Walk your yard during an irrigation cycle and watch the beds. If lawn spray heads are throwing water across your shrubs and flowers, your beds are getting the wrong water in the wrong way — and in sandy soil, that costs more than it does inland.
What spray does wrong in a bed
It waters leaves, not roots. Spray lands on foliage, and in our humidity, chronically wet leaves invite the fungal problems coastal gardeners know too well. Meanwhile the water that does reach soil arrives fast and drains fast — the sandy-soil problem at bed scale.
It waters everything equally. A bed holds plants with different needs, plus mulch and open soil. Spray soaks it all alike, feeding weeds in the gaps and floating mulch out of the bed during long cycles.
Why drip wins in sand
Drip lines deliver water slowly, at the soil surface, directly at each plant's root zone. In sand, slow delivery is the whole game: water arrives at a rate the root zone can hold, instead of racing past it. Foliage stays dry, weeds between plants get nothing, and evaporation losses drop, which shows up on the water bill.
Drip also plays well with our salt-and-sand plant strategy — salt-tolerant plantings established with drip settle in faster because the moisture is steady instead of feast-and-famine.
The practical setup
Beds move onto their own zone with a pressure-regulated drip line, separate from lawn spray zones, so each runs on the schedule its plants need. Converting existing beds is routine work for us — usually a single visit. It's all part of the irrigation service; the free estimate will tell you exactly what your yard needs.
