Named after Adrian Hardy Haworth (1768-1833) an Englishman who was an authority on succulents, butterflies and moths. Haworthia Margaritifera is a succulent that has dark green leaves, thickly spotted with pearly white warts.
Water moderately while in active growth, enough to make potting mixture moist throughout but allowing the top half inch to dry out between waterings. Never let the mixture become completely dry even during rest period.
Not necessary to feed Haworthias.
Use a potting mixture of 1 part coarse sand or perlite to 2 parts of standard soil-based mixture. Since they are shallow rooted plants, half pots are best suited for Haworthias. Always leave 2 inch space between the edge of the cluster and the rim of the pot to allow for new growth.
Remove offsets in Summer. Pot up immediately any offset with roots already attached and treat it as a mature plant. Allow offset without roots to dry for 3 days.
Never place Haworthias in direct sunlight, if exposed to Summer sun, the leaves will shrivel. Normal room temperatures are satisfactory at all times. They have a rest period from mid Winter to late Spring.
Watering is necessary when transplanting, but be careful not to over water.
