I’ve been asked a lot about my approach to sowing seeds, and it seems an opportune time to write about that. Though some seeds are best started off in pots (tomatoes, aubergines, celery), the majority of my seed sowing is done in module trays.

A module tray is a tray with individual compartments or modules in it. A decent-size tray will measure 335 x 515mm and have between 80 and 150 modules. They are made from tough plastic, so they can be used again and again. The beauty of a module tray is that the roots of seedlings are kept apart, which means you don’t upset them when you are transplanting them.
