December in Houston we have relatively mild winters but occasional freezes can occur. So, it is essential to be prepared and to protect cold sensitive plants from frost damage.

• Lawns: Dormant lawns require minimum care. Mowing St. Augustine to a height of ~3” and Bermuda grass back to ~1-2”. Cleanup debris and remove any remaining dead leaves and fallen branches from the lawn areas. This helps prevent diseases and pests from overwintering. If you planted rye grass it will require mowing.
• Bulbs: Mulch bulb beds for winter protection. Ensure proper drainage.
• Annuals: Protect cool-season annuals from frost. Minimize watering.
• Perennials: Continue cleaning up dead foliage.
• Tropical Plants: Provide frost protection in anticipation of a freeze.
• Roses/Shrubs/Trees/Fruit Trees: Leave dormant. 
• Palms: Reduce watering significantly. Prepare for potential frost (for some palms). Monitor for cold damage.
• Fertilizer: Avoid fertilizing.
• Weed Control: Hand-pull weeds during warm spells. Continue to replenish the mulch as this suppresses weeds. Apply pre-emergent herbicides, as needed.
• Pests: Minor issues.
• Diseases: Fungal diseases (due to damp conditions),…
• Watering: Water only during extended dry periods.
• Suggestions for your Landscaping Crew: Ensure that irrigation systems are properly drained and protected from freezing. Continue adding compost to garden beds to improve soil structure and fertility. This reduces the need for fertilizers in the spring. Ensure a thick layer of mulch around plants as this reduce weeds and helps to retain moisture and insulates the plant’s roots and reduces the risk of frost damage. Monitor weather forecasts for potential frost. Be prepared to cover tender plants with frost cloths or other protective measures.
• Garden Cost Management: Closely monitor weather forecasts for freezing temperatures. Plan for winter protection of vulnerable plants. Ensure frost cloths and other protective coverings are readily available to cover tender (tropical) plants. Use this time to plan for spring planting and landscaping projects. This can help to avoid impulse purchases and ensure that the garden is prepared for the next growing season.
