With their cheerful daisy-like blooms in shades of orange yellow, pink, and white African daisies (Osteospermum species) are a favorite for gardens, containers, and landscapes. To keep these beauties looking their best and flowering prolifically, it’s important to know how to properly prune African daisy plants.
Proper pruning encourages bushy, compact growth and stimulates abundant blooms throughout the growing season. Here’s a complete guide to pruning African daisies for optimal health and performance.
When to Prune African Daisies
Pruning African daisies should be done at three key times:
- Early in the growing season
- During midsummer
- At the end of the season
Here’s a closer look at when and why to prune at each stage.
Early Season Pruning
In early spring or when new growth first emerges use your fingers to pinch or snip off the top couple sets of leaves on each stem. This encourages the plant to branch out rather than stretch upward creating a fuller, bushier shape.
Pinching back the tips also delays flowering, which is beneficial because the plant will be better established before putting energy into blooms.
Midsummer Pruning
After the initial spring flush of flowers, prune African daisies again in midsummer. This helps rejuvenate the plant after the first round of blooms. Cut each stem back by about one-half its length. Be sure to leave at least 2-3 sets of leaves on each stem.
Midsummer pruning removes old flowering stems and stimulates the development of fresh new growth. The plant will reward you with abundant new blooms 4-6 weeks after pruning.
End of Season Pruning
At the end of the growing season, pruning requirements depend on whether you are growing African daisies as annuals or perennials.
For annual African daisies, pruning isn’t needed. Simply pull up and compost the plants after they die back with the first fall frost.
If you are overwintering African daisies as perennials in zones 9-11, prune back the plants by about one-third in fall. This removes old, woody growth and encourages the development of new growth and blooms the following season.
Deadheading for Continual Blooms
In addition to scheduled pruning sessions, be diligent about deadheading spent African daisy blooms throughout the season. Deadheading prevents the plant from setting seed and redirects its energy into producing more flowers.
To deadhead, use pruners or your fingers to snip or pinch off spent blooms just above a set of healthy leaves. Make deadheading a part of your regular garden maintenance for non-stop flowers.
Pruning Perennial African Daisies
African daisies perform best when grown as annuals in most regions, but they can be overwintered as perennials in zones 9-11. Here are some tips for pruning perennial African daisies:
-
Cut plants back by one-third to one-half in late fall before first frost.
-
Prune lightly again in early spring to shape the plant and remove any dead or damaged growth.
-
Prune repeatedly to control size and create a rounded, mounded form. African daisies can become large and woody without proper pruning.
-
Take stem cuttings in summer to propagate new plants. This allows you to replace aging plants as needed.
-
Divide congested clumps every 2-3 years to rejuvenate the planting.
Signs It’s Time to Prune
Watch for these signs that African daisies need some pruning TLC:
-
Plants are getting tall, leggy, and uneven in shape.
-
Leaves and flowers are smaller than normal.
-
Blooming slows down or stops altogether.
-
Old woody stems predominate with few new shoots.
-
Brown leaves and dead stems give the plant an unkempt appearance.
When you notice any of these issues, it’s time to do some judicious pruning!
What You’ll Need
Pruning African daisies is simple and requires just a few basic tools:
- Bypass pruners or gardening scissors/shears
- Small knife or razor blade (for stem cuttings)
- Clean plastic pots or trays (for rooting cuttings)
- Rooting hormone powder (optional)
- Seed starting mix or perlite (for rooting cuttings)
Use clean, sharp pruning tools to make cuts. Disinfect tools periodically with isopropyl alcohol to prevent the spread of disease.
Step-By-Step Pruning Instructions
Here is a simple step-by-step guide to pruning African daisies:
Spring Pruning
-
In early spring, use your fingers or pruners to pinch off the top few sets of leaves on each stem. This encourages lateral branching and a bushy, compact shape.
