With this technique, roots should pull water up from the saucer, keeping the leaves dry. NOTE: Avoid tap or chlorinated water which is loaded with chemicals. Use distilled or rainwater for watering your African Violets. If your African Violet is in an office or an area of low-light, try moving it to a southeastern or western-facing window. Remove any yellow leaves. Spray your African violet with a solution of neem oil once a week until the pests are gone.
Make sure the spray covers the underside of the leaves and the stems. Keep the plant away from your other plants while treating pests until all the bugs are killed. You may want to drench the soil times per year to remove excess salt buildup, as well. They prefer sphagnum peat moss, which you can find at most garden stores. As for the yellow leaves that are already growing, you can pinch them off.
Warm the water and eliminate the salt if your African violet has limp leaves that eventually yellow and drop off. Use room temperature water to avoid cold damage to the leaves. Then check for a white crusty substance on the soil surface or plant container. This salt buildup is from the minerals in the water and fertilizer. African violet leaves are damaged and often drop when they come in contact with this material. In addition to bright sunlight, this plant also needs 8 hours of darkness to produce the bright red blooms.
The African Violet plants are relatively easy to grow but, they face few issues like any other plant. Most growers struggle with yellow leaves because African Violets leaves can turn pale or yellow due to several reasons.
The yellowing of the African Violet leaves does not necessarily have to be due to a problem. The leaves may lose color and yellow due to old age, which is a natural and inevitable process and not something to worry about. Providing the plant with excellent care may delay the process, but the lower leaves will eventually become yellow and drop. This is also a way for the African Violet plant to give rise to new foliage and direct more of its nutrients to new growth.
One of the leading causes of yellowing of African Violet leaves is incorrect watering. Yellow Leaves are a simple reaction to overwatering. If the soil remains wet for too long, the leaves will turn bleached and form ring spots on them. Another concerning reason is the water temperature. Low light is also disliked by these plants. Because if you place an African Violet in a dark room with insufficient lighting, the leaves react by turning yellow. Establishing a balance between extreme lighting conditions is essential to nurture a healthy African Violet plant.
Continuous exposure to high humidity without any care can lead to increased susceptibility to infections. By underwatering an African Violet, the leaves will become dehydrated, turn yellow and may begin to droop or shrivel up if it goes on long enough without water.
Instead you should be watering the soil fully, not the leaves, and water again while the soil is barely moist for best results. Aphids, scale bugs and mealy bugs are some of the pests you may encounter on an African violet that actually feed on the plants foliage and drain nutrients.
This can turn the leaves yellow as it will dry out the leaves which can also cause them to drop among other issues when pests are involved.
