Garden goal roll, 2018

My blog may have withered away to a single annual posting, but at least it's one that serves me well. Every year, I pull together a post detailing what needs doing when, what worked and what didn't, and what I want to do in the future. 

Allium "Gladiator"

April

Dust peonies with copper fungicide to limit blight. Done 4/21/2017. Re-apply in June.

Top-dress spring-flowering bulbs with 3-5-3 when the leaf-tips emerge.  Started 4/7/2018; completed 4/1/2018.

Prune and clean up shrubs damaged by winter snows. On-going!

Treat daylilies infected by Aurebasidium microsictum fungus with Daconil (chlorothalonil)  every two weeks. Done 4/21/2017.  

Sprinkle with a little HollyTone to counteract lime leached from house foundation into flower bed around daylilies and evening primrose. Done 4/19/2018.



Larkspur seeds

Winter-sow larkspur seeds from Monticello. Done 4/14/2018. 

Shape "New Dawn" rose canes. And figure out a support structure.

Feed evergreens along front of house with Holly-Tone. Spread with 8 lbs. 4/19/2018.

Dose "New Dawn" rose with 1/2 cup of Epsom salts in 2 cups water.

Shape "Major Wheeler" honeysuckle slightly but hold off until after blooming to prune back hard to 50%. 

SWS' surplus irises

May

Plant dahlias. Dahlias arrived 4/19/2018!

Top-dress beds with composted cow manure throughout month. Started 4/21/2018.

Review spring bulb performance.  What needs to be replaced or amplified?

Set up front porch and garden table containers.

That stuff that you didn't get to last month?  Do it now.

June

Plant 3 Cathedral white salvia in bed at back of house.

Edge garden beds.

Mid-June:

Spray Pachysandra, periwinkle and rhododendron with Four Seasons horticultural oil to combat scale infestation. Spray again 10 days later.

Cut out deadwood from and thin spirea hedge.

Scratch 1 1/4 cups of RoseTone around the roots of "New Dawn" climbing rose now monthly through the summer; be sure to stop feeding by August 15 in order to prevent developing new growth that will not have time to harden off before fall temperatures drop.

After flowering, shear Amsonia hubrichtii by 1/3 of its height to promote better form. 

When it is 3 feet tall, cut Joe pye weed "Gateway" back to half its height to encourage dense growth.

Stake dahlias when the tubers are planted and again and again as they grow. Stop dahlias by pinching stem back to four pairs of leaves. 

Pinch back shasta daisies to 6". Or just get rid of them?

And stake, stake, stake!

Daylilies

July

After flowering, prune the "New Dawn" climbing rose. 

Prune back 50-80% of "Major Wheeler" honeysuckle after bloom is over.

Late August/Early September

Separate Siberian irises along bed at back of house as needed.

Time to order spring bulbs! 
*   Indoor at least 25 paperwhite narcissus bulbs and 2 amaryllis bulbs
*   Outdoor: 25 Gladiator allium

Plant spring bulbs. 

  

Dig in bone meal around peonies.

Lightly feed evergreens along front of house with Holly-Tone.

Late December

Start planning plant purchases for 2018.

Siberian irises, desparate remedies, and cultivating the art of renunciation

In order not to impact flowering, gardeners are typically advised to transplant Siberian irises in the fall. But what if your Siberian irises have very little impact anyway? What if that dense mat of knotted, fibrous plants is only yielding one or two blooms? Wait to see if more appear? Or plunge in with shovel and knife to carve out new divisions? That was the dilemma yesterday.

I opted for spring transplanting. The week ahead promises to be rainy and cool, so the weather is on my side. After shoveling up a mound, I pulled off groups of two or three outer, younger plants and briefly soaked their roots in water. I added a little composted cow manure and 10-10-10 fertilizer to the soil and poked these divisions back into the ground. Because it takes a year or two for transplanted divisions to flower, I limited myself to a single clump. Now that I see how desperately these irises need to be separated, I know that I have to continue to cycle through the garden clump by clump.

So, in foregoing a strong turn-out of Siberian irises this year and perhaps even next, I am reminded of Thomas Hardy's advice from his lesser novel, Desperate Remedies: “Cultivate the art of renunciation.”  And patience. 

Garden goal roll, 2017

My garden goal roll is more than just a "To Do" list.  Yes, this checklist is very definitely the way that I remember what needs doing when, but it also serves as my electronic diary, where I can record what worked and what didn't.  Sometimes that thing that didn't work is me: my personal rate of success in meeting my tasks is about 40%.  Thankfully, Mother Nature performs to a higher standard.

April

Fall reckoning

A few Indian summer flowers have been finally harvested. This last bouquet offers a reckoning of the season's successes and failures, starting with the blooms arranged in a recycled Tianjin 天津冬菜 jar.

Pickle-pot posy

Dahlias: of several planted, only Kelsey Radiance bloomed.  The others suffered insufficient sunlight, uneven watering, the predations of rabbits.
Next year: just stick to low dahlias in the old side yard.

Salvia farinacea: "Victoria Blue" deserves strong representation in the garden.
Next year: what about adding a white-flowering annual variety, such as "Evolution," "Victoria White Series" or "Jewel White"?

Day lilies: For several--well, for several several--years, the daylilies have been infected by leaf streak caused by Aurebasidium microsictum fungus. At the end of the summer, I sprayed the foliage with Daconil (chlorothalonil) both after cutting down and again when re-growth appeared.
Next year: continue with the Daconil treatments every two weeks and replenish the bed with new fungus-resistant daylilies ( Betty Bennet, Edna Spalding, Ella Pettigrew, Globe Trotter, Nancy Hicks, Pink Superior, Ron Rousseau, Sudie, Tropical Tones, Upper Room, or Winsome Lady).

Streak, blight, fungus . . .

Sedum: Pinching and trimming back is better than not doing either, but that luxuriously full and rounded mound remains elusive. 
Next year: no reason not to shift stragglers lurking around the compost area into real beds.

Compost pile kabocha?

 
And speaking of the compost pile: despite the continuing challenge of balancing dry/wet, green/brown, kitchen scraps/everything else, one discarded seed sprouted out between the bin openings, flowered, and set a cute kabocha squash. Success!
 

Good morning, evening primrose!

What is better than a serendipitous plant discovery?  Maybe receiving a gift of that serendipitous plant discovery!


Evening primrose (Oenothera sp.) in the morning

Common evening primrose (Oenothera biennis) has been on my wish list for years.  Although this American native appears variously as plants tall and short, lovers of damp or dry soils, and with blooms of white, pink, and even blue, my heart was set on a finding a well-behaved specimen that approximated the wild yellow-flowering version.

So how happy was I that last Independence Day weekend my sister-in-law offered a few seedlings of the sunny yellow specimens from her Maine coastal cottage garden in gratitude for a morning of weeding?

Pulling weeds, Harpswell, July 2015

Of the four seedlings that I transplanted, only the one best situated survived our winter. In bloom, it lights up a semi-sunny, well-drained bed.

While this nameless charmer might be a member of the genus Oenothera, I'm not sure of either species or variety. I'm guessing Oenothera fruticosa by reference to its size, leaf shape, soil preference, and sunny disposition. My only regret is that, despite the name, this evening primrose's yellow flowers are usually folding up by the time that I get home.

Closing up for the night
