By April in Port Charlotte the dry season has been running for months, the canals sit low and glassy, and any lawn without a working system starts to fade toward straw. Raintree Irrigation Services is the answer to that long wait for June, bringing rain on a schedule to yards that would otherwise hold their breath until the summer storms come back. Its work is easy to picture on a bright spring afternoon: walking a property zone by zone, watching each head rise and fan out, clearing sand from one and turning another so it finally reaches the far side of the lot. The craft lives in those small corrections and in a timer set for the cool hours, so the grass gets exactly what the sky has been holding back. When the summer rains finally roll in off the Gulf, the lawn greets them already green.
