For a neat African daisy garden, you need to prune the flowers, which should be done in the following seasons

Prune In Spring

Prune your daisy up to 3 inches tall in early spring before new leaves sprout. This helps the plant to focus on new growth. 

Prune Between Spring And Fall

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. 

Prune During Summer

During mid-summer, the daisy flower becomes long and leggy. This causes them to become floppy and fall over.

When this happens, fewer flowers are produced. The lack of a thick bush full of flowers can make your garden appear untidy, and this is not what you want.

You should cut the flower stems in half to encourage new blossoms. Doing this assists the side shoots growing from the stems, making the plant bushy and thick, with new leaves and flowers.

Your daisies will look neat throughout the summer. Don’t forget to water and fertilize your plants frequently during this season. It keeps them blooming throughout summer.

Improve Growth In Summer And Spring

Pruning encourages the growth of your daisies in spring and summer. The steps below will guide you in the process: 

Cut Off Dead Flowers

At the start of spring, cut off any dead, wilting flowers using a pair of hand pruners. You can also use your fingers.

Cutting off dead flowers prevents them from producing seeds, which could lead to the growth of unhealthy flowers. This means that you'll leave the healthy flowers to grow.

Cut Back All The Stems 

After cutting the flowers, cut off all dead stems and leaves that are brittle and black or dark brown. If you notice yellow stems and leaves, prune them as well. The best length to cut back these stems is 4 inches. 

Leave The Flower Buds Intact

As you are pruning the flowers and stems, do not cut off the flower buds that grow 5 inches below the large flowers. These tiny flower buds are ¼ inch in length. 

Wait For Flowers To Grow

After pruning, you'll notice how fast your daisy flowers will grow in two to three weeks. If you don’t prune, your garden will have unattractive flowers. 

Repeat Pruning

Repeat the pruning cycle in each growing season. As mentioned earlier, you should prune when the daisies are wilting and dying and when they begin to produce seed. 

Pruning essentially cuts short the reproductive cycle of the flower. It forces the reproductive cycle to begin again.

Preparing Your Daisies For Fall And Winter

Pruning is good because you will have attractive daisy flowers during winter and allow new growth in spring.

Cut Half The Stem

The African daisy will experience its last bloom in early fall and will be 3 or 4 feet tall. Cut the stem in half so that the plants remain between 1.5 and 2 feet tall. This allows the flower to focus most of its energy on sustaining the leaves instead of producing seeds. 

Cut The Dead Flowers

As fall progresses, cut off all the dead daisies you see. They will be brittle, so you can bend and break the stems close to the ground.

Afterward, cut the stems 3 to 4 inches above the ground. When the stems are not cut off, the stems of the dead daisies will not be green, and the flowers look slimy and unappealing. 

Cut Daisy Stems Above Soil Line During Winter

After the first frost, prune your daisies by trimming the stems so that they are 1 to 2 inches above the soil.
