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.  

The easiest way to remove bushes is first to cut the bush down. You may need to use a handsaw, pruning shears, or a chainsaw for thicker branches. Once you’ve removed most of the branches, you can then cut the base of the shrub as low to the ground as you can get. Then, with a shovel, dig around until you expose the roots. Dig out the roots, being careful not to leave any roots in the soil.

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.

Most rose bushes should not be heavily pruned in the summer since this is the prime growing and blooming season. The best time to trim is typically after the growing season or right before spring, depending on your rose bush variety. However, you can cut away any dead or diseased areas or lightly trim spent blooms during the summer to encourage more growth.
