Help with gravel "pit" in backyard!
A large area of our yard (16x30 feet) is filled with 2+ feet of rough gravel. We live in the city and have a fairly large lot (this area is half our yard). The previous owners have removed soil and added all the gravel as they used this area as a fenced-in dog run for their large dogs.
We would like to move a small apple tree to the area and also would love to start to garden in this area.
I just came in from moving 6 full wheel barrows full of the gravel from a small area and you cannot see any difference at all! The gravel is at ground level (our yard is not higher than other yards), so if we remove it our yard would be a big pit. Plus, the garage backs onto this part of the yard and I would not want to take gravel out from around the garage base.
I am looking for advice of what to do.
Can we add topsoil on top of the gravel? Right now there are also a ton of weeds (manitoba maple babies, huge thistles, gout weed, horsetail weeds, ivy's). Would it be worth adding landscape fabric first? Would the gravel just work it's way up through the soil over time? Could we put a foot of soil and then sod?
Thanks very much!
