What that means for what you grow
- Pots and hanging basketsWorst hit, and first to suffer. Very little soil, fully exposed, and nothing to fall back on — in this weather they can empty in a day.
- Salad and leafy vegShallow-rooted and quick to bolt once they run dry. First priority of anything in the ground.
- Beds and bordersA long soak that reaches the roots is worth more than a daily sprinkle, which only wets the surface and is gone by lunchtime.
- LawnsLeast urgent of the lot. Brown grass is dormant, not dead, and comes back within weeks of proper rain.
- Established shrubs and treesFine as they are. They draw from far deeper than a dry spell reaches.
