Service / Tree & shrub care

The most valuable plants on the property are not the grass

Deep-root feeding injected below the turf layer, plus dormant oil and seasonal insect and disease control for ornamentals, hedges and established trees.

Why it matters

Tree & Shrub Care

A mature live oak is worth more than everything else in the yard combined, and it is competing with turf for water and nutrients in the top few inches of soil — a competition the grass usually wins. Deep-root feeding puts nutrients below that layer, where tree roots actually are. The rest of the program is seasonal: dormant oil while the plants are asleep, then targeted treatment for the scale, aphids, mites and fungal problems that show up on a fairly predictable schedule around here.

What is included

Six things in the price

Deep-root injection

Liquid feed injected six to eight inches down on a grid through the root zone, below where turf roots take it first.

Dormant oil application

A winter oil treatment that smothers overwintering scale and mite eggs before they hatch — the cheapest pest control of the year.

Scale, aphid and mite control

Targeted treatment when populations appear, not on a blanket schedule. Your technician inspects at every visit.

Fungal and disease treatment

Common ornamental diseases identified and treated, with pruning recommendations where a treatment alone will not fix airflow.

Plant health inspection

A written note on anything declining, including the ones we cannot fix — sometimes the honest answer is that a tree is failing and you should get an arborist out.

Iron and micronutrient correction

Chlorosis in high-pH soil treated directly rather than waiting for a soil amendment to work its way down.

The season

Visit by visit, in order

Timing shifts by a few weeks north to south, and your local owner adjusts to the actual weather. Soil temperature decides the schedule, not the calendar.

Dormant, January to February

Visit 1 — Horticultural oil

Applied while plants are dormant and temperatures allow. Smothers overwintering scale, mites and aphid eggs before the season starts.

Early spring, March

Visit 2 — Deep-root feed

The main annual feeding, injected through the root zone. Timed as the plants break dormancy and can use it.

Late spring, May

Visit 3 — Insect and disease

Inspection and targeted treatment for the first wave — aphids, lace bugs, early fungal issues on the plants prone to them.

Summer, July

Visit 4 — Scale and mite control

Peak season for spider mites and armoured scale, especially on stressed plants. Treated where found.

Fall, October

Visit 5 — Fall deep-root feed

Second feeding as top growth stops and root growth continues. This is the one that pays off next spring.

What you get

On paper, every time

Everything below is part of the standard program. If a visit skips something, the service note says why.

  • Five scheduled visits across the year
  • Two deep-root injection feedings, spring and fall
  • Dormant oil application in winter
  • Written plant health notes after each inspection
  • Referral to a certified arborist for anything structural

Questions

Asked often enough to answer here

Do you prune or remove trees?

No. We feed and treat. Structural pruning and removal is arborist work, and we will refer you to a certified one rather than pretend otherwise.

Is deep-root feeding worth it over granular?

For established trees competing with turf, yes — granular fertilizer largely feeds the grass on top. For young shrubs in beds without turf competition, the difference is smaller and we will tell you so.

Can you save a tree that is already declining?

Sometimes, if the cause is nutritional or a treatable pest. If it is root damage, girdling or trunk decay, no amount of feeding fixes it, and we would rather say that in month one.
