One of my two needle palms lost its spear on the main plant recently. It's seemingly had a harder time establishing than the other, losing a lot of fronds in our record-breaking summer despite my frequent watering of both. I've heard they can grow a new spear, but I'm worried about fungal infections in the meantime. Does hydrogen peroxide help prevent them?

One of the smaller plants from the same root system seems fine, as does my other needle palm, but they didn't lose a bunch of fronds in our horrid summer. Even if the smaller plant dies too, I could always take a cutting from my other one and grow it, but I'm just so worried.

Any help is greatly appreciated. Thanks.

It can be done if you use the proper dilution ratios which is extremely important. This gardener has some excellent advice (and he explains the reasons WHY) about what are the best dilution ratios and daily application routines and programs he uses so as to avoid causing H2O2 damage to the plants while getting the anti-fungal benefits from it. He also has information about other types of products he may use in his gardens for other problems:

Have you checked the underside of the fronds for spider mites? They are very attracted to palms and thrive in hot weather. Could that have been the problem this summer. I gave up trying to grow them because of that.

Why do you think a fungal infection is probable? Won't they go dormant in the winter? I don't know that I'd do anything with it at this point since colder weather is on the way unless of course you see a problem.
