The height of a planting bed depends largely on the soil underneath and the type of plants.
Ideal height for raised garden beds.
The depth is important since you need the garden.
Planting in raised beds also dramatically increases the yield of the garden too because the soil used in them can be made ideal for rearing plants.
Very handy if you live in a colder region.
In addition the beds tend to warm up earlier in the spring extending the growing season.
The most popular height for raised beds is 11.
When you make a raised garden bed the height is purely down to your and your garden s needs.
Optimum size for raised beds raised beds are best kept to a maximum of four feet 1 2m wide.
For a vegetable garden to succeed your raised bed should have at least 8 inches of soil depth which means the bed itself needs to.
Raised beds typically range from 12 inches to 18 inches with a maximum of 36 inches in height.
Beds against a wall or fence should be about 2 3 feet 60 90cm wide as you ll only have access from one side.
Deeper beds hold more soil and thus more moisture reducing watering needs.
Bury any turf removed in making the beds in the lower levels of soil in the bed to enrich the soil as it decays.
In general the worse the underlying soil the deeper you will want a bed to maximize the amount of good soil available to plants.
Ideally a garden bed should be no more than 1 2m 4 wide if it is accessed from both sides as this width allows an adult to reach just past the centre from any side giving optimum accessibility to the gardening area.
This will reduce their watering needs.
The height of raised garden beds tends to be anywhere from six inches to waist high.
Raised gardens require the addition of high quality gardening soil because they are often built in areas where the ground is poor for gardening.
Most raised beds range from 6 to 12 inches with some as high as 36 inches.
And more depth means more room for roots to grow.
When building raised beds on top of hard surfaces ensure a depth of at least 45cm 18in but ideally 60cm 2ft so that plants can root deeply.
This makes it easy to reach the middle of the beds without stepping on the soil.
For best results there should be another 12 or more of good soil below the bed.
