Attributes of Greene's mountain ash

Growth Rate

During the active growing seasons of spring and summer, greene's mountain ash exhibits a moderate growth rate. This balanced pace aids in the steady development of its pinnate leaves and intricate corymb-inflorescence. The plant's height increment is noticeable yet measured, ensuring overall structural stability. In summer, growth might hasten slightly as warm temperatures spur further photosynthetic activity, enhancing foliage and flower production.

Toxicity

Greene's mountain ash seeds contain hydrogen cyanide and pose a mild toxicity risk to humans, dogs, and cats mainly through ingestion. Symptoms can include difficulty breathing, dizziness, and nausea. Severe cases might result in convulsions or coma. Immediate medical or veterinary care is essential if ingestion occurs.

Soil Type

Water: Greene's mountain ash thrives in its native habitat with well-draining soil and intermittent rainfall. It is moderately drought-tolerant, needing watering once every 1-2 weeks, allowing soil to dry slightly. Grown outdoors, it requires adequate hydration during the growing season for optimal health.

Fertilize: Greene's mountain ash requires balanced fertilizers in spring, shifting to high-nitrogen in active growth. Apply quarterly, adjusting for growth phases. Benefits include robust growth and improved flowering. In fall, reduce fertilization for winter dormancy. Ensure even distribution to avoid root damage.

Pruning: Greene's mountain ash features vibrant berries and compound leaves, benefiting from early spring pruning to promote healthy growth. Remove dead or crossing branches to enhance air circulation and light penetration. This practice, done during dormancy, reduces stress, encourages growth, and improves aesthetic appeal and berry production.

Propagation: Greene's mountain ash thrives with propagation through sowing in well-draining soil, requiring light for seed germination. Maintain consistent moisture during this phase. After seedlings establish, gradually acclimatize them to outdoor conditions before transplanting to ensure strong adaptation.
