- Flowers: Marigolds and nasturtiums can beautify your garden while attracting beneficial pollinators.
Companion Planting Strategies
Using companion planting can enhance growth, repel pests, and maximize space. For instance, pairing your tomatoes with basil or marigolds can encourage robust growth.
Maintaining Your Elevated Garden Bed
Proper care and maintenance are essential for the longevity of your elevated garden bed. Here are some key maintenance strategies:
Regular Soil Amendments
Each growing season, assess your soil and add compost or organic fertilizers as necessary. This practice helps replenish nutrients and maintains soil fertility.
Pest Control
Monitor for pests regularly and take action immediately to prevent infestations. Integrated Pest Management (IPM) strategies can significantly reduce pest issues while keeping your garden eco-friendly.
Seasonal Preparations
At the end of the growing season, clean out any dead or diseased plant material. This practice prevents disease transmission to future crops.
The Final Touch: Decorative Elements for Your Elevated Garden Bed
Lastly, consider adding decorative touches to your elevated garden bed to enhance its aesthetic appeal.
Decorative Edging
Using stones, wooden borders, or metal edging can define the space and add a polished look.
