Enhance your landscape's decor by using a natural-material planter to grow plants. Wooden planter boxes are effective for growing plants on decks and patios, within the landscape or around outdoor entertaining areas. Decide on whether you want to keep the natural look of the wood or paint the wood for an additional decorative element to contribute to a colour scheme. Choose a planter box size based on the type of plants you want to grow, and place the planter in a location that accommodates the plants' growing requirements.
Paint the inside and outside of the wooden planter box with a nontoxic stain that prolongs the life of the wood. Use either a clear stain or one that is darker than the wood. Dip your natural-bristle paintbrush in the stain can and paint both the inside and outside. Allow your wooden planter box to dry on newspaper.
Line the inside of the planter box with plastic. Make drain holes at the bottom of the plastic with a knife. Tape the plastic right up to the top of the planter box but out of sight from viewing.
Hammer rustproof nails into the joints of the planter box to keep the box from falling apart from moisture.
Fill a container that fits into the planter box with potting soil up to 1/2 inch from the top. Check underneath the container to ensure that it has draining holes that are at least 1/2 inch in diameter.
Place a saucer on the bottom of the planter box. Layer 1 inch of gravel at the bottom to assist with drainage. Set the container on the saucer. Make a hole in the potting soil twice the diameter of the plant's root ball and at the same depth as the plant is planted in the container. Place the plant in the hole and pack the soil around the base.
Water your plant by lifting the container out of the planter box and watering the base of the plant. Stop watering when water runs out of the draining holes on the bottom of the planter.
Avoid using treated wood for growing vegetables, because the wood releases toxins that are poisonous.
