It's Not too Late to Move those Plants! - Sept. 11, 2023

As plants grow and bloom and show us the error of our ways we realize that we really need to move some plants.  They would just look better in another spot. Sometimes we’re off by a matter of inches, or sometimes many feet. Don’t live in regret, though. The next time you think, Why didn’t I plant that here instead of there? Just dig right in and fix it on the spot.   You can move perennials in late summer. The soil is warm so plants will settle in faster than if you moved them in the Spring. I call it designing with a shovel. Go ahead and move those bright Asiatic lilies behind the cool blue campanulas, or partner the deep red rose with Shasta daisies.

 

But there are a few guidelines to follow to ensure success:

1. Pre dig the hole where the plant is destined.

2.  Fill two buckets of water and presoak the hole before you move any plants.

3. Once you dig up your perennials replant it quickly so the roots don't dry out.

4.  Water thoroughly again,  Water daily if temps remain warm.

Good candidates for transplanting:

  •  astilbe, peonies, bearded iris, bleeding heart 

  • agastache

  • artemisia

  • Asiatic lilies

  • Monch aster

  • bee balm

  • bulbs

  • Goldsturm black-eyed Susan

  • cardinal flower

  • campanulas

  • thread-leaved coreopsis

  • daylilies

  • feverfew

  • liatris

  • mums

  • obedient plant

  • phlox

  • coneflower

  • sedum

  • Shasta daisy

  • Siberian iris

  • veronica

  • yarrow

"Mulching/Chelsea Chop/Vitamin G" - June 2023

Mulching garden beds:

Mulching suppresses weeds by blocking out the light and keeping in moisture by reducing evaporation.

At its simplest, mulch is any material that covers the soil’s surface. In nature, mulch is simply fallen leaves and plant debris. In the garden, mulch can also include compost, wood chips, rotted manure, cardboard, or even seaweed. If you use organic mulch material - one that will break down - mulching will improve the soil structure and  help retain moisture.

The Chelsea Chop is a method of pruning that limits the size, controls the flowering season, done at the end of May at the time of the Chelsea Garden Show in  England.

Perennials to give the Chelsea Chop:

Garden Phlox, Yarrow, Bellflower, Aster, Coneflower, Black -eyed Susan, Upright Sedum, Penstemon, Golden Marguerite, Sneezeweed (Helenium), Goldenrod (Solidago), Shasta Daisy (Leucanthemum)

"Vitamin G" - Health Benefits of Gardening

 

An RHS study, in collaboration with the University of Sheffield published last year showed that adding plants to a paved front garden could reduce stress levels as much as eight weekly mindfulness sessions.

Royal Horticultural Society (RHS) wellbeing fellow and lead author Dr Lauriane Chalmin-Pui said: “This is the first time the ‘dose response’ to gardening has been tested and the evidence overwhelmingly suggests that the more frequently you garden – the greater the health benefits.

“In fact gardening every day has the same positive impact on wellbeing than undertaking regular, vigorous exercise like cycling or running."

“When gardening, our brains are pleasantly distracted by nature around us. This shifts our focus away from ourselves and our stresses, thereby restoring our minds and reducing negative feelings.”

Those with health problems stated gardening eased episodes of depression (13%), boosted energy levels (12%) and reduced stress (16%).

“Most people say they garden for pleasure and enjoyment so the likelihood of getting hooked to gardening is also high and the good news is that from a mental health perspective – you can’t ‘over-dose’ on gardening.

“We hope all the millions of new gardeners will be getting their daily doses of gardening this week and feeling all the better for it.”

"Planting a Wildflower Patch" presented on March 2023

                        

 

A field of wildflowers is a magical place...

filled with color and busy with the sight and sounds of all sorts of creatures going about the day’s business. It’s such a soothing scene, it’s easy to wish that you could have a meadow of your very own, right in your own backyard. The good news is, you can! Native bees and other pollinators are essential to the successful production of many fruit and vegetable crops and the reproduction of many plant species in our surrounding environment. Wildflower meadows and gardens are extremely valuable habitat, providing nesting sites and a protected environment for hundreds of bee species, moths and butterflies, and other insects. Many birds, bats, small mammals and some amphibians also thrive on the food and shelter that a meadow ecosystem provides. native wildflowers have co-evolved with an area's climate and pollinators, they usually require less water and fertilizer ... Even if you only have a small plot available for planting, you can transform it into a mini-meadow. Better yet, on a large scale, a wildflower patch could be the lowest-maintenance garden you’ll ever plant.

