Ent and allergy garden city The concept of an Ent and Allergy Garden City is based on the idea that certain plants and trees can help reduce allergies by producing pollen that is less allergenic or by attracting beneficial insects that help control pests. For example, plants such as lavender, mint, and sage are known to have anti-inflammatory properties that can help reduce allergy symptoms. Similarly, trees such as oak and maple produce pollen that is less allergenic than other trees. An Ent and Allergy Garden City would also incorporate the principles of forest gardening, which is a type of permaculture that mimics the structure and function of a natural forest. In a forest garden, edible and medicinal plants are grown in layers, with tall trees forming the canopy, smaller trees and shrubs forming the understory, and herbs and groundcovers forming the forest floor. This layered approach not only maximizes the use of space but also creates a diverse and resilient ecosystem.
