If possible, schedule watering cycles in the early morning,
when water pressure is at its highest. This allows ample
time for water to soak in while evaporation and wind drift
are low. Evening watering can leave foliage damp for too
long, leading to mildew under some circumstances.
Ask your local nursery or garden center for a schedule
suited to the special weather and soil conditions in
your area.
