🌱 Monday 121 - Function of Assimilation Apparatus
We explored the role of the assimilation apparatus – leaves and needles – in photosynthesis and stress adaptation. Learn how tree anatomy supports vitality, how morphology reflects pollution exposure, and why this matters when choosing trees for urban environments.

🧷 Tuesday 122 - Soil Decompaction
This episode tackled compacted urban soils and how they hinder tree health. We reviewed air spading, vertical mulching, and the use of biochar or compost to restore root zones and improve soil structure.

✂️ Wednesday 123 - Practical Pollarding
Pollarding returns to the spotlight! We discussed how this traditional technique supports sustainable urban forestry, the difference between pollarding and topping, and how to handle neglected trees.

📋 Thursday 124 - Tree Value Calculation
We examined how arborists and municipalities calculate the economic, social, and ecological value of trees. The episode broke down methods like Replacement Cost and Amenity Valuation.

✨ Friday 125 - David Lonsdale
A tribute to David Lonsdale, a cornerstone in arboriculture. We revisited his work on tree pathology, risk assessment, and decay, and celebrated his lifelong contribution to arboricultural knowledge.

🐝 Saturday 126 - Erwinia amylovora
We wrapped up the week with fire blight: the bacterial disease Erwinia amylovora. Learn how it affects apple and pear trees, how to identify symptoms, and strategies for managing and preventing outbreaks.
