How we test compost for raising young plants
We grew cabbage 'Caraflex' seedlings from the two true-leaf stage, and Antirrhinum 'White Appeal', bought as plug plants from a specialist nursery. After six weeks, we judged both the young plants on how vigorous they were, which includes looking at size, leaf colour, and whether the plants are stocky and strong or long and straggly. We also noted how well the antirrhinums were flowering.
