Has it rained enough in Basel?

The last rain heavy enough to soak in fell over a week ago. What has fallen since wet the leaves and no more.

Basel has had 16.2mm of rain in the last 30 days. A normal September here brings 89.4mm — and the driest September in the last 30 years still managed 42.4mm. This is drier than anything on that record.

What it means

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.
