Reasons for African Violet Leaf Spots
African violets are beloved houseplants for their bright flowers and shaggy leaves. Spots on African violet leaves are signs that something is wrong with the growing environment. Below are the possible causes with their respective solutions:
Water quality
Watering is a crucial element to master when growing African violets indoors. I recommend using distilled or rainwater to water your houseplant with tap water.
Tap water contains chlorine and fluoride minerals which brown spots on african violet leaves. Leaf spots prevent the African violet from flowering and developing healthily.
Let the tap water sit overnight and place the minerals in the bottom of the container. Drain the water slowly and water your houseplant.
Rust on African Violet Leaves it is also an indicator of poor water quality. If you like African violets, try using distilled or rainwater for irrigation.
natural aging process
Each leaf of the African violet will live for up to 12 months with an adequate supply of nutrients and other essential minerals. The fluffy leaves distinguish the African violet from other plants.
The plant stops sending essential nutrients and minerals to the leaves as it approaches its life cycle in order to conserve energy for better leaf functioning.
If you notice the leaves turning yellow and developing spots, feel free to prune them. It is an indicator of the natural aging process which is inevitable.
excess water problem
The African violet plant thrives in slightly moist potting soil. Soil conditions keep the houseplant happy and healthy.
Too much soil moisture due to too much water can lead to: Brown stains Yes hanging leaves. The damp environment will choke and kill the roots.
Use fertile, well-drained potting soil to solve the overwatering problem. The ideal potting soil will also help prevent African violet leaves from developing brown or white spots.
Make sure the pot to grow your African violet has drainage holes in the bottom to drain excess water. Follow a strict watering routine to avoid over or under watering.
Fogging aluminum foil with cold water
Foil misting is a crucial practice when growing houseplants. Helps increase humidity around the houseplant and promotes better growth.
Applying cold water to African violet leaves will cause brown and black spots when exposed to sunlight.
I recommend using lukewarm water to spray the leaves. Create a favorable growing condition for African violet plants. Make sure the area gets a free flow of fresh air to avoid pests.
extreme temperature
The potted African violet prefers a temperature range of 65-80OF (18-27.)OC). The condition keeps the houseplant happy and healthy.
Any temperature below 55°F (13°C) and above 85°F (30°C) is toxic to African violets. It causes crown rot, leaf spot, which causes the upper leaves to turn brown and mushy.
Use a digital thermometer to monitor indoor temperature changes. Try to regulate the temperature and create suitable growing conditions.
Over-fertilization
African violets are among the tropical houseplants that thrive on light. Fertilizers help nourish the plant and promote beautiful hairy leaves.
Too much fertilizer will eventually cause leaf rot. The condition will result in brown spots and soft leaves.
Too much boron and nitrogen or too little calcium and potassium in the soil can also lead to dry, brown, crusty leaf tips on the African violet plant.
I recommend flushing the potting soil every three months to prevent excessive salt buildup. Be careful not to fertilize your houseplant during the winter season.
parasitic infection
African violets are less susceptible to pests. But this does not mean that the houseplant is invisible to pests.
The pests extract vital nutrients from the leaves by piercing and injecting poison. The poison causes brown spots on the leaves after healing.
Use insecticidal spray to kill pests on your houseplant. Be sure to examine your African violet for pests with each watering.
plant diseases
African violets are less susceptible to common plant diseases. But any indoor plant lover should provide proper growing conditions to prevent these diseases.
Leaf nematodes are a deadly disease that causes shiny brown spots under African violet leaves. These microscopic worms are due to poor growing conditions.
