I grow bulbs in both clay and plastic pots, Including about ten Nerine species. (One Nerine I don't have is N sarniensis). Plastic pots don't dry out so quickly and need a more open mix to allow air into the compost. Clay pots are more forgiving of over watering but need to be plunged to give stable moisture and air levels in the compost. Plunging plastic pots also stabilises the temperature in the pots and the plunge acts as a capilliary mat to stabilise moisture in plastic too. Clay pots benefit from a more moisture retentive compost. With small pots I too have found that a lot of south African bulbs do better in plastic, but I believe this is due to not having a suitable plunge arranged for them in clay pots. Did you modify the compost or the way the pots were managed Nick?
