HEAT? DROUGHT? NO PROBLEM.

Physiological Workaround

Portulaca is a genus that gives us a vegetable, a weed, and a flower. All flourish undaunted by heat or drought, a comforting thought as I drag the hose or lug a watering can around to keep beebalm, an Edelweiss grapevine, and some marigolds and zinnias — all planted within the last couple of weeks — alive.

Portulaca employ a special trick for dealing with hot, dry weather, which presents most plants with a conundrum. On the one hand, should a plant open the pores of its leaves to let  water escape to cool the plant, as well as take in carbon dioxide which, along with sunlight, is needed for photosynthesis. On the other hand, the soil might not be sufficiently moist or the pores might end up jettisoning water faster than roots can drink it in, in which case closing the pores would be the ticket.

Portulaca gets around this …

UNPERMACULTURE

Accusations,  (Mostly) not True

I’ve understandably been accused of being a “permie,” that is, of practicing permaculture.    (In the words of permaculture founder, Bill Mollison, “Permaculture is about designing sustainable human settlements. It is a philosophy and an approach to land use which weaves together microclimate, annual and perennial plants, animals, soils, water management, and human needs into intricately connected, productive communities.” In the words of www.dictionary.com, permaculture is “a system of cultivation intended to maintain permanent agriculture or horticulture by relying on renewable resources and a self-sustaining ecosystem.”)    Walk around my farmden and, yes, you’ll come upon Nanking cherry bushes where forsythia bushes once lined the driveway, an American persimmon tree where a lilac bush once stood, and other edible plants used also for landscaping. In the vegetable garden, I preserve soil integrity by never tilling it, and, in the south field, blackcurrant bushes make use of the space beneath …

HOT DAYS, BUT PREPARING FOR FALL

Ignoring My Gut

Like other parents, I don’t hold back preparing for fall just because of hot, sun-drenched sunny days. But my preparations don’t entail trips to the store for notebooks, pencils, rulers, and other school gear. My daughter is old enough to gear up for herself. Instead, I’m preparing for a garden that becomes lush with ”cool weather” vegetables just as tomatoes, peppers, okra, and other warm weather vegetables are fading OUT.    Much of gardening entails NOT going with your gut. If I went with my gut, I’d be planting more tomatoes and sweet corn and, perhaps, if I was really going with my gut, even banana trees on today’s ninety plus degree, bright, sunny, humid day.

Sprouting seedlings, planting seeds, and transplants

    Although tomatoes, peppers, and cucumbers presently have more appeal, fall vegetables will have their day. I have to remind myself how a lowering sun and …
