The African violet belongs to the genus Saintpaulia (Streptocarpus), which also comprises numerous other varieties of blooming perennials. Despite their common name, they are not related to violas; rather, the term was given to them because of the attractive flowers they produce. African violets can bloom in a range of colors, including blue, violet, lavender, pink, red-violet, lavender-pink, white, and purple, despite the fact that we often associate them with the color purple. African violets are indigenous to Tanzania’s high-elevation tropical rainforests.
The most distinctive feature of African violets, outside the blooms, is their fuzzy, succulent foliage. An adaptation to assist the plant collect water from the air is the fine hairs on the leaves. The decorative value of some cultivars is increased by the presence of ruffled or variegated leaves.
Depending on the variety, African violets can reach heights of 2 to 6 inches and widths ranging from 3 to well over a foot. The majority of the plants have flower clusters in the center, barely above the foliage, surrounded by layers of dark green leaves that resemble rosette shapes. Some varieties have blooms with bicolored petals, semi-double or double layers of petals, trailing growth patterns, or microscopic size. Plants that are properly cared for can bloom practically continually.
How old are African violets on average?
Because of their long lifespan, repotting these blooms is crucial. “Remember that African violets have a very long lifespan and have been said to endure up to 50 years,” says Ryan McEnaney, public relations and communications specialist at Bailey Nurseries. To avoid becoming overly root-bound, plants can be repotted into larger pots as they mature. Once your African violet has doubled or tripled the size of your container and the leaves are starting to wilt, it’s definitely time to make the move, says McEnaney.
However, you don’t have to repot your plants right away. If your African violet appears to have outgrown its container, don’t rush to relocate it, advises Brian Parker, senior merchant for Live Goods at Home Depot. “African violets are best when their roots are in a little bound condition,” he adds. “They will produce and perform for years and years with just a simple routine of the right light and food,” the speaker said.
Are African violets sun-sensitive?
The vibrant African violet blossoms are particularly lovely. They’ll provide color right away to any space.
Even during the gloomier winter months, they have a reputation for continuing to bloom. Place them around the house so you may enjoy their vibrant hues and plush textures all year long.
Once you establish a routine for caring for African violets, you’ll discover that they expand with ease. But unless all of their fundamental requirements are satisfied, they won’t develop. Give them the proper temperature, light, and nourishment, and you’ll start to bloom right away!
How to Choose and Take Care of African Violets:
1. Start out strong. Select a plant with the desired blossom color and vivid emerald foliage. Make sure the pot has openings for drainage.
2. The ideal lighting. African violets frequently don’t blossom because they don’t receive enough light. Because direct sunlight can burn the leaves, African violets require indirect light. For optimal results, pick a window that faces north or east. Keep plants away from cold glass, and turn the container once every week to ensure that all the leaves get enough light. African violets can be grown under a grow lamp to extend the day throughout the winter.
3. Remain cozy. The most comfortable temperatures for most people are between 70 and 80 degrees Fahrenheit during the day and 65 to 70 degrees Fahrenheit at night.
4. Subsurface water. Water should be at normal temperature to fill the saucer. Pour off any extra water after letting it settle for about an hour. Between waterings, let the plant dry out completely.
5. Use the new liquid Violet from Espoma to fertilize! Every two to four weeks in the spring, summer, and fall, indoor houseplant food.
6. Be thoughtful before replanting. Only when a plant is root-bound will an African violet bloom. Use organic potting soil designed exclusively for African violets, such as Espoma’s African Violet Mix, when it comes time to repot your plants. Choose a pot that is about a third the diameter of their leaf spread in diameter because they flower best in compact pots.
Light
When African violets receive the proper quantity of light, they develop normally, maintain good health, and produce a lot of flowers.
Results are good when 1,000 foot-candles of light are used for 6 to 8 hours each day. A sunny, east or west window or a bank of four fluorescent shop lights provide more light than this. Low light levels are also tolerable for violets (200 to 500 foot-candles).
