    Greetings!
    Thank you for your posts on aphids. Meadow rue thrives in our northern grotto patio in Anchorage,
    Alaska. I have tried everything, smashing, spraying with water, homemade soap mixtures, Neem oil soap. Each spring the pesky aphids return. This year they are also on the columbine surrounding some of the Thalictrum. I will look for nettles and try that with my soap solution. Please keep posting, I hope to be surprised one year when they disappear.

    1. Hi Andee, funny - I just sprayed aphids off of our roses at the back this evening. I seem to have avoided getting them on the Meadow Rue this year. So far, anyway. We mulched the base of the plant last fall with Hemlock shredded bark. It's a finer grade of mulch that works well with perennials. I think it has boosted the Meadow Rue's ability to avoid the aphid attack. Perhaps try a type of mulch if you can. Cheers!

  2. Hi Heidi:

    On your website you have a picture of a cornflower with a tiny black and white inch worm. I have those on my coneflowers too! Do you know what they are? I have been searching the internet and have had no luck so far.

    Thanks,
    Renu

    1. Hi Renu, Good eye! Yes, that summer we had several of our trees with the Fall Cankerworm (Inch Worm) Alsophila pometaria. Several of them dangled down with their silken threads and landed on our Echinacea and Hostas below. I watched it gingerly crawl off the flower and dangle down to the next set of leaves. I didn't notice any feeding on the Echinacea.

      This year in Toronto, we have 'cankerworms' in huge proportions. The mild winter and wet spring has unearthed a huge infestation. Our trees are chewed up pretty bad.

      Cheers! H :)

  3. Thank you for solving the mystery! The winter was mild here too in NYC, so that would explain it. While the echinacea are not near any trees, they probably were at the nursery where I purchased them.

  4. Hello,
    My Nanna has just been moved to a nursing home and she has the loveliest little Holly bush in her garden, of course now the ground is fully frozen in Hamilton and the house is no longer hers as of January. Any suggestions? I would love to save it, to keep it in the family she has pruned it perfectly.

  5. Oh dear, I feel for you and your Nanna! I can't say I've ever transplanted or uprooted a Holly Bush this late in December. If the ground is frozen solid, well it would be rather tricky trying to dig it up. I wouldn't advise trying to do it this late, now that winter is here to stay. I too wished to uproot many shrubs and perennials from my parents' home, but couldn't. I do however, drive by occasionally and become thankful in seeing the same shrubs live on despite the new owners endeavours.

    Perhaps ask the new homeowners in early summer, to see if you can take some cuttings to root.

    Or take some cuttings now and press them for memories sake.

    Take lots of pictures for memories sake.

  6. We have about 15 euonymus shrubs of all sizes and ages that seem to have been hit by something this 'spring'. Many of them have dropped a lot of leaves, some have sort of rusty coloured leaved and some are faded. A few of them now have what look like healthy new growth. Could all of these have been attacked in one season by scale or is this some sort of winter kill? Thank you!

    1. If you see why crusty rice looking debris on the stems of your euonymus, then you might have scale insects. But generally, when we have a harsh winter in the Toronto area, because euonymus are broadleaf evergreens, their leaves can become brown, faded, papery and drop. Not to worry, euonymus are tough and will defoliate with lush new growth. Be patient. Water the shrubs during drought times to help the plants re-flush foliage during the hot summer months. Check your euonymus stems for scale. Check the top tab of insects and disease where you can find a post on Euonymus scale. Cheers

  7. Hello! We have boxwood shrubs that we’ve had for about five years. We recently noticed they are making “buzzing” sounds. I read somewhere it could be an infestation of some sort. We have no clue what we are doing, if it’s an infestation how can we best treat it? Or do we rip them out? Thank you in advance!

    1. Sounds like you have boxwood leaf minor or boxwood psylids. I've heard the buzzing sound with both. Specifically with the leaf miner. Here is a post I made on how to treat it: http://www.heidihorticulture.com/2013/05/boxwood-leaf-miner-monarthropalpus.html
