If more than eight bulbs and at least two neutaries have formed in older plants, the dendrobia can be divided. For really large orchids, this method also provides for the rejuvenation of blooming plants. Divided at a time when the orchid is repotted anyway.
- Remove the plant from the pot and shake off as much soil as possible
- Carefully pull the roots apart
- Rhizome (connection between the bulbs) with sharp knife
- pay attention to cleanliness (sterile knife, scissors)
- At least 4-5 bulbs must be left per plant
- Replant both (or more) parts separately
- after the division, some dendrobia may experience longer flowering breaks
3. Head cuttingsIn rare cases rooting is observed in some Dendrobium species in the upper third of the plant. By applying moss and spraying frequently, their growth can be increased. If the roots (after a few months) are well formed, the head cuttings are cut off from the mother plant and potted in a separate planter.
overwinterMost dendrobium thank a more or less extensive hibernation with lush flowers in the following year. For most species, lowering the temperature to 15 degrees is sufficient. Some varieties prefer to stand permanently at about 10 degrees. The cooler the orchid is, the less water it needs. However, the overwintering place should definitely be bright, as most of the grape orchids keep their leaves during this time.
- fertilize with warm overwinter once a month
- in cool wintering the plant needs no fertilizer
- pour behavior (once a month)
- protect against drafts
- Temperatures must not be less than 10-12 degrees!
- Exception: Dendrobium nobile (over 5 degrees)
Diseases and pestsWith good location and care conditions, orchids such as dendrobia rarely get sick. However, when the humidity in heating mode drops, sometimes sucking pests such as scale insects occur. Often, a rotten root can be seen when the orchid is too wet. Then it is urgent to remove the old soil and putrid roots and plant the dendrobia in fresh substrate.
ConclusionOrchids of the genus Dendrobium are among the most popular orchid species in our homes. The most diverse hybrids with colorful or bizarre flower forms are available in the trade. Dendrobium do not make very high demands on a hobby gardener and reward a little attention and care (almost) all year round with magnificent flower spikes.
