During the winter months we can cover a portion of the soil near the roots with dry leaves or other mulch tissue; in this manner we will protect the plant from the harsh climate. For a balanced development of the the Oleander it is advisable to locate it in a place where it is exposed to at least a few hours of direct sunlight.During the spring the the Oleander can't stand the cold weather; should the climate be particularly harsh, with minimum night-time temperatures some degrees below zero, let's cover our plant with non-woven fabric.
Letís remember to fertilize our shrubs often; we can fertilize enriching our soil with manure, at the end of the winter; or we can give it a fertilizer for flowering plants, every 20-25 days, when watering. If the shrubs are large or cover a large area, we can use a slow release granular fertilizer, to be used every 3-4 months. In the spring letís favour fertilizers rich in nitrogen and potassium, to favour the development of a new vegetation and of flowerings.
Growing they develop a round-shape shrub. The Oleander develops like a shrub. This plant in the spring assumes a pink colouring; it is medium in size and can reach 4 m high. It keeps its leaves in the winter.
Letís water these plants only when the substratum is clearly dry using 1-2 buckets of water ; during this period of the year we should intervene every 2-3 weeks , or even less if the weather is rainy. Concerning those specimens grown in vases, let's remember that usually they need more watering, compared to the same shrubs placed in the ground. Moreover, they are often more sensible to temperatures, either very high or very low, and to radical apparatus diseases.
The spring weather, with a high temperature swing between the day and night hours, and pretty frequent rains, can favour the development of fungus diseases, which should be treated pre-emptively with a systemic fungicide, to use before the gems grow excessively; at the end of the winter we also suggest a wide range insecticide to prevent the attack of aphids and cochineals. We should always remember to do these treatments when there aren't flowerings in the garden.
These shrubs favour a soft and deep, but well drained soil.
