It was the case that you might solely discover African violets with purple flowers.
As of late, breeders have coaxed every kind of thrilling hues out of the crops, with cultivars that bloom in pink, white, and even yellow.
I like to see the number of colours on the market, however the place I don’t wish to see odd coloration is on the foliage.
Let me make clear: there are variegated African violet varieties that sport enchanting whorls and swirls of cream and banana yellow that distinction with the inexperienced.
However leaves turning yellow after they aren’t purported to? That’s an indication one thing is mistaken.
We hyperlink to distributors that can assist you discover related merchandise. In the event you purchase from one in all our hyperlinks, we could earn a fee.
African violets might need yellow foliage for a variety of causes, starting from water points to lack of vitamins and even the dreaded root rot.
In our information to rising African violets, we cowl how one can domesticate these engaging crops in your house.
And should you’ve observed yellow leaves in your crops, this information will assist you determine what’s inflicting it and how one can resolve the difficulty.
Listed below are the widespread culprits we’ll focus on:
1. Not Sufficient Daylight
Discovering the right quantity of sunshine for African violets will be difficult. An excessive amount of and the leaves flip yellow, too little, and the identical can occur.
Within the case of too little gentle, you received’t see dry patches or discolored areas; they’ll be pale and wan throughout. New development will likely be leggy.
In case your African violet by no means blooms, has pale leaves, and nothing else appears to be mistaken, I’d put “too little gentle” on the high of your suspect record.
African violets can deal with fairly much more gentle than you may anticipate. In reality, they bloom finest with some all-day dappled solar or direct daylight within the morning. Ideally they need loads of vivid, oblique gentle.
Go forward and transfer it right into a barely brighter location, however do it progressively.
In the event you transfer the plant too rapidly, you’ll find yourself with the issue of sunburn. And that’s an entire different reason behind yellowing foliage.
If needed, you may also use supplemental develop lights. Place the lights 10 to 30 inches away from the African violets and go away them on for six to 12 hours a day, relying on how a lot pure gentle the houseplant is receiving.
2. Too A lot Daylight
When African violets are uncovered to an excessive amount of direct solar, it will possibly trigger burning on the leaves that turns them yellow.
As mentioned above, these houseplants want vivid, oblique gentle, and are ideally positioned close to a south-, west-, or east-facing window. However typically, that isn’t fairly sufficient gentle to encourage flowering.
So maybe you progress the plant right into a spot the place it’s going to obtain some direct morning solar.
Earlier than it, a lot of the leaves have turned yellow or tan and seem dry the place probably the most intense solar hits them.
And once I say “you,” I imply me. I’ve completed this just a few occasions in my impatience to try to assist my African violets produce flowers.
So long as the solar isn’t too intense, should you transfer your African violet to a brighter location, it’s going to ship out new foliage that is ready to deal with the brighter publicity.
I’ve discovered that direct morning solar for just a few hours is ok. However any quantity of afternoon solar in my space is means too vivid.
In case your African violet has sunburn, one of the simplest ways to resolve it’s to maneuver the plant again to a darker spot after which progressively transfer it someplace brighter – if you might want to.
We’re speaking about shifting it into direct solar for possibly half-hour on the primary day. You’ll be able to add one other half-hour or so each day for every week after which your plant needs to be prepared for all times within the limelight.
Prune off any solar broken leaves as they received’t heal and so they simply drain vitality from the plant.
3. Nutrient Deficiency
African violets are hungry! They’re the Labrador retrievers of the plant world, fortunately consuming out of your plate in addition to the leftovers on the countertop.
Nicely, that’s presumably an exaggeration about African violets, however not Labradors.
In the event you aren’t feeding your African violets virtually each time you water, it’s potential that your plant is ravenous.
Labs will let you know they’re feeling faint with starvation by looking at you longingly anytime you stroll within the common path of the kitchen. Your African violet will let you know by its leaves turning yellow.
Usually, it’s the older, decrease leaves that can change shade. If the entire foliage is discolored, I’d look to different causes earlier than nutrient deficiency.
Nitrogen and phosphorus deficiencies are the most typical, however an absence of any of the important vitamins may end up in yellowing leaves. To repair it, seize a light, all-purpose meals, dilute it to a couple of quarter energy, and feed the soil.
Each time you water after that, achieve this with fertilizer diluted to one-eighth energy.

4. Pest Infestation
The opposite day I used to be marveling at what number of critters in my backyard had been making an attempt to make a meal of the assorted bugs.
I watched as a downy woodpecker hunted via my mock oranges and an orb weaver devoured a wasp.
On the bottom, my chickens scoured the soil, and a ladybug hunted aphids on my roses.
Just a few hours later, the bats left their field on my chimney and began scooping up the mosquitoes hovering close by.
Outside, there are a number of creatures that maintain insect pests in examine. Indoors, it’s a distinct story. There aren’t any birds or bats, and I recurrently sweep out any spiderwebs.
So, when pests discover their means into your house and onto your plant, it will possibly rapidly develop into an enormous drawback. With out predators, they will reproduce and unfold quickly.
One of the crucial widespread indicators of pest feeding is yellowing leaves. It may be stippling or it may be an all-over shade change.
Not all houseplant pests will trigger discoloration, although. It’s usually people who feed by sucking the sap out of the plant, like aphids, mealybugs, and spider mites.
Look at any specimens you think of being infested for something which may appear like a pest, together with little oval bugs, webbing, or honeydew, which is the sticky feces they go away behind.
In the event you see any of these signs, it’s time to isolate the plant and spray it with a stream of lukewarm water over a sink or tub to knock off the pests. Then, deal with it with an insecticidal cleaning soap as soon as every week till you see no extra indicators of pest exercise.
The discolored leaves could not get better, so you possibly can prune these out if a big space of the leaf is affected. If it’s simply an edge or a spot right here or there, go away them in place to keep away from stressing the plant.
5. Root Rot
African violets like moisture, however not an excessive amount of. I like a superb hour within the sizzling tub, but when I needed to soak in it for twenty-four hours a day for weeks, I’d most likely begin turning yellow, too!
Whenever you constantly overwater a plant, you’re basically drowning the roots, stopping them from absorbing oxygen from the soil. That’s when the foliage modifications shade and may even begin to shrivel up and fall off.
Usually, there may even be soggy brown spots on the leaves, some wilting, and the foliage will begin to rot. The plant may even scent dangerous.
In the event you dig down into the soil or unpot the plant to have a look at the roots, you’ll discover that they’re soggy and pungent.
To repair root rot, prune off any useless foliage after which take away the plant from the pot. Wash away all of the filth and look at the roots.
Minimize off any which are soggy, damaged, black, or in any other case sickly-looking. Wash the container completely in sizzling soapy water earlier than repotting in contemporary soil.
