Propagation of Sphaeranthus stuhlmannii O.Hoffm.
Sphaeranthus stuhlmannii O.Hoffm., commonly referred to as "African daisy," is a popular ornamental plant that is native to Africa. The plant belongs to the Asteraceae family and has bright yellow flowers that are borne in clusters. Propagation of Sphaeranthus stuhlmannii O.Hoffm. can be done by various methods, including:
Seed Propagation
The most common method of propagating Sphaeranthus stuhlmannii O.Hoffm. is through seed propagation. The seeds should be collected from mature plants in the early morning when they are dry and mature. The collected seeds should then be cleaned and sown in a pot that is filled with well-draining soil. The pot should be kept in a sunny location and watered regularly. Germination will occur within 2-3 weeks, and the seedlings can be transplanted to their permanent location after they develop their second set of leaves.
Cutting Propagation
Sphaeranthus stuhlmannii O.Hoffm. can also be propagated through cutting propagation. For this method, cuttings should be taken from healthy and mature plants. The cuttings should be 4-6 inches long and taken from the healthy branches. Remove the lower leaves, leaving a few leaves at the top. The cuttings should be planted in moist soil and kept in a warm location with indirect sunlight. Water regularly and in about 6-8 weeks, the cuttings should develop roots. They can then be transplanted to their permanent location.
Division Propagation
Division propagation is another method of propagating Sphaeranthus stuhlmannii O.Hoffm. that is used when the plant becomes too large. The plant should be dug out of the ground, and the root ball should be divided into smaller sections. Replant the divisions in well-draining soil and water regularly. The newly divided plants should be kept in a shaded location for a few weeks, after which they can be moved to their permanent location.
Overall, Sphaeranthus stuhlmannii O.Hoffm. is a beautiful and easy-to-grow plant that can be propagated by seed, cutting, or division. With the right method, the plant can thrive in a variety of locations and provide a colorful addition to any garden.

Diseases
The biggest threat to Sphaeranthus stuhlmannii O.Hoffm. is fungal diseases, which can occur when the plant is grown in humid conditions. Common diseases that may affect the plant include:
- Leaf spot: This is characterized by dark spots with yellowing around the edges on the leaves. Remove and destroy any infected leaves, and avoid overhead watering to prevent the spores from spreading.
- Root rot: This disease causes the roots to rot, leading to a weakening of the plant. The best prevention is to avoid overwatering and ensure that the soil is well-drained. If detected, removing the plant and soil around it and treating with fungicide can help combat this disease.
Pests
Although they are not known to be major pests for Sphaeranthus stuhlmannii O.Hoffm., the following insects may cause issues:
