Nipped in the bud

Posted by: Kim Palmer Updated: July 7, 2014 - 10:16 AM

At last! After a string of warm, sunny days, gardens are finally in full flower. I love wandering outside before and after work every day to see which buds have opened. 

My clematis is in glorious red-purple bloom, with more flowers to come. The ligularia and delphinium are about to burst forth, adding golden yellow and brilliant blue to the garden palette.

There are a few red roses in bloom, as well as Endless Summer hydrangeas. Usually mine bloom bright pink, but after treatment last year with the "Color Me Blue" color kit,

they're showing hints of lavender and periwinkle amidst the pink.

But there are definitely some disappointments in the bloom department.

My black-eyed Susans have been putting up big, juicy buds for weeks, but so far, I've seen only one flower. Every morning when I go outside to check on my garden, I find nipped-off stems where the best buds were the night before. Clearly deer are visiting my garden overnight and helping themselves to the juiciest-looking flower buds.

My balloon flowers are suffering the same fate. I've had easily 50-plus buds, but not one bloom so far, thanks to the deer, who leave gnawed-off stems to taunt me. 

It's time to buy some Irish Spring soap, haul out the potato peeler and see if a few shavings in the garden will deter the deer from munching. I had modest success with that remedy last year, although nothing I've tried keeps the deer away completely.

Are you seeing more deer damage than usual this year in your garden? And what, if anything, are you doing about it?

Getting your garden through vacation

Posted by: Martha Buns Updated: July 1, 2014 - 6:57 AM

Welcome home. That’s the message I got from the garden when we got back from vacation last week. We were only gone five days, but what a change five summer days can make.

When we’d left, the peonies had given up and hardly any other blooms were in action. But a burst of heat and some (more) rainfall have opened up the clematis buds and yielded a riot of delphinium, astilbe, coneflower and malva. The pea plants have gone from mere stubs to vines serious about business. And what had been teensy would-be tomatoes are nice dark green hopefuls.

The watering system we’d rigged up in our absence mostly worked, except one plant that a kind neighbor took pity on, so we didn’t come back to dead plants. We put pots inside the raised beds so they'd get the benefit of the timed water lines, which looks funny, but it's effective.

Really, nothing makes me value the garden more than coming home to it after time away. Except did I mention what the weeds did in five days? Eeek.

What have these prolific rains wrought in your garden? And what’s your strategy for getting your garden through vacation?

What is this mystery flower?

Posted by: Kim Palmer Updated: June 23, 2014 - 9:39 AM

Gardens always have surprises up their sleeves. Many of those surprises are disappointing, such as perennials that don't come back or plants that refuse to bloom. 

But some surprises are delightful! Like this beautiful bright yellow flower that opened over the weekend.

This plant has been in my garden for at least a dozen years. I remember the day I bought it. I was shopping with my son, now 21, but a little boy at the time. I told him he could pick something out to plant in our garden, and he chose this plant, because he liked the sunny blooms.

I took it home, without even reading the tag, and we plopped it into the garden, where it bloomed for several years, then stopped. My theory was that it no longer got enough sun -- the maple tree we planted nearby is now huge and shades much of the garden.

But this year, it surprised me and burst into flower, with several buds to follow. The maple tree still shades the garden, so apparently this plant loved the polar vortex, or maybe it was the rainy June. 

Anybody recognize this plant? And what mystery survivors have you found in your garden?

The mystery of the missing buds

Posted by: Lynn Underwood Updated: June 12, 2014 - 2:21 PM

I remember all the hoopla when Endless Summer hydrangeas made their big debut in 2004. Our local Bailey Nurseries developed this show-stopping beauty that everyone was talking about.  It was the first repeat flowering big-leaf hydrangea and would even flourish in northern climates. Word spread that we could have big blossoms from July to early September.

How could I resist?

I bought two from a local garden center and planted them in a primo sunny spot right in front of the house. Summer after summer, the two bushes sprouted soccer ball-sized clusters of pink flowers. Okay - I’m exaggerating - but they sure were showy. Mine were pink because I had alkaline soil. Acidic soil produces blue hydrangeas. One August, my hydrangea blossoms decorated each table at my niece’s baby shower

But after five magnificent seasons, my Endless Summers gradually quit sprouting endless blossoms. Each summer, the number of cauliflower-shaped buds would dwindle.

So I followed some of the tips for “Blooming Success” from the Endless Summer website. I applied 10-30-10 fertilizer a couple of times in the spring. I was really careful not to cut dried stems to the ground until all the new foliage came in since Endless Summers bloom on old and new growth. I covered the base with mulch in the fall and didn’t remove it until May.

But nothing seemed to work. The buds were down to zero. What had changed over the past few years? Then I figured it out. Although this hydrangea can thrive in partial shade, it needs at least six hours of sun a day to produce flowers. I had planted a nearby Linden tree 20 years ago. That tree was now 25 feet tall. Each summer, less nourishing sunlight was filtering through its branches to the hydrangeas.

Once again, my Endless Summers’ foliage looks so green and lush  - but there’s not one sign of even one tiny bud. So I’ve gone from perplexed to acceptance. I’ll never have the soccer ball -sized pink flowers ever again. Unless I climb a very tall ladder and cut off a bunch of thick branches from the Linden tree. And that’s not happening.

Do you have shrubs or perennials that one time produced a riot of flowers but have inexplicably stopped?
Did you move it to a new location and have better luck?

Shrub unexpectedly calls it quits

Posted by: Martha Buns Updated: June 10, 2014 - 8:08 AM

I didn’t see it coming. There were no signs of stress, no previous scares. But this spring, after at least 19 years of reliable existence, a shrub in front of the house just didn’t make it through the long winter.

It’s not as if I had massive die-off from this year’s winter vortex. Even a Zone 5 plant I gambled on a few years ago is back and raring to go. But the shrub that had been a chore to try to rein in, that turned the sun room into anything but sunny, this year just took a dive and didn’t revive.

I can't accuse myself of overpruning it, because I didn't get around to pruning it at all last year. It has a few signs of winter damage, since our yard is apparently perfect rabbitat, but nothing like the rhododendron that’s still going OK, even if lopped off near the ground. Certainly the damage doesn’t look like anything enough to take down the entire bush.  But after several laissez faire weeks of waiting to see if it was just a slow starter, it’s clearly just a bunch of brittle twigs.

Maybe there’s something more systemic going on, since a bush several shrubs down is also only partly reviving. Maybe there’s another pest I’m not detecting, although that shrub is coming back from the roots quite nicely.

At any rate, I’m now in the market for a new shrub. (Oh, rats. An excuse to go shopping.) Any suggestions for a front-of the-house landscaping bush? It’s going into a spot in between a variegated dogwood and a ninebark, just down from a hydrangea. What have you had good luck with? And has anyone else run into a no-show after years of reliable performance?

Or I could be insane and try to dig up the overgrown weigela that's likely to have to come out to reconstruct our porch and attempt to transplant it. Hmm.
