How to cut back agapanthus?

The best time to prune agapanthus is right after the flowers have finished blooming, which is usually in the summer and fall. When you're ready to prune, simply snip the flower stalks right at the base of the plant.

When you're thinking about pruning your agapanthus, the best time to do it is right after it stops blooming. For most plants, that's usually in late summer or the start of fall.

If you're not too bothered by their appearance, you can always snip them right back in the early spring. And if you have any dead leaves at the base, you can gently remove them by hand. Cut back deciduous agapanthus to about 4 inches (10 cm) above the ground for best results. The green leaves can stay as they are, but if you prune them, remove any dead, damaged, or unsightly shoots.
