Soil and allotment maintenance

Adrian used to double dig everything as he thought that was the right way and enjoyed the exercise. Over time he has transitioned to managing some areas of his plot using a “no-dig” strategy. Increasing awareness about beneficial soil ecosystems which help keep a good soil structure and function better when less disturbed led him to install deep raised beds 6 or 7 years ago. He uses the raised beds strategically for plants that need regular attention, as their height makes it easier on the body.

Another adaptation has been to invest in a large netted cage structure for pest control against birds and rabbits. This excludes unwanted visitors, but is still experimental as the partitioning will reduce crop rotation from 4 to 3 years. Adrian uses netted tunnels for protection against dreaded carrot flies, and has vinegar spray at hand to deal with flat-worms. While avoiding chemicals as much as possible, he occasionally has to resort to slug pellets.

Adrian recommends new growers to wait 3-4 weeks later than recommended sowing dates given in popular TV and radio programs such as Gardeners Question Time. He warns that it’s easy to get caught out by sunny, warm weather the region often experiences in March. These bouts are usually followed by a return to cold weather which kills off the plants. Growers also need to avoid planting too early in greenhouses or under glass outdoors. These plants tend to shoot up quickly and need planting out while it’s still too cold. Despite the later sowing time, most plants catch up, although Adrian recommends new growers to stay away from butternut and corn which are challenging in Aberdeen’s short growing season.
