Weekly Gardening Tips - September 12, 2009

• The average killing frost along the Front Range is usually mid to late September (varies according to your location) and earlier in the mountain areas. A killing frost occurs when the temperature drops to 28 degrees F. As fall approaches, pay close attention to the weather forecast for frost warnings and be prepared to protect your plants.
   
• Aerate your lawn this fall to decrease thatch and help eliminate soil compaction. Compaction decreases the amount of oxygen that is available to the roots.
• Let blooms on plants fade and set seed for next year’s garden. Collect seeds at maturity and place in a cool dry storage area until planting time next spring.
• Journal about successes and failures in your garden and landscape. Evaluate plants for drought resistance, amount of light, sun and water needs. Group plants with similar water requirements together. Install a drip or trickle irrigation system and utilize water-wise gardening techniques. Drought resistant plants are available in many colors, textures, and heights. Plan for times when water is more readily available and be ready for change, challenges and fun gardening.
