Tree and arbor care services

Trees are the framework of a commercial landscape — and the first thing visitors notice when one fails. Our arbor services keep that framework healthy, safe and shaped, from seasonal trimming to storm response and disease treatment.

Seasonal trimming and shaping

Fall is our major tree-trimming season, coordinated with leaf cleanup and storm preparation. Winter is when we cut back and shape hedges and shrubs so they do not overgrow their planters — scaling them back once lets us shear and shape them lightly all year instead of hacking them back periodically.

Storm response — ready before the wind

Santa Ana winds arrive every October, and trees between mid-rise buildings can see winds accelerated to twice their speed by the venturi effect. Our supervisors carry chain saws and tree-guying and staking equipment during wind season, so a tree that blows over during the night is dealt with first thing in the morning. Properties below canyons or along the Santa Ana riverbed get particular attention. Read our autumn column.

Root disease: phytophthora

Waterlogged clay soils can invite phytophthora root rot — chiefly a threat to trees and palms, which it can kill if untreated. Where breather tubes or french drains exist beside the root ball, we pump out excess moisture and inject fungicide. Where they do not, we can install a drain system, or inject and drench the root ball directly. Read the spring column for the field notes.

Trunk injection protection

For systemic pest protection — including lerp psyllid on eucalyptus — we inject directly into the trunk, so the treatment travels the tree’s vascular system and protects it from reinfestation later in the year. Timing is everything: injection works best in March–April, when sap flow carries the systemic throughout the tree. See pest & disease control.
