"Cipriano has been working with us for 7 years on maintaining our yard. He has a wealth of knowledge on plants, flowers, and trees. He landscaped our front and back yards, which included fencing and irrigation and drainage. When dealt with a problem he is able to provide workable ideas to solve it…which he has done several times for us. He has a “good eye” for what works best and a real passion for gardening and landscaping."

"I interviewed six companies regarding backyard renovation and I am so happy that I chose Yosi and Rainforest L.A. They transformed our backyard into a relaxing oasis. We were astonished at the transformation. Yosi was so easy to work with, very calm, professional, excellent communication, easy to reach.Yosi provided a detailed bid the very same day we met. He answered all of my questions politely. Yosi's team were friendly, professional, creative, hardworking, and they left our yard spotless every day. We have used many contractors over the years and Rainforest L.A. was the best."

"LA Landscape Sprinkler Pros came out the same day I called about a busted sprinkler valve that was flooding my yard. Erix was quick, clean, and explained everything he was doing in plain English, no BS. Pricing was super fair, and the work was grade A. I’ve already saved his number for the next time I need anything in the yard fixed. Highly recommend!"

Lawns FAQs, answered by experts

Your dog’s diet plays a major role in the amount of nitrogen in the dog’s urine. A high-protein diet leads to higher nitrogen levels because digesting proteins break down the protein and form nitrogen as a result. 

You should also ensure that your dog is drinking plenty of water. Staying hydrated naturally helps dilute nitrogen concentrations in urine—not to mention, it’s better for your dog’s health.

According to the College of Agriculture and Life Sciences, there are over 10,000 kinds of mushrooms, and some are harmful to both humans and animals. However, not all mushrooms are harmful—some feed on thatch and wood, which provides nutrients for grass and plants. 

But unless you’re a mushroom expert (mycologist), it can be hard to tell poisonous mushrooms from non-poisonous. So if you have kids or pets (or both), removing them is the safest route to take.

Mulching leaves with a lawn mower is a great way to reap the benefits of leaf nutrients composting into your lawn without the leaves covering too much of your grass.

Don’t pick up dirt after aerating. Even though it's tempting because soil cores are incredibly unsightly, these cores and the dirt they leave behind are ecologically important. This is what keeps your grass looking beautiful and growing healthily. The soil cores need two to three weeks to decompose, but you can swat them with a rake if their natural shape bothers you.

Several tools exist that can help remove unwanted grass. The one you choose depends greatly on how much you need to remove and how hard you'd like to work. A sod or turf cutter is the fastest method while using a shovel is labor-intensive and much slower. You may also need a garden rake, tiller, and wheelbarrow.