-
Be careful not pinch off more than 30%-50% of the total plant height. Leave several sets of leaves on each stem.
-
Make additional pinching/pruning passes every 2-3 weeks until flower buds start to form.
Midsummer Pruning
-
In midsummer, use bypass pruners to cut back each stem by about one-half its length.
-
Cut just above a set of healthy leaves to allow new shoots to develop.
-
Remove and discard any dead or damaged stems down to the base of the plant.
-
Pruning stimulates new growth – expect fresh blooms in 4-6 weeks.
Fall Pruning
-
In fall, prune tender perennial African daisies back by one-third to one-half before the first frost.
-
Cutting back removes old woody stems and makes room for new growth.
-
Leave the rest of the plant intact to help insulate roots over winter.
Deadheading
-
Check plants frequently for spent blooms.
-
Use finger pinching or pruners to snip off dead flowers just above a set of healthy leaves.
-
Consistent deadheading redirects energy into new blooms vs. seed production.
Pruning Tips and Precautions
Follow these tips to get the most out of pruning African daisies:
-
Always make cuts just above a leaf node to avoid leaving bare stems.
-
Disinfect tools before each pruning session to prevent disease transmission.
-
Remove all dead, damaged, or crossing stems down to the base.
-
Water and fertilize after pruning to encourage rapid regrowth.
-
Wear gloves and long sleeves – some African daisies have irritating sap.
-
Avoid overpruning, especially in hot climates, as too much stress can kill the plant.
-
Prune in morning or evening to avoid pruning during the heat of the day.
Alternatives to Pruning
If you have trouble keeping up with frequent pruning, consider planting African daisies in a site with full sun and excellent air circulation. These conditions encourage short, compact growth. Avoid overly fertile soils which promote tall, lanky plants.
Another option is to grow new African daisies from stem cuttings each year. Taking cuttings annually provides vigorous new plants that don’t require extensive rejuvenation pruning.
Key Takeaways
Here are the key points to remember about pruning African daisies:
-
Pinching back tips promotes bushy, branching growth. Do this in early spring.
-
Midsummer pruning rejuvenates plants after initial flowering. Cut stems back by one-half.
-
Prune tender perennials lightly in fall and again in early spring.
-
Deadhead consistently to maximize blooms.
-
Disinfect tools before pruning to prevent disease spread.
-
Prune in morning or evening to avoid heat stress.
-
Consider annual propagation if frequent pruning is difficult.
With the right pruning approach, African daisies will reward you with months of vibrant, colorful blooms and an attractive, rounded shape all season long. Happy gardening!
When to Prune African Daisy
You can prune African Daisies as early as the spring, when the new 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. Pinch plants early in the summer to clean them up after the first flowers have died off. African Daisies will grow back stronger if you cut them in half. In four to five weeks, they will bloom again.
Deadheading is a technique that extends the blooming period. Regularly cutting out the spent flowers will keep the plant from setting seed early in the summer. Continue to deadhead African Daisies all summer. When it gets hot in the middle of summer, African Daisy plants that are grown as perennials will slow down their growth.
If you keep watering and fertilizing the plants, they will bloom again when the weather cools down in the late summer. Continue deadheading spent flowers through the fall. In the early spring, new growth will begin. So that the African Daisy grows bushy, now is the time to cut back hard on the bottom growth.
Why Prune African Daisy
Pruning, deadheading, and pinching of African Daisy keep the plant compact and blooming throughout the primary growing season. For African Daisies that are grown as perennials in warmer places, not deadheading them regularly can make them woody and leggy. This tender perennial is also not very long-lived compared to more hardy perennials.
Taking cuttings from softwood growth can provide replacement plants for when the main plant dies. At the height of summer, cut nonflowering stems to 6 inches. Remove half of the foliage and place the cutting in a pot of seed-starting mix or perlite. Keep the pot watered well until new foliage growth appears. This will let you know the cutting has rooted and can be potted on.
