1. It depends on the variety
Roses are not inherently susceptible to disease and pests - however, in some breeds, the appearance of the flowers or intense scent has been and continues to receive more attention than the ruggedness of the plants. But there are also particularly insensitive varieties. These can be recognized by the so-called ADR predicate. In the General German Rose Novelty Test, the resistance of a variety to pests and winter hardiness, flowering, fragrance and growth habit are evaluated over several years. Only roses that have passed this test will be marked as ADR roses. They are considered to be less susceptible to the typical rose diseases and can do without spraying.
2. Good rose cut, strong plants
When the forsythia flower, the best time for the rose cut is that should not be too timid. Well sharpened scissors provide clean interfaces that are less susceptible to pathogens than frayed cuts. Always cut an angle of about half an centimeter above an outward bud to allow rainwater to drain. Cuttings falling on the ground are potential sources of disease and should be disposed of immediately. Old shoots and leaves, on which fungal spores often overwinter, are removed thoroughly.
Find an outward-looking bud and cut the branch about half an inch above
3. Protect the roots of the roses from voleurs
If a rose wilts all of a sudden, or worships badly in the spring, there are often voles at work. Typical mark: The roses are easily pulled out of the ground and the roots are eaten. You do not have to throw away the plant yet: Cut the root remnants with the scissors and put the plant back in another place protected by a wire basket. As she drives out, she usually recovers. New roses should then be planted together with a wire basket from the beginning.
4. properly mulking roses helps against star soot
After the spring cut, the area around the root ball should always be covered with a mulch layer. Initially, grass clippings (mixed with stinging nettles and horsetail) are suitable, because then the nitrogen content may be very high. From June you can use better cut fern leaves, tagetes and marigolds. Bark mulch like roses less, it makes the soil sour and deprives him too much nitrogen. Before mulching in the spring you should remove old, fallen leaves on which fungal spores from the previous year often overwinter.
Especially freshly planted roses are grateful for a mulch cover in the first year
5. Herbal extracts as a tonic
Pest infestations and diseases such as blackspot can be prevented with organic herbal tonic. These agents promote rooting and shoot growth. More vigorous plants are not only more resistant to disease, they can also recover faster from an infestation. Depending on availability, you can chop thyme, chamomile, tagetes, garlic, stinging nettle, tansy and feverfew and pour boiling water over them. This plant manure is used for pouring the next day. To prepare a herbal slurry, add dandelion, yarrow, elderberry leaves and onion peels and allow to ferment every two weeks. You can use the manure diluted 1:10 with water as a spray or fertilizer. Also spread the sifted plant residue around the diseased roses.
Alternatively, you can also use ready-made tonics from the specialist market. Here the dried herbs are already mixed and dosed as pads - they only have to be added with water. Then you can spray the preparation either as an extract, tea or broth directly on leaves and shoots or pour the rose with the manure. If the effort is too great to handle the pads, you can also buy the preparations as a ready-to-use product in the spray bottle. With this then the entire plant is sprayed every seven to ten days. Only wet shoots and leaves and save buds and flowers as much as possible.
6. Stinging nettle strengthens the body's defenses
Stinging nettle is an ideal fertilizer and strengthens the plant's defenses. About one kilogram of nettles (ideally only the leaves) are cut and placed in a container with 10 liters of rainwater in a warm, sunny place. Rock flour reduces the unpleasant odor. When the broth stops foaming and has a dark color, it is ready; then sieve.As a weekly fertilizer, the slurry is diluted 1:10 with water (use only until flowering). For spraying, slurry is used before fermentation (before it foams) and lightly diluted every three weeks with overcast skies over the roses.
The fertilization of roses with homemade nettles should not take place later than the end of June
7. Garlic helps against leaf fungi
When the rose cut is completed in the spring, spraying of shoots, leaves and soil with garlic broth prevents infestation by fungi such as mildew, blackspot and rose rust. Crush roughly 20 cloves of garlic, boil in a liter of water and cover for 15 minutes. The brew is allowed to stand for seven and 24 hours. Dilute (with water 1:10) from May three times at intervals of three days spray. Incidentally, cloves of garlic planted in the ground should intensify the scent of roses.
8. Tonic for more vitality
In addition to a sunny, airy location, the soil is crucial for the health of roses. Natural soil additives with so-called mycorrhizal fungi and organic stimulants improve the soil climate, make roses grow better and facilitate nutrient absorption. Tonics such as Vitanal, a biological agent of cereals, promote soil life, rooting and shoot growth.
Ladybugs are the natural enemies of the aphids
9. Beat aphids
Aphids on rosebuds are a common sight that usually only pleases birds and ladybirds. These beneficials reduce the infestation in a natural way. In addition, one can spray away the aphids with a sharp jet of water. Also nettle tea is to help against the vegetable juice suckers: cut nettle leaves, pour over boiling water, let stand overnight and sift. Pour the tea over the shoot tips of roses and other plants.
10. Tansy sells weevil larvae
It is not the weeping weevil itself, but its larvae that are the most troublesome to our roses. As for voles, their roots are a delicacy - the plants wither in a short time. The larvae hatched from August can be combated with tansy broth, which is poured several times around the infested roses, as well as with nematodes. The adult beetles are barely visible during the day, but their feeding marks on the leaves are unerring: Round bulges on the leaf margins can be found not only in roses, but often in rhododendrons. The nocturnal beetle can be picked up in the dark with a flashlight or shaken off in the morning hours and collected with lined cloths.
