Emerald Ash Borer: What to Look For

How to

While there are several signs of the presence of Emerald Ash Borer, you’ll be surprised at what people first notice.  Woodpecker holes. Apparently ash borer larvae are woodpecker candy, so if you see an ash tree that’s getting a real going over by woodpeckers, you may want to look further.

Other signs of an infestation include die-back at the top of a tree, especially if several ash are planted together and they all look bad; D-shaped exit holes in bark; and sprouts of leaves and branches from the base of the tree.

Of course, the first thing to do when scouting for this pest is to make sure you are looking at an ash tree.  I put this guide up a couple of years ago, which might be helpful in determining if the tree you have is indeed an ash.

    Great tips and things to look for in our ash trees. It is truly a shame the ash will be the next American Elm, but maybe there will be an answer for both trees sometime in the future. We can only hope.

It’s National Gardening Day! I’m not much for It’s National Gardening Day! I’m not much for special days (sorry, siblings, I missed that one last week) but any excuse to post a picture of a gorgeous peony, I’ll take! 

Peonies are a huge part of Minnesota’s horticultural heritage. They aren’t native but our cold climate is perfect for peonies. They’ve been hybridized in Minnesota for over 150 years, and the state still has several peony breeders based here. If you ever get a chance to go to a peony open day in June, jump on it. Seeing rows and rows of peonies all blooming at once is a northern gardener’s joy. 

Peonies will last forever, too. Plant one in the right place and it will outlive you by decades. What’s your favorite plant?

This week’s podcast and blog post are about grow This week’s podcast and blog post are about growing summer bulbs. I grow lilies in containers, 1) because they look great and 2) because the rabbits 🐇 can’t get them as easily there. Growing bulbs in containers means you can move them around the garden for extra color where you need it. 

Bulbs aren’t that tricky to grow, though you will have to pull dahlias, gladiolus and canna lilies for the winter. Lilies can stay in the ground. This winter, I left some in their pots and held  them in the unheated garage. They survived and are already putting up foliage. 

Check the 🔗 in bio for links to my interview with Mike Heger as well as the blog post on growing bulbs in containers.

In bloom at the big box store: Columbine! These lo In bloom at the big box store: Columbine! These look pretty but most of the in ground columbines are just greening up in Minnesota. That’s one thing to remember when shopping for perennial plants now. If it’s in bloom, it’s a spring plant and will probably be green all summer. Nothing wrong with lots of spring bloom in the garden, but plan for the whole season by picking things that bloom in July, August, even the fall, too.

Uff da! This seems really early for daffodils 🌼 Uff da! This seems really early for daffodils 🌼 in Minnesota. Last year, I posted my first daffodil photo on April 12, and it was in snow ❄️! No snow this year, and this tracks with the info I heard earlier this week that we are 10 to 14 days ahead of schedule. I’m enjoying the warmth but can’t shake the memory of 2019’s mid-April blizzard. The joys of cold climate gardening!

Fun news 🗞! I have an essay in the upcoming iss Fun news 🗞! I have an essay in the upcoming issue of Gardening for Health, a special interest publication of Better Homes & Gardens.

Wondering what winter burn looks like on shrubs? C Wondering what winter burn looks like on shrubs? Check it out. I’ve got three of these dwarf Alberta spruce. This is the worst case. One has no burn, the third just a bit. This one faces south so it gets the most sun and wind. After it starts growing this spring, I’ll trim off the burn. May need some wrapping next winter.

My conversation with Amy from @milkweed.and.daisie My conversation with Amy from @milkweed.and.daisies on the @growitmn podcast got me thinking about annuals that are easy to grow from seed. There are a lot! She grows some I haven’t had in years, like hollyhocks and snapdragons, plus plenty of my favorites. Seven really easy options are listed in a new blog post (🔗 is bio) on the My Northern Garden blog. Cosmos, zinnia and sunflowers may be the easiest of  all. 

The sunflower 🌻 pictured is The Joker. The zinnia photo is one I took of the zinnia beds at the @ballseedgardens I’m not sure about the cosmos, which are from a tour garden. 

Plant any of these annuals in sun and let them grow. Suggestions for annuals to try this year? I’d love to hear them!

Crocus so soon! I was taking apart the holiday pot Crocus so soon! I was taking apart the holiday pot and noticed three crocus blooms in my south-facing front bed. This is a full week earlier than last year, and that felt early to me. They’ll probably get snowed on come Monday. 🌨🌸
