Controlling Weeds, Watering Plants, Preparing for Monsoon Season

Welcome to “At Home With Tom and Sandy.” This month, Tom and I thought we would get in the weeds.

Tom: Sandy, I suspect you already have a plan for this month’s column.

Sandy: Hi Tom, yep, you know me, always planning, thinking and dreaming. I asked Josh Crothers, owner of Prescott Landscape Professionals, and Chris Welborn, owner of Vicente Landscaping, to join us. We are getting into the summer months, and I want our readers to get great information regarding their landscape during this time of year.

Tom: Good thoughts. Welcome, guys. So, it is June. What sage advice do you have for folks about summer care for our landscaping?

Chris: Hey, Sandy and Tom, thanks for asking us to be here. One of the main events of the summer homeowners need to pay attention to is weed control.

Josh: Agree wholeheartedly. The coming monsoon season typically triggers a weed bloom that people need to be ready for.

Sandy: Oh boy, isn’t that the truth? How do you both recommend dealing with the weeds, beside putting a hex on them to not grow?

Josh: Probably the best preparation for weed control is by applying a “preemergent.” That is a product that will stop the growth at the seed level before the weeds can germinate.

Chris: Yes, Josh is right on. Getting the preemergent down is key. Doing that before the rain is best.

Sandy: I understand that commercial applicators of the preemergent need to be licensed by the state.

Josh: Correct. The Pest Management Division has an educational and testing procedure in place. It can be up to a two-plus year process to obtain licensing.

Chris: Several of the more professional landscape companies in this area have that license. The reason for the control is that we are essentially handling a product that can be harmful if not applied correctly. I am proud to say that Josh and I are both licensed and understand the importance of applying a chemical properly.

Tom: If I did not have a preemergent applied, and have weeds growing in my xeriscape yard, can I apply a weed killer? And while I am at it, the follow-up question: Is there a difference between a preemergent and weed killer?

Chris: First question, yes, you can apply a weed killer. After they start to grow you can apply the weed killer. Two problems with that approach, first is the likelihood of inconsistent application, and the chemical is nasty stuff, and if you aren’t properly suited up to apply, you can become contaminated. Also, now you must pick up all the dead weeds.

Josh: When any of these products are applied incorrectly, they have the potential to contaminate ground water.

Sandy: Too little and ineffective application, the weeds thrive. Too much, and there is an impact on the environment. Sounds like a job for the pros like you guys. What else should our readers be doing in June?

Josh: June is typically the hottest and driest month. Plants can get stressed if not watered sufficiently.

Chris: Plants should be nice and green this time of year. If they start turning yellow, that is an indicator they are stressed.

Tom: Should we just water them more?

Josh: Yes, supplemental watering in conjunction with your irrigation might be needed.

Chris: And, along with that, you should consider fertilizing them as well.

Sandy: Good advice! There are so many different fertilizer types out there. How do we know what to use?

Chris: Typical fertilizer for plants is characterized by the three main ingredients with the chemical periodic table symbol. They are Nitrogen, Phosphate and a K for Potassium: NPK.

Josh: There are different ratios of the three in different fertilizers. Arguments can be made for using different ratios at different times of the year. I suggest a balanced approach. 10,10,10 which coincides with the percentage of the three primary ingredients Chris mentioned.

Sandy: Should we just put the suggested amount around the plant and leave it or do you suggest watering in the granules?

Josh and Chris: Water! Water! Water!

Tom: About watering, you both mentioned supplemental watering as needed during hot, windy and dry times. Should that be done by hand, or should I just increase the flow from my irrigation system?

Chris: Either way really. Sometimes it is simpler to water by hand.

Josh: I agree, watering by hand in the evening also gives you more control over the amount of water you use.

Sandy: With the monsoon season right around the corner, what other advice do you have for our followers?

Chris: Check out your drainage systems. Check your gutters, underground pipes and surface swales, making sure they are free of anything that might block them or cause erosion in the rest of your yard.

Josh: Folks should also look at their plant depression areas around the plant base to be sure they are retaining their form and positioned to capture as much rainwater as they can.

Chris: There are several types of water catchment systems. You can have tanks to collect or use a more passive surface system.

Tom:  Should I also monitor my automatic irrigation system during the monsoon, dialing it down if we get rain?

Josh:  If you have a rain gauge and the latest rain measures a half inch or more, then you can decide how to moderate the frequency.

Sandy: Lots of folks use this time of year to plant new trees and shrubs. Is that OK?

Josh: Plant away!

Chris: Yes, Plant away. If your yard is frequented by wildlife, you may want to look at some plant types that do not attract animals and pests.

Sandy: I don’t want my yard to be a salad bowl for wildlife, for sure.

Josh: When you do plant, you may want to supplement the irrigation watering until plants are established.

Tom:Good advice all around. I am grateful to learn about the need for a state license to put down preemergent. To our readers, you can verify that a company is properly licensed to apply preemergent materials through the office of pest management, www.opm.azda.gov.

Sandy: Hiring licensed contractors, hmm, where have I heard that before?

Chris with Vicente Landscaping, and Josh with Prescott Landscaping Professionals, thank you both for taking the time to help our readers stay informed.
