Late Night Terror For Foliage

Snails and slugs really crave hostas.

Snails and slugs really enjoy all the new seedlings and fresh foliage that is growing in the garden while the soil is still damp from earlier rain, and the weather is getting warmer. They are neither too smart nor too fast, but they are very hungry, and do their damage at night when no one is watching. They hide before the sun comes up.

The same lush foliage that they eat is also where they often live. However, they also live among lily-of-the-Nile and some ferns that they do not damage very much, as if they think that no one will look for them there. They also hide under any sort of debris and in valve boxes. Removing such debris and unwanted weed foliage diminishes their habitat.

Pieces of damp cardboard intentionally left out in cool and damp spots in the garden overnight can attract snails and slugs as they seek shelter in the morning, and then be flipped over during the day to collect and dispose of the surprised snails beneath. It is sneaky, but effective. People who happen to be up late can hunt for snails while they are out and about. Otherwise, hunting for hiding snails and slugs by daylight takes a bit more diligence.

Saucers or plastic lids containing puddles of beer is supposed to keep snails and slugs out drinking until they get roasted when the sun comes up. The problem is that the beer gets washed away whenever the garden gets watered. Besides, it does not really kill very many victims. Salt around the most susceptible plants likewise gets washed away, and can be toxic to the plants that it is supposed to protect. Keeping water in drainage saucers below potted plants is a problem for drainage, and allows mosquitoes to proliferate.

Copper tape that can be purchased from nurseries or hardware stores is an effective barrier for snails and slugs, but only if the susceptible plants are completely surrounded, and only if leaves or stems that extend over the copper do not touch anything outside. Copper tape can be self adhesive or stapled to wooden planters. Bare copper wire is just as effective. If wrapped around tree trunks, copper tape or wire should have some slack to allow for growth. An extra bit of self adhesive copper tape pressed against itself to form a tab that it can be pulled apart as needed should work well. Copper wire only needs a small loop of extra wire.

Snails, Weeds And Falling Leaves

Gardening does not slow for autumn.

The coloring of foliage is a bit slow this autumn. The cooling nights after such warm weather is bringing some of the deciduous foliage down while it is barely yellowing. Honeylocust and black oak have already gotten notably sparse without much notable color. Hopefully, the more colorful sweetgum, flowering pear, pistache and gingko trees will retain their foliage later into cooler weather, so that they can put on a worthy show before filling compost piles.

It is probably slightly too early to clean gutters and downspouts. Unless the rainy season somehow starts first, this should probably wait until most of the foliage that is expected to fall has already fallen. Lawns, certain ground covers, decks and pavement should be raked as needed though. Decks and pavement can get stained from the tannins that leach from decomposing foliage. Lawn and ground cover do not like the shade under the debris.

However, slugs and snails really dig the mess. Fallen foliage keeps the ground cool, damp and shaded. Raking leaves does not eliminate slugs and snails, but inhibits their proliferation. There are always plenty of other hiding places. As the weather eventually gets cooler and damp, snails that stay out in the early morning should be collected and disposed of. Of course this technique is not convenient for everyone, since most snails hide before the sun comes up. Small slugs hide earlier in the morning and are even more unpleasant to handle.

Once found, neither slugs nor snails are too elusive . . . or fast. Yet, plucking and collecting them is not a fun job. Once collected, no one knows what to do with them. They can be put into plastic bags and disposed of; and will eventually succumb. Some people prefer to simply toss them onto a dry and sunny driveway or roof where they succumb more quickly and get taken by birds. Snails may need to be squashed to limit mobility.

Even though it is too late to prevent most types of weeds from dispersing their seed, a few types continue to disperse seed as they deteriorate through autumn and winter. Weeds in areas that get watered last longer and disperse their seed later than those without watering. Perennial weeds that are still green in dry areas areas will be easier to pull after the first rain.

Banana Slug

P90421They are not as dangerous as they look. Really. If they were, just one could do more damage than an entire herd of average slugs. The fortunate truth is that banana slugs consume only decaying plant parts and fungus. Yes, they literally cruise about the garden eating bits of decomposing debris that we may not want there anyway, and converting it into a very nutritious and nitrogen rich ‘fertilizer’. They are actually beneficial to home gardening.
Of course, this does not necessarily mean that we ‘want’ them in our gardens. They really do look scary. This one is only about four inches long, but larger ones can get nearly twice as long! Some rats are not that big! Their bright yellow color, which is typically brighter yellow than this one is, is an expression of defiance. They only stay out of the way because they prefer damp and shady situations. Otherwise, they do not care if we see them.
Contrary to popular belief, they do not really taste like chicken. They taste more like the blandest of escargot. If not purged with corn meal and partly deslimed with vinegar, they can taste much worse. Even if the myth about the slime on their undersides containing more vitamin C than a bucket of oranges is true, it does not justify licking them. It is more degrading to you than it is to them; and no one needs that much vitamin C anyway!
As revolting as they are, they are not completely disdainful. It is fun to point them out to friends who have never seen them before, but only after they have gotten close enough to be startled, and jump away as if being chased by something that can actually move . . . quickly. Banana slug races are also fun.
