Shasta daisies are perennial plants that benefit greatly from attentive deadheading and seasonal pruning. Pruning chores are done throughout the blooming season, beginning with propagation and ending with shearing. Hand shears and a spade are all you need to get started. This process takes around 20 minutes to 1 hour, depending on your daisy bed.
- Propagate your daisies when they start growing
Do this for healthy flowers and vigorous growth. Dig up your daisies every 2 to 3 years and remove the dead stems. Divide each plant into 2 or 3 pieces using a sharp spade. Replant each piece 2 feet apart in well-drained soil with full sun.
- Maintain your plants during the growing season
Deadhead flowers as soon as they begin to fade by cutting the stem at the next leaf grouping. Maintain the plant by removing any dead or diseased leaves or stems as they occur. Make sure to disinfect your hand shears and wipe them after each cut to prevent the spread of infection.
- Prune for seasonal renewal
If your winters are cold, cut your daisy plant back to its leafy base 2 to 3 inches from the ground when it begins to die. In warmer climates, simply prune dead leaves and stems.
