Growing Native Plants

Care for Young Native Plants

Your native plants are ready to plant. As for any nursery stock, when you bring these plants into the landscape, they need careful attention during their establishment period (usually two to three years).

Planting

The default for natives is to plant them where they’ll have good drainage, though many riparian and meadow plants tolerate more slowly draining  habitat.

Do not add any amendments when planting native plants. You can work a bit of full decomposed homemade compost into the soil completely surrounding the area, not just the hole. But avoid doing this for chaparral plants, as they naturally live in soil where they take up nutrients very slowly.

Dig the hole twice as wide and as deep as the plant’s container. Build up a little mound of soil in the center of the hole, for the plant to sit on. Many native plants are quite sensitive to planting height. Make sure the crown is ½-inch above soil level, once you’ve tamped in the soil.

As with all garden planting, plants suffer less transplant stress if they are planted in the cooler parts of a warm day. Soak the newly planted plant thoroughly; some say this is the deepest watering you’ll ever give your new plant.

Build a small berm, away from the plant’s crown but close enough to the plant to help keep water around root ball. (In rainy seasons, adjust berms to allow water to drain away.)

Much Ado About Mulch

Many plants do better when mulched. When you mulch around your plants, you’re reducing water evaporation, keeping soil cooler, and controlling weeds. The type of mulch you use should correspond with the plant’s natural habitat. For plants native to many of our local habitats, such as lower conifer forest and foothill woodlands, use wood chips or other wood mulch. For plants native to rockier habitats such as chaparral, however, use small, light-colored rock; these help reflect sunlight and are less likely to cause crown rot if they accidentally come in contact with plants.

Place mulch about three inches away from the base of the plant. Inspect this seasonally, as wind and gravity may cause some shifting. One thing I’ve learned since becoming active in Redbud is the importance of not covering all bare earth with mulch, however. Most species of native bees are ground nesting, and they need open soil in which to nest, so be sure to dedicate leave them some open ground, perhaps seasonally covered with wildflowers or under larger shrubs not bothered by weeds.

Resources on Establishing New Native Plants

Even if the plants you are taking home are drought-tolerant California natives (which most are), they still need water and care for the first couple of years. Because most plants do best if they are planted in the fall, when you purchase plants in the fall, the best option is to keep them in the shade and give them regular water until the weather cools and/or after the first couple of rains. Then you can transplant your young plants into their permanent homes. Because riparian plants want year-round watering, you may buy and plant them anytime.

Once in the ground, your new plants will need to be deeply watered weekly until rain takes over the job. Keep their root balls moist not soggy for the first three months.

Then they will need watering once or twice a week during the hot months for the first couple of years until they have developed a more extensive root system. In general, stop watering bulbs when their leaves start to yellow. Let them go completely dormant from the first year; otherwise, they’ll rot. Just a few species, such as Leopard Lily and Camassia, like some summer moisture.

After that, low-water plants should do fine with little or no water. Some species are completely drought-adapted and giving them any summer heightens their risk of disease. Oaks need no summer water; they’re susceptible to a fungus that grows only when warm and wet. So, in natural conditions, that fungus isn’t a threat; it becomes an issue only when people water under oaks during summer. Some low-water and drought-adapted plants are fine, and might even look better, if they get a deep soak of summer water monthly. Be sure to water before a period of hot weather rather than during it. Imagine what might happen to a parched plant if its roots reached hot water!

Wetland and riparian plants will need regular water through every summer, and most coastal species will need watering once or twice every two weeks during our hotter, inland summers. Remember, Calscape is good source of information about water needs of species, and which plants are particularly sensitive to summer water.

Ways to Water

The simplest way and most meditative way to water is to hold a hose. Of course, it’s hard to give plants a deep soak using this method, and it takes a lot of time, over and over, plus you’re fighting with hoses.

Otherwise, you’ll want to install drip irrigation for most circumstances (except grasslands and meadows). We recommend using drip tubing with pre-installed pressure-compensating emitters. Encircle the plant with the tubing, placed out just at the outer edge of the rootball. As a plant grows, you can easily move the tubing farther from the plant, encouraging root growth. Individual emitters, formerly popular, are easy to install, but they get clogged easily, which too often allows plants to dry up and die without anyone noticing.

To establish grasslands and meadows, use overhead watering, such as sprinkler heads (the newer rotor heads are quite water efficient) or oscillating sprinklers

Thinking Different for Container Gardening

• Selecting native species that are likely to succeed in a container
• Using a potting mix that suits the plants you’re growing
• Choosing a container that is a good size for the plants you’ve selected
• Choosing a container made of a material that suits the climate where you live and the siting in your landscape (how much sun it gets)
• Deciding on a way to water your container so your plant will have the reliable water it needs, bearing in mind that plants in containers need more water than plants in the ground

Resources for Container Gardening with Native Plants

Articles, presentations, and other resources about gardening with native plants sometimes include more than one topic covered on our Redbud website. We’ve included some of the most useful here, in hopes you’ll find this list convenient. If you have suggestions for additional resources, please let us know, at nativeplanthelp@redbud-cnps.org.

Recorded Redbud Presentations

We’ve been recording our Zoom presentations and posting them on our Redbud YouTube channel. Here are some that are particularly relevant to gardening with natives.

What Makes Native Gardening Special? Explore how gardening with California native plants differs from gardening with regular nursery plants, with Redbud member and Nevada County Master Gardener Chrissy Freeman. This presentation covers how native plants, particularly local natives, contribute to the ecosystem, from the soil to insects to birds and other fauna. See special landscape design considerations and opportunities that using native plants in your landscape offers. Learn about gardening best practices specific to natives. Chrissy shares photos of a variety of native-plant gardens and the plants that live in them.

Learning Even More About Your Favorite Local Native Plants Using Calflora. Calflora’s Executive Director Cynthia Powell discusses new Calflora tools for CNPS Calflora users. Calflora’s plant database hosts over 2 million plant occurrences, some of which come directly from Redbud CNPS members (including prolific Jeff Bisbee and Hannah Kang!). Cynthia covers Calflora’s new iNaturalist data feed, plant photo project, planting guide, population monitoring tools, email alerts, and entering Chapter checklists into Calflora.
