Moonstruck mistake!

Ottawa, ON(Zone 5a)

I've had 'Moonstruck' for several years. First year, the centres of the leaves melted out big time. So I moved it to the east side of my house. It's generally done reasonably well here until recently. A couple of years ago I took a division as a special request and it pouted at me for the entire summer. This year, after a slow, wet spring, it's already melting out in June. (Mind you, all of the hostas in that spot except June are showing signs of sunburn - probably because it was so cloudy and wet for so long then the sun in June was too strong).

Anyway, I'm just about ready to pull this one from my garden completely. Has anyone found the secret to growing it well?

I have to ask, what is "melted out"?

Ottawa, ON(Zone 5a)

The big holes in the white leaf centres. NOT caused by insect pests, but rather from sun exposure.

ah. I had no idea.

That sure looks like snail or slug damage to me. I would think if it was "melted out" (new term for me!), there would be some burning on the plant around the edges of the holes, and I don't see anything that looks burned. I've had problems with slug and snail damage that looked exactly like this, and at the time I would have sworn that there were no slugs or snails since I had never seen one in the area. I put out snail bait, and sure enough, I had about 20 dead snails a couple of days later!

It's NOT slug damage. I've treated them in ammonia/water and I've seen virtually no slugs. If you look closely there is browning around the holes.

I haven't ever grown Moonstruck and have to wonder if it's a hosta similar to Frances Williams in regards to its weakness. I'm relatively new to gardening, but so far FW has only looked nice for me one year in four. The rest of the time it gets wind and/or sun burned in the spring, and I've read this is pretty common.

Ann,

The last time I looked (more of a passing glance) at mine, it looked fine. I'll check it closer tomorrow. I think this is the 3rd year for it in my garden. I don't remember having any reason to put it on my "too ugly to keep" list.

Maybe some kids are sneaking into your garden with magnifying glasses and burning holes in your hosta. hahaha.

I generally only read comments, haven't made one in years, but had to comment here. The plant doesn't look that bad really. One observation I had is: the holes are at or near the crease of the leaves, is it possible the maple seed pods pierced them? I noticed several of the " helicopters" near the plant and have had this happen year after year to my own hosta. . I doubt slugs would bother climbing that high on leaves that wouldn't support them anyway when there is plenty to eat at ground level.

Maple seeds make a tear in the leaf. They usually don't make a long wide hole. I find them stuck in my hostas a lot. Slugs do go up onto leaves, even up on 36" tall leaves.

No experience with Moonstruck, though it is carried at a grower somewhat near here. I'll have to take a look next time I go.

If it were me, I'd probably divide it into a few plants and grow in pots in various protected shady areas to see how it works out in each area.

That sounds like a good idea. But given my experience of dividing it 2 years ago, I'll wait until autumn to divide it up.

It sure is pretty, despite the holes!

Ann,

It has a few torn leaves, but overall it looks good. Even showing some new growth. Mine is at the front of a bed that gets more shade than sun. I'm sure that it will start looking rugged soon, though. We've been having cooler than normal temps, so the whiter ones aren't burning up yet!

It's looking pretty good. As I said, I think the contrast from the rainy April/May to the hot, dry June made a difference this year. The houses are only about 8 feet apart and both have white aluminum siding. I think the sun rays were intensified by the conditions and because the plants were used to shade and rain, they just got fried. But I think I'll divide her in the autumn and try segments in a few different locations.
