1-2 days
per week
Based on the weather for the past two weeks and the forecast for the next two weeks, we recommend watering 1-2 days per week for the next 14 days.  

This recommendation is only applicable to the watering schedule you received from your Slow the Flow sprinkler consultation. If you've already received a Slow the Flow consultation but no longer have the watering schedule, please email  water@resourcecentral.org   and we will resend your schedule.

April Showers Bring May... Weeds?
It’s officially weed season in Colorado! Luckily, there are a few “natural” approaches to help you manage any weeds that have already popped up, and prevent new ones from sprouting.
First off, the best control for weeds is a healthy landscape. Limiting amounts of bare soil should effectively reduce future weed problems. A thick healthy lawn for example, doesn’t allow much sunlight beyond it’s canopy, starving any potential weed seeds of this essential growth factor! Remember: Weeds are survivors by nature, so don’t be afraid to fight dirty. Try the following approaches to help you tackle weeds in your lawn or garden:

Mowing:
Mowing is a helpful method to limit weed seed production.
  • Mow bluegrass, buffalograss, tall fescue, fine fescue and ryegrass at 2 1/2 to 3 inches during the summer. The higher mowing height produces a healthier grass plant. Crabgrass and other annual grassy weeds are much more common and aggressive in lawns that are mowed less than 2 inches.
  • Mow often enough so that no more than one-third of the grass blade is removed in a single mowing. Letting grass grow tall and then cutting it back to a low height reduces turf density, allowing weed seeds to germinate and grow more easily. A lawn may require mowing every three to five days during the spring and early summer.
  • Aerate the lawn at least once a year to reduce compaction and to control thatch.

Hand Weeding:
Frequent hand removal of annual weeds is a time consuming but effective tool if done before flowering.
  • The most important rule of weeding: Don’t leave the roots behind. If you yank only the leaves, weeds will grow back. Grab the weed close to the ground and pull straight up. Do it right the first time, you’re done. (Unless pieces of the root break off in the ground. It happens.)
  • Weed after it rains. They’ll come up more easily when the ground is moist.
  • If the soil is dry, or if your weeds are too small to pull by hand, use a hoe or other garden tool. Keep the blade sharp for a fast cleanup in large areas.
  • Off with their heads. If you can’t get weeds up by their roots, chop their heads off every now and then. That will prevent them from setting seeds, and with any luck, they’ll eventually die.
  • Don’t leave bare spots. Weeds love to move in, so space plants as recommended on their tags or labels. Mulch unused beds, or sow a cover crop at the end of the season.

Horticultural Vinegar:
Horticultural vinegar is a natural way to get rid of weeds, especially if hand weeding isn't cutting it. Nurseries and landscaping suppliers sell this synthetic-herbicide-alternative, which contains about 20 percent acetic acid, compared to your kitchen vinegar's 5 percent.
  • Apply vinegar when there is no rain in the forecast so it has time to soak into the plant without risk of washing off.
  • Spray like you would any other weed killer. Spray the vinegar directly on the target plant. Be careful not to spray non-target plants (like your grass).
  • Do not overspray! You just need to coat the leaf, not soak the soil. The vinegar is meant to kill the "canopy" (green part of the plant) so it can no longer photo-synthesize.
  • You'll likely need more than one application.

Mulching:
Don't fight lawn weeds where grass won't grow!
If you've tried to grow grass in an area more than once and failed, it might be time to consider a landscaping alternative. Shady areas or areas surrounding trees are notoriously tricky spots for grass growing, but various weed species have figured out how to fill these voids. Because weeds need (some) light and warm soil to survive, mulching is a preventative measure that suppresses annual weeds by limiting light required for weed establishment.
  • To use mulch as a natural weed barrier, you need to put down a 2- to 3-inch layer. That's enough to keep most weed seeds from sprouting.
  • According to CSU extension, you don’t need to use any landscape fabric under mulch, as this might contribute to lower garden plant rigor.
  • If you're mulching around trees, shrubs or roses, avoid piling the mulch against the bases of the trunks and stems. Remember to replenish the mulch annually to maintain a 2- to 3-inch layer, as mulch will break down over time.


Although we prefer a more natural approach to weed management here at Resource Central, you may find yourself needing bigger backup in your battle for a weed-free lawn. Before using any chemical products, correctly identify the weed(s) you’re targeting and read the product label. The type of product you use should be determined by the type of weed you’re using it on, and application instructions may vary accordingly.

Happy weeding!
Seeds Galore!
Over the course of one year, a dandelion can produce 15,000 seeds, purslane, 52,300, pigweed, 117,400 and mullein can produce over 220,000 seeds. The viability of a seed, that is how long a seed is able to persist in the soil, is also a factor in how much havoc they'll wreak. Dandelion seeds do not have long-term viability in the soil, but purslane and pigweed seeds may persist in soil for 20 and 40 years, respectively. Mullein seeds may persist in the soil for up to 100 years! No wonder weed management is such an ongoing battle.
