Has it rained enough in Pittsburgh?
The last rain heavy enough to soak in fell over a week ago. What has fallen since wet the leaves and no more.
Pittsburgh has had 31mm of rain in the last 30 days. A normal October here brings 95.1mm — and the driest October in the last 30 years still managed 34.5mm. This is drier than anything on that record.

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.
- Established shrubs and treesFine as they are. They draw from far deeper than a dry spell reaches.
