    Hello,

    I'm sad to say that my first post to this wonderful forum is one that's reporting a very poorly plant in my garden.

     

    I bought some small Choisya ternata (Mexican Orange) to hopefully grow into an informal screen/border, but as you can see from the picture below, they're not very happy plants at all. The new growth is dissapointing in vigour, and has now gone pale yellow with brown spots. The older foliage below is still quite healthy looking, so I've dug one out of the ground and placed in a pot filled with a healthy mix of multi-purpose compost, sand (2:1 ratio) and a bit of fish blood & bone fertilizer.

     

    The ground where they were placed is quite heavy clay, but I thought I'd dug in enough compost well in advance. What makes me think I've not done such a good job is that the roots are still quite compact. I've gently teased them out for the re-potting.

     

    The soild PH is on the slightly acidic side of neutral. It gets full sun all day, and is low with a fence that shield much of any wind. I thought that would be perfect for most plants to be honest... my only thoughts are that the sub-soil being so clay-ey may be causing draining problems.

     

    With all that info, and looking at the picture below, I'm just looking for general advice really - or if anybody recognises what's wrong? Does it sound like I'm doing the right thing? Once revived, would you replant, albeit after improving the soil condition again?

     

    Thanks in anticipation for any help anybody may be able to offer.
    Best,

    Stella-ta (as in mine's a Stella, Ta!) Big Smile

     That looks like frost damage. The plants are quite hardy, but if you bought it from a nice warm and sheltered garden centre and planted it straight into the garden, it won't have had a chance to acclimatise.

    I suggest you cut off the worst leaves and dead stem tips to tidy it up. Hopefully the older growth is OK and only the soft new growth has been killed. As you've potted it up, leave it in the pot i(n a sheltered place if possible) until it's making healthy new growth.

    Whether you think you can do a thing, or think you cannot, you are right.

    Hi Phot's,

    Thanks for the reply.
    I didn't mention that they were planted last summer, but the damage didn't appear until around Xmas, so frost damage could still be a culprit I guess?
    Yes, I think I'll give this one a right good trimming, and see how it goes. The others are still in the ground and are of very similar appearance.

    Cheers,

    Stella-ta

    It could still be frost. Maybe planting in the summer encouraged soft new growth that didn't have time to toughen up before the first frosts? If so, they'll probably be OK once they've settled in.

    It's not unusual to have a small amount of frost damage on these plants even when they're established, but it's usually not serious and can simply be cut away. 

    Whether you think you can do a thing, or think you cannot, you are right.

    Stella, how is your Choisya now? Did it recover? I have two and they are now 3 years old and look exactly as yours did in the photo. 'It' says they will tolerate partial shade but prefer full sun. Full sun I cannot provide. Does anyone know whether they will thrive in a container for a few years?

    I have had mine in a container for about 18months and it seemed okay until this spring when the leaves looked badly frost damaged at the top, so I cut them back and I had it in full sun but wondered if it needed more shade and shelter? Perhaps it's just been particularly cold and windy this year - at the moment I'm in two minds as to whether to keep it in its pot or put it into the garden.

    I replied earlier to your message about the Choisya - glad to say mine has now recovered and I hope yours has too!
