworms. Foliar fertilizer is made only in the evening to drop with the fertilizer as long as possible to dry out the leaves.
Sales, liquid completely soluble fertilizers.
For soil fertilizing roses are well established: first - "Strawberry concentrate", which is composed of soluble nitrogen, phosphorus and potassium (but it acidifies the soil, so you have to make more wood ash), and in the fall - fertilizer "Autumn" in granules ( or the leaves can sprinkle potassium monophosphate).
For foliar feeding roses quite suitable complex liquid fertilizer for indoor plants: it is but essential nutrients, contains all the essential micronutrient. But in any case, can not be ruled out fertilizing roses spring making precast compost or humus.
If the soil in the spring in the rose garden was filled with manure, liquid fertilizer only restrict superphosphate and potassium salt in the amounts indicated: the use of manure in this case, lead to a significant deterioration of the hardiness of roses. Too much nitrogen fertilization (including manure) leads to a violent growth of young shoots in rose bushes, which do not have time to mature to fall - they are herbaceous, unable to move the slightest negative temperatures.
These herbaceous shoots substitution removed completely in the fall, until the base (on the ring), because in the winter even with the most reliable shelter they inevitably will freeze and thaw at zagniyut. Necrosis in this case extend to healthy wood, and rose may die.
