Design Tips for Drought-Tolerant Gardens
How often should I water drought-tolerant shrubs in Colorado?
+Once established, most drought-tolerant shrubs require watering only every 2–3 weeks during the growing season. Adjust based on rainfall and soil conditions.
Can I plant these shrubs in clay soil?
+Most drought-tolerant shrubs prefer well-drained soil. Amend clay soil with compost or sand to improve drainage before planting.
Are these shrubs deer-resistant?
+Many, like Apache Plume and Winterfat, are deer-resistant, but no plant is completely deer-proof. Use fencing or repellents for added protection.
What’s the best time to plant drought-tolerant shrubs in Colorado?
+Early spring or fall is ideal, as cooler temperatures reduce transplant shock and allow roots to establish before extreme heat or cold.
By incorporating these drought-tolerant shrubs into your Colorado garden, you’ll create a sustainable, low-maintenance landscape that thrives in the state’s unique climate. Not only will you conserve water, but you’ll also enjoy a vibrant, resilient garden year-round.
