Stubborn Weeds in Phoenix - Titan Landscaping Services

Keeping a commercial landscape weed-free in Phoenix is no easy task. The heat, dry soil, and occasional rain create the perfect environment for weeds to thrive. They push through lawns, invade groundcovers, and spread across granite areas faster than you’d expect. That’s why weed control services are essential to keeping your landscape in top shape.

Titan Landscape Services knows how frustrating weeds can be. That’s why we provide weeding services, landscape maintenance, and commercial landscape maintenance to stop weeds before they spread. If they’ve already taken hold, post-emergent treatments will knock them out fast.

Weeds That Take Over Phoenix Lawns

Not all weeds are equal; some are worse than others. They grow fast, take over lawn alternatives, and can be tough to control. Here are three of the biggest troublemakers in Phoenix:

  • Burr Clover: Spreads fast and produces tiny burrs that stick to your clothes, pets, and shoes.
  • Cheeseweed: A deep-rooted weed that’s tough to pull by hand.
  • Oxalis: Looks like clover but spreads aggressively through seeds and underground runners.

These weeds are stubborn, but post-emergent herbicide treatments can wipe them out before they take over your property.

What Are Post-Emergent Treatments?

Post-emergent herbicides eliminate weeds that have already sprouted. Unlike pre-emergent herbicides, which stop weeds before they grow, post-emergents work on weeds that have broken through the soil.

They come in two main types:

  • Selective Post-Emergents: These target specific weeds but leave grass and other plants unharmed. Great for lawn maintenance where weeds like Burr Clover or Oxalis invade.
  • Non-Selective Post-Emergents: These kill any plant they touch. They’re great for gravel areas, sidewalks, or large weed infestations in non-landscaped zones.

We use post-emergents in the form of liquid sprays, granules, or spot treatments, depending on the type of weed and location. If you’re dealing with a weed invasion, post-emergent treatments are your best defense.

How Post-Emergent Treatments Work

Post-emergent herbicides don’t just kill weeds at the surface; they go after the entire plant, including the roots. That’s what makes them so effective in commercial landscape maintenance.

Here’s why they work so well:

  • Kills Weeds at the Root: Post-emergents don’t just burn off the leaves; they reach deep into the root system to stop regrowth.
  • Stops Weed Spread: Many weeds, like Cheeseweed and Oxalis, spread through seeds and runners. Post-emergents stop them before they take over your lawn alternatives or groundcovers.
  • Fast and Long-Lasting Results: You’ll see results in days, and treated weeds won’t return as long as there is proper maintenance in the area.

If weeds have already made an appearance, post-emergent herbicides are the best way to get them under control. But if you really want to keep your property weed-free, the secret is stopping them before they sprout.

Other Ways to Keep Weeds Under Control

Weeds are relentless, but they don’t have to be a problem. A combination of pre-emergent herbicides, hand-pulling, and mechanical removal can make a huge difference.

Apply Pre-Emergent Treatments in Early Spring

The best way to fight weeds is to not let them grow in the first place. Pre-emergent herbicides make a barrier in the soil that stops weed seeds from sprouting.Early spring is the perfect time to apply pre-emergents. Here’s why:

  • Rising Nighttime Temperatures: Warmer nights signal weed seeds to start germinating.
    Pre-emergents stop this process before it begins.
  • Spring Rain Helps the Treatment Work: Rainwater pushes the herbicide into the soil,
    making sure it reaches the seeds before they sprout.

Using pre-emergents and post-emergents together as part of a weed control services plan is the best way to maintain a weed-free property.

Hand-Pulling & Mechanical Removal

Some areas need manual weed control. Hand-pulling and mechanical weed removal are great for high-traffic locations or areas where chemical treatments aren’t an option.

  • Hand-Pulling: Great for small infestations and shallow-rooted weeds. Removing weeds before they go to seed keeps them from spreading.
  • Mechanical Removal: We cut weeds at the root using specialized tools to keep them from growing back. This is especially useful in areas with lawn alternatives and delicate plants.