 

As wildflower enthusiasts like to say, "If you can grow weeds, you can grow wildflowers." It isn’t actually quite that easy . You can ignore it up to a point but the more hands on you are the more colorful and life filled your meadow will be. Ultimately if you do ignore your wildflower area it will eventually become less colorful,and soon you will have weeds and brambles. To manage your wildflower area you should cut the meadow and low as possible in the late Fall. Rake the area and cut it again with the lawnmower. Rake once more. Raking off the cuttings gives your ground light and space for new seedling germination and growth the following year. It reduces the thatch and organic matter that will eventually favor grasses over wildflowers. A wildflower meadow does not want a rich organic soil.

 

Note:  Yellow Rattle: Meadow Maker widely used in the UK , native to the Northern Hemisphere it is found in Alaska and a few areas in the Pacific Northwest. It is a semi parasitic annual plant that weakens grasses by attaching their roots to the roots of grasses, thereby robbing them of nutrients. This reduces the vigor of existing grasses and allows wildflowers to gain a competitive advantage. Can be sown before the fall rains, but can also be planted in the Spring and doesn’t need to be cold stratified (kept in fridge for 2 weeks.)

Steps for Building a Wildflower Garden

  1.  Choose a Location -You don't need a huge meadow to have a wildflower garden: Any space with decent drainage and at least six hours of sun a day will do.

  2. Plant wildflowers: ▪ Instead of lawns. ▪ Between property borders. ▪ Surrounding a deck. ▪ In an open bed. Full sun

  3. Remove Weeds -No need to amend the soil: Some of the most beautiful wildflowers appear in rocky banks along the side of the highway. If anything at all is growing in the place you'd like to plant, so will wildflowers. Do remove as best you can any weeds before you plant.

  4.  Select Native Plant Seeds -Pick a wildflower mix with plants native to your area. Many companies and garden centers offer wildflower seed mixes, often featuring plants that do well in our region. Northwest Meadowscapes and American Meadows are two good online seed sites for ordering

  5.  Sow the Wildflower Seeds -Scatter a mix of annual and perennial wildflower seeds in your space. Annuals should be planted after all danger of frost has passed. Perennials can be planted at the same time and anytime through September. ▪ Spring-planted annuals will bloom the first year and should be reseeded every spring. ▪ Perennials probably won't flower the first year, but you'll be able to count on them for many years to follow.

  6.  Tamp the Scattered Seeds -Don't cover the wildflower seed with dirt or fertilize. Simply tamp the seeds down by walking over the areas you've seeded.

  7.  Water the Seeded Area -You'll still have to water, but not much. When you first plant your wildflower garden, water as you would a new lawn. Once the seeds have achieved around four inches (5cm) of growth, no more watering is necessary. Wildflowers will thrive on the natural rainfall.

  8. Weed, as Needed -You'll still have to weed, but not much. Some wildflowers are classified as weeds, so it can be difficult to know what needs to get yanked out. A good rule of thumb is to pull those plants that grow in clumps instead of evenly spread through your garden bed--those intermittent interlopers were probably not sown by you. Benefits of a Wildflower Patch ▪ Within a year of putting in a wildflower garden, you'll notice an uptick in the birds, bees, and beneficial insects visiting your garden. ▪ In your new wildflower meadow, you'll discover an extremely low maintenance flower bed that may just turn into the focal piece of your landscape.

"Planting Hardy Cyclamens in your Garden"

Presented February 13, 2023

cyclamen pic.jfif

Cyclamen coum:

Hardy cyclamen is a pretty hardy perennial, bearing delicate silver-lined dark green leaves and dainty blooms in shades of white, various shades of pink and red, from late winter to early spring (January thru March). On average, cyclamen flowers last for as long as 6-8 weeks. But some can bloom for up to 3 months in the ideal conditions. The plants themselves can live for decades.

 

  • Cyclamen hederifolium -blooms in the Fall

  • Cyclamen persicum -  is often seen for sale in florists shops, they are best enjoyed as house plants as they usually aren’t hardy.

 

Where to plant cyclamen:

Plant cyclamen coum in humus-rich soil in partial shade. It's perfect for growing at the base of small shrubs and trees, and naturalizing in grass. Mulch annually with well-rotted leaf mold to prevent the tubers from drying out in summer, and from winter cold.

edelweissperennials.com- good source for buying cyclamen online

Garden Chores for February:
 

  • Dig and divide hostas

  • Prune roses

  • Prune group 3 Clematis

  • Deadhead hydrangeas 

 

Common varieties that require cold stratification for spring planting:

What Is Cold Stratification?

Cold stratification, also known as seed stratification, is the process of exposing seeds to cold and moist conditions to encourage germination. In nature, the stratification process takes place when fallen seeds overwinter underground or beneath a layer of snow. In the spring, the temperatures rise, thawing the ground and breaking the seed out of its dormancy period. The seed sheds its hard seed coat, beginning the germination process. You can mimic this process indoors to prepare seeds for propagation.

