Hosta Observation: Less Sun Scalding

Post by andy10917 » August 15th, 2019, 9:26 am

I started regularly applying Nu-Film P as an adjuvant to prolong the effective period of "Liquid Fence" deer repellent, and while it worked well for that purpose, I've also found that there is another nice side-effect to the use of it.

Some of my hosta are in areas that permit too much sun for Hosta, and those perenially have issues with sun-scalding. Those Hosta did not scald at all, or much less (depending on the amount of direct sun) this year.

Follow-up research says that this is an effect from the use of Nu-Film.

It's time next year for an experiment to do with/without testing!

Intriguing.

But you know, Andy, there are other plants besides hostas that actually do quite well in sun. Just a thought! :duel:

Yeah, true. but when you have many hundreds of Hosta plants that require splitting and you're bridging from one garden to another, you're bound to wind up with a few that are in spots that get more sun than they like. I *think* that there is also some Nu-Film effect on Hydrangeas, but it's not as pronounced as the Hosta -- Hydrangeas don't sun-scorch as much as wilt in sun.

I had one hosta that grew so fast and I didn't split it for a number of years - when I did it had 132 eyes. Now all of those "children" have done the same thing. Owwwww, my back!!!

Well, in that case, you just need to create more shade. (Don't hear that too often on ATY.) I've got my share of hostas in a wee bit too much sun but only because I planted them where they will be plenty shaded in a few years' time as their adjacent young trees mature. I've accepted the sun scorching knowing that it's temporary. But, if like you, I had summertime deer pressure and were already spraying Liquid Fence, I'd be all over your new finding.

We are very close to the peak sun angle for the year, and I don't have a single Hosta that has scalded/scorched this year. I have no other explanation than the dialed-in Nu-Film P applications. I'm personally moving this from an interesting observation to a confirmed practice.
