Embrace the Benefits of Autumn Planting in Colorado

When gardening in a challenging climate like Colorado’s, the timing of planting can impact the success of our gardens. While spring is often hailed as the prime season for gardening, and summer might seem tempting, there’s a quieter, less celebrated time that offers significant advantages: early autumn. Planting trees, shrubs, and perennials in the fall can lead to healthier, more resilient plants, and a garden that’s ready to thrive come spring. Here’s why autumn should be your go-to season for planting.

Cooler Temperatures = Happier Plants
Colorado’s summers can be scorching, with temperatures frequently reaching highs that stress plants—especially newly planted ones. In contrast, early autumn brings cooler days and nights, which are much gentler on young roots. This milder weather reduces the risk of transplant shock, allowing plants to establish themselves more comfortably. With the intense heat of summer behind us, your new trees, shrubs, and perennials can focus on root development without the added burden of extreme temperatures.

Extended Root Growth Period
One of the most significant advantages of fall planting is the extended period for root growth. In the fall, soil temperatures remain warm enough to encourage root development even as air temperatures drop. This allows plants to develop strong, deep roots before winter sets in. By the time spring arrives, your plants are already well-established and better equipped to handle the growing season’s demands. In contrast, plants set in the ground during summer may struggle to establish roots while also trying to maintain top growth.

Reduced Watering Needs
In Colorado, water conservation is always top of mind, and fall planting offers a water-wise solution. Cooler temperatures mean less evaporation and reduced water stress for your plants. Additionally, autumn rains can help provide consistent moisture, reducing the need for supplemental watering. Newly planted trees, shrubs, and perennials will still need regular watering to get established, but the amount required is typically much less than what’s needed during the hot, dry summer months.

Fewer Pests and Diseases
Summer gardens are often plagued by pests and diseases, which can make establishing new plants a challenge. However, many of these issues begin to wane as the weather cools in autumn. This reduction in pest and disease pressure means your new plants are less likely to face immediate threats, allowing them to settle in and grow without the need for constant vigilance or treatment. It’s a natural way to give your plants a healthier start.

Enjoy Better Selection at Nurseries
While spring and summer might be the busiest time at nurseries, autumn often brings a more curated selection of hardy plants that are well-suited to Colorado’s climate. Many nurseries, like ours, offer sales or discounts as they clear out inventory before winter, so you might find high-quality trees, shrubs, and perennials at a great price. Plus, with fewer customers around, you’ll have more time to browse and get advice from knowledgeable staff without feeling rushed.

Get a Head Start on Spring
By planting in the fall, you’re essentially giving your garden a head start on the next growing season. Come spring, when everyone else is just starting to dig, your fall-planted trees, shrubs, and perennials will already be settled, ready to burst into growth and bloom. This can lead to earlier flowering, stronger plants, and a garden that looks more mature and vibrant from the get-go.

If you’re looking to create a resilient, thriving garden in Colorado, consider making early autumn your prime planting season. The cooler temperatures, extended root growth period, reduced watering needs, fewer pests, and the chance to get a head start on spring all make fall an excellent time to invest in your garden’s future. So, as summer winds down, don’t pack away your gardening tools just yet—embrace the benefits of autumn planting, and watch your garden flourish.

Growing Blueberries: A Comprehensive Guide to Blueberry Care & Culture

Blueberry bushes are an excellent addition to both edible and ornamental landscapes. They not only produce delicious, nutritious fruit but also enhance the garden’s aesthetic with their glossy, deep green leaves in summer and vibrant scarlet foliage in autumn. Here’s how to successfully cultivate blueberries, particularly in regions like the Rocky Mountain West, where soil conditions may pose a challenge.

Essential Growing Conditions

To thrive, blueberries require well-drained, acidic soil (pH 4.5 – 5.5) rich in organic matter. They should be planted in part shade/shade locations and protected from harsh winter winds. Given that naturally acidic soil is rare in the Rocky Mountain region, consider the following methods to create suitable conditions:

  1. Soil Replacement: Remove existing soil from the planting area to a depth of two feet and replace it with a mix of 50% good commercial topsoil and 50% horticultural sphagnum peat moss. Adding extra compost is also beneficial.
  2. Container Planting: Use half a whiskey barrel or a large 20″ plastic pot with additional drainage holes. Fill with the soil mix mentioned above and sink the container into the ground.
  3. Raised Beds: Build a raised bed (3-4 feet wide and 8-12 inches high) using the same specialized soil mix.

Regularly test the soil’s pH using test kits available from Echter’s or other local garden centers.

Plant Care Tips

  • Mulching: Apply a layer of bark chips to conserve moisture, cool the roots, and suppress weeds.
  • Watering: Maintain continuous but moderate moisture throughout the growing season. Avoid over-watering by checking the soil’s top inch for moisture before watering.
  • Fertilization: Annually amend the soil with compost and regularly acidify with products like Ferti-lome Evergreen Food or Miracid. Start fertilizing in May, just before bloom, and continue as directed on the fertilizer label.
  • Pest and Disease Control: Insect problems are rare but can be managed with Malathion if necessary. To prevent fungal issues, water in the early morning and prune correctly.

Bird Control

Birds such as robins, finches, and starlings enjoy blueberries just as much as we do. To protect your crop, cover shrubs with Ross Garden Netting as berries begin to ripen, following the manufacturer’s instructions.

Harvest and Storage

Blueberries are harvested from July through September. Store them in a refrigerator at 32-35°F to keep them fresh for 10-14 days. Fresh blueberries freeze well and maintain their taste, texture, and appearance for up to two years when stored at 0°F. Always freeze blueberries unwashed to preserve their natural protective coating. They can also be canned or processed into syrup.

Winter Protection

For best results, protect blueberry bushes during winter:

  • Apply 4-5 inches of bark mulch around the base in late November after the ground freezes. Remove the mulch in April.
  • Water during extended dry periods or when there’s no snow cover.
  • Stop fertilizing by the end of July to allow plants to harden off before winter.

Pruning Guide

Proper pruning is essential for healthy blueberry plants and optimal fruit production:

  • Establishment Years (First Two Years): Remove winter-killed and diseased wood. Prevent fruit setting to aid establishment by rubbing out flower buds in early spring.
  • First Pruning Year: Prune in early spring after the bush has been planted for two seasons. Remove diseased or dead wood and any crossing canes. Keep two or three healthy canes.
  • Second Through Fifth Years: Continue the same process each year, maintaining a goal of 12 healthy canes of different ages by the fifth year.
  • Maintenance Pruning (After Fifth Year): Maintain the bush at 12-15 canes, pruning out the oldest canes annually and leaving two or three new ones.

Pruning, along with proper soil pH, drip irrigation, and mulching, significantly impacts berry size and quality. Annual pruning ensures consistent, high-quality fruit production.

In summary, with the right care and attention, blueberry bushes can be a fruitful and beautiful part of your garden. By following these guidelines, you can enjoy bountiful harvests of delicious, nutritious blueberries year after year.
