Yellowing from the bottom up?

[Nooby]

I've got one girl that's about 2 1/2 months old in a pot outside, she's about 3' tall and seems to be going OK but lately I've noticed the leaves are turning yellow from the bottom up and the leaf stems are purplish. Is this an NPK problem? I thought the new potting mix should have been ok for a few months?

 

Cheers

Stem leaves (petioles) purple = stress

general yellowing 'bottom up' = recycling nitrogen

 

Plant is experiencing stress due to growth outstripping nitrogen supply. Feed plant extra nitrogen.

 

Is your potted plant protected from rain? If not, it's likely much of the available nitrogen has been flushed from the pot.

Yeah been getting a bit of rain lately. I've fed her up and chucked her under cover.

 

Thanks.

No worries then, keep her out of the rain.

While we're on the subject what normal food should I be using? Thrive? I want to use stuff I can get at the local nursery.

I'd go with fish emulsion and seaweed extract in preference to thrive... both available at supermarkets.

Cool, so if I water once every 7 days should I feed them at the same time, or every alternate watering?

 

 

Thanks again.

Nooby you joined 2 years ago, surely you've picked up something about growing weed in that time.

[Nooby]

You'd have thought so.

 

Each year seems to bring new issues though.
