Q.I Just Bought Two Croton Plants That Were Thick With Leaves. They Are In Very Small Pots.
Attached is a pic of the plants showing a pile of leaves. Is it unusual to lose that many leaves because of being in a new location?

Location change is the first thing one looks at when crotons drop foliage. They are very sensitive to change in environment. They should regrow in 3 to 4 weeks.
