Overcrowded iris?  If you saw less flower production and the rhizomes are coming completely up out of the ground, then you might want to divide them!

Overcrowded iris

Iris should be divided every 3 to 4 years.  First cut the foliage fans back to about 3 to 6 inches.  Remove any yellow or dead leaves.  Gently dig out the rhizomes.  Cut them with a sharp knife leaving them each about 3 to 4 inches long.  Remove any mushy parts, hollow tubers or those that may have grubs.  If you’ve had fungal issues, treat the rhizomes with a fungicidal powder before replanting.  Use a 10% bleach solution after each cut.

To replant loosen the soil to about 8 inches, leave about 2 inches of roots and give them room…  plant the rhizomes so that they are just barely under the soil.  Don’t mulch!  This sounds counter-intuitive but irises need a dry period.  AFTER the ground has frozen you can mulch to prevent heaving.

Reblooming Iris ‘Aggressively Forward’ – kind of an odd moniker but gorgeous flower!

 

If your irises are just fine, then leave them alone.  Let them die back on their own.  For more detailed information on all things Iris click HERE [Univ. of MN Ext]

Have you tried Reblooming Iris?  They will bloom intermittently from midsummer to frost.   Check your local garden center for rebloomers!  I’m seeing sales on them now through mail order…

Move over poison ivy, here comes poison hemlock.  The Minnesota Department of Agriculture (MDA) is warning residents about the dangers of poison hemlock (Conium maculatum), a toxic member of the carrot family.

Poison hemlock flowers

In fact, their press release warns residents to be on the lookout for the weed, take extra precautions when handling it, and not ingest any parts of the plant.  This is no small weed either, Poison hemlock can grow to 8 feet tall.  The flowers are small and white with umbrella shaped cluster on the tops of stems.

Poison hemlock stems

The stems are hairless and have purple blotches. The plants emit an odor. The flowers of poison hemlock look similar to wild carrot (Daucus carota) and water hemlock (Circuta maculata). However, the fern-like leaves and purple blotches on the stems of poison hemlock distinguish it from these related species.

Poison hemlock leaves

The weed has been recorded in isolated pockets of Minnesota, most recently in the southeastern part of the state. It appears to be spreading quickly. It’s also in parts of Wisconsin and elsewhere.  If residents suspect they have found poison hemlock, take a picture of the plant and email it to arrest.the.pest@state.mn.us, or contact your local Extension office.   Check out the University of Wisconsin Extension with more information.

Poison hemlock is very toxic to humans and livestock. Symptoms of toxicity include: nervous trembling, salivation, pupil dilation, rapid, weak pulse, and eventually leading to coma or death.

Poison Hemlock looks suspiciously like Queen Anne’s Lace.  You don’t want to get the two mixed up!

I had the opportunity to interview Don Engebretson, the Renegade Gardener about one of his books “Tree and Shrub Gardening in Minnesota and Wisconsin”.  You’ll understand why he’s the “renegade” after listening to the interview!  I’ve attached the podcast of our chat at the bottom of this page.

This book is co-authored by Don Williamson and is not only filled with 850 trees, shrubs and vines to envision in your landscape but it’s also a wonderful tool to guide you in your planting and pruning.  There’s also a section on Pests and Problems.

There are many varieties that were never on my radar.  Now they are!  The Fringe tree or Chionanthus…

Fringe Tree aka chionanthus

I love the multi-stems on this tree and the “Santa beard” flowers.

‘Santa’s beard’ flowers

The “Dons” have written 3 books in this style.  Of course, this one on Trees and Shrubs and also Perennials and Annuals.

Always look to buy books locally first, same as plants!  Did I mention there are great photographs in the book as well.  Oh and a section on problems and pests too.  The book vets about 850 different plants from American Bittersweet to Yews.  What you won’t find are edible fruit trees.  These are all ornamentals but boy, howdy, are they ornamental!  Of course there’s always a slight exception – one of the shrubs listed produces nuts.  The Hazelnut also known as Filbert is native and features tasty nuts, if you’re patient and plant male and female varieties.  The unique twisted branches of the corkscrew hazelnut adds amazing winter interest.

have to give props to the people who propagated these new petunias!  They’ve come a LONG way in a couple of decades!  German breeders have added some stunners.  2017 has seen a plethora of pretty petunias beginning with ‘Night Sky’.  It’s nothing less than breathtaking as it really looks like a night sky.  Purple or dark blue with random white spots, each flower is different.  It’s full and mounding and reaches up to 16 inches tall with a spread of 2 to 4 feet.

I was just recently at a bridal shower and the woman hosting it had this beauty!

Night Sky

I have to show you this to you up close!!!!

The crazytunia series has been adding some crazy combinations over the last several years.  For 2017 they added ‘Cherry Cheesecake’ – a sweet white flower with the edges nipped with red.  This one grows to just 10 inches with a spread of 2 feet.

