I purchased 4 little Croton plants (about 6 inches tall) about 2 years ago and planted them in what seemed like a big pot for their size (8 inches wide and 5 inches deep). Since then they have grown significantly with the two tallest now up to 2 feet tall.
Are they going to continue to be healthy in this pot together? Or will they need to be separated or put into bigger or deeper pots? And if they do need to be separated and/or re-potted, when would be the best time to do that? I enjoy my beautiful office plant and want to be caring for it properly so it will stay beautiful.
