Answer: Zamioculcas tends to yellow and drop foliage when it is overwatered. It will need less water during the winter than it did in the summer because it is growing less due to the lower light levels. Also make sure that it is not in direct sun; as the days shorten the sun angle changes and this can put a formerly shaded spot into direct sun. Generally speaking it is not a good idea to repot a plant that is not doing well as this adds additional stress.
Lavender requires a bright location with full sun, good air circulation, and perfect drainage. This is a plant that will not survive in soil that is overly wet or if it is overwatered. You might try creating a slightly raised bed for it using a sandy soil with a neutral or slightly alkaline pH. Do not mulch it.
