Vincas also prefer somewhat acidic soils, so adding compost or mulch may be beneficial.

What kind of fertilizer should I use for my vinca plants?

A balanced fertilizer is best for vinca plants. Look for a fertilizer that contains nitrogen, phosphorus, and potassium such as 10-10-10 or 8-8-8. Avoid fertilizers with high amounts of nitrogen as this can cause the plants to become leggy and weak. Apply the fertilizer every 2-3 weeks during active growth for best results. Additionally, be sure to water your vinca plants regularly as they do not tolerate drought conditions well.

When should I prune my vinca plants?

Vincas can be pruned in late winter or early spring before new growth begins. Pruning will promote bushier, more compact growth and also remove any dead or diseased foliage that may have occurred over the winter months. Be sure to use sharp pruners and make clean cuts just above a leaf node on the stem of the plant. After pruning, apply a balanced fertilizer to help promote healthy new growth.

When should you plant vinca seeds?

Vinca seeds should be planted in late winter or early spring when the soil temperature reaches above 60°F (15°C). Before planting, mix some compost or other organic material into the soil to improve drainage and fertility. If you are sowing directly outdoors, rake the area smooth and remove any weeds or debris. Make sure that your chosen site has full sun exposure. Next, sprinkle a thin layer of vinca seeds over the prepared soil bed. Gently press them down with your hands to ensure good contact between seed and soil. Depending on how big you want them to grow, space the seeds 4-6 inches apart.

When should you plant vinca seeds?

Water well, making sure not to disturb the seeds too much in the process. Keep the soil consistently moist until germination, which usually takes around 10-14 days. When the seedlings are about 2 inches tall, thin them to their desired spacing. For larger plants, thin to 12 inches apart; for smaller ones, 6-9 inches apart should do it. Finally, mulch the area with an organic material such as wood chips or straw to help keep moisture in and weeds out. Now that you’ve planted your vinca seeds, they need proper care to ensure a healthy growth season! Make sure to water regularly and provide supplemental fertilization every few weeks during the growing season.

Can vinca be rooted in water?

Yes, it is possible to root cuttings of vinca in water. To do this, take a cutting from an existing plant about 6 inches long and remove the lower leaves. Place the cutting in a glass or jar filled with water and place it in bright but indirect sunlight. Change the water every few days to keep it fresh and within a few weeks you should start seeing roots growing from the cutting! Once they’ve reached several inches long, transfer them to moist soil to finish their growth cycle. With proper care, your new vinca plants will thrive!

How do you winterize vinca?

Vinca plants are very resilient and can survive cold temperatures. To winterize vinca, trim back the plant in fall to remove any dead or damaged growth. Make sure you leave enough foliage on the plant so it has some protection against frost. Covering the area with mulch is also recommended as this helps insulate the soil and slow down water loss during colder months. Additionally, watering your vinca sparingly throughout the winter will help them stay hydrated and reduce freezing risks.
