As an avid gardener and African violet enthusiast, I’m often asked about the best practices for growing healthy, vibrant African violet plants Of all the care tips I share, proper spacing is one of the most crucial factors in cultivating a stunning African violet garden In this article, I’ll explain why spacing is so important for these delightful houseplants and provide key strategies to space your African violets perfectly.
Why Proper Spacing Matters
African violets are compact, low-growing plants that thrive when given adequate access to light, moisture and airflow. When planted too close together, they compete for resources, often resulting in weak, leggy growth, fewer blooms and increased susceptibility to diseases.
Alternatively, spacing plants too far apart can also cause issues. With insufficient warmth and humidity from neighboring plants, African violets may struggle to grow properly or produce flowers.
By optimizing the distance between each African violet according to its size and growth habits, you ensure every plant has sufficient space to develop strong, stocky growth and display gorgeous blooms.
Recommended Spacing Guidelines
The ideal spacing for your African violets depends largely on the size of the plant Here are some general recommendations
- Small varieties (up to 6 inches wide): Allow at least 6 inches between plants
- Medium varieties (6-12 inches wide): Space 8-12 inches apart
- Large varieties (over 12 inches wide): Give 12-18 inches between plants
Make adjustments based on your plants’ growth rates and habits. Fast-growing or trailing varieties may need more breathing room than compact, slow-growing types.
I also suggest allowing a few extra inches between plants prone to fungal diseases like powdery mildew. Improved air circulation helps prevent the spread of these contagious pathogens.
Tips for Proper African Violet Spacing
Follow these handy tips to ensure your African violets have adequate spacing:
-
Check spacing regularly. As plants grow, gaps between them shrink. Reevaluate proper spacing every 2-3 months.
-
Group same-sized plants together for even spacing and growth.
-
When repotting, choose containers allowing 1-2 inches between plants.
-
For mixed planters, space plants equidistant from each other and the container walls.
-
Remove lower leaves and stems to open up interior space and increase air movement.
-
Rotate pots frequently to ensure even light exposure.
-
Space plants further apart during winter when light levels are reduced.
-
Increase airflow with gentle fans to prevent fungal issues in densely planted areas.
Spacing African Violets Outdoors
For outdoor planting beds and containers, maintain spacing guidelines outlined previously. Additionally:
-
Plant in part sun to prevent overcrowding in optimal light areas.
-
Improve air circulation by spacing plants apart and avoiding protective walls or enclosures.
-
Space plants further apart than you would indoors to prevent disease transmission outdoors.
-
Ensure potted plants have room for air circulation between pots. Groupings look lovely but monitor for humidity issues.
Signs of Overcrowding
Watch for these red flags indicating overcrowded African violets:
-
Leggy, weak growth and sparse leaves along stems
-
Pale leaves and stunted plants
-
Fewer flowers or no blooms
-
Fungal diseases like botrytis or powdery mildew
-
Declining health and possible plant death
Address crowding immediately by transplanting individual plants to new containers or reconfiguring plantings to align with spacing best practices. This ensures your African violets thrive and rewards you with abundant blossoms.
Relish the Rewards of Properly Spaced Plants
A perfectly spaced African violet garden guarantees every plant has sufficient access to air, light, moisture and growing room. Adhering to optimal spacing guidelines takes a little diligence but pays off tremendously. Your African violets will thank you with full, healthy growth, vivid flowers, and enviable vibrancy. So be sure to implement these spacing tips to create a beautiful, flourishing African violet oasis!
How To Care For African Violets
If you are new to African violets here are some basic tips for African violet care to get you going. And if you just havent been successful with them in the past, these tips will get you back in the African violets good graces.
First of all, when buying a new African violet plant look for one with firm, healthy leaves and lots of healthy-looking buds.
I am not an African violet snob and will buy them at the local grocery store, but only if they are FRESH to the store and are looking extra PERKY. Otherwise, I prefer to buy them at my local garden center where I know they have been well cared for by someone with knowledge of plants (rather than knowledge of pastrami).
Starting with a healthy African violet plant is much, much easier than trying to revive one on its last legs.
I always repot my African violets as soon as I bring them home from the garden center or grocery store. The plastic nursery pots they are sold in at the stores are not optimum for long-term use, so into new pots they go.
And then I repot them once a year to give them fresh airy soil. The previous soil would have become compacted over time.
In both these instances I am repotting them in the same size containers. African violets bloom better when slightly rootbound, so until they become too rootbound or start to get leggy I try to keep them in approximately the same size planter.
In general, the pot should be roughly ⅓ the size of the spread of the leaves.
