The Ultimate Guide to Growing Strawberries in Colorado

Understanding Colorado Climate

Most areas suitable for gardening fall in USDA Hardiness Zones 4 through 6. You must select plant varieties that can withstand potential cold snaps. The state's high altitude also influences temperature variability and can affect growing seasons.

Best Strawberries to Grow in Colorado

Day-Neutral vs. June-Bearing Varieties

Day-neutral can produce fruit throughout the growing season. June-bearing produces a single crop per year. Their harvest window is shorter. But june-bearing varieties often yield larger fruit. You can choose them if you want to harvest a significant quantity at once.

Recommended Varieties

Some of the recommended day-neutral varieties include Albion, Seascape, and San Andreas. They have consistent yields, disease resistance and excellent flavor.


June-bearing strawberry varieties are reliable choices for Colorado gardens. For example, Honeoye and Jewel. They offer robust growth and good cold tolerance. They also produce wonderfully sweet berries.

Preparing the Garden Bed

Selecting an Appropriate Location

Strawberries require full sunlight. The area should also shelter from harsh winds. A south-facing slope is often perfect. It provides the necessary sunlight and natural drainage.

Soil Preparation Techniques

Strawberries have shallow root systems. They can suffer from waterlogged conditions. So ensuring proper drainage is essential. Start by testing the soil to determine its composition. Then amend it with organic matter to improve soil structure and fertility. For example, compost or aged manure. You can add peat moss to the heavy clay soil.

When to Plant Strawberries in Colorado?

The best time is in early spring. The soil becomes workable but after the last frost. This period generally falls between late March and early May. The strawberry plants will become well-established when planting during this window.

Proper Spacing and Depth

Space them 18-24 inches apart when planting strawberries in Colorado. This allows for adequate air circulation and preventing fungal diseases. Make sure the crown is above the soil surface when growing strawberries in Colorado in pots. The roots should spread out evenly in the hole. Planting too deep can cause the plants to rot. Planting too shallow may prevent them from establishing properly.

Transplanting or Starting from Seedlings

Incorporating a balanced fertilizer to provide essential nutrients. Select young, healthy plants for transplanting. Gently loosen the roots before planting. If starting from seedlings, you should begin indoors in late winter. Then, transplanting outdoors in spring. Protect young plants from extreme weather with a row cover if necessary.

Care and Maintenance

Watering Requirements

These berries prefer consistent, even watering. Strawberries require 1-1.5 inches of water per week. Using soaker hoses delivers water directly to the roots. Early morning watering is best. Any moisture on the leaves can dry before evening.

Mulching Techniques

Organic mulch can retain soil moisture and suppress weeds. For example, straw or pine needles. Apply a layer of mulch around your plants. Take care not to cover the crowns. Mulching after planting or in late fall also protects the plants from cold.

Fertilization Schedules

Strawberries benefit from regular fertilization. But the key is choosing the right type and timing. You should use an organic fertilizer low in nitrogen. Apply it in the early spring is best.

Protecting Strawberries from Pests and Diseases

Common Pests and Diseases

Spider mites, aphids and strawberry root weevils are common culprits. Additionally, fungal diseases can significantly reduce yield. For example, powdery mildew and verticillium wilt. You should identify these pests and diseases early.

Organic Methods for Pest Control

You can plant certain flowers alongside your strawberries. This can naturally repel attract beneficial insects. Planting marigolds can deter aphids. Native ladybugs can keep the aphid population in check.

Preventative Measures

Make sure proper spacing between plants. This ensures sufficient air circulation and reduces fungal diseases. Rotate your strawberry crop every few years. This can help avoid the buildup of disease in the soil.

Pollination Strategies

Attracting Pollinators

Creating a pollinator-friendly environment. Planting native flowers alongside your strawberries. This can provide pollinators with additional nectar sources.


Maintaining a pesticide-free garden protects these vital creatures from harm. Ensure they continue their critical work in pollinating plants. Water sources can also attract and sustain these beneficial visitors to your garden.

Hand-Pollination Techniques

Hand-pollination is a practical method if pollinator activity is low. You can use a small paintbrush. Gently transfer pollen from one flower to another within your strawberry patch. This meticulous process can significantly increase the likelihood of fruit set.

Harvesting Strawberries

Signs of Ripe Strawberries

Look for berries that are uniformly red, without white or green parts near the stem. These colors herald full ripeness and peak sweetness. The timing is key in Colorado. Strawberries typically ripen from late May through early July. So pay attention to your crop as these months approach.

Proper Harvesting Techniques

Gentle touch to avoid bruising these tender fruits. Use garden shears to cut the stem just above the berry, rather than pulling the fruit directly. This method ensures the berry remains intact. Morning is the best time for harvesting. Because the cool temperatures keep the berries firm.

Troubleshooting Common Issues

Yellowing Leaves

This issue often stems from nutrient deficiencies. For example, nitrogen. Enhancing your soil with a balanced fertilizer. Ensure plant your strawberries in well-draining soil. This prevents waterlogged roots, which can also cause leaves to yellow.

Poor Fruit Production

Strawberry plants require 6-8 hours of direct sunlight. Thinning can also improve air circulation and light exposure. This can significantly boost fruit production.

Reviving Struggling Plants

The first step is to assess their environment. Ensure they're in a location with sufficient sunlight. If pests are an issue, organic deterrents are effective yet gentle on the plant. For example, neem oil or diatomaceous earth.
