At the arrival of autumn, as soon as the temperatures drop, the problem is the same every year: and now how do we do with that orange plant that we bought in the nursery this summer?
All gardening enthusiasts, at least once in their life (perhaps even more often) have dared to buy seeds, cuttings, plants, shrubs of tropical, exotic, particular origin, which will surely perish in the winter climate of the Po Valley; often it also happens that the fashion of the moment brings many gardening enthusiasts to plant the shrub of the year in the garden, what can not miss in the mixed border, what the June magazine recommended, what makes those flowers incredible.
A classic example in recent years is the grevillea, which has found its place in many gardens, given the beauty of flowers and fronds; only that some species of grevillea endure short frosts, nothing more, and when the frost arrives they will almost certainly be damaged in the Trento garden constantly blown by the wind.
So what to do?
Fortunately, there are several methods that allow us to grow exotic plants even in Milan, without necessarily having to build a huge greenhouse to contain them.
The terrace: an unsuspected resource
Often we do not think about it, but our terraces can become an excellent shelter for pot plants that are not completely rustic: geraniums, exotic plants, small shrubs that are frost-sensitive. These plants can be sheltered simply by being moved to the shelter of the terrace.
Clear, the terrace should be exposed to the sun, to the east or south, so as to enjoy the refreshment of direct sun for most of the day.
We place the pots to be repaired near the wall of the house, rather than near the edge of the terrace, this to benefit more from the shelter guaranteed by the house itself, which functions as a windbreak and allows our plants not to be affected by frost.
If we still fear that the cold is excessive, or that the plants are too delicate, let's cover them with non-woven fabric, which will help raise the minimum temperature near the leaves by a couple of degrees.
