Garden Soil

Soil Type

Water: Tree wormwood is a drought-tolerant plant well-suited for arid environments. It requires watering every 2-3 weeks and thrives in well-drained soil. As an evergreen, it can adapt to different climate zones, making it an excellent outdoor choice.

Fertilize: Fertilize tree wormwood with a balanced fertilizer in spring, using a high-nitrogen formula during growth. Apply quarterly, using a teaspoon per plant, and water afterward to mitigate root burn. Adjust frequency in winter, and ensure even distribution, as over-fertilization can harm tree wormwood.

Pruning: Tree wormwood is a perennial shrub with aromatic, silver-grey foliage that thrives with careful pruning. Perform pruning in early to late winter to remove dead branches and improve airflow, enhancing both appearance and pest control. Consult horticultural guides for specific methods.

Propagation: Tree wormwood is a perennial herbaceous plant that flourishes in well-draining soil and full sun. Propagate via semi-ripe cuttings from healthy shoots in a perlite and peat mix. Ensure proper moisture and warmth for root growth, and acclimatize young plants before transplanting.
