What bug is eating my vinca?

Insect attacks on this plant are few but can happen on occasion. Some of the more commonly seen pests on annual vinca plants include aphids, spider mites, scale and whiteflies. Generally, most of these pests can be controlled with beneficial insects that feed on them or with the use of insecticidal soap or neem oil.

What is killing my vinca plants?

The problem is a fungus, often referred to as vinca sudden death, that lives in the ground. Water from rain or sprinklers splashes spores from the fungus up onto the plants, where it grows and quickly kills the entire plant, often in as little as 48 hours.

Why are my vincas turning brown?

Phytoptora root rot symptoms on vinca

How do I get rid of aphids on my vinca?

Make a homemade insecticidal soap, a low-toxicity bug control solution that will desiccate the soft bodies and kill the aphids without doing harm to your plants. Simply mix a few teaspoons of liquid dish soap with one quart of water, then spray or wipe the solution onto the leaves, stems, and buds of the plant.

How do you treat Vinca fungus?

Why are the leaves on my vinca curling?

Why are my vincas turning yellow and dying?

Vincas with yellowing leaves are often reacting to a lack of iron, which is a common problem in alkaline soil. A lack of nitrogen in the soil can also cause yellowing leaves. Use of a fertilizer containing nitrogen, iron and sulfur helps to replace the nutrients while balancing the pH.

Can Vinca take full sun?

Since annual vincas are native to Madagascar, they need the summer heat to thrive. Full sun is best, but they can take part shade if there's good air circulation. If an area is too stuffy, the plant can develop fungal problems. Vinca can also stand up to drought.
