2.4 Rooting media and greenhouse soil For information about substrate mixtures and greenhouse border soil, please refer to the Section on tulips (Planting soil and Soil requirements). Unlike tulips, narcissi are especially susceptible to drying out, so it is not advisable to mix too much sand into the rooting medium. Sand does not retain moisture well, which means the soil and crop may dry out too quickly.
