Best way for greening up yellow palms in the spring?

Nitrogren? Iron? Some particular micronutrient(s)? Some sort of foliar spray so it gets straight into the leaves?

Many of my palms (the fishtails look the worst) could really use some greening up right about now.

I don't know Justin. It seems like nothing works right now. The warmer weather seems to be the only thing that works.

Epsom salts as foliar spray with a little added nitrate should work wonders!

nutrient uptake is almost nonexistent when soil temps are below 60F, so as mattyB says nothing works right now. Part of that is the soil microbes that assist uptake are dormant, the other part is that the plant root system is dormant.

Formerly in Gilbert AZ, zone 9a/9b. Now in Palmetto, Florida Zone 9b/10a??

We get plenty of nutrient uptake here in Norcal with soil temperatures below 60F. All my palms grow actively throughout the Winter, even when surface soil temps drop in the 50's. Some of the highland palms actually put on a ton of growth in the Winter, their metabolism is in full swing right down to the 32F mark. My palms are green, not yellow, but perhaps it has more to do with good drainage and species selection that can handle the cold. I have new spear push on just about everything.

Even my chamberonya is growing actively through the Winter. All the desert types also grow actively in the Winter because there is a ton of water available.

I'm with Matt, Justin.

I've got the same problem. Warm weather is the best cure-all, and that's just around the corner.

Yes it's really the warm air temps. I know this from experimenting with a queen in cool/cold Holland. The trunk has a heating cable and is wrapped in plastic. The fronds (no protection) have been killed by frost in December/January.

The queen continues to grow (around 1 inch per 2 days) and the new growth is deep green while the outside temps struggle to reach above freezing some days. Warm air greens up the fronds.

    Anyone ever thought to use a Mylar survival blanket around the base of marginal palms like a Christmas tree skirt? Maybe would boost heat to the root zone? Also would keep water off of the root zone too.
