Gardens to compensate for increased building around me
My garden is below sea level. This means that the water course is high. We are working on raising the garden a few inches to try to bring the surface above the water course.
Over the years a few more houses have been built around us and there are a lot of people with water treatment plants (for anyone not familiar with these, they clean sewage water and release cleaned water into the surrounding ground). Though approved through the required agencies I can't help thinking that the reduction in green space and the increase of water being pumped into the ground will affect the general level of the water course in the immediate area.
I was inspired by an article I read recently on flooding whereby oak trees were being planted to alleviate flooding. Oak trees had been found to be helpful to hold water when the ground was too wet so it was thought that many oak trees together could help to prevent flooding.
To my point then. I wondered if I could use planting in my garden to similar effect. Oak trees being big, I'm looking for any alternatives that might be known to 'hold' water in times of excess water in the ground. The plants would need to be robust through summer too when the water course is lower and they may need to tolerate drier roots.
At present I'm looking for any suggestions regardless of size.
I have an oak tree on the property boundary and that does appear to be the area where the ground is least waterlogged. So I'd like to think that thoughtful planting would work in reducing the extent of the waterlogging.
I can't help thinking that I'll give plants a better chance of survival if I know they'll be suited to the conditions too!!!
