Cotoneaster, ferns and Cotswold stone
A rather difficult to access corner of my garden was a bit of a nightmare when it came to cutting one particular bit of hedge. Anything of value growing there would get damaged by my feet and the process of gathering up the hedge clippings.
This year I decided to do something about it and in the process make a positive feature of the rather dark, northfacing corner.
I moved out plants ( which regularly became overwhelmed with weeds anyway) and cleared the ground.
I built a little curved one brick high wall (engineering bricks for durability) with a shallow foundation around my ferns.
I then covered the ground with weed suppressing membrane and a thick layer of Cotswold stone chippings.
I can get to everything now and will be able to liven up the whole area with some colourful pots.
My qualms and query:
I'm wondering now whether the limestone content of the Cotswold stone will leach through to the ferns and cotoneaster and have a detrimental effect on them.
I know it is too late to backpedal but I might be able to rectify the pH artificially if it becomes a problem.
Can someone please tell me what are the acid v alkali implications of Cotwold stone chippings?The ground has always been fairly shaded and damp and the ferns always loved it, but I also wonder whether the hedge might need more water now the ground is covered with membrane and chippings.