The best light in winter comes from windows facing south or west. Windows with east or north exposures perform best during the warmer months.
Probably the most frequent cause of an African violet’s failure to flower is a lack of light. When violets are growing in insufficient light, the leaves get a darker green and become thin. Additionally, the petioles, or leaf stems, become exceedingly long and flimsy.
Too much sunlight will cause the leaves of violets to turn a pale yellow-green color. Dead, charred, or bleached-out places could also exist. To ascertain whether the light intensity or duration in your home is enough, some research and testing may be required. You might need to use a very sheer curtain where plants must be grown in windows with strong light to diffuse and lessen the light reaching the plants. Because of their short stems and slower growth, plants in an extremely high light intensity risk being burnt or, at most, become quite compact.
Artificial light makes it simple to grow African violets. It is advised to use an intensity of about 600 foot-candles for 14 to 16 hours each day. Lights may be turned on and off automatically with inexpensive timers.
The most popular type of lighting, fluorescent bulbs can be stacked or fastened to shelves to provide an appealing and practical light source. 12 to 15 inches above the tops of the plants is the ideal height for the tubes. Many plants can be grown on a shelf with two or more 20- to 40-watt tubes. Numerous businesses provide fluorescent tubes intended exclusively for plant development. There is more useful radiant energy in the light that is released. However, most indoor gardeners find success with more affordable “Cool White” tubes. The fluorescent tubes may be paired with one or two incandescent bulbs.
Due to their low light spectrum and heat output, regular incandescent bulbs are not advised as a sole source of illumination. There are 75 and 150 watt incandescent spotlights made specifically for plants. They are most effective when placed between 12 and 18 inches away from the plants.
Temperature
The most beautiful violets are cultivated at a temperature of 70 to 90F during the day and 65 to 70F at night. Low temperature plant growth will result in malformed plants. The leaves could cup, curl down, and get brittle. Flowers could be discolored and distorted. At colder temperatures, foliage may also be a light green, especially when grown in the right lighting circumstances. Plants growing near windows or in drafts may have damaged leaves.
Avoid placing the plants where it is more than 90 degrees or less than 60 degrees for optimal results.
Humidity
A healthy violet’s growth depends on humidity, or the amount of water vapor hanging in the air. Despite the humidity levels found in typical homes, violets can thrive and bloom there. Plants thrive best in environments with a greater humidity level. There are gadgets that raise indoor humidity for the benefit of both people and plants.
Setting the pots in watertight metal or plastic trays filled with water and gravel or pebbles can boost humidity when a few plants are involved. Water in the tray should always be at a shallow level. The pots shouldn’t be placed in water; instead, place them on rocks or upside-down shallow pot saucers.
Planting violets in big glass goblets, aquariums, or terrariums is a current trend to make humidity control easier.
Soil Moisture
Your success in growing African violets depends on the moisture content of the soil and appropriate watering. Too much or too little water can kill plants. The soil, the size of the pot and the plant, and the environment all affect how much and how frequently to water. You must therefore determine your plants’ specific moisture needs and create a customized watering schedule.
There are instruments and moisture meters available to measure soil moisture. A simpler (and less expensive) technique is to just touch the soil’s surface with your finger tips, however some of these are reasonably dependable. Between waterings, let the soil become a little bit dry, but don’t let it get too dry because wilting can harm the roots.
Apply water until the bottom of the pot is drained. At the end of 20 to 30 minutes, pour out the surplus.
Ring spot is caused by light green, discolored spots that develop when leaves are slapped with cold water (55F or lower). Even a 10F temperature difference between the leaves and the water might cause damage. However, if the water is warmed to room temperature, damage can be avoided.
Many producers of violets choose watering from the bottom of the pot as opposed to the top. Although this works well, salts that might build up in the soil are not leached. Every now and then, water all plants from the top with warm water to flush out salts and eliminate dust.
