The regeneration begins

by John Davidson

Michelle and other volunteers planted 1100 native plants on the south side of our pond today.

One of the highlights of Fletcher Wildlife Garden—the Amphibian Pond—has undergone a major, and necessary reconstruction since last fall.

Over the years, the pond had become a victim of invasive plant species which had overrun the area, had choked native plant life, and was seriously affecting the viability of the habitat, and the many birds, animals, amphibians and insects that called it home.

As early as 2006, it was clear that the pond was in trouble. An FWG post that year said that “Flowering rush grew exponentially until it covered all open water. frog-bit also became a problem. It and duckweed covered the surface by July, preventing sunlight from getting to the underwater plants that keep the water oxygenated.”

After much debate and analysis, it was decided that the best solution to the problem was to dredge the pond, clearing out the invasive species, and replanting the area with more benign native plants. The dredging was done last fall, and for a while, the pond looked more like a construction zone than a wildlife oasis.

Now, however, the regeneration has begun. And already new, native growth has begun to take hold.

On May 27, an army of Fletcher Wildlife Garden staff and volunteers began planting 1100 native seedlings on the banks surrounding the water. Species included pollinator favourites, like milkweed, sneezeweed, asters, and goldenrods, as well as butterfly hosts, like Pearly Everlasting. Staff also put up a fence to protect the tender plants until they establish themselves. Loose-running dogs and young seedlings don’t mix.

The pond is already once again becoming a magnet for wetland wildlife: frogs, turtles, toads, red-winged blackbirds, and bats have all returned, and even a sandpiper was spotted the other day — a first for the Fletcher Wildlife Garden.

It will take a season for Mother Nature to work her magic. To see it happen, make a point of walking by the pond every couple of weeks or so, watching the new seedlings grow, develop and mature. By the fall—certainly by this time next year—the native plants should have taken hold, and the pond will once again look as if it’s been there, undisturbed, for years.

We are very grateful that a generous bequest from OFNC member, Violetta Czasak, allowed us to take on this complex and long-term project. Thanks also to Diane Lepage, who spent many many hours embroiled in paperwork and negotiations to get the work started.

Scythes vs. dog-strangling vine

by Sandy Garland

Tuesday-in-the-woods day and my trusty crew of Catrina, Mirko, and Kate arrived right on time. Unfortunately, it looked like rain, so we stayed around the centre for a while watering (the plants that don’t get rained on) and potting up more seedlings: Gray Goldenrod and Upland White Goldenrod.

As the sky cleared a bit, we sharpened the scythes and set off for the field north of the woods to do battle with dog-strangling vine (DSV). This week, DSV was over two feet tall and mostly blooming. (Remember, the goal is not to let it set seed.)

We worked around the damp Red Osier Dogwood/Tamarack field, cutting around large clumps of goldenrod and along the narrow grassy area between the shrubs and the road (photo above). We’ve found that goldenrod competes with DSV somewhat, so we try to give this native species an advantage by damaging its competition (photo below).

Catrina scythed DSV around these clumps of goldenrods, while I pulled any DSV plants left at the edges and the few plants in the middle.

In the milkweed field (still north of the woods but east of the centre trail), we again cut DSV along the road. In that field, a group of amazing high school students dug up a large area of DSV several weeks ago and planted Common Milkweed seeds, which are now sprouting. They turned the turf upside down on top of more DSV to double the damage and put down a tarpaulin south of the milkweed patch, in hopes of killing DSV there as well.

Questions we hope to answer

How many times do we have to cut DSV in various areas to keep it from setting seed? Will grass grow back faster than DSV, shading it and making it weaker? How effective is digging up the layer of sod that contains DSV roots? How effective is it to put down a thick layer of mulch after cutting DSV – a possible solution around shrubs?

The woods are looking very lush this week as spring wildflowers take their turn adding splashes of colour to the shades of green. False Solomon’s Seal is still in bloom, as are wild Red Columbines and persistent pink ones that arrived many years ago in someone’s fall leaves.

Growing native plants from seed : cold stratification

A damp vermiculite-filled baggie awaiting seed.

