Wanted to share my follow up video after my first month of using PalmGain, for those of you that were following along!
I have a mature Canary Island Date Palm that needs fertilizer badly. The margins of the fronds are turning yellow prematurely. I finally got the right fertilizer, but I’m not sure how to apply it. The instruction says to apply it to the area under the canopy. But the area under canopy are mostly hedges and grass. What do I suppose to do?
Apply the fertilizer to the hedges and grass and hope that the wrong fertilizer won’t kill them and some will make it to the root zones of the palm??
Alternatively, skip the hedges and the grass, apply only to the Root Initiation Zone (RIZ) of the palm wherever possible, including the dormant aerial roots?
I’m in South California. The fertilizer I initially ordered was Palmgain, but it never arrived. I went to a local store and got Palmtone (organic 4-1-5) and Epsom Salt instead to mimic Palmgain. Since Palmtone is organic, I'm assuming it's ok to apply close to the trunk where the RIZ is.
Any help would be greatly appreciated!
Does anyone know of or recommend mineral supplement WITHOUT any nitrogen?
I have alkaline soil, which I am trying to acidify, but meanwhile I would like to be able to add mineral supplement without the fear of fertilizer burn.
Iron is easy to come by at the local garden store.
Epsom salt is a good source of Magnesium, but how about the other minerals that palms need such as Manganese, Boron, etc.
I recently acquired several different Tillandsias to add to my collection. I've included a few in the photo below. Does anyone know the cold hardiness of the non-native forms and hybrid? I'm thinking they aren't as hardy as our native Spanish moss, but figured I'd check if anyone on here knows. For now, I plan to treat them like I do for my other non/less cold hardy Tillandsia species.

I made a small research on Palmtalk about the potting mix people use and decided that I need to upgrade my growing medium to some decent level.
Most of the time, I was using a "palm substrate" mixed with sand, but it was really hard and heavy - as you can see here:
I have Brahea, Butia and some other subtropical palms sprouting now, so I realized they need some more mineral substrate.
I prepared this mix: LECA (expanded clay) : perlite : pine bark : palm substrate (mostly peat) = 1:1:1:0,5
What do you think about this mix? Anything to improve, add?
My other concern is, how is the best way to fertilize, and when to start? The mix alone doesn't provide much nutrients, on the other hand I am afraid to burn these small seedlings with fertilizer. I have some decent one 19-6-20 + 3 Mg etc.. but it is used in it's liquid form. Can I prevent the damage by diluting the fertilizer to third or maybe a quarter of the recommended dose?
Thanks for help!
