Hi there..

a) I brought a Buddleja Black Knight a few months ago and it started growing really well. But all of a sudden the leaves are turning yellow and brown mainly along central part of leaves. Any idea why? I've kept it watered really well. See photo.

b) My hydrangea petiolaris doesn't look too great. The leaves are curling and browning at tips. Again any ideas why? Ive watered it really well. See photo.

Anyway many thanks for your advice.

    Both plants seem to be producing new shoots which look healthy. It could be a combination of things - the move, the watering regime - too much can be as bad as too little, the weather conditions...

    The hydrangea is in the ground so I would think the leaf damage has been caused by either the wind or the scorching of the sun, otherwise I think it looks fine.

    The buddleja has flowered and may be running out of steam. The new growth looks fine and the old growth will die back. It is more likely to be affected by watering and it likes to be on the dry side...probably could do with a bigger pot and a good feed next year if you are not planting it in the ground.

    yes I have given them a good watering. Its hard to tell when to stop. I usually stop when the water drainage slows down and the compost begins to get very slightly water logged. is that the right way to do it.? the hydrangea is

    Hydrangea anomala subsp. petiolaris

    thanks for your help.

    Your buddleia is in Autumn mode and you will find leaves falling off large established plants at this time of year. The plant would be much happier in the ground.

    It's always better to underwater than overwater cstonenw5 as most plants can survive an occasional lack of watering but many will be killed by overwatering.  My "rule of thumb" is to stick my finger in the compost;  If it dry an inch down then water otherwise leave alone. image

    A trowel in the hand is worth a thousand lost under a bush.

    Great many thanks for all your kind words of advice. I think I'll plant the buddleja in the ground.