In late October, although we’re still waiting for some seeds to mature before we can collect them, others are ready for their winter treatment.

So what is cold stratification? Essentially, it’s a temperature and moisture treatment used to break a seed’s dormancy and encourage germination. In nature, seeds fall to the ground, where they are covered by leaves and other pieces of decomposing vegetation. Snow falls, covering the seeds with a blanket and insulating them from extreme temperatures and drying wind. In spring, as the snow melts and the sun gradually warms the soil, the seeds germinate and begin to grow!

The need for this cold period to break dormancy is an adaptation to winter. Imagine if seeds germinated almost as soon as they fell off a plant; most plants would die as soon as the cold hit, as they would be too small to have sufficient root mass to survive.

Because we start plants for our annual June sale early, we need to be able to control when they go to sleep and wake up. This is surprisingly easy. All you need are small sealable baggies (we use the snack size), a bowl, a spoon, vermiculite, tepid water, and labels.

Note: The following instructions are for cold, moist stratification, needed by most seeds in our area. However, please check a suitable reference, such as the New England Wildflower Society’s  Growing and Propagating Wildflowers, to find out which species need moisture, which should be stored dry, and which need no treatment at all.

1. Prepare damp vermiculite
Pour some vermiculite into the bowl and add just enough water to wet it. Wait a few minutes as the water is absorbed, then add more water until the vermiculite is damp to the touch. There should not be any standing water in the bottom of your bowl, but the flakes of vermiculite should look and feel moist. Stir with the spoon to distribute the moisture. Vermiculite is a mineral that holds a lot of water, making it ideal to keep the seed environment moist over a long period.

2. Prepare seeds
Remove seed cases and as much debris from the seeds as possible to reduce the likelihood of rot. Some casings contain germination inhibitors, so making sure the seeds are “clean” can be important.

We remove the silk parachutes from milkweed and open all seed pods to release the actual seeds. But we don’t try to pull the fluff off clematis, prairie smoke, goldenrod, or aster seeds.

3. Prepare baggies
Put about three spoonfuls of damp vermiculite into a baggie. Add just enough seeds that every one has lots of contact with the vermiculite. As a rough guide, the volume of vermiculite should be about twice that of the seeds.

We like to shake and then pat down the baggie to maximize contact. Gently push out most of the air, and seal the baggie. You now have a fairly flat, cool to the touch, and moist seed baggie ready for placing in the refrigerator. Don’t forget to label it! We use business labels, because they can be peeled off in spring and attached to our germination containers.

4. Store in a cold place
We have a mini-fridge dedicated to seeds, so moisture levels and temperature are constant (unless someone accidentally knocks the dial). However, your home refrigerator should be just fine, if you place your seeds near the back and away from where moisture tends to collect.

Labeling seed properly is essential. Here you can see our box full of seed baggies!

Now you can forget about your horde until late January or early February!

In early February, remove the baggies from the refrigerator and dump the entire contents into clear sandwich containers. Anything with a clear lid and no holes will work. Label each container so you know what is inside. Again, consult a good reference book to find out which species need light to germinate and which germinate in the dark.

Some seeds germinate almost immediately; others require considerable patience. Keep an eye on moisture levels – keep the vermiculite moist, but not wet. Once the sprouts have at least a couple of mini leaves (they look just like the edible sprouts you buy in stores at this stage) you can begin the next phase which is planting them into a seed starting soil mixture. But that is the subject for another post!

Growing common milkweed from seed – easy steps for beginners

The monarch migration is truly one of the world’s greatest natural wonders, yet it is threatened by habitat loss. . . The need for host plants for larvae and energy sources for adults applies to all monarch and butterfly populations around the world. — MonarchWatch (www.monarchwatch.org/waystations/)

Common milkweed | Asclepias syriaca by C. Hanrahan

If you’ve never grown anything from seed, growing milkweed is a great way to start. You will develop skills applicable to starting other types of plants, and you could become part of a cross-continental chain of waystations dedicated to sustaining the entire lifecycle of monarch butterflies. The FWG is a registered Monarch Waystation. Your garden could be too! Continue reading
