THE SUBURBAN LOT

  • IT’S TOO HOT…AND DRY

    August 2015

    thermomFollowing record breaking June rainfalls for New Jersey, the recent high temperatures coupled with weeks of no precipitation make this summer one of the hottest and driest on record. “Wilting, withering” and “mercury popping” is how one writer aptly describes growing conditions this year – and I couldn’t say it better.

With little rain and continuous high temperatures, plants are taking a beating, in some cases failing to reach full potential for size and flowering. Even many ‘full sun’ selections in my nursery look stressed, and have been relocated to the shade house to recover and prevent further damage.

    IMG_8337Climate change, man-made or otherwise, is a reality that affects all life. Over the last twenty years I have observed dramatic shifts in what is considered ‘winter hardy’ in our zone 6. Now perhaps I have to reconsider what is ‘summer hardy’? Extremes on either end of the spectrum have made specifying and providing warranties for the landscape a challenging task.

    thThe best bet for summer survival is to keep plants as hydrated as possible. Lawns and beds may need heavier and longer watering in long runs of high temperatures where no rainfall is predicted. Of course, check for any current watering restrictions.  For lawns, ask your contractor to keep the blades set high to 3 or 3 ½”….a scalped lawn in dry heat is fast to burn. A 2” to 3” layer of mulch is also crucial to lock moisture in and to maintain lower soil temperatures.

    thPlants should also be carefully sited to make sure they are in the best location for their sun tolerance. Some items may need to be moved. Drought resistant varieties that prefer dry heat and little to no irrigation (lavender, catmint, coreopsis, artemisia) will likely increase in their landscape value as time goes on. I’ll be taking this into consideration as I plan this winter for next year’s installations.
