Building a garden on top of asphalt is not as difficult as you might guess . As long as you have enough sunshine and the bit is not too low , so water wo n’t puddle under the garden , you should have some success . You might find that you actually prefer it to a ground stage garden since the grime line is higher and you have to bend over less . A lift seam can also do away with the peril of contaminated soil leaching chemical substance into the garden .

Step 1

situate a land site where the garden will get from five to eight minute of sunlight per Clarence Shepard Day Jr. . Look overhead and check that that there are not trees overhead that are now barren of leaves but will flick out and shade off your garden during the summer . Take the time to look at your yard after a heavy rainstorm to make certain that water supply does not pool where you plan to jell your garden .

Step 2

Place the social structure that will hold your garden together in place in the spot you have designated . you could purchase kits from home melioration centers or build your own from wood suitable for outside condition . There is no motive to ground it to the footing , as the weight of the soil will have everything in position . check that it sits horizontal surface so that you do n’t have water runoff problems during the pelting . Use sturdy shims or bricks that are substantial enough to hold the weight of the raised bed .

Step 3

Measure your reinforcement structure is to set the sizing of your garden . Cut out section of sens textile to place on top of the asphalt . This will keep your soil from drain out of your garden when you have a laborious rain . Make it 6 inches bigger on all four sides so that it becomes a fond lining . Do not use plastic or any fabric that does not provide easy weewee drainage or the roots of your plants might decompose .

Step 4

sate up your raised garden structure . Start with the Mary Jane cloth , revolve about it and allow the sides to come up on the interior of the structure . Shovel in about two or three inches of pea gravel to keep the dirt above the land . fill up the rest of the seam with good timber garden land to about 18 inches thick . This will be deep enough for larger plant like tomatoes and peppers . Of naturally , you could make it shallower if you are just planting flower or smaller plants like lettuce and herbaceous plant .

Step 5

Water the bed so that the water system set out draining out of the bottom . This will settle the soil and get rid of any melodic line pocket that might have rise . you could add more soil if the grade drops too abject and re - water until the soil level is just an inch or two below the edges of the social structure . Allow the lift layer to enfeeble and settle for about 12 hours before planting your seeds and works .
