The hostas in my shade garden are ragged and full of holes every year at the end of summer. Is this normal?
It’s not unusual to find holes in big, leafy hostas. Those large, wide leaves create a cool, moist shelter for slugs and snails, who may rest under them during the heat of the day and come out at night to dine. You can verify their presence by placing a small board beside the hostas where you’ve noticed damaged leaves. In the morning, turn the board over to see how many have gathered on the underside of the board. Dispose of them as you wish. Another option may be to set out a small dish or a shallow aluminum can (such as a tuna or cat food can) filled with beer beside the hostas. Slugs in the area may be lured by the beer to crawl into the can, and you can dump them all in the trash.
The American Hosta Society suggests several solutions for protecting plants from slug damage, one of which is to provide something else for them to eat, such as lettuce. A different strategy focuses on placing a barrier around vulnerable plants. Strips of copper on the ground can be effective because slugs don’t like to cross it; diatomaceous earth or table salt sprinkled around the plants also may keep them away, but be careful about adding too much salt to the soil.
The American Hosta Society mentions a couple of poison baits, but also suggests that a 10% solution of vinegar, sprayed on the slugs, stops them in their tracks – but you have to be out there with the spray when they are out, which is usually at night.
A final suggestion is to set a trap. Place two boards together with a small stick between them, where the slugs can crawl into the cool shade. Then, when the slugs are between the boards, remove the stick to trap and dispose of them.
The Nashville Tree Foundation announces the opening of the Betty Brown Tree Trail and Arboretum, a leafy respite next to the newly developed Riverfront Park and Ascend Amphitheater in downtown Nashville. The meandering trail, Named after
NTF’s founding board member and first president, the late Betty Moorhead Brown, includes 236 trees representing 36 different species. A dedication ceremony is planned for later this month, but Nashville Public Television’s Volunteer Gardener program has already taped a segment at the Trail. The segment will air on Sept. 17 at 7:30 p.m. and again on Sept. 20 at 9:30 a.m.
For visitors to the Trail, Nashville Tree Foundation has developed a guide pamphlet that lists the tree species and what to look for along the way. When you visit, pick up a pamphlet at the visitor’s kiosk, or download it here at NTF’s website.
