Sissoo

Care & Maintenance

Once established, sissoo is surprisingly drought tolerant, but 'established' takes 2-3 years of deep, infrequent watering every 1-2 weeks in summer. It prefers well-draining soil and will develop root rot if planted in heavy clay or low spots where water sits. Skip the fertilizer unless you want even faster, weaker growth. Full sun is non-negotiable.

Common Issues & Threats

• Invasive surface roots: This is the tree's biggest liability. Sissoo roots travel aggressively, often 50+ feet from the trunk, and they lift sidewalks, crack driveways, invade drip lines, and have been documented getting into sewer pipes. If you plant one within 20 feet of hardscape or utilities, plan to deal with root damage.
• Branch failure in wind: The wood is brittle relative to its rapid growth rate, and in haboob or monsoon conditions, large limbs drop without much warning. A poorly structured sissoo over a patio or parked car is a genuine risk.
• Sissoo borer (Agrilus sp.): This flatheaded borer attacks stressed or declining trees, tunneling under the bark and girdling branches. Look for D-shaped exit holes, dieback starting at branch tips, and bark that crinkles and peels. Once a tree is heavily infested, recovery is unlikely.
• Aggressive suckering: Sissoo sends up root suckers, sometimes appearing in your neighbor's yard or through cracks in paving. This can make removal complicated because the root system keeps sprouting for years after the main trunk is gone.

Pruning Guide

Prune in late winter before new growth, and focus on establishing a strong central structure early. The mistake most people make is letting sissoo grow unpruned for the first few years because it looks fine. By the time it's 15 feet tall with co-dominant stems and included bark, you're looking at expensive corrective work or accepting ongoing risk. Remove crossing branches and anything with a tight V-crotch. Avoid heavy pruning in summer, which stresses the tree and opens wounds during peak borer season.

Did You Know?

Dalbergia sissoo is in the legume family, which means it can fix atmospheric nitrogen through root bacteria. In its native range across India and Pakistan, the dense, oily heartwood is one of the most prized furniture and guitar-making woods in the world. The same tree people rip out of their Phoenix yards for tearing up driveways has been commercially harvested for centuries for high-end woodworking.
