Our playground planting beds make a great addition to a Outdoor Classroom nature center planting area. We recommend going with a 2′ – 3′ high planting bed to help children be able to enjoy sensory stimulation, nature learning and team work while standing. This allows them to stay cleaner while enjoying their playground nature planting experience at ‘eye level’ . These playground nature planters are made from composite materials so they are very durabiliity and will not warp or deteriorate like wood. They make a great addition to an Outdoor Classroom nature center or a playground messy materials area for nature learning.
