What Prep is needed for hydroseeding?
Preparing your area for hydroseeding is an important step to ensure the best possible outcome. Start by removing all rocks, sticks or other debris from the surface area. Next remove any exisitng grass and/or weeds. Proper landscape irrigation is a must for hydroseeding success, especially for Southern California.
How much top soil is needed for hydroseeding?
Add topsoil to achieve a total topsoil depth of 4-6 inches (10-15 cm), after firming. The soil type should be loamy compost mix. Dark nutrient rich topsoil provides a fertile soil environment for the top 8 inches of soil. If timing allows, conduct a soil test.
Can you hydroseed over dirt?
We do not recommend hydroseeding over an existing lawn. The best practice is to either start over from scratch by completely redoing the lawn, or implement a process called “overseeding.” Overseeding is done with a power rake (you can rent one from a hardware store) and then broadcasting seed.
Do I need topsoil?
Topsoil is basically the top layer of the soil, where everything grows (find out more about the definition of topsoil). So if the soil in your garden is very shallow, or you are making new garden beds, adding or replacing a lawn, or putting in raised beds and need to add new soil, top soil is what you need.
