Osteospermum boasts beautiful daisy-like flowers in a variety of different colours, earning it the nickname African daisy.
Its long-lasting blooms and relative hardiness make it an ideal choice of perennial plant for British beds and borders.
Though the plant will flower reliably even in poorer quality soil and when left to its own devices, you can extend its blooming season and ensure it retains an aesthetically pleasing shape by pruning it regularly.
African daisies, also known by their botanical name Osteospermum, are stunning bloomers that can brighten up any garden with their vibrant colors To keep your African daisies looking their best, proper pruning is essential The right trimming practices will promote healthy new growth, enhance flowering, and maintain the plant’s aesthetics.
In this extensive pruning guide, we will cover everything you need to know about trimming African daisy flowers successfully.
Why Pruning is Crucial for African Daisies
Here are some of the key reasons careful pruning is vital for African daisies:
-
Encourages new growth – Trimming stimulates the plant to produce fresh foliage and stems, leading to a fuller, bushier appearance.
-
Prolongs blooming – Deadheading spent blooms prompts continued flowering throughout the season
-
Improves air circulation – Removing crowded, crossing branches prevents fungal diseases.
-
Maintains shape – Pruning controls size and form for visual appeal.
-
Enhances health – Eliminating dead material wards off pests and infections.
When to Trim Your African Daisies
The optimal time for pruning African daisies is early spring before growth resumes. However, light grooming can be performed as needed during the growing season to tidy up the plant. Avoid heavy pruning in summer when plants are actively growing.
Helpful Tools for Trimming African Daisies
Arm yourself with these essential tools before pruning African daisies:
-
Sharp bypass pruners sterilized in diluted bleach to prevent disease transmission.
-
Gardening gloves for protection from thorns and irritants.
-
A small gardening fork for loosening soil.
-
Compost or burlap to gather trimmings for disposal.
Step-by-Step Guide to Pruning African Daisies
Follow these simple steps for grooming your African daisies successfully:
1. Remove Dead Growth
Examine plants and use pruners to cut away any dead or diseased stems, leaves, and spent flowers down to the base. This tidy up improves air circulation and appearance.
2. Shape and Thin Plants
If plants are leggy or overgrown, cut back stems above a leaf node to encourage branching and a compact form. Also, thin crowded areas to prevent fungal issues.
3. Pinch Off First Flower Buds
Pinching back the initial round of buds signals the plant to generate more blooms for an extended flowering period. Pinch just above a set of leaves.
4. Deadhead Faded Blooms
Snap off or snip away spent flowers through the season to maintain flowering. Cut back to a leaf node.
5. Cut Back Old Growth in Spring
In early spring, use pruners to cut each stem down to approximately one-third its size. This rejuvenates growth.
6. Water and Fertilize Lightly
After major pruning, water well and apply a diluted balanced fertilizer to nourish the plant. But go easy on fertilizer to avoid excessive growth.
Tips for Successful African Daisy Pruning
Follow these tips for the best results when pruning your African daisies:
-
Disinfect tools before each pruning session to prevent disease spread.
-
Avoid removing more than one-third of the plant’s foliage at once to prevent stress.
-
Prune lightly and gradually rather than all at once for a gentle approach.
-
Use a sterile pruning paste on cuts over 1 inch across to prevent infection.
-
Water after pruning to aid recovery from the stress of trimming.
-
Apply an organic mulch around plants after major pruning to conserve moisture.

Overgrown, uncontrolled shape
By learning when and how to properly trim your African daisies using this comprehensive guide, you can help keep your plants healthy and flowering beautifully season after season. Proper pruning is truly vital for the best performance of these gorgeous bloomers.
Cut Back In Late Spring Or Autumn
In order to maintain an aesthetically pleasing structure for your osteospermum’s growth, you should cut it back in late spring.
Use the shears to cut back the plant to at least half its original height, taking care to leave several leaf clusters on each stem.
Remove all cut foliage and dispose of it away from the plant to prevent the spread of disease.
You may repeat the process in autumn if you wish to instigate fuller growth.
When To Prune
It’s advisable to cut back your osteospermum plant in early spring or autumn, or even at both times if you wish to encourage fuller growth.
However, doing so on at least one occasion is imperative in preventing your plant from becoming overly tall and leggy.
It’s also a good idea to deadhead your African daisy throughout the blooming season since this will divert its energies away from seed production towards blossoming.
It’s vital that you ensure the tools you use are free from blight or disease.
As such, you must clean them thoroughly before and after use each time.
To do so, soak a cloth in isopropyl alcohol and rub the blades of your pruning shears to remove any impurities.
“It’s important to keep secateurs and shears clean by removing resin on a regular basis using a proprietary resin remover or cleaning eraser, and to keep them sharp using sharpening tools designed for this task,” says Master Horticulturist Roy Nicol.
“This will ensure clean cuts which will heal more readily – much better for the health of the plant.”

How do you prune African daisies?
The pruning of African Daisies starts early in the growing season while the first leaves and stems are still small. Pinching out the top growth and first flower buds will encourage branching further down the stem. The result will be a much more compact plant with many more blooms and sturdier stems.
Do African daisies need to be cut back?
The result will be a much more compact plant with many more blooms and sturdier stems. Pinching is done early in the summer to tidy the plants after the first flush of flowers has faded. Cut African Daisies back by half to rejuvenate the plant and encourage another round of blooms in 4-5 weeks.
When should you trim African daisies?
The trim will stimulate the growth of fresh, new foliage. If you live in USDA plant hardiness zone 9 or above, perennial African daisies benefit from annual pruning. Cut the plant to the ground in late fall or early spring. Either time is acceptable, but if you are set on a tidy garden going into winter, you may want to prune in autumn.
How do you prune a daisy plant?
Prune your daisy up to 3 inches tall in early spring before new leaves sprout. This helps the plant to focus on new growth. Cut off wilting, dying, and dead flowers, known as deadheading, when the flowers are growing throughout the blooming season. From spring to fall is the blooming season. By doing this, you encourage the new growth of flowers.
