- 2 Cold-stratify seeds outdoors or in a fridge over winter
- 3 Sow in free-draining seed compost and keep in a cold frame
- 4 Be patient - germination can take up to two years
Materials needed:
Semi-ripe cuttings
Mature (hardwood) cuttings taken in autumn also root well outdoors over winter.
- 1 Take semi-ripe (half-woody) cuttings about 15 cm long in July
- 2 Remove lower leaves and dip the cut end in rooting hormone
- 3 Insert into free-draining cutting compost
- 4 Keep humid and shaded until roots form

What Diseases Commonly Affect Glaucous Dog Rose?
TLDR: Glaucous Dog Rose is susceptible to 6 known diseases. Monitor regularly for early detection.
Black Spot
Black spot is the most serious fungal disease affecting roses, caused by the fungus Diplocarpon rosae. It is characterized by dark circular spots on leaves that progress to yellowing and premature leaf drop. The disease thrives in humid and cool conditions, especially early in the growing season.
Powdery Mildew
Powdery mildew is a common fungal disease caused by various fungi species including Erysiphe, Podosphaera, Oïdium, and Leveillula. It affects over 10,000 plant species worldwide. The disease thrives in warm, dry climates with high humidity and appears as a distinctive white powdery coating on plant surfaces.
Rust
Rust is a common fungal disease caused by fungi in the order Pucciniales that affects a wide variety of plants. The disease gets its name from the characteristic orange, yellow, or reddish-brown pustules that appear on leaves, resembling metal rust. This obligate fungal parasite requires living plants to survive and can cause significant economic losses in agricultural crops.
Aphids
Aphids are small, soft-bodied, pear-shaped insects (1/16 to 1/8 inch long) that feed by sucking nutrient-rich sap from plants. They reproduce rapidly and can quickly weaken plants, causing distorted growth and transmitting plant viruses. Aphids come in various colors including green, black, red, yellow, brown, and gray. They secrete honeydew, a sticky substance that attracts ants and encourages sooty mold growth.
Meaning & Symbolism
In European folklore and heraldry, wild roses such as the dog rose symbolize love, beauty, and simplicity; it was the stylised rose of medieval heraldry and remains the county flower of Hampshire, England.
