Drying weddelliana

Recommended Posts

Hello all, my Syagrus weddelliana is drying up. First, the leaves started to turn light green, then they began drying up. All of this occurred in a three-week time. Of 12 leaves, just three survived, but they are light green partially dried. The youngest of the leaves of them stopped opening its leaflets. There are three inflorescence spears that didn't open. And there's one leaf spear I expect to open. It seems that it stopped drying (the pics were taken one week ago and the situation remain at the moment I write), but the plant is probably too weak.

This occurred after I changed its place. Previously, it was placed in my balcony, but as the summer sun started to reach the plant's former place, I had to move it indoor (with less winds, less light and more heat). I don't know if it felt the change. During the last weeks, temperature has reached 35oC, 40oC. It also had some scales, that I manually removed.

I don't know what may have caused the problem, how to solve it or if the plant is doomed...

It looks like a root problem. I don’t know what happened to your palms during the heat on your balcony, but my Weddells were exposed last summer outdoor to temps from 38°C (day) to 26°C (night) with extremes of 42°C on the balcony without any harm. So I guess the roots of your Weddels might have dried out (too little water) or boiled (to much direct sun on the black plastic pots).

The first thing I would do is cutting off all (completely) dried fronds. And than put the palms onto a half sunny place (with some protection on your balcony). Give it a lot of water but don’t leave any water in the saucer. — In case you think it might be almost hopeless with your palms remove them out of the pots and look if the roots are still whitish to bright brownish yellow or if they are soft and already rotten. And post a photo of the roots here.

I had similar issued with Lyto's, soil looks too wet. They are very susceptible to fungus & quick death. Both my Wedd's did the same. Changed my soil to something very similar to what Pal uses & haven't had a problem yet.

As your Weddell has already a real trunk it may be relatively strong. I would recommend that you should try a mineral rich soil mix which has a very fast drainage like that one I am using for L insigne. But when you remove the old (loamy?) soil be extremely careful not damaging the fine roots.

Here for comparison older photos of my N°1301 (now 170 cm tall) and the youngest N°1308 before they got repotted:

So, how are my roots, Pal? Are they rotten?

I don't think I can find Seramis in Brazil. Can I substitute it with another soil?

It looks like only some thinner roots are rotten. But if the roots are still hard they should be ok. Try to remove most of the loamy (?) soil.

Seramis® is a soft clay granulate, a liitle bit like baked lateritic soil. If you can’t find it try it even with crushed (!) LECA. It is important that you can water your palm without the soil getting soggy.

If you have a hydroponic store close by they may stock something similar in terms with expanded clay pebbles.

I use a mix similar to Pal Meir and it works a treat with all my palms.

Equal parts coco coir for pots, coarse grade perlite, pine bark fines, hydrocorn (expanded clay pebbles)
