Looking for ways to manage weeds in your lawn or landscape? Join us on July 21, 2022 at noon for UC IPM's free monthly webinar to learn about how to control weeds using mostly nonchemical methods. We will discuss why weed identification is important, ways to prevent weed growth, and combining various methods for managing weed problems.
The webinar will be presented by Karey Windbiel-Rojas, Area Urban IPM Advisor and Associate Director for Urban & Community IPM with the UC Statewide IPM Program. Register today to serve your spot!
As always, the webinar will be recorded and posted on the UC IPM YouTube channel within 3 weeks of the live webinar. No continuing education units (CEUs) will be offered for those with California DPR licenses. UC Master Gardeners and others can request CEU approval from their local program coordinators.
Hope to see you there!

Plants
If you have the space, plant an oak tree! While it will take several years for the tree to mature, few plants provide more benefits to nature than an oak tree. One Valley oak tree can provide food, water, and shelter to approximately 350 vertebrate species and over 250 species of insects and arachnids.
Choose plants that bloom at different times of the year, to ensure something is always blooming during the different seasons thus providing nectar sources year-round. Include some plants which produce berries to provide food sources attractive to birds and insects.
Lawns lack variety, thus reducing your lawn space and replacing it with native plants will increase the diversity in your garden. Decreasing the frequency of mowing permits grasses to grow taller, allowing flowers to grow and bloom which would attract bees and butterflies. You can also sprinkle some daisy and clover seeds into your lawn to provide forage plants and flowers for many beneficial insects.
Water
Ponds with aquatic-loving plants can encourage amphibians such as salamanders or toads, or wetland insects such as dragonflies, to visit and set up their homes.
Butterflies engage in behavior called “puddling,” where they stop in muddy puddles for water and nutrients. You can recreate this by filling a terra cotta saucer with soil and pebbles, sink it into the ground and keep it moist. Again, change the water regularly.
Plants and rocks around the water source(s) provide shelter, camouflage, and spots for creatures like butterflies, lizards, or turtles who like to sun themselves near water.
Housing for Bees
Leave the Leaves
Leaving leaves as they drop from your trees and bushes provides food and shelter for a variety of living creatures including worms, beetles, millipedes, larvae of some butterflies and moths, toads, frogs and more. These in turn attract birds, mammals, and amphibians that rely on the smaller organisms as a food source.
Chemicals
One Step at a Time
Changing your garden into a wildlife haven will likely be a step-by-step process over a period of time. Building a garden attractive to wildlife will bring you the enjoyment of watching them and the knowledge you are helping wildlife thrive.
Resources listed provide information for ways to you to build a garden attractive to wildlife.

This year, National Pollinator Week is June 22 to June 28, celebrating the value that pollinators such as bees, birds, butterflies, bats, and beetles provide to the ecosystem.
Pollinators, and natural enemies, can be harmed by pesticides when people are trying to control pests in their gardens and landscapes. Pollinators can be killed or harmed if they are sprayed or exposed directly to a pesticide, and when they encounter pesticide residues in the environment. You can protect pollinators in your garden and landscapes by doing the following:
- Use pesticides sparingly. Many pests can be managed using an integrated approach without the need to apply pesticides.
- Read labels carefully. Proper application of pesticides can reduce pesticide exposure to pollinators and natural enemies.
- Choose selective and nonpersistent pesticides. Avoid broad-spectrum, persistent insecticides such as carbamates, organophosphates, and pyrethroids.
- Select less toxic insecticides when possible. Look for soaps, insecticidal oils, microbial insecticides and botanical insecticides to manage pest outbreaks.
For more information, see this page on protecting natural enemies and pollinators and find recommended practices to protect bees from pesticides.

When you hear the term “pesticide,” what comes to mind? Do you understand what pesticides are and, more importantly, how to use them correctly?
A pesticide is any material (natural or synthetic) used to control, prevent, kill, suppress, or repel pests. “Pesticide” is a broad term that includes insecticides, herbicides (weed or plant killers), algaecides (algae and moss), fungicides (plant diseases), rodenticides, miticides (mite control), and molluscicides (snails and slugs). Even antimicrobial products (such as bleach and sanitary wipes) that kill bacteria on surfaces and chlorine added to pools are pesticides. If a product has a U.S. Enviromental Protection Agency (EPA) Registration Number on its label, it is a pesticide. To make it more confusing, there are some pesticide products that are exempt from registration and won't have an EPA Registration Number.
Home-made mixtures that you make yourself to kill or repel pests are also technically considered pesticides. These include dish soap and water, garlic juice spray, hot pepper spray, vinegar and water, and many other such concoctions.
In future issues of the Retail IPM newsletter and this blog, we will discuss several pesticide topics, including the difference between organic, less toxic, and more conventional pesticides, what are “exempt” pesticides, using pesticides safely, pesticide storage and disposal, and reading and understanding labels.
