Poinsettias are a quintessential holiday plant with their bright red and green foliage bringing cheer during the winter months. While they are often treated as annuals and discarded after Christmas, with proper care and pruning poinsettias can be kept to bloom year after year, even in Florida’s warm climate.
Pruning is key to maintaining healthy poinsettia plants that will give you the best floral display when the holidays roll around again. Follow these tips to learn when, how, and why to prune poinsettias in Florida.
When to Prune Poinsettias in Florida
Pruning poinsettias at the right time is crucial for their growth and reblooming In Florida, the best time to prune poinsettias is in early spring, around March or April. This gives the plant time to recover and produce lush new growth during the summer before setting buds in the fall.
Specifically you’ll want to prune poinsettias soon after the colorful bracts fade and fall off which usually occurs in February or March in Florida. Pruning too early while cold temperatures still threaten can damage new growth.
Wait until all danger of frost has passed before pruning poinsettias. The ideal pruning time is just after the last expected frost date but before the plant starts putting out vigorous new growth.
How to Prune a Poinsettia
Follow these simple steps for pruning poinsettias correctly:
- Put on gloves to protect your hands from the milky sap that can cause skin irritation.
- Use clean, sharp bypass pruning shears to make smooth cuts and prevent disease. Dip shears in rubbing alcohol first to sterilize.
- Cut stems back to around 12-18 inches above the soil line. Remove all dead, damaged, or diseased growth.
- Give the plant a rounded, uniform shape by pruning evenly.
- Wipe sap off leaves and stems with a damp cloth to avoid damage.
- Remove spent blooms or faded bracts to keep the plant looking tidy.
Pruning stimulates branching and bushy new growth. It eliminates crowded, woody stems and makes room for vigorous new foliage. Never remove more than 30% of the plant when pruning poinsettias.
Ongoing Poinsettia Care
Year-round care is vital for getting poinsettias to rebound and rebloom after pruning. Follow these tips:
- Water whenever the soil feels dry 2-3 inches down. Allow it to dry between waterings.
- Fertilize monthly during active growth with a balanced fertilizer.
- Keep in bright, indirect light indoors or filtered outdoor sunlight.
- Maintain overnight temperatures above 60°F for lush growth.
- Repot in a larger container if roots become crowded.
- Pinch and prune as needed to encourage bushy growth.
- Disbud flowers in fall for a fuller floral display.
- Protect from frost and cold weather.
Proper sunlight, water, temperature, and fertilization will ensure your poinsettia thrives. Stop pruning by early November so flower buds can develop.

Follow these tips for successfully pruning poinsettias in Florida:

Maintaining a Good Environment for Reblooming
- 1 Water the plant regularly and ensure proper drainage. Poinsettias, like all plants, need water to grow, but they can be very sensitive to overwatering. Water the plant when the surface of the soil feels dry to the touch.[7]
- If you bought your plant in winter, it is likely to be in a pot wrapped in foil. Take the pot out of the foil in order to allow for drainage.
- 2 Keep the plant in a sunny place with a temperature of at least 55 °F (13 °C). The plant should receive a good amount of light, but should not be placed directly in the sun. Avoid drafty locations where temperatures may fluctuate during the day and night.[8]
- 3 Place the plants in complete darkness for 13 hours a day beginning in mid-September. For those characteristic bright red leaves, poinsettias need approximately 13 hours of absolute darkness per day for 8-10 weeks. Place them in a closet, under a box, or inside a cover, making sure that absolutely no light can get through.[9]
- Setting a daily alarm is the best way to remind yourself when to do this and keep you on track for beautiful plants during the holiday season.
- During the other hours of the day, the plant should receive normal lighting conditions.
