Our Maris Bard potatoes are showing the benefits of planting early under polythene.
- The soil warmed up under the polythene and the seed potatoes emerged quickly.
- Once the leaf was out the plants grew more quickly.
- These potatoes were planted with only a shallow covering of soil, so that they warmed up more quickly, and emerged sooner.
- This early initial development promises an early harvest! Potatoes are already the size of a marble!
The potatoes are covered over if there is a chance of frost. The leaves can be severely damaged or killed by frost, which would reduce the benefits achieved of early planting under polythene.
