1. A fall season like no other (except last fall?). So that’s TWO wet, cold, snowy fall seasons in a row- what is going on?

    November 25, 2019 by MAX

    Below is a copy of an older blog from a year ago- when we had several snow events, loads of wet days, and very cold temps. Sounds like a broken record-? Fast forward to this November: already have had 2 snow events (one on Halloween), with unreal cold in late October……4 above zero in the far western suburbs.

    Bitternut hickory (Carya) foliage, like so many other species-were still in leaf when the snows came, followed by single digit temps. Many trees and shrubs did not lose leaves, as they froze on the branches. Long term consequences of 2 years of freakish cold so early? TBD.

    With dramatically wetter weather throughout the Great lakes region (ie: record high levels on Lake Michigan), there are also those wild temperature swings (as in early cold spells, polar vortexes etc) and early snowstorms. Much seems to be due to unusual jet streams, and climate change. And as these crazy patterns continue, we see more changes (and damage) to our tree canopy and to the natural communities ( discordant insect vs bird migrations, continually wet soils etc). On the traditional landscape plant list – the damage from early 2019 record low temps (polar vortex) killed off many plant types we have come to love (and perhaps overplant) for decades: boxwood, ornamental Asian maples, Chinese dogwood, and the list goes on…..

    Conclusion: as the climate warms, we had come to accept the idea of planting species accustom to southern and warmer climes. No longer. Conjecture has it that the phenomenon known as the ‘polar vortex’ will continue in future winter months of the upper Midwest, thus knocking back, or killing off southern species. So what to do?

    Perhaps sticking to native species such as *oak, hickory and other hardy northern species- the damage may be lessened? Continuing to plant tender species (Acer palm., Cornus kousa, buxus sp. etc) may be an unwise long- term plan.

    * Plant oaks- help sequester carbon, cool and cleanse the air, and slow the heavier rain loads. Oaks also support more species than any other tree species. Contact us to discuss what species best suits your situation.

  2. Witch-hazel ‘Jelena’ (Hammemalis med.), unusual, very early to bloom, so interesting!

    The earliest of any blooming plant in this West Chicago garden. Click on pic to  enlarge.

    A very cool plant- you will not find any other witch-hazel or other species of plant that blooms earlier, none! Fragrant too. And the bonus is that fabulous red/burgundy fall color!  Vase shaped habit, likes a bit of shade, growing to 8′ x 8′. One of Ed’s favorites!

     

     


  3. Oakbrook Landscape Projects: patio and water feature (pondless) phases seen below

    A water feature has all the effects of a pond, but without the open water. Attracts wildlife as well.

     

    Oakbrook landscaping pond, patios, stone walks

    Will need a year or two to fill in. Using low grow native dropseed grasses, juniper, geranium, thyme, Asters

    Natural stone added to this waterfall, pondless water featrure. Sedges (Carex) are a good choice, esp. if the area is moist.
