Seed & start
Direct sow

The raised bed in the first heatwave: when shade helps β and when it hurts
The first 30-degree week arrives earlier every year than you'd think. What in the raised bed really needs shade, what the sun can handle, and why a shade net is sometimes the wrong move.
First harvest week β radishes out, lettuce in
This week the first things come out of the raised bed β radishes are ready, cut-and-come-again lettuce is harvestable, some herbs need their first trim. And while you harvest, it's the moment for the next succession sowing. Here's the plan for the next 14 days.
