Problem My new front garden seems to have pools of water on it for a good few hours after rain.
Background I've just had the front garden redesigned, leaving us with a brand new area for planting and a new driveway. The area where the garden now is is our old driveway. The old tarmac drive was broken up, but left. Underneath the tarmac is solid chalk. Retaining walls have been built around this to effectively create a raised front garden to a height averaging 0.8 - 1.5m deep.
The infill is made up of a lot of rubble from the building works, like tarmac, bricks etc. Then there is some average quality soil, and finally a good 400mm of fresh graded topsoil.
The whole garden is to be used as a bed for planting topiary, shrubs etc - no lawn. We have planted lots of buxus already. 24 hours after watering, the soil still feels very sticky. Is this due to poor drainage? With all that rubble at the bottom, some ungraded soil (200mm perhaps?) and then 300-400mm of topsoil, I thought I would have good drainage.
Can anyone explain why I would be seeing puddling of water after rain? Is this something I should worry about, or is this just usual for topsoil as it starts to compact down after delivery.
Any help and advise appreciated as I really don't want all this money to go to waste due to a mistake I've made so early on. So would rather try and rectify now if there is anything that needs doing.