‘Cherry Cheesecake’

‘Moonstruck’ has a yellow center that blends into purple petals and ‘Citrus Twist’ is bright orange with yellow and red tones.

‘Citrus Twist’

Calibrachoa are closely related to petunias, in fact, looking just like tiny ones!  I love these.A new offering is Starshine ‘violet’ and Starshine ‘Apricot’.  They also grown to 10 inches tall with about a 2 foot spread.  Making them spectacular plants for containers.  They bloom and rebloom from Spring to Fall.

And you have to see the new Minifamous NEO series selection called ‘Vampire’ – not surprisingly it’s blood red!  Another 2017 introduction is ‘Pink Strike’!

Happy Summer Solstice!

You would think that since it is summer in the Northern Hemisphere, the Earth is closest to the Sun right now, but it’s the opposite – the Earth is actually farthest from the Sun during this time of the year.  The longest day and shortest night brings us full blown into summer heat, although we’ve already experienced the heat and humidity!  My herbs, tomatoes and peppers are rejoicing.  And the roses this year….

Carpet roses

Rose ‘Music Box’

The Celts and Slavs celebrated the first day of summer with dancing, so cut loose and do the Happy Dance!

We’re beginning to enjoy some harvests from our vegetable gardens and taking advantage of Farmers Markets all over the state.  How DO they get those veggies so soon?  Well, some have greenhouses, others use what’s called High Hoops [University of MN].  They’re not very practical for most home gardeners but I’m sure thankful for the delightful veggies they produce!

Grilled summer lettuces recipe from Organic Life magazine:

A little char gives greens a complex, steak-like flavor.  For the liveliest salad, choose head lettuces in a variety of colors and textures.

• 5 mixed heads of lettuce (such as romaine, escarole, radicchio, kale and butter) halved or quartered with cores intact
• 1/3 cup olive oil, plus more for brushing
• 1/2 tsp. kosher salt, plus more to taste
• 1/2 tsp. freshly ground black pepper, plus more to taste
• 3 Tbsp. red wine vinegar
• 1 Tbsp. minced shallot
• 1 1/2 tsp. Dijon mustard

Prepare a charcoal or gas grill for indirect grilling or place a grate over a campfire.  Brush lettuces on all sides with oil as needed.  Season with salt and pepper.  Grill, turning frequently, until wilted and lightly charred on all sides, 2 to 10 minutes, depending on lettuce and heat.  Transer to a serving plate.

In a small, lidded jar, add the ingredients for the dressing, shake well and drizzle over lettuces.

Weeding not your bag?  Me either!  Although occasionally I find it cathartic, I prefer not to HAVE to do it.  How about some weed-blocking plants!  They pack a punch to knock out weeds, but they are invasive.

The samurai of weed blockers do so by shading weed seeds and not allowing them to germinate.  Here are just a few to get you started:

Lady’s Mantle is a great part shade plant and grows to about 18 inches tall.  Try a variety called ‘Thriller’.

Moss phlox ‘Emerald Blue’

Creeping phlox

This pretty groundcover, moss phlox,  likes full sun and is zone 2 hardy!  wow…

Liriope handles nearly any condition.  Plant in part shade in zone 4.

Creeping Jenny is another weed blocker that appreciates sun but will do fine in part shade. The caveat to this plant is that it can get brown edges.  I just cut it back then.

Creeping Jenny

Sedum can be grown in sun to part shade and offers several cultivars.  I have green with red stems and little yellow flowers and also ‘red dragon’

a couple of sedum varieties and creeping jenny

Snow-on-the-Mountain is a great weed blocker for shade.  This stuff can’t hardly be killed.

I enjoy an occasional weeding session, it’s cathartic.

Okay, he’s actually trying to pull a beet out of the ground but you catch my drift

Annual weeds tend to be easier to pull out, it’s the perennial weeds that drive us crazy!  Those roots that break off in the soil will spread and make more!  In the vegetable garden, it’s tougher because you really don’t want this stuff on your food!!!!  I have Milkweed in my vegetable garden that I don’t want to get rid of as I’m hoping to host some Monarch butterflies!

This was taken before I planted this year – the milkweed is in the middle of my veggie garden!

When the weeds start winning, it’s time to break out the heavy artillery, HOWEVER, please use extreme caution and don’t over use.  [personally I don’t use Roundup or anything with glyphosate] And never use chemicals in your VEGETABLE garden unless they specifically say it’s okay….  I am battling to much milkweed but only hand pull.

Choose a windless day, using a cheap sponge paint brush and a cool whip container of weed killer, paint the weeds leaves on both sides.  This will send the chemical through the plant into the root system killing the weed.

The other method is to use a gallon milk jug with the top and bottom cut out, place the jug over the offending weed and spray it with weed killer.

Major thing to remember – SAFETY first!  Use protective gear as indicated on the package and be very careful not to get the chemical on any plant you want to keep!

