Little things at hand
Garlic - For large plants (cherry, apricot, peach, etc. ..) - Insects, aphids, ants -
A natural way, not harmful to the environment, effective and invigorating to plants to which it is addressed, and especially suitable for removing insects from diseased plants. Personally, I tried it on a cherry tree and within two weeks parasites are gone.
It is enough to bury around the plant to be treated, spaced about 40 cm from the trunk, a dozen cloves of garlic sprouts, soon to be themselves seedlings. The roots of the infested plant will absorb the mood of garlic and this will begin to flow in the lymph of the same, resulting in a short time, a disinfectant, all insects away naturally. Garlic is also a natural antibiotic, for bacterian deseases.
Tobacco - For every plants indoor also -
Soak in the water a few cigarette butts, smoked, for at least one night, after which it is filtered everything and you put obtained water in a spray. We can then go spraying of diseased leaves with this water, preferably in the morning, and let it carries on its activities throughout the day. In the evening it is better to rinse the leaves with clean water, to avoid the effect of tobacco burned damaged in some way the plant. Within a few days the effects should be visible.
Another method similar is to macerate for a night and the quantity of tobacco of three cigarettes in half a liter of water with the addition of three garlic cloves squeezed. The next day everything is filtered and poured into a sprayer that you're going to wet the leaves of plants attacked by aphids or other insects. In this case serves no rinse, since the compound obtained is not harmful to the plant.
Lemon - For every plant, large or small, indoor or outdoor, environnement and lawn - (in particular ants)
Cut one or more lemons in half. Let them do their green mold. Place the half rotten lemons on the base of plants and paths of the ants. Renew them when too old.
Nettle - For every plant - Aphyds -
Decoction of nettles. You put abundant doses of nettle leaves in cold water, boil and when it comes to a boil turn off and allow to cool. Then you drain and use treated water on the plants.
All those methods I use normally and find a very good result.
