High Summer In The Garden

Last year about this time I wrote about the Million Pollinator Garden Challenge. I hope at least some of you are also participating, either formally or simply by planting some nectar rich flowers and providing for wildlife in your landscape.

Rudbeckia 'Indian Summer' and PollinatorHigh summer here in Birmingham brings sizzling heat and lots of it, along with the welcome abundance of life in pollinator gardens. In mine the perennial summer phlox, coreopsis, coneflowers, butterfly weed, salvias, rudbeckias, and daylilys are abuzz.Zinnias and Skipper

 

Annuals, especially those in the sun, are also capturing bee, butterfly and hummingbird attention, and I try to plant a variety for each in my sunniest beds.  Angelonia, gomphrena, zinnias, batface cuphea, Mexican heather, purslane, and more jockey for space.

This is the tail end of daylily season, and on summer evenings I pull off unsightly yellow leaves, faded blooms that might be hanging on, and then cut spent scapes to the ground.

Kris' Garden - JulyAfter they’re completely through blooming, if foliage looks rough, I’ll grab a handful, twist it, and cut it completely off. It will reflush with more sightly looking leaves lasting until the end of the season. Remember, you see foliage more of the year than flowers on most perennials. Plan for that when deciding where to plant them or if you’re dividing and/or moving them.Stressed Gomphrena

If it’s been very dry, the early morning hours are spent watering any plants that look wilted. If they’re left without water too often, the stress will weaken them and they’ll be more susceptible to disease and insect attacks.

I’ve noticed some of the small white gomphrena that I planted quite late are struggling. I don’t think they’re getting enough sun, and they’ve gotten parched  more than a few times. I’ll be keeping an eye on them.

Summer Phlox and BeesThe summer phlox and coreopsis are in full bloom and the bees love them. I watch tiny skipper butterflys light  on the coreopsis; they move so fast! When these two play out I’ll cut the faded flowers off the phlox and wait for a second, smaller display.Bee on Coreopsis

The coreopsis will be sheared back since there are too many small flowers and not enough hours in the day to deadhead each one.

As with most summer blooming perennials, I’ll cut stems back completely to neaten the garden and give late blooming plants room to shine when the weather finally cools.

 

 

imageHonestly, though, it’s really too hot to do much more than water, deadhead, and pull opportunistic weeds that seem to come out of nowhere. Even as I water I’m dreaming of my vacation north to see family and friends. I know my garden will be here when I return, grown even more lush with high summer’s heat and, hopefully enough rain too.

Perennial To-Dos For A Great Garden…

Perennial chrysanthemums benefit from being cut back once or twice or they tend to get lanky with fewer blooms.

May and June are key months to keep an eye on your perennials as they’re coming up and (hopefully) growing like gangbusters.  A few tasks to do now involve some summer perennials and many of your late blooming fall plants. Of course, the  following tips are not something you have to do, but are only suggestions gleaned from my gardening experiences through the years. Remember, gardening is not one-size-fits-all!

Do you have summer phlox in your garden? Now is the perfect time to selectively thin your clumps, especially if they’re large. (If they are outgrowing their space or haven’t been blooming well, divide them this fall.)

To thin your summer phlox, simply reach into the clump and pull out the smallest stems. This effectively allows better air circulation – which in turn leads to a healthier clump less prone to mildew problems. At the same time, cut back by half some of the remaining stems. A longer bloom period will be the result…

For more blooms on your late blooming perennial sunflowers, salvias, asters, Joe pye weed and chrysanthemums,  now is the perfect time to get in the garden and cut them back – if you have large areas, use a hedge clipper and cut them back by half. (Hedge clippers – the old fashioned manual ones –  work best on asters and perennial mums.) When you cut a stem, it will respond by creating two stems, so you’ll have a fuller, shorter plant with more flowers later.

Now you don’t have to do this, (I’m not the garden police!) and, if you don’t, they’ll just be taller and bloom earlier in the fall, growing to their full height in your garden.
I do like cutting mine back now though. I also make a second cut-back on half the clumps about a month later. This effectively “staggers” the bloom time – those not cut back this second time will bloom first, and be a bit taller, and the plants that are cut back the second time will bloom a bit later.  More blooms, longer! It’s a win win!

Many southern gardeners say “Don’t cut late blooming perennials back after July 4th”.

Rule breaker that I am, I have cut perennial mums, asters and sunflowers back as late as mid-July and had no ill-effect. But I like extending my blooms well into fall – it’s one of my favorite times of the year!

Above all, enjoy your garden – after all, that’s what you planted it for, right? Hopefully by following these tips you’ll be able to enjoy it even longer!

Perennials – Plant Some Now!

Mexican sage, Salvia leucantha 'Santa Barbara'

First things first…what is a perennial? Well, a perennial is any plant that will be with you for the long haul – some will disappear completely during the coldest months of the year and reappear with the first warm days of late winter.

Herbaceous perennials have a specific bloom period when they offer their largest show, then continue to grace the garden with their foliage the rest of the season. Or, their foliage will be the show through the summer and their bloom time will be in fall.

However and whenever they bloom though, please understand that for the majority of their life you’ll be looking at the shape, texture and color of their leaves. When you’re deciding where to place them this is one of the most important things to remember!

Used well, perennials are a wonderful addition to a landscape filled with trees, shrubs and annuals. They add their period of bloom and, when grown well, should get larger with each season. (We’ll talk about dividing your perennials in another post.)

However, perennials are not no-maintenance plants. Some, like Japanese aster, thread leaf coreopsis, catmint and dianthus need shearing back after bloom. Others, such as daisies, coneflowers and rudbeckias appreciate general dead-heading (Cutting off individual blooms.) to keep them blooming longer. When they’ve finally played out the entire stems need to be cut to the ground. Butterfly weed, Asclepias tuberosa, benefits from deadheading blooms if you don’t want it to reseed. Monarch butterflies lay their eggs on it, so deadhead below the bloom only.

Still others benefit from being cut back by at least half early in the season to control height, or this can be done with half the plant to create a staggered bloom time. Many late season bloomers fall into this category. These include many of the tall salvias, perennial sunflowers, tall rudbeckias, pink muhly grass and joe pye weed (Eupatorium). These late blooming perennials are quite beautiful in combination with perennials grasses.

Summer phlox is one that benefits from up to half its stems being cut back early in the season. This promotes good air circulation, which in turn helps to prevent mildew problems on the leaves.

None of these tasks is difficult, and, if they’re done a little at a time, your plants will look well tended and cared for.

If you’re in the Birmingham area, please stop in and take a look at the perennials in stock now. The selection of plants is excellent!

Some favorites for part sun to full sun:

Don’t let the latin names intimidate you!  They are just the best way of knowing for sure what you are asking for. Common names, though easy to remember,  can bring on even more confusion when there’s more than one plant with the same name…at any rate, try a few perennials in your garden soon – you’ll be hooked in no time!

 

 

This is just the beginning of the perennials that are out there. Ask us for advice if you need help choosing – we’re happy to advise you on the right choices for your garden. And, if you’re adventurous, try one even if you’re not sure if your spot is exactly right – plants don’t always follow the rules!
