You have made the decision. The design is done, the plants are in the ground, the mulch is spread, and your brand-new native garden is installed. Now comes the hardest part: the first year. I want to set realistic expectations, because the first twelve months of a native garden look nothing like the final result, and that gap between expectation and reality is where most people get anxious and start making mistakes.
The First Rule: Sleep, Creep, Leap
There is an old gardening saying that perfectly describes how perennials and native plants establish: first year they sleep, second year they creep, third year they leap. This is not just a cute rhyme — it is a biologically accurate description of how native plants invest their energy.
In the first year, most of the growth happens underground. Your new Blanketflower or Little Bluestem may look exactly the same above ground as the day it was planted — or even a bit worse. But beneath the soil surface, it is building the extensive root system that will sustain it for decades. Colorado native plants are famous for root-to-shoot ratios of 3:1 or even 5:1. A plant with six inches of visible growth above ground may have two to three feet of roots below. That underground investment is what allows native plants to survive our droughts, our temperature swings, and our fierce Front Range winds.
Do not judge your garden by its first-year appearance. The real show starts in year two and gets spectacular by year three.
Watering: The Establishment Period
This is the most critical topic for first-year success. Native plants are drought-tolerant once established, but they are not drought-tolerant on day one. The transition from a nursery pot to your garden soil is stressful, and the plant needs consistent moisture while its roots grow out of the rootball and into the surrounding soil.
For the first growing season, I recommend watering deeply once or twice per week, depending on temperature and rainfall. Deep means the water should soak down at least six to eight inches into the soil. Light, frequent watering — a quick sprinkle every day — is counterproductive because it keeps the roots shallow and dependent on surface moisture.
The easiest way to water a new native garden is with drip irrigation on a timer. We install drip systems with most of our projects, set to run two to three times per week for 30 to 45 minutes per zone during the hottest months. The timer takes the guesswork out of it. As the season progresses into fall, reduce watering gradually. By October, you should be watering only if we are in a significant dry spell.
After the first full growing season (spring through fall), most established native plants can have their irrigation frequency reduced by 50% or more. By the third season, many installations can go without supplemental irrigation entirely, relying only on natural rainfall and occasional deep watering during extreme drought.
Weeding: The Unavoidable Reality
Weeds are the number one challenge in first-year native gardens, and I am going to be honest: there is no way to avoid them entirely. When you disturb soil (which happens during any planting), you expose buried weed seeds to light and moisture, and they germinate enthusiastically. Your new native plants are small, widely spaced, and growing slowly. Weeds are fast, aggressive, and they know how to exploit the open space.
The good news is that this is temporary. As your native plants mature and fill in, they form a dense canopy that shades out most annual weeds. By year three, a well-designed native garden requires very little weeding. But in year one, plan to spend time on hands-and-knees weed patrol.
I recommend weeding every two weeks during the growing season. Pull weeds by hand when the soil is moist — after rain or watering. Get them before they set seed. The most common first-year weeds in Fort Collins native gardens are kochia, purslane, cheatgrass, lambsquarters, and bindweed. Learn to identify these and pull them on sight.
Do not use herbicides in a new native garden. Even targeted applications of broadleaf herbicide can damage young native perennials. And pre-emergent herbicides will kill your native plants' seedlings along with the weeds. Hand weeding is tedious but it is the only safe approach for the first year.
Mulch Management
Your mulch layer is your best friend during the establishment period. A three-inch layer of wood chip mulch retains soil moisture, suppresses weed germination, moderates soil temperature, and feeds soil biology as it decomposes. But mulch needs management.
Check your mulch depth monthly during the first year. In areas where it has thinned to less than two inches, add more. Keep mulch pulled back two to three inches from the crown of each plant — piling mulch against the stems can cause crown rot, especially in wet springs. If you see mushrooms growing in your mulch, that is a good sign — it means the soil food web is active and breaking down organic matter.
What About Fertilizer?
In almost all cases, no. Do not fertilize native plants. This is one of the most common mistakes I see. Native plants evolved in lean, nutrient-poor soils. Adding fertilizer — even organic fertilizer — stimulates fast, floppy top growth at the expense of root development. It also gives weeds a competitive advantage and can reduce flowering in plants like Coneflower and Penstemon that bloom best in lean conditions.
The only exception is if your soil is truly deficient due to construction or topsoil removal. A soil test will tell you if that is the case. In most Fort Collins yards, the native soil has plenty of nutrients — they are just locked up in mineral form that native plants know how to access.
When to Worry (and When Not To)
Some things that look alarming in the first year are actually normal. Yellowing lower leaves on transplants in the first few weeks is just transplant stress — the plant is shedding old foliage it cannot support while its roots establish. Plants that look wilted in the afternoon but perk up by morning are just managing heat — they are closing their stomata to conserve water, which is exactly what they should do. Grasses that do not seem to grow all summer are investing in roots. They will surprise you next year.
Things that should concern you: plants with soft, mushy stems at the base (crown rot — usually from overwatering or mulch piled against stems), plants that have been wilted for multiple consecutive days despite adequate watering (root damage or disease), and plants being completely defoliated by insects. Native plants can handle moderate insect feeding, but severe defoliation in the first year can be fatal because the plant does not have the reserves to recover.
The Payoff
I will not sugarcoat it: the first year of a native garden requires attention, patience, and a tolerance for imperfection. But the payoff is extraordinary. By year two, your plants will double or triple in size. By year three, you will have a lush, full garden that requires almost no watering, minimal weeding, and zero fertilizer. You will have butterflies, bees, and birds visiting daily. You will have a landscape that looks beautiful in every season — including winter, when the seed heads and dried grasses catch frost and snow.
Trust the process. Your garden is doing its most important work in that first year, even if you cannot see it. Every root that reaches deeper into the soil is building the foundation for a garden that will outlast you.
