I’ve spent many of my Bonus Bucks on Hostas from The Farm over the years – and right now I’m watching over them, since they’re having a little bit of trouble. The deer can eat them like candy if I’m not careful, and if I miss a scheduled spray of Deer Off or Scram, my hostas can get eaten to the ground. So I actually have a reminder alarm on my computer to get out there and give them a spritz of deer and pest repellant.
We’ve had a few groupings munched down to the stalks, and I’ve just learned that rabbits like to eat younger sprouts of hostas, so sometimes those nibbles are bunnies, not bucks.
If you have lots of different kinds of hostas like we do, you may notice that the deer prefer some cultivars of the plants more than others. Plant breeders have come out with hundreds of different types of hostas, from green and blue-tinged varieties to large, metallic-tinged plants.
Hostas are the most popular shade perennials, because they get better with age. Over the course of our four years in our Morristown home, we’ve divided our hostas a few times, getting great container and ground plant color and texture in our gardens. They love the low light, the shade, and we have some container hostas doing great in partial sun. When they’re in too-bright sun, their color seems to bleach out a bit.
But we’ve noticed a little something that you should look out for in your own hosta plantings, and mention to anyone you give a hosta plant to as a gift:
Slugs love hostas, too. You may see a slug or snail trail of silvery slime running through your hosta plantings, evidence that these nocturnal pests are munching small holes in your leaves. Slugs can turn your garden into their own buffet, so look at organic pest treatments specially formulated to eliminate your slug or snail issues. Some gardeners still use their grandparents’ favorite slug solution: beer traps. You just fill these little saucer-shaped traps with a bit of beer, the slugs get attracted to the beer, fall in and meet their brewed-up end. [Of course, this solution isn’t smart if you have pets or children in your yard…the organic pest treatment may be preferable.]
If you see irregular notches of chewed-up portions on your hosta leaves, the pest may be black vine weevil, whose larvae feed on the roots of hosta plants, causing yellow, wilted leaves. Organic pest solutions can remove this threat to your hostas.
And if you see evidence of nematodes (microscopic roundworms) on your hostas, which would be brown stripes on the leaves, those plants may need to be pulled up and destroyed (not composted.) To prevent this issue, don’t plant hostas too closely, since wet foliage encourages nematode presence. Several other infestation types are caused by too-close plantings and too-wet foliage and stalks, so spread out your plants well to give them airy room to grow without attracting pest infestations.
Some other hosta tips:
- When planting, don’t place individual clumps too close together
- Give them time. It can take three years for some hosta types to reach their largest, fullest size
- Pull mulch away from the crowns of your hosta plantings, to keep the moisture levels controlled and deter pests as well as root rot and other plant-destroying conditions.
