Outdoor plant box
I lack soil space so I built a 1.5x0.5x0.4m plant box and put it on the decking. I drilled ten 6mm drainage holes in the bottom, added a layer of stones then filled with compost from the garden centre.
In April I planted dill, coriander, radishes, and parsley.
however, only the radishes thrived. A few dill seeds sprouted but never grew >5cm. Same for coriander- about 8 of the 30 seeds sprouted. the parsley didn't even bother.
I live in Stavanger in Norway, which although has the worst climate in continental Europe, I am told the seeds I planted ought to grow outdoors.
does anyone know why my dill coriander and parsley might not have grown? planted too early? Too close together? (5cm apart).
