Happy Combination

,
Sweet Autumn Clematis (Clematis ternifolia) and Autumn Sun Rudbeckia (‘Rudbeckia nitida 'Herbstsonne')

.
Last fall I moved the Autumn Sun Rudbeckia from next to the garage. I added 3 Sky Pencil Hollies (Ilex crenata 'Sky Pencil') to the area because I wanted to introduce some winter interest along the long, gray garage wall. (See October 10, 2009 post “Japanese Holly”.)

I divided in rudbeckia in half. One half went to a friend. I couldn’t decide where to put the other half so I temporarily stuck it in beside the Sweet Autumn Clematis.

It turned out to be a happy combination.

Both plants are tall. The rudbeckia blooms well into fall when sweet autumn blooms. Both plants can be cut to the ground in fall. The yellow and white combination is more outstanding than either one by itself. And, they both seem to like the location.

I think I’ll keep them together.

Praying Mantis

.

I’ve always found Praying Mantis (Praying Mantid) fascinating. As kids we would squeal and drag anyone who would listen into the garden to see the “big bug”.

They are huge (for an insect) and strange looking. Their prayer posture makes them look unassuming. They eat other bugs. Unfortunately they don’t discriminate between good bugs and bad bugs (or relatives). They will sit still and let you take their picture. .

Here are some fun facts from Oregon State University 4H publication:

- Mantids have five eyes—two compound (with multiple lenses) and three simple.
- Mantids are successful hunters 85 percent of the time.
- Praying mantids got their name because it looks like they are praying when they rub their front legs together.
- Mantids are the only insects that can look over their shoulder. A praying mantis can turn its head more than 180 degrees and can see movement up to 60 feet away.
- Female praying mantids sometimes eat males after mating.

Big Tree - Small Space

I’m not really sure what this evergreen is. When I bought it around 1998, I was told it was a Golden Thread Cypress and that it might get 6 feet tall and 4 feet wide. I bought 3 at a great price from a wonderful, old landscape supplier. It is a beautiful gold evergreen, delicate and airy.

But if you plant it in the wrong place, you will have to trim it to keep it a manageable size.

Then you will be stuck with a large green lump.

Overgrown Shrubs

.

I trimmed some shrubs yesterday. I have many of the problems common to old gardens. Paths are closing in, perennials become overcrowded, shrubs grow over perennials. I am constantly dividing and trimming. I know I didn’t put enough thought into mature size. Some evergreens grew larger than advertised.

These 20 year old red-blooming azaleas and (older than that) mountain laurel fill every inch of space our side garden.

They look better with some of the growth removed.

The back of the same garden was overgrown and caused mildew to grow on the house.

.
A little pruning gave them some breathing room.

This fir was our Christmas tree 35 years ago. I left the little white plastic fence at what was once the edge of the garden. I remember how small the tree was when we planted it. It is now taller than the house.

Over the next six months I’ll try to make a plan for spring. Perennials will be divided or removed. I’ll try to decide if large trees or shrubs need to be removed or severely pruned. I’ll need to make some tough decisions. I’ll see what can be saved. It will be difficult to say goodbye to plants. They feel like old friends.

Hydrangea

Has the hot, dry summer of 2010 affected the hydrangeas? You be the judge.

Hot, Dry Summer

.

It has been a hot, dry summer here in eastern Pennsylvania. Several years ago, in an effort to conserve water, I decided to water only new plants, vegetables, plants in pots and a few annuals. I’ve been lucky the last few years. Summer temperatures have been mostly mild and rain has been adequate.

This year we have had several heat waves (temperature above 90 degrees for at least three days). Rainfall was at least 28% below normal in August.

.
It was hard to keep my resolve as I watched the astilbe dry up and fade away. The Sedums are fine as expected. Many plants survive (almost thrive) in the August heat without supplemental watering.

Annuals in the sun:

(Above) Snow on the Mountain (Euphorbia marginata) with a few cosmos sprinkled in.

Dusty Miller doesn’t seem to mind the heat or dry.

Snapdragons hide in the herb garden.

Cosmos and Cleome sometime look a little droopy in the hot afternoon sun but nod prettily every morning.

Perennials in the sun:

Tansy (Tanacetum vulgare).

Yellow Coneflower Rudbeckia ‘Autumn Sun’ and ‘Sweet Autumn’ Clematis
Mums are in bud.

Perennials in shade or part shade in the afternoon

Lily Turf (Liriope muscari) – one tough plant.

Lavender 'Grosso’ planted in 2004 seems to thrive on neglect
Japanese Blood Grass (Imperator cylindrical) in a sea of Creeping Jenny (Lysimachia nummularia) and Mexican Evening Primrose (Oenothera speciosa Siskiyou) ground covers.


There are many more survivors. The plants that don’t make it will have to be replaced with a tougher plant. My garden is no place for sissies.

Sunny Knock® Out Rose

Picture July 2009

Sunny Knock Out® is not my favorite rose.

Picture June 2010

I bought Sunny Knock Out® in May 2009.
.
It has good points. It has been black spot resistant even though it is planted next to roses that have the fungus disease. It blooms all summer. I water the roses periodically but it seems to be more drought tolerant than the other roses and keeps a deep green leaf color.

But - It is not as pretty as some of the other Knock Out® varieties. As the only fragrant variety, I haven’t noticed any fragrance. The bright yellow blooms fade quickly to a dull cream. It doesn’t need dead heading but it looks like this most of the summer.

