Just taken in hand the pool at the top opf the water feature. It is overgrown with weed, ivy, and that plant I asked about for quick ground cover, vinca. Well, vinca sure grows, mates, but it is difficult to control. So I have started digging all the rubble etc out of the pool. Now, one dotter gave me one of those lovely lighthouses, a few of you have them. I want it to sit on a little beach. How do I make a beach without it blowing or getting washed away? Any beachcombers out there?
