recently planted a cabbage tree outdoors (not in a tub) and just
recently the leaves (some at the base and one or two further up
the plant) have started going yellow. Can you please tell me what
the problem might be, i.e., am I not giving it enough water or too
trees often shed leaves and this is just a natural process of leaf
aging and death. However, this is usually from the lowest leaves
only. Leaves going yellow and dying further up the plant could indicate
that there is something wrong.
You don't say how big
your cabbage tree was when you planted it. Larger cabbage trees
produce a long carrot-like rhizome that is used for food and water
storage. If this rhizome was damaged, it could explain the loss
of leaves. Otherwise, the leaf loss could be due to erratic watering,
either too much or too little. Unfortunately, the symptoms are basically
Make sure that the plant
is in well-drained soil. If the soil is too wet, you could cause
the roots to rot-off. Check the soil moisture level by placing a
dry finger in the soil. If soil sticks to your finger or the soil
feels moist, then you do not need to water.
