This summer, a quiet experiment is taking shape on the estate. It’s a collaboration between Professor Andy Moffat, local gardener Phil, and Jonathan Graham, CTO of Steward of Things. Together, they’re exploring how young trees respond to different watering methods in urban environments.

Back in May, three sets of trees were planted: one crab apple and one hazel in each group. These trees were chosen for their ecological value and their ability to support pollinators, especially in areas connected to the UK’s B-Line corridors.

Each set is being cared for in a different way:

• One set is watered manually by the estate’s tree warden, alongside other scheduled tree care.
• Another set is left to nature, with no intervention.
• The third set is monitored by a soil moisture sensor, which triggers watering only when the soil drops below a critical level set by the device.

The UK has faced a prolonged drought this year, with many regions still feeling the effects. This trial offers a timely look at how different approaches to tree care can support resilience, especially in urban areas where resources are stretched and climate extremes are becoming more common.

Throughout the summer, the team will be observing growth, leaf health, and soil conditions. The goal is to understand which methods help trees establish most effectively, and how technology can support local stewardship without replacing the human touch.

Updates will be shared as the season unfolds. If you're nearby, take a walk past the crab apple and hazel trees and see how each one is doing. Each tree is part of a bigger story about care, climate, and community.
