Dendrobium orchids can indeed thrive when potted with sphagnum moss. Sphagnum moss is a great option for potting medium because it retains moisture well, providing a humid environment that Dendrobiums appreciate. This type of moss also allows for good aeration, which is important for the health of the orchid roots.
Personally, I have had great success using New Zealand Sphagnum Moss for my Dendrobium orchids. I find that it retains moisture better than other types of moss, and it creates a nice, loose potting mix that allows for good drainage. Dendrobiums have a reputation for being relatively tolerant when it comes to potting media, but sphagnum moss has proven to be an excellent choice for their needs.
Another option that works well for potting Dendrobiums is our Traditional Orchid Bark Mix, specifically the Medium grade. This mix is made from a combination of different types of orchid bark, which provides excellent drainage while still retaining some moisture. The medium-grade bark mix consists of smaller pieces of bark, which is ideal for Dendrobiums as it allows for good root penetration and airflow.
When it comes to repotting Dendrobium orchids, it is generally recommended to do so every 2 to 3 years in the spring. This allows the orchid to have fresh potting medium and gives you the opportunity to inspect the roots for any signs of damage or disease. Repotting in the spring also coincides with the natural growth cycle of Dendrobiums, as they tend to produce new growths and flower spikes during this time.
Dendrobium orchids do indeed like sphagnum moss as a potting medium. It provides the necessary moisture retention and aeration that these orchids prefer. However, the Traditional Orchid Bark Mix, particularly the Medium grade, is also a suitable option for potting Dendrobiums. Ultimately, the choice between sphagnum moss and orchid bark mix may depend on personal preference and the specific needs of your Dendrobium orchid.