How to Stratify Seeds in the Refrigerator

Follow these steps to cold stratify your seeds in the fridge.

  1.  Place the seeds in a damp medium. Small seeds can be sprinkled onto a damp paper towel. Larger seeds should be placed in a moist medium such as damp sand or vermiculite. Ensure that the medium is moist but not soaking wet.

  2.  Store the moist seeds in a plastic bag. Once your seeds are wrapped in a damp paper towel or planted in a moist growing medium, place them in a plastic bag. To prevent excess water from accumulating inside the bag, allow for some airflow by leaving the bag partially open or puncturing the bag with a few small holes.

  3. Place the bag in the fridge. Most seeds require about a month of cold stratification to increase germination rates. However, the exact amount of time needed for the stratification process will vary depending on the type of seed you choose. Consult the cold stratification timeframe suggested on the seed packet. Check on your seeds periodically and if they start to sprout, remove them from the bag and plant them.

Cindy says.."Plant a Tree!"

 

1-   Trees hold soil in place

2-   Trees sequester carbon dioxide

3-   Trees produce oxygen

4-   Some animals are dependent upon trees

5-   Trees make cities more livable

6-   Trees increase property values

7-   Trees help to save energy

8-   Trees are important for physical and mental wellness

9-   Trees feed us

10 -Trees create a sense of place

11- Trees are an investment for our communities and for future

      generations

12- Trees help to slow stormwater runoff

13- Trees clean the soil

14- Trees are beautiful

Chores for December:

Pull any weeds that remain in your garden. On a sunny day they come out of wet soil more easily than out of dry soil, but don't walk on wet beds (soil compaction)

Plant bare root trees and shrubs if soil is soft enough.

Evaluate your garden beds, what worked, what shrubs need to be moved or removed (outgrown their space) this is where taking photos throughout the spring and summer can be a good way to record plantings.

Fall Foliage

Garden Chores for October

Presented October 10th, 2022

  • The days are still warm but there is no denying that the wet and shorter days are not far behind.  This is a busy time in the garden:, moving plants, planting new ones and putting the garden to bed.

  • Keep deadheading throughout October, particularly  dahlias. This will extend their flowering season

  • Collect seeds from perennial plants, using paper (plastic) bags. Always label seed packets immediately. Store in a cool, dry place until ready for sowing.

  • It is not too late to take cuttings and it is  a very satisfying process if it is successful. Choose healthy non-flowering growth, use a sharp knife and keep the humidity high by frequent misting or a cover.

  • Remove annuals as they fade and as you clean up beds add a good layer of compost.  This will act as a mulch for the winter and help suppress weed seeds.

  •  If you haven’t ordered bulbs it is getting late for that chore.  You can still find packaged bulbs in many of the nurseries and they can be planted anytime now. .

  •  You can dig and divide a lot of perennials now, I usually wait on Hostas until early spring.

  •  Astilbes, Siberian irises, Japanese irises and daisy clumps are all good choices for the Fall.  Be sure to add additional compost into the hole after dividing and give them a good soak.  Irises benefit from dividing as the clumps can become congested. If you notice that you aren’t getting as many blooms that is an indicator that they would benefit from division.  Use a sharp shovel to cut through the center of the plant.

  • Remember to rake leaves and add to compost or chop with the lawn mower and use as a mulch

  •  Make sure trees (newly planted or young) and shrubs are well watered going into Winter,

  •  Clean up beds to avoid providing places for slugs and snails to winter over

  • Plant Fall bulbs & perennials

  • Mulch beds with compost 

  • Divide perennials

  • (daylillies, iris, hostas)

  • Continue weeding!

"The Chelsea Chop"

Handout provided by Cindy 6/13/2022
 

Cut the plants back by a third or half to delay bloom and limit size.

"The Chelsea chop (so called because it is usually carried out at the end of May, coinciding with the RHS Chelsea Flower Show) is a pruning method by which you limit the size and control the flowering season of many herbaceous plants."

  • pennstemon

  • phlox

  • campanula (bellflower)

Benefits:  Leggy perennials tend to not be so floppy as they grow shorter
                    Delayed flowering will extend or stagger bloo
m times

 

Good candidates for the Chelsea Chop:
 

  • asters

  • upright sedums

  • heleniums

  • goldenrod

  • shasta daisy

  • rudbeckia

chelseachop.jpg

Method 1

Chop back clumps of perennials by one-third to one-half using shears. This will delay the flowering until later in summer and keep plants shorter and more compact.

Method 2

Cut only half the stems back on a plant, which will extend the season of flowering rather than delay it.
