The optimal time to tackle thorn bush removal is during late fall or winter when the bushes are dormant. The plants are less active during this time of year, making it easier to prune and remove. Additionally, you can more easily see what you’re cutting since there are no leaves.

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.

Depending on the method you choose to remove grass, it may or may not matter whether the grass is wet or dry when you perform the task. A dryer lawn will be easier to negotiate with a sod cutter, especially if you're not planning to reuse the turf. However, using a shovel by hand might be a little easier if the ground is slightly damp but not so much that it sticks to the tool.  

It’s possible to over-mulch leaves. If the leaf mulch is thick enough that it’s blocking and smothering the grass, that’s a problem. Ideally, you should still be able to see the grass when you’re done mulching to ensure its ability to continue growing. The solution is to make another pass at the top layer of leaf mulch to collect some of the top layer.
