- When planting choose a well drained soil and a position in full sun to afternoon shade.
- Dig in some well rotted compost before planting.
- Water in with a liquid seaweed fertilizer.
- Provide moisture through the first summer until the root system is established.
- Apply a slow release fertilizer every 2 – 3 years.
- Mulch around plants in spring to maintain a cool root run.
As Abelias can become a little leggy over time they will require pruning, this will also force new growth that will produce more flowers for the next season.
It is tempting to just get out the shears and prune them back to size, however this can cause a few problems.
You are best not to shear them back to ball shape as this causes die back and it will also cause water shoots. So you will have long shoots coming from a ball of foliage. Not the best look for an Abelia.
Look for the longest stems and cut them back to the ground to help reduce the size, however you can still get long water shoots. You just need to wait until they settle in.
You can remove the longer branches that touch the ground and then some of the longer curved branches. The best time to prune is in summer right after flowering.
You can give older plants a new lease of life by hard pruning, this is best done early in the growing season, in spring as soon as new growth commences.
The easiest way to prune these shrubs is to hard prune them every 4 – 5 years.
