Cultivation
Saintpaulia goetzeana Engl. is a relatively easy-to-grow plant that thrives in a bright spot with indirect sunlight. Being a tropical plant, it requires a consistently warm temperature of 18-26ºC all year round. As such, it's ideal for indoor cultivation, but if you live in a warm climate, you can grow them outside protected from direct sunlight.
Watering Needs
The watering needs for Saintpaulia goetzeana Engl. are distinct. You should water your plant from the bottom, placing its pot in a saucer filled with water. The plant will then drink the water it needs through the drainage holes at the bottom of the pot. As for the frequency, it depends on the soil's dryness. The soil should be moist, but not wet, so watering once every five to seven days is enough.
Fertilization
Fertilizing your Saintpaulia goetzeana Engl. plant every three to four weeks is recommended to encourage steady growth and flowering. A diluted fertilizer should be used during the growing season of spring and summer. Do note that over-fertilizing can be detrimental to the plant's health, causing burnt roots and stunted growth.
Pruning
Pruning your Saintpaulia goetzeana Engl. plant is essential to maintain its growth and flowering. The optimal pruning time is when the blooms die, using scissors to trim off any withered or yellow leaves or flowers. Pruning also helps to maintain the plant's shape and reduce its size if it grows too large. It's wise to cut the leaves or stems at their base to avoid damaging the remaining portion of the plant.
Propagation of Saintpaulia goetzeana Engl.
Saintpaulia goetzeana Engl., commonly known as African violet or Usambara violet, is a popular houseplant that can be propagated by various methods. These include:
1. Leaf Cuttings
Leaf cuttings are the most common method used to propagate Saintpaulia goetzeana. To do this, select a mature and healthy leaf from the parent plant and remove it by making a clean cut at the base of the leaf stem. Place the leaf stem in a container filled with a well-draining soil mix and insert it about an inch deep. Water the soil and cover the container with a plastic bag to create a humid environment. After a few weeks, new plantlets will start to emerge from the base of the leaf stem.
2. Division
Dividing a mature Saintpaulia goetzeana plant is another easy way to propagate it. First, remove the plant from its pot and carefully separate the offsets from the parent plant. Each division should have a healthy root system and at least two to three leaves. Repot each division into a new pot filled with a well-draining soil mix and water it thoroughly.
3. Water Propagation
Water propagation involves placing the leaf stem of Saintpaulia goetzeana in a container filled with water. Make sure the bottom of the stem is submerged in the water and keep changing the water regularly to prevent contamination. After a few weeks, new roots will start to develop from the base of the leaf stem. Once the roots are about an inch long, transfer the stem to a container filled with a well-draining soil mix and water it thoroughly.
Propagation of Saintpaulia goetzeana can be a fun and rewarding experience. With a little patience and care, you can create more of these beautiful houseplants to decorate your home or give as gifts.
