Plumbago grown in pots
It is advised to plant your plumbago in good flower plant soil mix.

Caring for plumbago
It isn’t really a requirement to prune.
Annual pruning is eventually possible at the end of winter or at the beginning of spring, proceed lightly in order to stimulate the blooming and preserve the shape.
Plumbago, apart from watering after planting, will need a lot of water when the weather is hot, especially if grown in a pot.
- Water regularly, but not too much, from May to September.
- Reduce the watering in water.
- In spring and summer, take the time to add a little flower plant fertilizer every now and then.
For the best growth and an abundant blooming, add flower plant fertilizer or shrub fertilizer every two weeks in spring and summer.
Stop adding fertilizer as soon as your plumbago has stopped blooming.

You can set it up in your garden if the climate is mild enough. Double-check that this is possible, because plumbago is vulnerable to frost and will suffer if temperatures drop below 32°F (0°C).
But it is particularly well-suited to growing in pots, which will make it easy to bring them indoors to a cool spot that is sheltered from the harshest colds over winter.
Lastly, if you wish to train it into a climbing vine, you can attach it to a lattice because it won’t cling to the wall on its own.
In our latitudes, when grown in a pot, a plumbago plant can reach anywhere from 3 to 6 ½ feet (1 to 2 m), whereas it easily rises to 13 to 17 feet (4 to 5 m) in its natural environment.
