In the shadow of all the scientific information offered thus far,my contribution may be viewed as simplistic but I believe it to be relivent. The question was raised "what is topsoil"? In context of landscaping and gardening,topsoil is exactly what it sounds like, soil that has layed on the surface for many years. The author or speaker generaly uses the term to differentiate between topsoil and fill dirt. Many people don't realize the difference when they recieve subsoil and pay for topsoil. You couldn't raise an umbrella in subsoil if you were sitting on on a bag of fertilizer. Dump truck owners are paid by excuvation contractors to haul dirt away from projects to dispose of it. About 90% of dirt that needs to be moved is subsoil. Where projects like golf courses involve horticulterists from start to finsh,topsoil is usually moved aside for use when final grade is done. If a gardener has extra space, buying enough soil to cover the extra space 1' deep then grow cover crops and till in amendments is better than gambling on new soil from a vendor. Two years can yield soil suitable for use in leveling turf,starting raised beds and other use where topsoil is required. I am impressed with the results of burying a large dead maple, free wood chips from the electric power line clean up and 50 bags of fall leaves picked up at the curb 5 years ago. So impressed that I am alowing free disposal of limbs in the wake of our ice storm in early December. As soon as I have enough leaves and find chipped wood , I will bury it and wait for the bounty. It will require lots of time and sweat with a shovel and wheelbarrow,,,,,,,,NOT,,,,,,I have a tractor.

I meant to say soil with lots of organic matter, not organic soil. I make a big and wide hole, maybe one yard in lenght and width and 1/2 a yard deep. I fill out this hole with the best soil I can buy at any garden center...I mix in some cow manure, chicken manure and any other rich matter I find...make sure you mulch heavily after planting the vines. Fernando, in Brasil, commercial passion vines are replanted every couple years. Here in Florida, I do the same, I replant my vines every two years, maximum every three years. Nematodes is a big problem in sandy soil. I hope this info will help you. Where are you located?

Theparsley ha ha yeah we've already had a few salad meals and there's nothing like the taste of fresh grown greens. darth_veeder, I am keeping out the crazy insane rabbits, I first learned that I had rabbits when we first moved in, they showed me by chomping down and killing three of my young blueberry bushes. Then when I planted my bare root apple trees they went after the trunk. I put up tree guards quickly. Then when I set up the garden, I knew the trouble would come so I wanted to put up that chicken wire with no possibility of them jumping over it, might be over done with height but it's fine. Right now I have peach trees from seed growing they nipped them too, so I have clear plastic forks guarding those for now but will be fencing them soon. If you can't tell I hate these rabbits! I won't kill them unless they cross the line, the line is my garden, they cross it they will be dinner. Theses rabbits are not that fearful of people or dogs.
