ProWood Raised Garden Beds

Raised bed gardening is a fun and effective way to grow vegetables and flowers in rural and city environments. Raised garden beds help protect plants from pesky animals and foot traffic while allowing the soil to warm faster in the spring to produce early crops, healthier plants and higher yields with less work. Raised garden beds can also be decorative and will add a touch of charm to your vegetable garden or outdoor living area.

Whether you are building a raised garden bed to grow vegetables, herbs or flowers, ProWood pressure treated lumber is your best bet! Why? It's simple – ProWood pressure treated lumber is attractive, low cost and most of all SAFE for use when planting and consuming vegetables and herbs. 

Laboratory and field studies have verified the effectiveness of micronized copper azole (ProWood's treatment type) in protecting against rot, fungal decay and termites in above-ground and ground-contact use. Naturally decay-resistant wood such as cedar or redwood are also good choices, but are more expensive than pressure-treated lumber, fade quickly and may not last as long.

Advancements in pressure-treated lumber have made ProWood safe for people, pets and the environment. What's more, ProWood's micronized copper formulation used in the treatment process has earned Environmentally Preferred Product status from Scientific Certification Systems. 

This formulation gives the wood a light, fresh appearance compared to formulations of the past. The treatment used in ProWood lumber is GREENGUARD Gold Certified. GREENGUARD considers safety factors to account for sensitive individuals (such as children and the elderly), and ensures that a product is acceptable for use in environments such as schools and health care facilities.
