Q How often should I sow quick-growing veg, such as lettuce, so that I get a continuous harvest instead of periods with nothing to harvest followed by gluts?
A When Which? Gardening magazine trialled different sowing timings, we found that all the veg did well when we waited until at least half the previous seed had germinated. The length of the time that it takes to reach this point varies according to the veg and the weather.
