Orchid Care

Dendrobium cuthbertsonii

Light: Bright, filtered light (1000-1500 foot candles) with good air circulation. Leaves should have a red tinge.

Temperature: 70-80F during the day, 45-55F during the night.

Water: Roots should be damp at all times. Pure water with very low salt is essential.

Media: We recommend shallow pots with New Zealand long-fiber sphagnum moss or fine fir bark. These plants can also be mounted on cork or redwood slabs.

Fertilization: Use a 20-20-20 fertilizer at half-strength every 2 weeks. Never fertilize when roots are dry.

Repotting: Repot annually taking care not to disturb the roots too much.

Pruning: Take care to remove old flowers and leaves during the winter. If a plant has already been blooming for more than 8 months, it is advisable to remove all flowers in the winter to give the plant a rest.

 

Dendrobium kingianum

Light: Very bright light (2000-3000 foot candles). Leaves should be bright green or have a red tinge.

Temperature: 70-85F during the day, 45-55F during the night is optimal. However, these plants can easily tolerate highs of over 100F and lows down to freezing

Water: D. kingianum requires 2 watering cycles to produce healthy crops of flowers. The soil should be constantly damp from March through October. The soil should then be completely dry between November and February. You can resume watering if flower spikes appear earlier than that.

Media: We recommend shallow pots with New Zealand long-fiber sphagnum moss or fine fir bark. We find that the plants grow best when crowded in the pot.

Fertilization: Use a 20-20-20 fertilizer every 2 weeks between March and October. Never fertilize during the dry season.

Repotting: Repot every 2-3 years.

Pruning: Healthy plants will produce numerous aerial keikis every year. These can safely be removed and replanted once they produce their own roots. Dead leaves and bloomed-out spikes should be removed throughout the year.
