They perform best when they receive filtered light or dappled shade through a tree canopy. In indoor conditions, they can thrive under fluorescent lights or other LED grow lights that mimic natural light.
Temperature Conditions
These tropical plants require warm temperatures to grow, and they can die if exposed to frost or freezing temperatures. Ideally, they thrive in temperatures between 60°F to 85°F, with a humidity level of 60-80%. Low temperatures can lead to leaf yellowing and dropping, while high temperatures can cause wilting and leaf burn.
Soil Requirements
Impatiens zombensis Baker grows well in well-draining, rich soil that is kept moist but not waterlogged. The soil should be slightly acidic, with a pH level of 5.5 to 6.5. Potting mixtures with peat moss, perlite, and vermiculite are ideal for the plant to grow to its maximum potential. The soil should also be rich in organic matter and nutrients like nitrogen, potassium, and phosphorous to thrive and remain strong.
Cultivation methods
Impatiens zombensis Baker requires a well-draining soil with high organic matter for optimal growth. It is best to plant them in a partially shaded location, where they can receive light but not direct sunlight. Before planting, amend the soil by adding compost or well-rotted manure to provide the necessary organic matter. These plants prefer slightly acidic soil with a pH range of 6.0 to 6.5.
Watering needs
Impatiens zombensis Baker likes to grow in moist soil. Therefore, it is necessary to keep the soil consistently moist but not soaked to avoid root rot. Water the plants deeply at least once a week during dry spells, and avoid watering the foliage to prevent diseases. It is better to water early in the day, allowing the foliage to dry before the evening to reduce the risk of fungal growth.
Fertilization
Fertilizing Impatiens zombensis Baker throughout the growing season helps produce lush growth and more blooms. Use a balanced slow-release fertilizer or a half-strength liquid fertilizer every two to three weeks during the growing season. Avoid using high-nitrogen fertilizers and over-fertilization, leading to weak growth and limited flowering.
Pruning
Impatiens zombensis Baker does not require significant pruning to grow healthy, but removing dead flowers and yellowing leaves can promote new growth and increase aesthetic appeal. Pinching the tips of the plant occasionally can also encourage bushier growth and more flowers. However, avoid severe pruning, as it can limit flowering and weaken the plant.
Propagation of Impatiens zombensis Baker
Impatiens zombensis Baker, commonly known as the zombie balsam, is an herbaceous plant that belongs to the family Balsaminaceae. It is endemic to the Eastern Arc Mountains of Tanzania and is an excellent addition to a tropical garden. If you wish to propagate this plant, several methods can be employed.
Seed Propagation
The most common method of propagating Impatiens zombensis is through seeds. The ideal time to plant seeds is during the spring. The seeds should be soaked in water for 24 hours before planting them in a potting mix. The potting mix should be kept moist but not waterlogged, and the container should be placed in indirect sunlight. In about two to three weeks, the seeds will germinate, and the seedlings can be transplanted into individual pots or directly into the garden.
Cuttings Propagation
Another propagation method is through cuttings. Cuttings should be taken from healthy, mature plants during the growing season. The cutting should be about 6 inches long and should not have any flowers or buds. It is recommended to take cuttings in the morning when the plant is hydrated. Remove the lower leaves of the cutting and dip the cut end in a rooting hormone, then plant it in a well-draining potting mix. The container should be kept in indirect sunlight, and it should be misted occasionally. In about two to four weeks, the cutting will develop roots and can be transplanted into an individual pot or directly into the garden.
Division Propagation
Impatiens zombensis can also be propagated through division. The ideal time to divide the plant is during the early spring or fall. This method is only recommended for mature plants that are at least two years old. Carefully dig up the plant, and divide it into two or more clumps. Make sure each clump has roots, stems, and leaves. Transplant each clump into individual pots or directly into the garden. Water the transplants thoroughly, and place them in indirect sunlight until they establish roots.
Propagation of Impatiens zombensis is relatively easy and straightforward. Whether you choose to propagate through cuttings, seeds, or division, proper care and attention are essential to ensure the success of the new plant/s.
