How do you make a large planter box?
Choose a high-quality potting soil for your planter box; don’t use garden soil. Potting soil is sterile, free from weed seeds and diseases and blended with a material such as pumice or perlite to provide good drainage. Fill the planter box to about 1 inch below its rim. The extra 1 inch allows space for watering.
