I have well established, two year old dipladenia. It stands about eight foot in part shaded conservatory (only heated when frosty). In February it started to have yellowing leaves and a lot have fallen. I have given it a ballanced feed but to no avail. What should I do? re-pot? another type of feed? Any advice most welcome!

carmina - was your conservatory heated all night long when we had that severe weather in february? if not the night time temperatures may have caused the yellowing leaves and leaf drop. it may well recover as the days get warmer and sunlight hours longer. another cause may be too much water in winter.

My Dipladenia is the same age as yours Carmina and during the winter, it lives in a heated greenhouse with plenty of light. When I first bought the plant, the care instructions were very sparse and I couldn't find much info on overwintering them so I emailed the breeder of them - the reply was it needs to be kept at a minimum of 10 degrees C over winter and kept on the dry side and increase the watering once new growth begins to appear. As mini stroni has said, it could be that the plant has had too much water over winter and fluctuating temperatures probably wouldn't have helped it much either. I only give mine the occasional feed during the summer months when it sits outside.

In my vast and sad experience the usual cause of death of indoor plants is over-watering.
Curiously only about one in ten thousand gardeners, even experienced ones, thinks to take the plant out of the pot and look at the roots...I suppose it is bit like IT helpdesks and plugging the computer in - the simple and obvious passes people by in their anxiety that something deep and mysterious is going on.

Sadly I think it might be over-watering plus keeping it a bit cold!! I am not sure what Ph it requires (and I will have to seek advice there), however I will keep it warm and hope it survives... any views on re-potting?
In todays sunlight it looked a little better! (wishful thinking!) It has been a very colourful plant and it would be a pity to lose it!
By way of interest it sits next to a wall mounted pot of "purple bells".. which I was told need the same environment and they are thriving
Many thanks for all your advice!

You don't need to worry about the Ph Carmina, it will be happy in any soil. Mine is planted in a half-barrel in multi purpose compost with perlite mixed in for drainage.When I planted it, a bit broke off which I poked into the compost and it took root very quickly, the two plants will stay in the same container. I'm certainly looking forward to seeing it flower again this year (I have the red one) and I love it's aroma when the sun is really hot.
