Frequently Asked Questions
How deep should mulch be?
Apply 2-3 inches of mulch for flower beds and around trees. Too much mulch can suffocate plant roots and create pest problems. Keep mulch 3 inches away from plant stems and tree trunks.
How often should I replace mulch?
Refresh mulch annually. Organic mulch decomposes and needs replacement every 1-2 years. Add 1-2 inches each spring to maintain depth and appearance.
What type of mulch is best for landscaping?
Hardwood mulch lasts longest (2-3 years). Pine bark is lighter and better for slopes. Cedar resists insects. Rubber mulch never decomposes but does not enrich soil. Choose based on your needs.
How much topsoil do I need for a lawn?
New lawns need 4-6 inches of quality topsoil. Topdressing existing lawns needs 1/4 to 1/2 inch. For gardens and flower beds, use 6-8 inches of topsoil mixed with compost.
Can I install landscaping materials myself?
Yes, most landscaping materials are DIY-friendly. Topsoil and mulch require spreading and raking. Decorative rock needs landscape fabric underneath. Rent equipment for large projects.
