Roses are probably one of the most beautiful garden plants. Unfortunately, they are often affected by powdery mildew and other diseases. Treat fungal diseases and pests with horsetail broth. The wild herb is ideal for roses to strengthen the leaves of the ornamental plant.
How does horsetail help roses?
Horsetail is ideal for roses to strengthen their leaves. A homemade horsetail broth can be used for acute mildew or other fungal diseases and can be applied once a week for prevention. Horsetail manure serves as a biological fertilizer.
Use horsetail broth against mildew
The gardener does not consider horsetail to be one of his favorite plants. However, the herb does a good job when caring for roses.
In addition to tannins and essential oils, it contains a lot of silica, which is effective against fungal diseases such as powdery mildew on roses.
The rose petals are sprayed with a broth of horsetail when an infestation occurs. Box broth for roses is also suitable for prevention.
Make your own horsetail broth
You can easily make horsetail broth yourself. To do this you need:
- Plastic jar
- fresh or dried horsetail herb
- Rainwater or tap water
sieve
Put 200 grams of fresh or 15 grams of dried herb in the container and preferably pour rainwater over it. Let the mixture steep for 24 hours.
Then the broth is boiled. It takes about half an hour for the silica to dissolve from the leaves. The broth must then be cooled and finally diluted 1:4 with fresh water.
Treating roses with horsetail broth
In case of acute fungal infestation, spray the leaves with the broth several times a day.
Field horsetail is also ideal for prevention. The silica strengthens the leaves so that fungi and pests cannot penetrate.
For prevention, treat the roses with horsetail broth once a week.
Fertilize roses organically with horsetail manure
Horsetail manure is prepared in a similar way to broth, except that the herb is left in the water for a longer period of time and is not boiled. The manure is ripe when no more bubbles appear.
The manure is diluted with water in a ratio of 1:5 and watered around the roses once a month. Make sure that you do not pour the manure directly onto leaves and roots.
The minerals strengthen the plant. The leaves appear he althier and there are usually more flowers.
Tip
Horsetail broth also helps against numerous pests. Spray the roses if aphids or spider mites have attacked the leaves.
