Problem on new leaf of my Wallichia

[Phoenikakias]

New leaf looks like bleached. This particular plant has never faced in the past similar problem. What do you think are the causes, luck of nitrogen or a kind og shock because roots found a different soil layer as they penetrate deeper or another cause?

Bleached look could be --- lack of proper nutrition? Apply a palm-specific fertilizer with correct levels of micro-nutrients for palms. (That one seems most likely.) Too much direct sun after a lengthy time in shade? Spider mite infestation? Close observation is needed to determine the cause. If it is a spider-mite infestation, the frond will soon look dry and brittle -- this kills fast. You must act quickly to remove the spider mites and prevent future re-infestation, most often using a systemic.

Picture, sir. Makes a huge difference.

Awfully sorry, I could not upload a picture earlier...

Kim, it has been in this position for decade. Never faced before a mite infestation. The previous leaf is very green and healthy. I feel its stem more fixed in the ground, so roots must have petrated deeper, but problem is that my soil is not homogenous, moreover it took place no basic preparation of soil during the construction of the house and is very probable that also rests of building materials are burried in .

So still no comment after I uploaded a picture as urged to

Hmm, when I had such change of colours on my potted palms, the reason was lack of some Mg, Mn, or Fe. Or if the drainage was bad it was a problem of nitrite instead of nitrate … But in your case? Too hot, too much sun, or …? I don’t know. So I didn’t say anything. Maybe, there is something in your soil as you guessed …

Thanks Pal! What about when colour on this leaf would become gradually normal?! I had a couple of such instances in the past on other palms...

[Kostas]

I usually see that when fertilizer or water is missing and when a plant has had too much dog pee in its root area with not enough water to wash it away

[Phoenikakias]

Ohhh, do you suspect that Mr Brando "lifts his leg" near my palm all to frequently?

[richnorm]

Maybe an oxygen deficiency in the roots? Could have outgrown that spot... But equally might just be a variation in new leaf colour that will come right. I would wait and see.

I'd add some well balanced palm fertilizer w/ micronutrients and some extra iron. That always solves this problem for me.

[Kostas]

With such an established palm and such a dry place, I wouldn't think it's a root problem, but might be worth considering if you have been watering more than other years.

A banana mat and a palm did something similar with too much dog pee and they got over it as soon as I increased watering and told my dog to keep some distance from them.

A fertilizer with micronutrients is always a good idea as well
