My Moss poles are made of 16 gauge wire meaning that as your plant grows to be huge the moss pole will be able to support its weight. The inside of the moss pole is made of long strand New Zealand sphagnum moss that is much better quality than most any other moss pole and is much better for root health. I have a special additive in the moss to aid in strong root growth and the moss is wrapped in a breathable mesh that both prevents the moss from rapidly drying out and prevents the moss from falling out over time. Finally, the pole has sustainably sourced bamboo stakes to provide a strong anchoring in the planting material without the fear of rot like most wooden poles. Handmade in the USA. If you want to order more than 5 please DM or email me and I will give you a bundle discount. Also, please allow 2-3 days for processing then 3-5 days for shipping.
