"Emerson saved my life and yard. I hired another Landscaper and he worked for me about a year and a half. One day on his own he decided to rip out my shrubs without asking and left gaping holes in my yard. Emerson came to my rescue and helped to get my yard back in shape. He is efficient, responsible and gave me a fair price. I would recommend Emerson Landscaping."

Landscaping FAQs, answered by experts

It is for the purpose of protecting them from hail because you’ll be removing it soon after the threat is over. However, plastic or vinyl tarps aren’t recommended as a long-term way of protecting your plants from frost because they’ll trap too much moisture inside, which is actually not a good thing for your plants. But in the short term, it’s fine to use even an overturned garbage can to protect a plant from hail.

In most cases, wait three to five days to repot or relocate a plant from a greenhouse or nursery. That way, your plant has time to recover from any shock during the move and adapt to the conditions in and around your home. Some hearty plants may not need as long, and delicate plants might need several weeks. You should ask the professional at your nursery for a recommended timeline. Consider asking about an initial watering schedule to help stimulate root growth and promote a healthy plant.

Hedges can be trimmed in many other shapes than the standard square shape. They can be cut into spiral, cone, and sphere shapes. However, cutting and maintaining these types of shapes is much more challenging. There are metal frames that you can purchase to place around the hedge to make it much easier.

Monkey grass isn’t too picky when it comes to light conditions: It needs sun but prefers partial shade. While it can tolerate full sun, it thrives in environments with partial shade (around four to six hours of sunlight per day). The black mondo grass variety is the most tolerant of heat from direct sunlight.

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.
