Variegation A common cause of variegation is the masking of green pigment by other pigments, such as anthocyanins. This often extends to the whole leaf, causing it to be reddish or purplish. On some plants however, consistent zonal markings occur; such as on some clovers, bromeliads, certain Pelargonium and Oxalis species.

- Brown Patch. Brown patch can be a problem in zoysia grass. Rhizoctonia fungus is often the culprit, caused by overfertilization. Fortunately, it does not kill the grass and zoysia is able to recover as it fills in during the warmer weather. Proper fertilization and watering helps to control this disease.oysia grass tends to produce thatch from dried cuttings and dead material that can cause brown patches on the lawn. This material can get quite thick and tangled and prevent fertilizer and moisture from reaching the soil and roots.
