Best way to prune Osteospermum?

abufish(z10 CA)October 26, 2011

We just moved in a new place where lots of Osteospermum are growing on a slope. It probably has been a while since they last cut it and it gets really thick and woody. Gray stems can be seen anywhere and some longer stems are more than 8 ft long!

I'm looking for a way to prune them (cut them back). I read online that you can mow them? That's probably hard since the slope is almost 45 degree and some stems are really thick (half inch). Or should I just remove them and plant something new altogether?

Any suggestion is appreciated!

Good things about Osteo: Need almost no maintenance, water need is minimal, flowers are pretty dazzling in a mass. Controls erosion on a slope.

Bad things about Osteo: Can grow out of bounds and can look poor out of flower.

There's a reason this plant is used on freeway plantings and slopes (see good things above).

If you want to freshen it up, just use a straight shovel and chop out parts. It is easy to remove part or all of it.

Whether you want to replace it is up to you really.

Thank you! Looks we will have to replace them altogether.

Is Myoporum a good substitute? Or Gazania? We need a groundcover that's low growing, drought tolerant, half-sun, do not attract bees (like Aptenia) and rodents (there were lots of grains under osteo, I'm suspecting some little animal made it their home before).
