- Divide clumps every three years: Periwinkle forms clumps over time , and it is advisable to divide them every three years to prevent overcrowding and maintain optimal growth.
How To Grow Periwinkle From Seed
Here are the steps to follow to ensure successful germination and growth:
- Start indoors: Sow periwinkle seeds indoors about eight weeks before the last expected frost date in your area. Use a high-quality potting mix and sow the seeds thinly, covering them with a light layer of soil.
- Provide adequate light and moisture: Once the seeds have sprouted, place them on damp paper towels in a sunny window. Make sure to keep the paper towels moist and provide plenty of light to encourage healthy growth.
- Transplant seedlings: When the seedlings have grown their first true leaves, transplant them into individual pots filled with potting mix. Keep the soil evenly moist, and provide adequate light to encourage optimal growth.
- Move outdoors: After all danger of frost has passed, move the seedlings outdoors to their permanent location. Choose a spot with partial shade and well-drained soil.
- Provide proper care: Water your periwinkle seedlings regularly, especially during dry spells. Fertilize them every two weeks with a balanced fertilizer to promote healthy growth and abundant blooms
How to Grow and Care for Periwinkles
Taking care of periwinkle plants is essential for their optimal growth and health. Here are some tips for periwinkle care:
- Provide good air circulation: Periwinkle requires good air circulation to prevent fungal diseases, so make sure not to overcrowd them.
- Maintain even moisture: Water periwinkle plants only as needed to maintain an even moisture level. Avoid overwatering as it can cause root rot.
- Deadhead spent flowers: Regularly remove spent flowers to encourage new growth and prolong blooming.
- Fertilize monthly: Apply a balanced fertilizer that contains nitrogen, phosphorus, and potassium once a month during the growing season to promote healthy growth and abundant blooms.
- Mulch: Mulch around periwinkle plants to help retain soil moisture and reduce weed growth.
- Provide proper light: Periwinkle requires at least 6 hours of bright light daily. This can come from natural sunlight or artificial lighting.
- Choose well-drained soil: Plant periwinkle in rich, well-drained soil that is slightly acidic (pH 5.5-6.8). Avoid planting them in areas with standing water as they prefer well-drained soil.
- Consider growing in a greenhouse: In areas with wet winters, consider growing periwinkle in a greenhouse or under lights to provide the ideal growing conditions.
Pruning
Pruning is an important part of maintaining healthy and attractive periwinkle plants. When periwinkles are young, they tend to grow quite vigorously, and pruning can help keep them in check. Pruning is also necessary to remove weak or damaged branches, which can be detrimental to the overall health of the plant.
In addition to removing weak or damaged branches, it’s important to cut off dead foliage at ground level. This not only helps maintain the appearance of the plant but also promotes new growth. Dead foliage can attract pests and diseases, so removing it promptly is crucial to the plant’s health.
When pruning periwinkle, it’s important to use sharp and clean tools to prevent damage or disease transmission. Pruning should be done during the plant’s dormant period, which is typically in late winter or early spring. Regular pruning will help promote healthy growth and ensure that your periwinkles remain vibrant and attractive throughout the growing season.
Propagating Periwinkles
Periwinkles can also be propagated through stem cuttings. Take cuttings from healthy, mature plants in the spring or early summer when the plant is actively growing. Cut a 4- to 6-inch stem below a leaf node and remove the leaves from the bottom half of the cutting. Dip the cut end in rooting hormone and plant it in a pot filled with moist potting mix. Cover the pot with a plastic bag to create a mini greenhouse and keep the cutting in bright, indirect light. Water the cutting regularly to keep the soil moist and mist it occasionally to maintain humidity. In a few weeks, the cutting should develop roots and can be transplanted to a larger pot or into the ground.
When propagating periwinkles, it’s important to choose healthy and disease-free plants. Use clean gardening tools and sterile potting mix to prevent the spread of diseases. It’s also recommended to propagate periwinkles during cooler months when the plant is less stressed and has a better chance of successfully establishing new roots. With proper care and attention, periwinkles can be easily propagated and provide a beautiful addition to your garden.
How to repot a periwinkle flower
Repotting a periwinkle flower is an important step in maintaining its health and growth. Here are some steps to follow for a successful repotting:
- Choose the right time: The best time to repot a periwinkle is during its active growth period, which is usually in the spring or early summer. Avoid repotting during the winter months when the plant is dormant.
- Choose the right pot: Select a pot that is one size larger than the current pot. It should also have drainage holes to allow excess water to drain out.
- Prepare the pot: Fill the bottom of the pot with a layer of potting mix, about one-third of the pot’s depth.
- Remove the plant: Gently remove the periwinkle from its current pot, being careful not to damage the roots.
- Loosen the roots: Gently loosen the roots with your fingers, removing any old soil or dead roots.
- Place the plant in the new pot: Place the periwinkle in the center of the pot and fill the remaining two-thirds of the pot with potting mix. Firmly press the soil into the sides of the pot to ensure the plant is stable.
- Water the plant: Water the plant thoroughly to help settle the soil and promote root growth.
- Place the plant in its new home: Place the newly repotted periwinkle in a spot with bright, indirect sunlight and maintain regular watering and care.
By following these steps, your periwinkle should thrive in its new pot and continue to bring beauty to your home or garden.
Pests and Diseases
Periwinkles are vulnerable to a range of pests and diseases that can affect their growth and health. To maintain the health of your periwinkle plants, it’s important to keep an eye out for signs of damage and take preventive measures as needed.
One common pest that attacks periwinkles is aphids. These small insects feed on the plant’s sap and can cause stunted growth and distorted leaves. Mites can also be a problem, particularly in dry weather. To control these pests, you can use insecticidal soap or horticultural oil, which are both effective and safe options.
Periwinkles can also be affected by a range of diseases, including powdery mildew, leaf spot, black rot, rust, and wilt. These diseases are typically caused by fungal pathogens and can cause discoloration, yellowing, and wilting of the leaves. To prevent the spread of these diseases, it’s important to remove any affected leaves and improve air circulation around the plant. Fungicides containing copper or sulfur can be used to control these diseases, but it’s important to follow the instructions carefully and use them only as needed.
In addition to pests and diseases, periwinkles can also be affected by environmental stressors such as drought, excessive heat, and cold temperatures. To minimize the risk of damage, it’s important to provide the plant with adequate water and nutrients, and to protect it from extreme weather conditions.
