Wintering your cactii
It is necessary in winter unless you have the good luck to live in the extreme south of France, to bring your cactii and other succulent plants indoors. Their morphology is adapted to dry conditions and allows them to store a lot of liquid. The liquid stored can be up to 50 to 80% of the weight of the plant! The stored liquid is essential for the survival of the plant in extreme weather conditions and renders it even more sensitive to frost.
Cleaning before wintering
From the first sign of autumn chill, stop watering and fertilizing the cactii immediately. Verify each pot to check that there are no parasites on the plants. Look closely around the collar and under the plant to check that there are no scale insects present. Signs of their presence are whitish traces in the form of small concentric circles resembling cotton! Take the time (and patience !) to remove them by hand one by one using a solution of alcohol and oil.
Check that there are no brown stains on your plants. If this is the case on plants with a cylindrical form, treat them with a product which fights against cryptogamic diseases and isolates them.
If blackish stains appear on the leaves of your agaves this means that they contain too much water. Cut the leaves affected, leaving just the “head” if necessary, treat them and keep them in a dry place. ( click next button for the preview next page)
