White Alder is a deciduous tree with spreading or ascending branches and downwards pointing tips. It has coarse tooth dark green leaves. It is very fast growing to 50' to 90' with a 40' spread. It is very heat and wind tolerant and it is native to California. It is found statewide along streams below 5000 ft. -Cornflower Farms
Dig hole, insert plant slightly higher than soil grade. Disturb root ball very little. No amendments, just native soil. No fertilizers. Backfill the hole .Water lavishly. Mulch top of soil around plant in a 4' diameter circle. - Bert Wilson Las Pilitas
