A working field guide, built from observation.

Much of what is diagnosed as a nutrient deficiency on coastal properties is an availability problem. Shell fill, limestone base, and irrigation water can hold soil pH above the range in which iron and manganese remain accessible, and the planting shows chlorosis while the nutrient is physically present in the soil.

Our practice is to test before feeding, note the result in the estate record, and treat the underlying condition — organic matter, water quality, and targeted amendment — rather than repeating a fertilizer cycle that the soil chemistry will not permit the plant to use.

Salt arrives two ways: airborne drift carried on prevailing wind, and soil salinity from tidal influence or irrigation. Symptoms differ. Drift burns leading edges and windward foliage; soil salinity produces uniform marginal necrosis and stunting that fertilizer will not resolve.

We record where each condition occurs on the property, then match planting and pruning to that exposure profile. A species that fails on the windward corner may perform indefinitely twenty metres behind a hedge line, and knowing which is which prevents repeated replacement.

A zone that reads as functioning at the controller can still be delivering unevenly: a clogged nozzle, an obstructed head, pressure loss at the end of a long run, or a schedule inherited from a different season. The planting reports the difference long before the equipment does.

We observe zones running rather than reviewing them on paper, note coverage and pressure behaviour against the planting they serve, and keep the result in the record so a recurring pattern becomes visible over seasons instead of being rediscovered each year.

By the time a specimen looks poor, the causal condition is usually established: compaction restricting root development, planting depth, chronic saturation from a drainage path, or root damage from earlier work. Treating the visible symptom seldom changes the outcome.

Our approach is to establish the condition first, correct it where correction is possible, and document what was found. Replacement is a decision of last resort, taken knowingly — not the default response to a plant that looks tired.

The Gulf Coast year is not neutral. Hard pruning close to storm season, feeding into a dormant period, or installing seasonal color ahead of a heat window all produce predictable disappointment regardless of the quality of the material or the labour.

We plan the sequence in advance and hold it in the estate record, so seasonal work is carried out at the point in the year when it is likely to succeed, and so an owner or manager can see what is scheduled and why.

Irrigation controllers, lighting runs, Lutron scenes, pumps, and drainage paths are usually installed correctly and then modified quietly over years. Without a record, every fault begins with reconstruction: which zone, which controller, which run, which change.

Keeping the layout current — including corrections made after installation — turns documentation into a working tool. It shortens diagnosis, reduces unnecessary excavation and vendor visits, and makes a handover to a new manager or owner straightforward.
