| Cultivation Details | Growing Cyrtanthus can be a tricky business indeed. We have many species and hybrids growing here at Mainly Amaryllids Garden and we are keen to expand this genus in the enthusiast's collection. We also do a little breeding each year, trying to create new and interesting hybrids.
To quote most avid Cyrtanthus collectors, this genus includes some very easy to cultivate species. However, there are many species that are hard, if not difficult, to cultivate. C. spiralis is very sensitive to water in the medium and C. obliquus is known for its resistance to home cultivation. I have them growing on the side of a Tree Fern log and they are doing very well, much to my surprise. This species is in the group of 'very hard to cultivate' Cyrtanthus. Reputedly, they die after 4-5 years growing, not long before flowering. This can be frustrating for many gardeners. Proper study of this genus, corresponding with fellow Cyrtanthus growers and careful observations in mediums used are all good ingredients for the Cyrtanthus collector. Very difficult species like Cyrtanthus spirals need to have a large amount of course gravel into their mediums for excellent drainage.
Most species prefer light shaded areas. C. clavatus, C. ochroluecus, C. mackenii, C. obrienii, C. angustifolius, C. sp. (wide leaves), C. sp. (Eastern Cape), C. sanguineus, C. smithiae, C. epiphyticus, C. obliquus, C. falcatus, C. contractus, C. elatus all do well here in partial shade, morning sun and very good drainage in the medium. Cultivating Cyrtanthus is some thing you need to experiment with in your garden. They are niche dwellers. Buy this I mean that once you find a good spot for them to grow, do not move. Look for similar places in your garden and plant the Cyrtanthus there too. Or, you can try to make an environment for them. Most of the above Cyrtanthus do well in the shade house or fernery. I have found 50% sand mixed with 50% potting mix a good growing medium for the above species. This medium provides plenty of air and constant moisture availability.
C. spiralis, C. helictus, C. herrei and C. montanus are species that have specific needs in their medium requirements. Fill the pot that you are using 1/2 way with broken bricks or large stones. Cover this with a 1-inch stone to seal the large air holes and stop the medium from falling through. Them, using a mix of 3 Parts Orchid bark (5-10mm), 2 Parts sharp sand and 1/4 part leaf mulch (composted), pot on your bulbs as usual. Keep in mind that many species like to be planted with at least 1/2 the bulb showing. If they want to go deeper, they will do this on their own. These 4 species also need more sun light/less shade to do well. Place the pots where there is plenty of airflow.
Feeding is by composted cow manure. I spread a light application of this at the start and during the growing season. This can also be added as a liquid fertilizer, soaking the composted manure in water for a couple of days before use. |