Without drainage holes, plants in containers are significantly more vulnerable to overwatering issues like root rot or stem rot.
In comparison to plants in low light and high humidity, those in high light and low humidity require more frequent watering. A heavy, poorly drained soil mixture has to be watered less frequently than a coarse, well-drained soil mixture.
As plants outgrow their pots, it becomes increasingly difficult to maintain the proper soil moisture. Repotting crowded plants into the next larger size pot is advised.
Soils
There is a huge variety of soils and soil combinations in which African violets can grow. The best results for gardeners come from soil that is well-drained, well-aerated, and includes a lot of humus or organic matter. A mixture of one part leaf mold, one part peat moss, one part sand, and two parts loamy top soil typically produces good results.
Violets grow well in artificial mixtures like peat-vermiculite and peat-perlite. They are largely pest- and disease-free and relatively clean. Soil, peat moss, and horticultural perlite can all be used in equal amounts to create a mixture. Perlite can be replaced by vermiculite.
Because the quality of artificial mixtures is more reliable than that of sand or soil, some producers of violets prefer them. The finest soil for growing violets is sterilized potting soil or a specialized African violet soil mix.
Potting
Keep take mind that violet leaves, stems, and root systems are extremely delicate and easily broken when potting them.
More than one crown is typically present in older plants. After carefully removing the plant from the pot, cut into the root ball with a sharp knife to separate the crowns. Take care not to remove all the soil from the root systems or to completely damage the roots.
Repotting requires filling the pot only partially with soil. Set the plant so that its crown is roughly 1/4 to 1/2 inch below the pot’s rim and slightly higher than the soil level. Surrounding the old root ball, gently compact the dirt.
Keep in mind that plants thrive in containers with drainage holes. To stop soil from washing through the perforations, use a covering of pebbles, bits of pantyhose, or shattered pots.
Fertilization
Like most plants, violets benefit from regular fertilizer applications. Every four to six weeks, most violet hobbyists like to use liquid or water-soluble fertilizers like 20-20-20. It is also possible to utilize dry fertilizers and slow-release or encapsulated fertilizers. Make sure the soil is moist before applying a dry fertilizer.
No matter what type of fertilizer you use, read and abide by the manufacturer’s instructions.
Less fertilizer may be needed for plants that are growing in non-active stages or in less than optimum environments. African violets are extremely susceptible to soluble salt buildup, which can harm plant roots. However, too little fertilizer may result in a slowdown in growth and/or other deficiency signs. Many indoor gardeners find that they achieve their best results with one-third to one-half the suggested amount of fertilizer. Also be in mind that excessive fertilizer can occasionally cause symptoms that resemble shortages. Your best resource for identifying the issue will be a soil test.
Propagation
By division, African violets can be easily multiplied (see Potting). Leaf-petiole cuttings can also produce more violets, although it takes longer for the plant to bloom. A few types of African violets can be produced from seeds, though. Under ideal conditions, a leaf cutting or seed can grow into a flowering plant in around 10 months.
Making a greenhouse out of two 8 x 12 inch clear plastic storage boxes is the easiest way to propagate violets. 4 inches of potting soil should be placed in the bottom of one box. Violet leaves should be inserted into the soil after it has been moistened, about a half inch deep. Tape the sides together and place the other storage box’s transparent plastic bottom on top. Put the box in a window facing the east or south. In 8 to 10 weeks, young violet plants will emerge, and in three months they will be prepared for transplanting.
It is advisable to avoid adding fertilizer when potting freshly rooted cuttings. However, you might want to apply 1/4 to 1/3 teaspoon of a complete African violet fertilizer for each 5-inch pot volume of soil combination when dividing or moving huge plants to larger pots. To avoid damaging the roots, thoroughly incorporate the fertilizer into the soil. The best results come from a slightly acidic soil mixture (pH 6.0 to 6.5).
