I have a very ugly concrete patio that puts you off going in the garden. I have been lucky and have two pensioners fixng it up for me. I am shocked at how much and how hard they have worked. The main man age 70 and the other 72 don't stop working even in the rain. They are trying to make my garden easy to look after. I have listened to them and love what they have done so far. They have suggested ; gravel ,stones or chippings to go over the top, I am unsure of the best type , I would like to have garden furniture outside and for it to be comfortable, I don't have pets or children so that makes it easier..... They have said if I don't like gravel all over I can move it and put something different in the middle and still have the gravel or stones surrounding the area. My question is what would be the best choice of stone or gravel or slate in the interim. There are boarders made from sleepers as you will see in the photographer.......... What would be the best option ? I think I could pave over the concrete at a later date.....I would appreciate any advice.
