Yellow disease?

[nick]

Hi, I started to replant our garden last year, and some small seedlings are showing yellow leaves.

e.g. the "beccariophoenix alfredii" as you can see in comparison to the "trachycarpus princeps".

For every new planting, I changed the lime soil and prepared it with a mixture of sand and more acid potting soil.

The plants are irrigated regularly.

I'm looking forward to your replies where the problem might be and what can be done.

Nick,

I’m no expert, but I bet its nutrient deficiency. I know that the Beccariophoenixes tend to need lots of Iron and can turn yellow when there not getting enough. When you planted them did you use a slow release fertilizer in the hole like nutricote?

Tomw,

thx. that might be possible, I didn't use slow release fertilizer. I was thinking about plantig a coconutpalm or a B. alfredii and I decided for the alfreddi because of its resistace against yellow leaves. I put some iron regularly around the plant, but obviously it was not enough.

Nick,

I always add a slow release Nurticote or equivalent in every hole that I put a palm in, and I find that it helps. Is it absolutely necessary to put a slow release fertilizer in every hole? No, but it does help! Once in the ground and established I start regiment of fertilizing with a good palm specific fertilizer with all of the minors, even with that sometimes I have to add iron to my Beccariophoenix alfredii. I have friends that are in the business that will spray plant with liquid iron mixture to help green yellow looking palms; this may also be worth a try. Good luck…

Nick, doesnt seem to be Yellowing disease looks like Nutrient def. How long has it been in the ground and how much shade did it recieve prior to being planted?

felixcb,

It is in the ground since spring last year without any fertilizer. I avoid using fertilizer for young plants to stimulate the root growth. Now I feed it with some iron and fertilizer. Let's pray for soon recovery.