Click below to listen to my Garden Bite radio show:  Little reminders

Sometimes we forget that not everyone knows how to do things we’ve done for years.  In that spirit, today is about Little Reminders.

When planting containers:

• Right Plant, Right Place (I know we talked about this but always a good thing to reinforce)
• In container planting, mix perlite with your potting soil to lighten it and allow better drainage
• plant your purchase at the level it was growing in (most of the time)
• remember to allow enough room to water your plant, don’t plant it at the top of the container – allow about 1 to 2 inches from the top
• place your plants and tamp down, if you need more soil, add it and tamp again being sure not to bury the plant
• In hot weather you’ll need to water those plants twice a day

When planting perennials:

• dig your hole at least twice as wide as the plant’s temporary pot – the reason being to allow the roots an easier time growing into the soil.  IF you’ve already prepared the planting bed (adding compost) then the soil should be fluffy enough that you don’t have to dig a hole that big, just enough for the plant to fit in!
• plant your transplant at the same level it was in the pot it came in (unless there’s more soil on TOP of the container it’s in)
• be sure to loosen the plant gently out of it’s container – place it on it’s side, tap the sides, make sure any roots coming out the bottom aren’t going to “catch” and pull the plant out
• make sure you water that dry plant before filling the hole with soil
• tamp down the soil with your hand or a tool, gently.  This takes out air pockets that may make your plant sink too deep
• if the roots of the plant are wound around itself, then unwind them and loosen them up.  This will allow the roots to spread more easily.  You don’t want them growing around rather than out, this will girdle the plant and potentially kill it
• When placing your perennials, keep in mind their mature size and space accordingly
• And be sure to keep a close eye on your new plantings for the first month in particular
• bareroot plants should be soaked 24 hours before planting

Most dogs love the wind in their fur, motorcyclists like the wind in their hair, bugs in their teeth.  I see lots of people driving down the road with new trees and shrubs hanging out of their trunks, trailers and truck beds.  Branches bent beyond normal as they’re whisked away in highway winds.  Leaves being beaten to a pulp.  There are so many reasons this is not good.

Let’s say the leaves actually survive the trip, that wind has just sucked out any moisture they may have had from the nursery and they’re now in a weakened state and will be even more stressed when they arrive in their new home.

Ahhh, this would be a NO

My plant sale purchases above fit nicely in my old CRV but I also have plastic available to keep it at least somewhat clean!  Any larger shrubs, I’ll lay down.  If I can’t fit them in my vehicle, I’ll make sure they’re wrapped for transport.

Tips to live by:

First, always buy healthy plants to begin with.  Look it over carefully.  Check for yellowed or spotted leaves, dead branches and overall health.

Smaller purchases may take longer to grow to the size you want but they will adjust to their new home much quicker, have a better chance of survival and are usually cheaper.

You’ve selected the best of the best, now you need to wrap it.  Some local nurseries are very good about wrapping twine around new trees.  I would suggest going further.  If you have some old sheets or tarp, bring them with you.

Wrap each purchase with a layer of sheet or the tarp, secure with twine and make sure the trunk of the tree or shrub isn’t going to rub on anything when you go over bumps.  If you can’t plant right away, then store your new trees or shrubs in a shaded area and water enough to keep the roots and soil moist till you can get them planted.

Click below to listen to my Garden Bite radio show:  Plant sale mania

It’s plant sale time at many area garden centers.  Oh, those glorious buys you can get!  Just remember, they’re only a deal if they grow.  Make sure you’re getting healthy stock.  If possible, loosen the plant and hold it by the stem very close to the soil line, pull it out of the pot and look at the roots.  Check that they’re not yellow or mushy.  The last thing you want is root rot!

Check over the leaves and stems, look for any insect damage.  If a few leaves are yellowed, well, I wouldn’t get too picky, after all you are getting a deal but you don’t want to see a LOT of the leaves that way.  Make the garden center your last stop of the day, you don’t want to leave them in the hot trunk of your car for long or they’ll be toast.   Get your goodies home and plant asap.  This is the time of year when new plantings need extra t-l-c.  With warm, dry conditions these plants take longer to establish.

When planting now, you need to really give your new beauties a good start.  That does NOT mean fertilizer.  It means planting them at the right depth, adding a lot of compost to keep the soil fluffy and allow the roots an easy time to grow into their new home.  Add an inch or 2 of mulch for water retention.  Also, WATER WATER WATER.  I don’t mean drown them, but do make sure they’re watered well (about an inch or so a week) until the ground freezes!  Some nurseries will tell you exactly how much to water your new plants.  Follow their directions!

Ninebark ‘Amber Jubilee’

AFTER the ground freezes, then add another 3 inches or so of mulch.  This will help to stabilize the ground temperature.  Heaving can be a problem.  When that happens, sometimes the plant can be pushed up out of the ground enough to expose the roots, NOT something you want!

ps  check over plants carefully before buying them.  You may not be paying a lot, but you still want good product.
