In general, the soil should be moderately moist, but it should never become waterlogged as this can lead to root rot. It is advisable to improve the soil conditions by adding organic matter such as compost, which ensures good drainage and helps maintain the soil's moisture levels. This plant does not do well in heavy clay soils and sandy soils without enough organic matter.
Cultivation Methods
Pavonia burchellii (DC.) R.A.Dyer var. tomentosa (Ulbr.) Heine is a tropical shrub that prefers warm temperatures and abundant sunlight. It is best grown in well-draining soil that is rich in organic matter. This plant can be grown in containers or directly in the ground, and it is recommended to plant it in a location that has protection from strong winds.
Watering Needs
The Pavonia burchellii (DC.) R.A.Dyer var. tomentosa (Ulbr.) Heine plant requires regular watering. Ensure that the soil is moist, but not waterlogged. Water the plant deeply once or twice a week during periods of dry weather. Reduce watering in winter when the plant goes dormant.
Fertilization

Propagation of Pavonia burchellii var. tomentosa
Pavonia burchellii var. tomentosa is commonly propagated using seeds or cuttings.
Propagation by seeds
The seeds of Pavonia burchellii var. tomentosa are relatively easy to germinate. The seeds should be collected when ripe from the pods and should be cleaned and dried before sowing. The seeds can be sown in trays or seed pots containing a mix of sand and peat moss in equal parts. The trays or pots should be kept moist, but not waterlogged, and placed in a warm, brightly-lit area.
The seeds will typically germinate within 1 to 2 weeks. Once the seedlings have developed two sets of leaves, they can be transplanted into individual pots or containers containing a well-draining potting mix. The seedlings should be watered regularly and placed in a partially shaded area to avoid excessive sun exposure.
Propagation by cuttings
Pavonia burchellii var. tomentosa can also be propagated by cuttings taken in the spring or summer. Select healthy shoots from the parent plant and cut them into 3 to 4-inch sections, keeping at least 2 nodes on each cutting. Remove the lower leaves from the cuttings, leaving only 2 to 3 leaves at the top.
Dip the cut end of each cutting into rooting hormone and insert it into a pot filled with a well-draining potting mix. Water the cuttings thoroughly and cover the pot with a clear plastic bag to maintain high humidity. Place the pot in a bright, but slightly shaded area and keep the soil moist until the cuttings have rooted.
Once rooted, the new plants can be transplanted into individual pots or containers and grown on until they reach a suitable size for planting in the garden.
