Bulbs with very specific growing requirements
In our experience the following bulbs do require extra care.
Boophone disticha – all forms of this magnificent bulb will rot if overwatered or planted in soil that retains even a little water. We have found that the transvaal form thrives if planted out into a rockery or veld garden (wild garden/meadow) when the bulb is still small ie about 2-3cm wide and left undisturbed and it only receives rain water. They do make beautiful container subjects but very special care needs to be taken with them and the pot or container should not be placed in full sun in a very hot area bearing in mind that in nature, tallish wild grasses afford them protection from the heat and their roots do not overheat as is the case in a pot on a hot patio.
Galtonias – best planted in rockeries, embankments or elevated beds and left very much to their own devices.
Ornithogalum thyrsoides – besides the rats that love them, they should also be planted out in their natural winter rainfall region and just left. They rot very easily in pots.
Veltheimias – they prefer dry shade beds and even during active growth, they should only receive rainwater with an occasional watering if it is exceptionally hot. Shade bulbs can of course also tolerate long periods of drought better than sun-loving bulbs and yellow veltheimias are even more fond of dry beds.
Lachenalias – take care when you start watering them and how much you water them once they start sprouting. Best to water frugally until they are in full active growth in late autumn and once they are in full leaf, only water once every 12 days or so.
Haemanthus coccineus – they do not like to be transplanted from mid-summer through to mid-spring. They tend to rot if disturbed at any time other than late spring or early summer when they are dormant.
Cyrtanthus obliquus – extremely well drained soil and never overwater.