Wait to move them up in planter size when they become too rootbound – you will see roots growing out of the hole in the bottom of the pot or poking up out of the soil on top when they are at this point.

When repotting, use an African violet-specific soil such as Espomas African Violet Potting Mix . They like airy, loose and fluffy soil and regular potting mix is too heavy for them.
A note about Miracle Grow African Violet Potting Soil which is commonly found in just about any grocery store or hardware store. It already has fertilizer added in to it, so if you use it you have to remember to be careful to not over-fertilize your plants by using your own fertilizer also. Some people like that they dont have to think about fertilizing, some people like to control their fertilizer usage more.
And you can always make your own. A common recipe for making your own African violet potting soil is to mix 1 cup peat moss + 1 cup vermiculite + 1 cup perlite. So if you want to DIY it, go for it!
Fertilize your African violets with an African violet-specific fertilizer spring through fall. There is no need to fertilize in the winter months. I use Schultz African Violet Fertilizer, just because that is what my mom always used, but there are other brands out there. Follow the directions on the package.
Do you remember what I told you about the Miracle Grow potting soil though?
Let your African violets dry out slightly between waterings. I can usually just lift the pot and tell it needs water by the weight of the pot. Which might sound odd, but really the soil is so light that you can easily tell when it has the added weight of water in the soil. You should expect to be watering them approximately every 5-7 days depending on the humidity level in your home.
Water from underneath using room-temperature water. I fill the saucer or a shallow pan with water and allow them to drink up as much as they can from underneath for about an hour. Then toss out the extra water. They prefer moist, yet not soggy soil.
DO NOT let them constantly sit in water. They will become mushy and waterlogged and will die a fast miserable death from root rot.
African violets prefer bright, indirect light such as an East or North facing window. Direct sunlight will burn the leaves. And they are notorious for not re-blooming without the correct lighting situation.
Rotate once a week to keep their uniform, rounded shape.
You can place them under a grow light in the winter months if you like. I have not found it necessary, but some people swear by them.
They do best in 65 – 80 degree temperatures.
They need to be kept away from cold glass, so if you have them in a kitchen windowsill, pull them back a bit from the glass.
Before they became beloved houseplants, African Violets grew in the mountains in Tanzania where they were accustomed to a humid climate. In 1892 they were discovered by European colonists and brought back to England and eventually sent to the United States.
They prefer a humid environment which can be achieved by placing the pots on pebble filled tray of water. Be careful to not let the roots of the plants touch the water though, you are just allowing the water to slowly evaporate causing humidity for the plants. You can also use a humidifier in the room or even a bowl full of water near your plants.

I didnt want to make this article so long no one would read it, so pop on over to her site to learn how to propagate the right way (it is not hard at all)!
No, they are non-toxic to cats and dogs. BUT, if your animal or child is prone to sticking plants and flowers into their mouth, I would keep these pretty flowers out of their reach. And I would still contact the local poison control center to just make sure the amount of plant they ate wont have another effect on them. Just because they arent poisonous doesnt mean they wont upset their stomach.
There are 3 main reasons your African violet may not be blooming: Not Enough Light – African Violets need bright, indirect light to bloom. Place your plants near a North or east-facing window, but avoid harsh direct sunlight as it can burn the leaves. A shear curtain in the window is ideal to ward off the harshest light while still giving them the bright light they need. Too Large Of A Pot – African Violets bloom best when they are slightly root-bound. If youve recently repotted your violet into a huge new pot, the pot size might be the culprit. Incorrect Watering – African Violets are a bit finicky regarding water. Both over-watering and under-watering can cause blooming issues. Water them from the bottom when the top inch of soil feels dry to the touch. Do not wait until they dry out completely before watering.
Although African Violets like humidity around them, DO NOT MIST your plants directly. Water on the foliage will cause brown spots and will leave your plant open to disease, pests and leaf rot. If you are concerned about humidity levels for your plants you can set your pots on a pebble filled tray of water. Be careful to not let the roots of the plants touch the water though, you are just allowing the water to slowly evaporate causing humidity for the plants.
I prefer to use terra-cotta pots for my African violets since terra cotta is breathable. And honestly, I love the look of an African violet in these simple pots. You can use an African violet specific pot which self waters the plant if you prefer. In this case the planter comes in two parts. The plant is planted in the top portion with water put in the bottom portion. It really is a personal preference though, both type of pots will work. When picking out a pot, make sure it is slightly shallow though – roughly the same size in depth as in width. You do not want overly deep planters because the roots are shallow growing and in a tall planter you will end up with a plant with soggy soil at the bottom yet roots that havent touched water.
