Ceanothus odd green leaves
I have a one year old Ceanothus that produces a blue flower that is
planted in totally the wrong place faceing East rather, than as the book says, a southerly aspect.. It's where it gets full exposure and is fully into the wind, and it doesn't like it. It got frost burnt and wind burnt in the winter, and has reacted by producing a mass of plain green leaves instead of the variegated leaves on the rest of the plant. The RHS site said it hates being moved, so I think it's stuck where it is, but can I cut off the plain green leaves without doing any further damage to the bush. There are quite a lot of them including one spur that is totally green. I am in North Cornwall if that should make any difference. Peter -- - The e-mail address obviously doesn't exist.

Yes, it does - it's not an ideal plant for so far west, let alone in an exposed situation. It will probably never do very well. Sorry. Regards, Nick Maclaren. |

I shan't be planting any more. I shall have to see how my new one does, but the previous one (thyrsiflorus, I think) wasn't phased by Cambridge winters, and they were colder then than they are at present. I have half the rainfall, no salt and sandy soil. Incidentally, California has a solely continental climate, despite the misinformation commonly posted. Even San Francisco itself has - and its microclimate is due to the interaction of the ocean with the continental climate. The only places in the USA with a maritime climate are a thin coastal strip of Alaska, the Florida peninsula and Hawaii. Regards, Nick Maclaren. |

It did very well despite once being partially blown over in a gale (I got it as upright as I could and staked it for a couple of years). When I moved, it had been in the ground over a dozen years. It got a bit scruffy below 1 metre, but never reverted or showed any sign of losing variegation. It survived some very cold winters (-10°C) without a mark, despite the variegated form supposedly being less hardy than non-variegated Ceanothus. In another place in the garden, C.thyrsiflorus repens did well until it got smothered by other, higher-growing, plants. It too got very scruffy before it disappeared. I'm now growing Ceanothus arboreus 'Trewithen Blue' in South Hampshire, again on clay. But despite supposedly being a plant which is quite happy in drought conditions, it lives in a very wet area after heavy rain - almost boggy. It seems to be thriving. Mine never seem to last more than a few years. I think there's more to their loss than just salt gales, although they're bad enough, nor is it cold, as we seldom get frosts below -2C. I suspect fungal attack has a significant effect due to the high humidity here, as even ones fairly well protected from the weather seem to progressively lose their foliage until they become unattractive and flower only sparsely. I am certain that is true. I have problems with labiate herbs, especially in wet winters, with their roots rotting. And I have problems with germinating beans (so I do that indoors). And, in the front garden, I have lost a lot of trees and shrubs (but not all). All are definitely fungal in nature, but it is quite likely that they get infected only when damaged in some other way first. I suspect that the need for good drainage in many plants isn't that they WILL die if they don't have it, but that they are more susceptible to soil-born fungal attack. So they will sometimes thrive even when they "shouldn't". Regards, Nick Maclaren. |

We're on a clifftop and regularly subject to severe SW gales with salt; and when we get the occasional cold NE wind it has absolutely no protection from that. Yet it has never "burned".

Now, if we could all remember which ones lived and died, we might be able to identify which are rubust against such things, and which aren't! I suspect that the standard rules are over-simplistic.

Peter Normally, I would always advise cutting out the plain green shoots at source in order to maintain the less vigorous variegated growth since, presumably, that is why it was bought. However, in this case, I would be inclined to let the stronger green growth prevail. Although I like many variegated plants, I've never been able to admire variegated Ceanothus (sorry) but, rather more importantly than my personal opinion, I think the green form may stand up to your weather conditions better. I also suspect that your plant agrees with me, since it produced green leaves to help it cope!;~). I also think it's worth giving it a high potash feed to help harden off the foliage. Certainly don't give it any nitrogenous feed which will encourage soft growth. -- Spider. On high ground in SE London gardening on heavy clay |
