Sharing is caring!

If you want to keep your gorgeous flowers blooming all summer, take time to learn how to deadhead African daisies properly. Deadheading Osteospermum (scientific name) is quick and easy when you make time for it!

At a greenhouse earlier in June, my youngest daughter and I fell in love with some pinkish purple and orange African daisies, scientifically known as Osteospermum. Originally, I picked up one pot of flowers, but my daughter insisted we needed two.

Right now, I have one African daisy planted in the garden and the other in a pot. Both were doing great, until I didn’t deadhead them.

They all but stopped blooming!

To remedy this, I took my snips outside and cut away the deadheads. Now, new flower buds are emerging and ready to take center stage.

How long do African daisies bloom?

Depending on your location, African daisies bloom from late spring through the fall. Hardy in zones 10-11, they are treated as annuals in northern zones. In the extreme summer heat, Osteospermum may take a break from blooming and resume when the cooler fall temperatures arrive.

Like other daisies, these can bloom for quite some time.

Try these simple steps for pruning and deadheading African daisies:

  1. Once you find a dead flower, hold the stem between your forefinger and thumb of your nondominant hand.
  2. Use sharp, clean scissors to cut the flower stem below the deadhead.
  3. Set aside the deadheads to go out with your yard waste.
  4. Continue snipping away all Osteospermum deadheads in this manner.
  5. Once done, examine the plant.
  6. If desired and no fresh, new growth is showing on the long stems, you may now snip down those stems to even out the plant. Simply cut the stems lower, beneath a few leaf sets, to elevate the new buds to the forefront.

When pruning African daisies, use care not to snip away stems with buds.

Pruning osteospermum isn’t always necessary, but it can be a matter of preference. Shape your plant to your own liking!

African Daisies Not Blooming

If you find your African daisies stopped blooming, take a look at the plants. Are the Osteospermum deadheads still attached?

When you find African daisies not blooming, it’s usually time to take out the snips and remove any spent blooms.

Follow up with a nice watering with a little fertilizer if you haven’t fertilized your African daisies recently.

Pruning for Aesthetics

In my opinion, deadheading osteospermum is so much like pruning. Once I started removing African daisy deadheads, I found the plant didn’t look as attractive as I’d hoped.

Too many little green stems stuck up every which way!

To fix this, I set about pruning African daisies as part of the process. After snipping off the deadheads, I cut back the individual stems so that the stems with buds had more prominent placement.
