What not to fertilize roses with: you won't see flowers in the summer
Rose blooms are an indispensable sign of summer. However, every flower lover wants their bush to bloom more magnificently than others. Fertilizing the plant can help with this. But sometimes it happens that after fertilizing, the flower feels even worse than before. This is evidence of a care mistake.
OBOZREVATEL tells you exactly what to avoid when fertilizing roses. And what fertilizers and how to apply them to make the plant feel its best and bloom lushly.
Common mistakes when fertilizing roses
Use of fresh manure: Freshly collected manure, including poultry manure, is not good for caring for roses. When fresh, it contains too many nutrients and can burn the root system of the flower. That is why you should not fertilize it with fresh manure. This organic fertilizer should be stored for about a year before it can be used in the garden.
Use of phosphate fertilizers without potassium: Roses are very fond of phosphorus fertilization and respond well to it. It can be applied throughout the season. However it would be a mistake to use phosphorus alone without potassium. It is in tandem that these substances help the flower to release as many buds as possible.
Excessive nitrogen: Nitrogen is another substance that helps roses bloom lushly. Therefore, some growers generously treat flower bushes with it in the spring. The first warmth is the right time to apply nitrogen fertilizers, but the sense of proportion should not betray you because an excess of nitrogen slows down the development of rosebuds. Also, the substance should not be used in the fall, as it can reduce the winter hardiness of flowers.
What fertilizers are suitable for roses
A good option for organic fertilizer is an infusion of weeds. After breaking through the unwanted plants on the site, the green mass weighing about 300-350 grams should be crushed and put into a bucket. Add 2 tablespoons of soda ash and cover with water. The fertilizer should ferment for about two weeks, after which it should be filtered and diluted with water in a ratio of 3:10. This water is used for foliar feeding, i.e. spraying the bushes.
Roses also respond well to wood ash - it contains a lot of phosphorus and potassium, which they need for flowering. The dry mass is simply poured under the bush and gently dug in so that the ash mixes with the soil. For one plant, 200-300 grams of ash will be enough. It should be applied before flowering.
Ash can also be used to prepare a spray that will protect the rose from fungus. To do this, mix it with water in a ratio of 1:2 and leave it for about 2-3 days. The bushes are sprayed with the strained liquid. It can also be poured under the root of the plant.
If you plan to fertilize the rose with manure, you need to take rotted manure and insist on water. Chicken manure is diluted in a ratio of 1:20, and cow manure 1:10. The liquid should be left to stand in the air for 7-10 days, and then water the bushes with it.
How to fertilize roses properly
There are two main methods of fertilizing: root and foliar. The first is watering the plant with a nutrient solution or applying dry fertilizer to the soil right at its roots. The second is spraying because plants also receive a lot of nutrition through their leaves and stems.
To feed a rose using the root method, you need to make a small depression at a distance of 15 cm from the stem and fill it with fresh soil mixed with fertilizer, then cover it with the soil familiar to the plant and water it. Some of the substances will dissolve immediately, while the rest will be dissolved by the rains and the flower will gradually absorb them. You can also water the rose under the root with a fertilizer solution.
If the soil for roses is good in itself, then it is better to nourish it foliarly - by spraying. It is better to do this at sunset so that the liquid does not evaporate under the sun but has time to seep through the leaves.
