Propagation of Galium trichocarpum Nutt.
Galium trichocarpum Nutt. can be propagated by both seeds and cuttings.
Propagation by Seeds
Seeds of Galium trichocarpum Nutt. can be collected when they mature in late summer or early fall. The seeds should be sown in a well-drained soil mix in the fall or stratified and sown in the spring. Cover the seeds with a thin layer of soil and water gently. Keep the soil moist until germination occurs, which typically happens within three weeks to a month.
Propagation by Cuttings
Galium trichocarpum Nutt. can also be propagated through stem cuttings. Take 3- to 6-inch-long cuttings from the parent plant in late spring or early summer, making sure each cutting has at least one node. Remove the lower leaves from the cutting and dip the cut end in rooting hormone. Place the cutting in a well-drained soil mix and water thoroughly. Cover the pot with a plastic bag to create a greenhouse effect and keep the soil moist. The cutting should root within four to six weeks.
Disease and Pest Management for Galium trichocarpum Nutt.

Mites: These pests are microscopic but can cause significant damage to the plant by feeding on its leaves and creating a distinctive mottled appearance. Mites can be controlled by spraying the plant with a strong jet of water or by using a miticide.
Caterpillars: The larvae of moths and butterflies can cause significant damage to the plant by feeding on its leaves. They are easily controlled by handpicking or by using Bacillus thuringiensis (BT).
Diseases
Rust: This fungal disease appears as orange or yellow pustules on the leaves. Rust can be controlled by removing infected leaves and spraying with fungicide.
Powdery mildew: This disease causes a powdery white coating on leaves and can reduce plant vigor. It can be controlled by removing infected leaves and spraying with fungicide.
Root rot: This disease is caused by a soil-borne fungus and can lead to wilting and stunted growth. It can be controlled by improving soil drainage and by avoiding overwatering the plant.
By being vigilant and proactive, one can prevent pesky pests and diseases from harming Galium trichocarpum Nutt.
