I had this misfortune of cattle getting on my lawn after i gave its its final mow, there is alot of hoof marks and sliding marks what can i do to repair the lawn especially at this time of the year, spade and repair the sod or sand /soil.

I sowed hardy perennials in late Sept/early oct. some have germinated and are tightly packed in the pot. I think it is too late to prick them out. Will they survive in my plastic greenhouse? I have each pot in a ziplock freezer bag which is open now, but I can close over the winter. I have overwintered older seedlings(from summer sowing) in plastic boxes with snap lids before. this is my first attempt at autumn sowing. Should I do anything else?

I have a photinia Red Robin hedge since august 2010. I havnt prunned it yet cos its thriving,new growth past two weeks. when should i cut it back?

I bought a propagator and took over 20 Hydrangea cuttings and they have now rooted....when do I increase airflow in propagator or move them to larger pots in my (new) greenhouse?

Can I plant potatoes next year in the plot i used this year?

Is it too late to put nitrogen on my lawn, also I have a green beech hedge 90% of it is very strong but 10% directly under a large tree is weak. Is there any feed I can put on this 10% to help them.

My lawn is 20 m x 20 m . On three sides there is a gravel path and on the fourth is a flower border . On the sides with the path, about 18 inches into the the lawn it starts to slope down to the gravel preventing me from getting a nice defined edge to the lawn .I have seen lots of public gardens with a similar arangement but the lawn stays level and doesnt slope away at the edges . Any explanation ?

Might you advise on a remedy or cure for hole shot in a laurel hedge, as whilst the hedge fairly full of foliage, it would seem that it is not triving either.

Can I divide Oriental Poppies and Astilbe now?
