For the plant care there are natural medicines, that is substances obtained from other plants that you can prepare yourself and administer in the form of macerates and infusions. We start from these and only if the case requires it, but then it must be a very serious attack (such as the boxwood defoliator caterpillar) we move on to chemical systems.
Most of the time natural medicines work well for plant care in the acute phase of the most common diseases (white sore, lice, spider mites, downy mildew ...) but the ideal is to use them as a prevention as well. Since these are natural preparations well tolerated by plants (in the right doses and except for specific contraindications), scheduled treatments can be carried out in the periods of greatest virulence of infections to have a perfectly healthy garden and vegetable garden. The costs are very low because you can get everything you need yourself, the only real commitment is work. Why, it must be said, in the plant care with natural remedies it takes a lot of work.
Of wild herbs and medicinal plants easy to use for plant care there are several. The most common are: nettle, tansy, garlic, horsetail, wormwood, onion, chamomile, comfrey, shepherd's purse, dandelion, chives, fern, marjoram and mint. Keep them in mind when designing your vegetable garden and garden.
It is good to always leave a space in the garden or vegetable garden where a little nettles can grow. With fresh leaves and stems left to soak in cold water for a few days, the nettle macerate is prepared, which is an excellent prevention because it fortifies the plants making them more resistant to parasites such as spider mites.
Decoction of tansy
Excellent against attacks by aphids and plant lice, the decoction of tansy has the advantage of not being phytotoxic and can be used in repeated treatments. Tansy is easy to find on roadsides or in fields, and tansy (or tea) decoction is easy to make. It is effective for fighting aphids and lice.
Infusion (or decoction) of garlic
Garlic is the oldest natural medicine in the world and not just for plant care. The garlic infusion is prepared by boiling the cloves and letting them macerate for 24 hours. It is especially effective against white disease (powdery mildew) which is one of the most common plant diseases.
Horsetail is rich in salicylic acid, which is so called because it is contained in large quantities in the willow bark (which, however, is more difficult to find than horsetail) and is used in pharmacies for skin care. The horsetail decoction is prepared like that of tansy and is effective against mycosis because it strengthens the plants making them more resistant to the penetration of fungi.
To recap, here is a mini handbook for the plant care against the most common infections:
- Programmed prevention and red spider mite: nettle macerate;
- Aphids and lice: decoction of tansy;
- Mal bianco: decoction of garlic;
- Fungal diseases: horsetail decoction.
With absinthe, onion, chamomile, fern, comfrey, shepherd's purse, dandelion, chives, marjoram and mint, other fortifying macerates and decoctions can be prepared, which can be mixed with nettle macerate for an even better effect.
