Can anyone tell me why my recently bought Eucalyptus tree, has some pinky leaves on it? It is growing well but at the the lower part of the tree there are branches with the pinky leaves? Am I doing something wrong?

The young growth you mean or the old leaves dropping out which is happening on many at this time of year. They often have different coloured foliage at the start and when they die before dropping off the tree. Put a pic up and we can confirm.

Thank you for the response.. Not sure if it is the old leaves. Just wasn't sure if they did change colour?! It doesn't look as if it is dying, not sure if I should cut them off or not?!

Slc,

all trees, including evergreens, shed their old leaves, and in Eucalyptus they very often turn various shades of red before falling off the tree - they do this for the same reason that trees turn to shades of yellow and red in autumn, the plants withdraw the useful (green) chlorophyll from the leaves leaving the underlying leaf colour behind. If it is the older, larger leaves that are turning pink or red then this will what is happening.

The plants can also shed leaves as a response to stress, and if you have lots of pink/red leaves then there may be an underlying problem, but if it's only a relatively small percentage of the overall number on the tree then it will just be part of the natural process of renewal.

If the pink leaves are the smaller, newly formed ones at the tips of the growth shoots/branches then this would also suggest a cultivation problem.

I am guessing from what you have said Ilex and how it looks, I haven't need to worry. Could you just confirm that I do not need to do anything, ie no need to cut etc..?

Hi Slc,

if it's the old leaves being affected then no, there's no need to cut anything out.

One other thing that occurs to me.... Eucaylptus are very strongly drawn towards the strongest/brightest light, so if yours happens to be in a shadier area, or is crowded lower down, then the plant may be aborting the leaves/branches that aren't proving to be very productive in terms of photosynthesis and energy gathering.

Thank you! I will leave it for the time being and see what happens.

I have 5 Eucalyptus trees that I have started from seeds. They range between 3' and 7' tall. They were all started this year. Because I live in zone 5 (USA), it gets very cold here in winter. I have them in large pots. Since these trees are large, in large pots, and I have several, they need to be kept in a large area. I put them in the garage (attached garage to the house. Near an inside wall. I have put grow lights on each of them that are about 12" above the plant for light and heat. I know they have probably been stressed going from full warm sunlight to a dark garage with grow lights, but the leaves are turning red and dropping off. I have been keeping them watered well (excess water is leaking out bottom after watering), but they still appear to be drying out). I have the grow lights on a timer for 6 hours a day.

Anyone have any suggestions?
