Lettuce is often grown between rows of slowing-growing vegetables or as a catch crop
, using ground before or after another crop - and for that reason is ideally suited to small gardens.
The best catch crop
is the radish, which can be harvested within a month.
Nitrogen-rich, readily mineralising biomass of all catch crop
species (with straw removed from the soil) incorporated into the soil markedly increased (0.
If you have to deal with a situation where you feel a flush of nutrients (large amounts of fresh green material or manures incorporated into the soil) creates the danger of leaching and potential nutrient loss, plant a "catch crop
" (rye planted as an over-winter crop is a good example) that aggressively "scavenges" or "sops up" excess nutrients, preventing their loss from the soil and retaining them for future availability when the catch crop
2Clear away early crops such as potatoes, peas and broad beans and make catch crop
sowings of beetroot, lettuce and short horn carrots.
We keep the stores on grass, but we also do a catch crop
of stubble turnips on ground that's going to be maize the following year.
This can also be sown now to provide a late autumn catch crop
You can also underplant crops such as runner beans that are grown on poles as it can be up to six weeks from planting in late May before the beans block out the light underneath, giving you time to get a catch crop
of salad leaves germinated, grown and harvested.
Salad vegetables of all kinds are the perfect catch crop
, and you should be able to get two or more pickings of lettuce, radishes, rocket and spring onions from between the rows of slow veg.
Lettuce can often be grown between rows of slower-growing vegetables or as a catch crop
on ground before or after another crop.
A catch crop
is one that matures before the ground is occupied by another crop - radish is the one with which we are most familiar.
Grants are also available for catch crops
, rainwater harvesting, field drainage and livestock removal from high risk fields.
