lawn maintenance, under poor conditions
im after some advice with what to do with a patch of the garden.
i have a square garden surrounded with 6ft high fencing (more or less), and about 15% or so of the back end of the grass gets pretty much no sun at all, the soil is highly acidic (ph 5 when tested), the soil type is heavy clay and consequently there is moss there. i did my best to reduce that, upon moving into the house the moss and weed problem was horrific, hardly any of the lawn was actually grass! but the problem still remains in that last patch somewhat. i will attach a picture when i get home later if i can.
im wondering if there are any ideas on what i could do with the area, or whether i could keep the grass and just work harder to make it better. the whole lawn is surrounded by about a foot width of gravel border. i have a cammelia in the left corner (adolphe audusson) which gets sun from mid afternoon, and a sorbus tree in the other corner (planed slightly inwards of the corner) which due to its height gets a bit of sun all day. the cammelia has grown nearly double its size since autumn, and the sorbus has grown also but is quite slow. it has not flowered/fruited yet either (last year).
i mowed the lawn for the first time this year at the weekend, and plan to rake it then pitch fork (aerate?) it tonight. is it then advisable to use a combined lawn feed and moss killer?
any other help would definitely be appreciated! thanks.
