Cultivation Notes :
N.sarniensis are simple and undemanding to grow: they thrive in a poor quality, gritty soil and are quite happy in small pots. The bulbs become active in August and start to put out roots. From September on they need watering regularly, letting them dry off while flowering. Then, as the leaves grow, water regularly letting the pots get dry or just damp, and liquifeed using a fertiliser without nitrogen compounds a couple of times throughout the growing season which ends in April. Then put away and dry completely until August ……
We use a mixture that is 5 parts John Innes no 3, 1 part course grit & 1 part bulb fibre. We use 1 litre tall black plastic pots for large bulbs. Split whenever there are too many bulbs in the pot.
They are happy in a temperature band of 4 - 14 degrees C in the winter but cannot tolerate frost which rots the bulbs. During this growth phase they like lots of light and air. Repot every three or four years or top dress yearly.
There will be a good stock of unnamed seedlings for sale.
