Looking for some late-summer, early autumn perennial bloomers? Add a colorful chrysanthemum to your flower bed or fall container garden! Fort Collins Nursery offers hundreds of these prolific, hardy and beautifully bushy perennials.
Mums come in a wide variety of colors, from yellow, pink, magenta, red, lavender, and more. Blooms on mums typically last for weeks providing a late-summer boost when other flowers have given out. And did you know that mums’ flowers are edible?
Fort Collins Nursery also offers a great selection of colorful asters, also a hardy late-summer and autumn bloomer. Small, abundant, star-shaped flowers tower on 2-3 foot plants, providing a nice backdrop in perennial beds.
Both mums and asters appreciate full sun, and a good dose of compost when planted. They also prefer to be watered at their base. Watering from above, onto the leaves, can encourage powdery mildew.
Nothing smells as inviting as fresh garlic sautéing in a pan. These tasty bulbs can be added to nearly any style of cuisine, or even roasted and eaten by themselves.
Fall is the time to plant garlic for next year’s harvest! This over-wintering bulb needs at least four to six weeks to establish itself. Plant garlic cloves about 12 inches apart in loose, amended soil with plenty of organic matter. Garlic will do best if planted when soil temperatures are 40°F, but before the ground freezes.
Each garlic clove will produce a bulb in the summer. After the leaves have turned brown, garlic is ready to be harvested. Harvest is easiest with a digging fork to loosen the soil without disturbing or damaging bulbs. Drying garlic, or curing, can help your harvest last for up to a year. The biggest and healthiest cloves can be replanted again in the fall.
Keep soil moist but not too wet, which will rot garlic bulbs. Make sure to keep the beds free of weeds, which competes too much with the bulbs.
Fort Collins Nursery has garlic varieties arriving in September, but they don’t last long! Stop in and get planting!
Lawns will especially benefit from fall fertilization with a healthier root system, which will mean a dense, green lawn in the spring. In Northern Colorado, lawns can be fertilized right up to Thanksgiving (late November). We recommend either Jirdon Winterizer Fertilizer (conventional) or AlphaLawn Turf Winterizer (organic).
Trees and shrubs do best with a complete fertilizer. such as Jirdon Tree & Shrub Fertilizer, after leaves have fallen.
Autumn is also a good time to add chelated iron fertilizers for iron deficiencies, which is indicated by yellow-colored leaves throughout the growing season.
When in doubt, ask one of our knowledgeable staff to help you choose the fertilizers that are right for your landscape.
Even though winter is here and plants are dormant they still need winter watering in our high desert climate.
We recommend thoroughly watering trees, shrubs, lawns and perennial beds at least once a month. Remember to water when temperatures are above 40 degrees, and with enough time for the water to fully soak into the soil.
Added water, along with a thick bed of mulch, will help protect plants throughout the harsh winter months.
Newly planted trees, shrubs and perennials are the most at risk. Try to water these 2-3 times a month. Fall-laid sod will also need extra moisture.
Finally, make sure that you disconnect and drain your hose after watering to avoid freezing pipes and to prolong the life of your garden hose. Please contact us with any questions.
This is the time of year to clean up the garden in anticipation of winter and a carefree spring.
Fallen harvests attract unwanted pests. Raccoons, mice, insects and fungus take advantage of your plants for food and habitat. Clearing out vegetable gardens to reduce chances of attracting pests.
If you want to encourage wildlife, leave seed pods, berries and rose hips on plants. A water source is also appreciated. Also leave ornamental grasses untrimmed until the spring.
If plants have any diseases present, throw them in the trash. Many foliage-based diseases can survive the winter in compost bins. Toss out any weeds, such as dock, vine weed and dandelions. These stubborn weeds spread seed or remain dormant, only to resurface in the spring.
Save fallen leaves to use as mulch or to add to the compost pile. Add the last few rounds of grass clippings to the pile, they’ll help add nitrogen.
To prepare your plants for winter, reduce irrigation, but don’t cut it out entirely. Colorado winters can be dry, so give plants 1-2 soakings per month until spring.
Use tree wrap to prevent sunscald on thin-barked trees after late October. Remove wrap in early spring, when budding occurs.
Hybrid Tea, Grandiflora, and other grafted roses need more winter protection than other varieties. Prune back long canes in November to protect them from snow damage, or wait until mid-April and leave the rose hips for winter interest. Remove debris from the base of the roses, and use a rose collar to hold soil, compost, straw or bark over the rose crown. We carry rose collars, which can be reused year after year. In the spring, the collars can also be used to protect starter tomatoes.
Every Autumn, our garden shop is taken over with a diverse selection of bulbs for Spring color! Tulips, daffodils, iris, crocus and more are available in a rainbow of colors. These bulbs can be planted up until the soil freezes, but shop early for the best selection!
We also offer amaryllis and paper white bulbs that can be forced to bloom in the Winter months. Call or stop by for availability, and chat with one of our knowledgeable staff for how-to tips.
After a long and productive growing season, most garden soils can benefit from amendments before the ground freezes.
Renew organic matter in the vegetable garden and now empty flowerbeds while also clearing the yard of debris. Run a lawn mower over fallen leaves, collect, and spread in beds. Dig and mix leaves into soil to a depth of 6 inches.
Also, add broken-down compost from the bottom of your compost pile, or add bagged compost. Dehydrated cow or sheep manure makes an excellent amendment. All this effort in the autumn and early winter means only having to turn soil and plant in Spring!
Perennials such as mums, asters, hibiscus and ornamental grasses are showing fabulous fall color, shape and texture.
