Many privet varieties are considered invasive, particularly in North America. They can grow quickly, spread into the wild, and push out native species if left uncontrolled. It’s a particular problem for warmer southern states, and some regions even have warnings or regulations against planting certain types of privet. You can reduce (but not eliminate) the chances of privet spreading by cutting its flowers in summer before they develop.

Generally, it is not necessary to remove old mulch before applying a new layer. As organic mulch breaks down, it enriches the soil with nutrients. However, you should remove the old layer if it shows signs of fungus or disease, which can be common in moist areas, or if the total depth is already too thick. Avoid letting the total mulch depth exceed 3 inches, as this can harm plant roots. If you do remove old, disease-free mulch, it can be added to a compost pile.

No, it’s not necessary to remove all the leaves from your lawn—in fact, leaving some behind can be beneficial. While it's important to clear thick layers of leaves that can smother your grass, leaving a light scattering of leaves can help feed your soil while also providing safe winter habitat for pollinators like bumble bees. Leftover leaves will eventually break down, enriching the soil and promoting healthy lawn growth.

Yard waste should be professionally removed at least once per season, particularly during major landscaping projects, fall leaf accumulation, or after severe weather. Regular removal promotes lawn health and maintains a neat exterior.
