Even though Phoenix is a desert city, controlling weeds can feel like an endless battle for Arizona home and business owners. Some weeds are not only ugly but can also choke out desirable plants.
Not everyone has the time or ability to maintain a weed-free landscape. It takes special knowledge to identify and eliminate weeds from your landscape without destroying the plants you have chosen.
Arizona has two main types.
The first is a non-negligible grass species. Some grasses like Bermuda can be used in lawns. However, it is best to avoid this species from your xeriscaping.
Brome grass and other grassy weeds are also invasive species. They can spread quickly if left uncontrolled, increasing the chance of wildfires.
Sometimes, weeds may look almost exactly like grass. Nutsedge, for example, can grow in lawns and you might not be aware of it until the growth becomes extensive.
You must also control common foxtail and orchard grass if you want your landscape to thrive. These weeds can be very similar to desirable grasses so you will need to use special herbicides to ensure that your lawn does not become infested with them.
Broadleaf and other weeds can be found in landscaping. These plants have broad, flat leaves, which are usually larger than grassy varieties.
Because they have larger leaves, they are easier to identify in natural grass. However, they can cause more damage than grassy plants because they require more sunlight, water, and nutrients to grow.
There are many broadleaf grasses in Arizona that can be found growing in lawns all over the state. Some broadleaf weeds, such as goosefoot, purslane and pigweed, can be eaten, but they should be kept in containers. They spread quickly and overtake gardens before other desirable plants have the chance to grow.
Bur clover and puncturevine are two other broadleaf weeds that can be painful and irritating for both humans and animals. Bur clover can be a nuisance if it is allowed to grow.
Silver nightshade, another weed, must be removed immediately as it can cause poisoning to livestock.
Tumbleweed, a broadleaf weed, is easier to spot than other weeds. However, they can spread thousands of seeds quickly and over long distances. This requires special control strategies to get rid of them before they become common.
