Urban gardening

My garden is limited to a few square yards. I wanted so badly to plant some roses, but after I started digging, I found out it was concrete just after a few inches. So I decided to get some pallets and plant my plants over the yard. Afterwards, I saw how the grass surrounded the pallets and I thought it didn't look nice. So I went to some stores to find out stone prices. The idea in my mind was this kind of zen garden with round white rocks but they were so expensive. So I ended buying this cheaper stones... I like the color and the size is not so bad. After some few working hours, this is the result. Later when the roses arise I will show you them.
