The Convolvolus sabatius can't stand temperatures below zero; they should be grown in cold green houses or at least in a place where they are sheltered by the wind; when every risk of late freezings has gone by we can place them outside or remove the protections. These plants lose the aerial part during the coldest months of the year. As spring begins, stems and leaves quickly start to reproduce.The Convolvolus sabatius should be grown in a bright place, with direct sunlight.

We suggest adding to the irrigation water, in the spring, every 20-25 days, a specific fertilizer for flowering plants. We can also mix to the soil near the plants a granular slow release fertilizer, which has a 3-4 month action.
Watering Convolvolus sabatius
Water rarely, about once every 1-2 weeks with 2-3 glasses of water , keeping the soil dry for a few days before watering again; when wetting we suggest avoiding surpluses, however to wet the soil deep down. Perennial plants are subject to some months of vegetational rest. During these months it isn't necessary to water them.

Generally during this time of year we suggest a pre-emptive treatment with wide range insecticide and with a systemic fungicide, to prevent the attack from part of the aphids and the development of fungus diseases, often favoured by a mild and damp climate.
