Seed dispersal with gusto

Some plants passively count on wind, creatures, or water for seed dispersal. Other plants attack seed dispersal with gusto, creating a type of seed pod firework display.

The video below shows seed dispersal with gusto, a process I’ve observed this many times in my Connecticut gardens.

Unfortunately, the video only refers to the plants by common name – violets, touch-me-nots, squirting cucumbers. Searching for information using only common plant names can lead to confusion as common names may vary from gardener to gardener and region to region. For anyone looking to add featured plants to their garden, the addition of botanical names would have been helpful.

In Connecticut, touch-me-nots are also called jewelweed. The Connecticut Botanical Society (CBS) lists two native species: jewelweed or spotted touch-me-not is Impatiens capensis, while pale touch-me-not or pale jewelweed is Impatiens pallida.

CBS also lists many species of violets, most in the Viola family such as the common blue violet (Viola sororia) and small white or northern white violet (Viola pallens). By contrast, CBS does not list poisonous-when-ingested squirting cucumbers (Ecballium elaterium), native to Mediterranean regions.

Seed dispersal with gusto is a fun phenomenon for desired plants. In my landscape, common blue violets add interest and color to the lawn, where I encourage their spread, and where they attract some of the earliest emerging pollinators. But the same blue violets require annual control in perennial beds to prevent them from taking over.

Two of Connecticut’s weedy invasives hairy bitter-cress (Cardamine hirsuta) and garlic mustard (Alliaria petiolata) need only a slight touch to blast mature seeds in all directions, making them formidable weed pests. Hairy bitter-cress blooms during very early spring going from flower to mature seed in just a few days, and re-blooms late-summer to fall from these broadcast seeds. If not caught before narrow seed pods dry, plant removal is impossible without spreading seeds. Garlic mustard is similarly robust in seed dispersal.

Informed gardeners can use seed dispersal knowledge to their advantage by allowing desired perennials to go to seed, or preventing unwanted weeds or perennials from doing the same.

Bug soup

Bug soup is not for the squeamish, but it is one way to control some annoying garden pests –  think bright red lily leaf beetles, Japanese beetles, slugs, and any other plant pest that can be knocked or scooped into a jar of soapy water.

To start your bug soup, repurpose an empty peanut butter jar, or other wide-mouth plastic jar with a lid. Clean the jar, fill it about halfway with water, then add a small squirt of liquid dish washing soap like Dawn.

Bug soup – an empty peanut butter jar, water, and a squirt of dish soap.

Head into the garden, preferably in early morning or late evening when pests are most likely found, with the jar and a small spoon you don’t intend to use again as an eating utensil. Troll your plants for the pests. Once spotted, remove the lid of the jar, place the jar under the bug and tap or push the bug into the water.

The soap makes it difficult for the pests to crawl out of the water. They soon drown.

Replace the lid – this keeps you from accidentally spilling bug soup as you wander from plant to plant – and continue your search.

Keep your bug soup jar outside, where it’s readily available, so it’s easy to grab when taking a garden stroll. Chuck any stewed bug soup after a few hours or every few days – it gets stinky when left stewing too long – then replenish the jar with water and dish soap, and start over.

If lily leaf beetles are your focus be sure to head to the garden in the early morning when they are most active. Lily leaf beetles are bright red and easy to spot, but they tend to drop as soon as the plant is touched so be sure to place the jar directly under the beetle so it drops into the jar or use the spoon to direct the beetle to its demise. And … don’t forget to search under lily leaves for beetle eggs and the excrement-coated larva. A plastic spoon comes in really handy for collecting and depositing these icky masses into your bug soup.

The same goes for Japanese beetles, nearly impossible to capture during the heat of the day when they fly or drop at the slightest touch but less active early and late in the day. Just hold the open jar under the leaf or flower on which Japanese beetles rest and knock them into the jar. I’ve used this method for over a decade and my Japanese beetle population has diminished quite a bit. No traps … just bug soup.

If slugs are your target, use the spoon to scoop and drop them into the soup. Who wants to touch those slimy bodies with bare, or even gloved, fingers? Slugs are best found early in the morning or evening. For heavy slug infestations consider going on slugfari – a slug hunt, by flashlight, after darkness falls.

Making bug soup is standard practice in joene’s gardens, even our 6-year-old granddaughter joins in. Recently, when I saw her returning my bug soup jar to the outside shelf and asked what she was doing, I heard the most matter-of-fact reply, “Catching a slug, Mum-mum. It was eating one of the strawberry plants so I used the spoon to scoop it into the water.”

If a 6-year-old can make bug soup, you can too.
