Farming would be much simpler if nature always behaved itself.
These are ermine moth caterpillars, and they are enjoying our apple trees rather more than we would like. On many farms the response would be straightforward: reach for a pesticide and remove the problem.
We take a different view. Our first instinct is to understand what is happening and whether nature itself might restore the balance. Sometimes predators arrive, populations fall away and the problem resolves itself. Sometimes it doesn't.
Farming organically means accepting that we are working within a living system rather than trying to control every part of it. There are occasions when the crop suffers as a result, and that can have real consequences for a farm business.
The challenge is made greater by a changing climate. Warmer temperatures can favour pests and diseases that were once kept in check, creating new pressures for farmers and growers.
There are no easy answers. But if we want agriculture to work with nature rather than against it, we have to accept that nature occasionally has its own plans.
Listen to William explain what the ermine moth is doing in the orchard, and why we have chosen to let nature take its course.
