A window flower box should be deep enough that there’s room for a wide selection of plants and the required amount of soil and gravel. Standard flower boxes are 8 inches deep and 8 inches from front to back. Larger is better to increase the variety of plants in the box, but you could run into stability issues as it increases in weight.

The best size rock for your landscaping depends on the design, as different boulders serve different purposes. If you want to group boulders to create a natural-looking cluster, you’ll need a range of sizes. Otherwise, here are some suggestions:

• Small boulders (smaller than 12 inches across): Best for landscape edging and fire pits 

• Medium boulders (12–24 inches): Best for retaining walls and water features

• Large boulders (more than 24 inches): Best as standalone landscaping features, steps, or walkways.

Of course, you can mix and match sizes to create a unique display.

A scattering of leaves won’t pose a problem through the winter, but a thicker layer of leaves may not decompose before the first frost and can instead weigh down your grass and harbor mold or fungi. A thick layer of leaves also cuts off light and air that grass needs to grow. That’s why we suggest removing thick leaf layers within several days if possible. If your lawn goes dormant over the winter and snow has already caught up with you, then remove the leaves in early spring before your grass-growing season starts so your lawn can thrive.

The best type of rock for landscaping depends on your specific project and needs, as different rocks are suited for different applications. For covering large areas or creating an affordable driveway, consider gravel, but note that it can wash away in flowing water. For water features, river rocks are a good option. Flagstone and cobblestone are ideal for aesthetically pleasing patios and walkways. If you are building a stone wall, fieldstone or small boulders are up to the task. Large boulders and landscape rocks work well as statement pieces, to fill empty space, or to indicate boundaries, but be mindful that they can overwhelm smaller gardens. The best approach is to first define your landscaping project and then select the rock type that best fits that purpose.
