Plumbago hedge

Question: Plumbago hedge

I wanted to cover my fence with plumbago plants to get a sort of hedge.
Better to fix them on the net or make them grow as a bush?
How much distance should I leave between one plant and another so that it compacts over time?

Answer: Plumbago hedge

Dear Roberto,
the plumbago capensis is a shrub native to southern Africa; it produces long stems, which tend to make the plant quite messy, and often it is grown as a creeper, but since the stems have no method of attaching to a trellis, it is necessary to periodically attach some, in order to invite the plant to develop in height. Whether to keep it free, or tie it to a trellis, depends on you, on how you prefer it to grow, and on the needs you have: consider that if you cover a fence you will be forced to tie it to the supports, if instead you just need a low shrub, you can leave it develop freely, to obtain a sort of fountain-like shrub, large and dense. Plumbagos are also often used as hanging plants. These plants are native to southern Africa, and their development depends fundamentally on the climate, and on how much space the roots find to develop. If you live in an area with very mild winters, with minimum temperatures that are unlikely to drop below 5-10 ° C, then you can place your plumbago in full ground, where they will have a very wide development, and then you can place them at about a meter, or even a meter and a half away: within a few years you will find yourself with a wall of leaves and flowers. If instead in the area where you live the climate tends to become very rigid in winter, then your plants will be cultivated in pots, so as to move them to the greenhouse, or near the house wall, when the harsh climate arrives; in this case, being able to obtain the coverage of a fence will be a bit difficult, also because, in case of intense cold, you will have to move the vessels, cutting off part of the branches. It also considers that, although they are evergreen plants, when the climate becomes excessively cold, the plumbagos tend to lose much of the foliage, which will then return in late spring. In any case, it finds a very sunny position, and uses a very well drained soil, because the plumbago does not like water stagnation, and if positioned in excessively shaded areas it tends not to produce flowering. During the winter months, it is convenient to cover the base of the plants, with mulching products, such as barks or straw, so as to prevent the soil from cooling off excessively.