Chesapeake Bay

.

Chesapeake Bay Center at First Landing State Park, Virginia Beach, VA

The Chesapeake Bay is an awesome body of water with a rich history and wide-spread economic impact. Today, the Bay is said to generate $1 trillion a year into the regional and national economy.

I have been interested in the Chesapeake Bay since I learned runoff from the watershed, which includes Pennsylvania, produces excess sediment and runoff that threatens the bay’s water quality. We don’t often think about how our lawn chemicals, parking lot overflow, fuels, sewage or farm fertilizers affect a large body water. The pollution starts small in local streams and gradually finds its way into the Chesapeake.

.

According to the Chesapeake Bay Program, about runoff:

“Changes in chemical conditions, such as the addition of nutrients, can cause rapid increases in the amount of algae. These algal blooms can have serious consequences. They block light from reaching submerged aquatic vegetation (SAV) beds. Even after they die, they can cause problems. Deposition and subsequent decomposition of large masses of plankton in the mainstem of the Bay can deplete dissolved oxygen, suffocating other estuarine animals.”

A lot has been done in the past few years. Cooperation between state and federal agencies set standards and goals to clean up the 64,000 square mile watershed that stretches from New York to Virginia. According to the Chesapeake Bay Program “Bay Barometer” so far progress is slow but steady.

In May 2009, the “ ‘Strategy for Protecting and Restoring the Chesapeake Bay Watershed’ was developed under the executive order issued by President Obama … which declared the Chesapeake Bay a national treasure and ushered in a new era of shared federal leadership, action and accountability.”

From its glacial beginning through the Indian settlements to the landing of the English in 1607 up to today, the Bay’s natural habitats, abundant fish and game, shipping channels and recreational facilities have been vital.

Hopefully, we will watch the heron fly, see the osprey nest, swim and play, eat blue crab, oysters, bass, and watch the dolphins play in the Chesapeake for many years to come.

Tomato

.
I’ll be on vacation and away from a computer for a couple of weeks. Before I go I want to give you an update on ‘Dan’s Favorite’ Tomato. I bought the plant on a whim in May.

I wrote about ‘Dan’s Favorite’ in a June 9 blog. The tomato is called ‘Dan’s Favorite’. . . It was labeled “mid-season slicing tomato”. I really don’t know what that means. I’ll have to wait for a taste test to see if ‘Dan’s Favorite’ is also mine.

OK it’s the beginning of August. I guess that’s mid-season. It’s definitely a slicing tomato – just the right size for a sandwich. The bush is large and sturdy and full of huge tomatoes.

The ripe tomatoes have green or yellow spots on the outside and hard pink spots on the inside. The blotchy ripening could be the result of a mineral deficiency or uneven watering. It could be both. ‘Dan’s Favorite’ may or may not be more susceptible to this condition.

The tomato was planted in a space occupied by squash and peppers last year, fertilized with fish emulsion. Compost was added last fall and a layer of mulch added this spring after planting.

The month of July was very dry. Usually I’m careful to water regularly. I have a soaker hose laid out in a concentric circle around the plant. How hard can it be? But this was not the year to be able to spend a lot of time in the garden.

The tomato has a good taste. The size is excellent and the yield is bountiful. I should do a soil test. I may have to try ‘Dan’s Favorite’ again next year to see if I can grow them without blotchy ripening.

Creeping Sedum

This sedum has been identified as Sedum sarmentosum. (Please see comments.)

***See June 11, 2011 for more about this sedum. http://bethlehem-pa-gardening.blogspot.com/2011/06/creeping-sedum.html ****
.

I have been trying to identify this sedum for years. Susan Harris of Sustainable and Urban Gardening raised the question again.

Sedum lineare 'Golden Teardrop' shown at Dave’s Garden or Sedum acre.

Margaret Roach of A Way to Garden cited an article from W.J Beale Botanical Garden that makes a point for Sedum acre.

Whatever the name, this little sedum is fast-spreading, drought tolerant and easy to keep in check. It grows in the hot, full sun or in the shade. It doesn't seem to have any special soil requirements. In June, it's covered with tiny yellow flowers.

When it grows over the stepping stones, I hoe around the stones and scoop up the little plants. It pulls out easily.

.

Voila - lots of green for the compost bin.

.

I wish I knew its name. Any thoughts?

Macroweeding

.

A little rain and it’s time for macroweeding.

Here are my definitions:

Macroweeding: The process of grabbing a handful of weeds and yanking them out by the roots.

as opposed to

Microweeding: The process of snatching one weed at a time and yanking

it out by the roots.

I have been macroweeding this week. Sometimes it’s not only weeds that get pulled but overgrown and self-sown annuals. There is a great feeling of accomplishment as you accumulate a large pile of weeds in a short time.

Crab grass and goosegrass look too similar for me to care about identifying them. They are everywhere in this hot, humid weather. I yank, dig, pull, hoe. Here they were mixed in with sweet alyssum. The self-sown alyssum was overgrown so it came out with the weedy grass.

.
Now on to microweeding - Purslane in the rose bed, dandelion in the ground cover, crab grass and creeping wood sorrel at the garden edge, and oxalis among the cosmos call for microweeding – a little more tedious but just as satisfying.

.

Ah, tidy once again.
