3% Peroxide and Copper Fungicide

[Mbiles]

I have 200 Windmills planted on our farm in SW Georgia. We had 7 inches of snow on Jan 21. The next two days temps got above-freezing but below-freezing at night. They look Bad. Should I pull the spears and pour 3% Peroxide down in the bud? And spray them with Copper Fungicide? Or pull the spear and just use Copper Fungicide spraying in the bud and trunk?  I'm new at growing Palm Trees any help is Greatly Appreciated.

200 isn't so many. I would just walk the rows and give spears a tug. Pour a little peroxide in each one. No need for Cu fungicide. I'm in the ATL metro area and I see regrowth between Memorial Day and July 4th. If you're south like Tifton or Albany, I'd expect recovery in early May.

If the spears want to remain in the palm don't pull them.  If you give them a gentle tug and they come out then treat with copper fungicide.  If they don't them leave them be.  You can go ahead and spray with copper fungicide as a preventative measure.

Snow doesn't bother Trachycarpus it's common in their native habitat.  It's more to do with the ultimate minimum temp and duration of the freeze.

@Mbiles I agree with the others above.  If the spears pull, then definitely dose them with either hydrogen peroxide, Daconil, or copper-based fungicide.  I like to use a mix of 4tsp Daconil concentrate per 32oz of 3% hydrogen peroxide.  Copper is good on all, just don't repeat it too often.  High doses of copper fungicide can eventually be phytotoxic.  There's no harm in preventative fungicide doses of any of the above three.  There are other systemic fungicides like Banrot and Aliette/Fosetyl-Al and others, but bud rots seem to respond well to surface treatments.
