We’re approaching the end of cooler weather and transitioning to a festive time of barbequing, pool parties, and a prime growing season for trees and plants. Now is the last opportunity to prepare your yards and be ready to take advantage of the summer growing season.

Our nursery pros have put together the best landscape tips to get your yard ready for the summer months. Take a read through our collection of advice and ensure your yard is ready to grow and look amazing all summer long!


Here is your May landscape & garden care to-do list:



Sprinkler system in grass lawn

When temperatures begin to rise, it's crucial that you keep an eye on how your trees, shrubs, and other plant material are responding to the heat. This will also help you notice any minor issues and fix them before they become a problem.

Always remember to use a deep watering method on your trees and shrubs so water reaches the entirety of the root system. Short and shallow watering sessions are usually ineffective, preventing water and nutrients from reaching the whole root system of your trees and plants, and resulting in a waste of water.

Long and slow watering sessions are best because it allows the water to penetrate deep into the soil. Not only does this help the tree right away, but it also helps in the long-term development of the root system, and it can make a tree less susceptible to drought. 

For more information on deep watering practices, check out our watering guides to better understand how to take care of your irrigation settings.



mulch in landscape moon valley nurseriesNow is a great time to ensure the sensitive trees and plants in your yard are well-equipped to stay cool through the summer. The most efficient way to keep the soil around your plants moist and cool is to apply a layer of mulch around them. Adding a few inches of mulch will help you reduce how much water you’ll need to use because the mulch keeps the roots cool and retains moisture for longer periods of time.

Our Premium All-purpose Mulch is available at any Moon Valley Nurseries location.

Additionally, certain varieties of trees are susceptible to sunburn, and almost all species of trees could benefit from some extra solar protection on their trunks, at least while they are still young. Our nursery pros recommend covering the trunk with a protective tree wrap. Younger trees are more prone to sunburn than mature specimens, so be sure to cover their trunks this month to ensure healthy trees this summer.

Protective Tree Wrap is available at any Moon Valley Nurseries location.

pulling weeds from yard moon valley nurseriesYou might notice that spring weeds are beginning to die off. Unfortunately, summer weeds are just about to start popping up! The first solution to ridding your yard of weeds is to manually rip them out by the roots. Keep in mind, that as the heat of summer starts to set in, weeds multiply more rapidly to the point where it can be challenging to stay ahead of removing them.

Moon Valley Nurseries stocks many different products that can help you eliminate the weeds that are currently growing and also provide you with products to stop them from coming back.

Nobody wants to spend their summer constantly pulling weeds out of their landscape. The best form of weed control is pre-emergent. Pre-emergent solutions get a hold of the weed problem before it ever begins. Much like the name states, these herbicides stop weeds that have not yet emerged through the soil by creating a barrier around the seeds and not allowing them to germinate.

Any of our Moon Valley Nurseries locations carry all the pre-emergent products you need for your weed prevention plan. Our Nursery pros will help you pick the right ones for your yard!

By creating strong and healthy root systems, your landscape is able to better handle adverse conditions with reduced stress from the environment. We recommend fertilizing monthly, March through October, for most trees. 

We carry fertilizers for everything in your landscape, from shade trees, flowering trees, and palms to fruit and citrus.

As the temperatures rise, nitrogen will be harder to use in high doses due to its potential burn factor. It is good to use some nitrogen-enriched fertilizer now to give your lawn a boost in growth and development that will keep it looking great through the summer.

May is a great time to plant in Arizona. With the summer growing season right around the corner, many trees and plants will take advantage of the longer days and extra sunlight to push out more growth.

Below are some of our top recommendations for the best trees to plant this month, but feel free to reach out to our nursery pros and landscape designers for further suggestions of what to plant, care advice, and design tips. You can even schedule a free landscape design consultation with one of our pros to plan out the best plants for your yard and flag out exactly where they’ll go!

Ficus nitida

Ficus nitida Indian laurel

The Ficus ‘Indian Laurel’ is one of the best medium to large shade trees you can find! In fact, this near-perfect tree loves to grow where there’s plenty of full sun exposure. Of course, one of its big selling features is its wide-spreading canopy, which features beautiful, lush evergreen foliage that adds beauty to any environment. We love to plant them on any landscape that could benefit from its generous shade capability. When properly placed around a home, its canopy can provide enough shade to help cool the home, which can lead to lower utility bills and a more comfortable indoor environment during those hot days.




Phyllostachys aurea

Golden bamboo

Golden Bamboo is cold hardy, heat tolerant, and adapts well to sun and partial shade environments. One of the great things about this bamboo variety is that you don't have to live in the tropics for it to thrive. It's a small to medium bamboo species that features beautiful golden stems and thick growth, making it an attractive option for homeowners in search of a privacy hedge. In fact, it's one of the best choices for creating a lush living wall because of its fast growth and tropical appearance. The golden shoots contrast beautifully with the dark green evergreen foliage.
