"I called Royal Landscapes and we agreed on a date (03/09/18) to meet to review the job. On March 9th, no one from Royal Landscapes bother to show up. There was no call to cancel or to ask for another appointment. Now to be fair, it snowed the day before so I'm sure it would've been a little challenging to give an accurate assessment of my landscaping needs, but really, no call to cancel or reschedule speaks volumes to me! So I will not be recommending Royal Landscapes."

"M&M did a fantastic job with our new patio. They took down and removed our old deck, framed out the patio and completed the job in only about a week. They took into consideration things we didn’t think about such as size and position of the patio, stairs, and sprinkler realignment. Overall we’re very pleased with the quality and speed of the work and wouldn’t hesitate to use them again."

"I have been very happy with the yard work that Alfredo and his brother have done for me. Landscaping, mulching, mowing, edging my lawn, tree trimming, planting and removal of old plants. They are detail-oriented and very polite. I just hired them to clean my gutters as well! I would highly recommend them!"

"Our front entry steps were cracked and pulling from house. In addition they were originally installed with a bad pitch, water flowed toward home. Derek from sun Viking came to my home for the estimate and after having 3 other estimates Derek was the only contractor who actually identified the actual problem and explained to me that simply veneering the steps would not correct it. I hired Sun Viking primarily due to Derek's knowledge and although the price was more than we budgeted for we went for it (We budgeted $6500 for the job). WE COULD NOT BE HAPPIER!!!! This company exceeded my expectations by doing the little things like pouring footers and rebuilding the steps from the ground up they also installed conduit line for adding step lighting or landscape lights to the homes front later on. His employees were punctual and polite. They explained things to me if I had questions as the job progressed. The finished product is just stunning and we have already received compliments from neighbors. Thank You Derek and the Sun Viking team!!!"

"Alex is a very hard worker but beyond that he is a very well self taught hard landscape architect . He is creative and inspiring. I initially hired him to put up a fence. He did such a great job I hired him to redo my pond. It came out beautifully. I then hired him to redo my poolâ s patio area and erect a small brick barrier between the flower beds and the patio and once again it was beautifully done. He also put in two walkways that charmingly meander through the forest behind the pool house. We are now planning to put in a bocce court . On a scale of one to ten Alex is a twelve. I highly recommend him. PS his prices are very competitive so much so that he was the low bidder on these projects. He is the best landscape architect I have ever hired and a great guy to work with."

Landscaping FAQs, answered by experts

The best time to plant a privet hedge is autumn, ideally October or early November. Fall is the best time to plant privet hedges because young plants need plenty of water to jump-start their growth, and it typically rains more during this season. However, you can also successfully plant privets in the spring.

The best time to plant is between spring and autumn. Springtime weather is typically mild and is when nurseries start to bloom. When the summer weather arrives and it’s hot out, it’s best to avoid planting bare-root plants, but you can still plant many in-container varieties. The first sign of fall is another great opportunity to plant biennials if you live in southern states, or a lovely vegetable garden up north.

If you choose to leave gaps between your pavers, you can grow some ground cover plants between them for an organic feel. Look for plants such as creeping thyme, dymondia, jewel mint of Corsica, or clover.

DIY home gardening can be relaxing, joyful, and cost-effective. From mowing your lawn to planting your own flower beds, there is a wide variety of gardening tasks that you can do yourself to make your yard look beautiful. If you’d rather spend your time not in the dirt, or if you’d like someone to take care of your plants for you, calling a professional gardening service is best. They can give you a workup of what services you’ll need and how often to schedule them.

Palm trees are relatively easy to grow, especially when planting different varieties in their native habitats. While regular watering is crucial in the first couple of months while the palm develops a strong root ball, palms typically require minimal maintenance once they’re established. You’ll need to prune palm fronds once or twice per year to keep it in tip-top shape.
