Cordyline going yellow

I have a Cordyline about 3 ft tall in a large pot . This year it started getting yellow bands down the leaves and small brown spots . Had not changed anything to its environment.
So I tried repotting with a Verve season long multipurpose compost. But still same , no improvement . Any thoughts please?

 

Hello Ashley 1234

I grow quite a few cordylines....well, living in Cornwall they are everywhere!......but I think the “secret” is not to water too much. I rarely water mine.

I would use a John innes compost with added perlite or grit......prob 20% or so.

Good free draining compost, full sun and little watering is my regime here.

Remember cordylines shed their older foliage and this is quite normal

 

Hi Verdun , do you ever feed them ?

 

No, never feed them Ashley 1234.
You repotted so there will be feed in the new compost anyway.
It is a plant best left without too much fussing over in my experience.
Mpc are not ideal for long term planting though

 

I dont think they like being pot grown.
They very quickly use up nutrient and produce a mass of roots.

The plain green ones are real hungry and grow far to fast IMO for pot growing.

I've seen the yellow spotting on mine quite often, they usually throw the problem off if grown in the ground but I think in pots its more of a problem.
Still not worked out if it might be some kind of virus.

Those damaged leaves will not recover, you need new clean growth to get it looking good again.

 

I have grown cordylines in pots for several years .......right now a couple have been in pots for 6 years plus ......but I agree with Pete that they really are meant for the open ground. However, for a few years they make excellent focal point plants

Mine were “spares” that were waiting for permanent places and ended up being potted on a few times into large containers. As I said, mine are rarely watered and never fed and they look pretty good I think.

Old leaves regularly lose health and die so best to pull them off. Cordylines want to make tall trees thus dropping lower leaves is all part and parcel of the plant.

 

Ok , thank you all for this advice . I have only a patio garden so no space to plant it into ground were it sounds like it would like to be ! Ill just leave it alone and remove the yellow leaves .

 

No, dont take all the leaves off, wait for them to die off naturally.
The shock would be too great and it would look even worse that the yellow leaves.

 

Could be waterlogging or lack of food as already mentioned. I have a multi branching youngish one in a pot that went yellowish end of last year. Fed it with some good feed in water and the new leaves ate comining up dark green again. So for me it was needinga better quality of feed.

Mines ina pot because bad weather will kill it .

 

Ok , I leave them to drop naturally and just talk to it !
