Researchers at the University of Delaware found that when a plant has its leaf nicked, it sends out an alert to neighbouring plants, which begin beefing up their defences.

Injured plants can warn their neighbours

That smell of fresh-cut hay may be organic compounds 
from the damaged leaves

A high school student working on a research project at the University of Delaware has discovered that damaged plants can send a warning to their neighbours, which grow larger to compensate. Working in the lab on weekends and during summer breaks, Connor Sweeney cultured an estimated 1,000 arabidopsis plants — also known as mustard weed

Cedars, particularly recently planted trees, should be thoroughly watered before winter 
sets in.

Prepare evergreens for the winter

Evergreens behave differently than deciduous trees so need special care

There are essential tasks to do before winter arrives if our gardens are to be in good shape in the spring. Some of the most important features in many landscapes are the evergreen trees and shrubs that add beauty, not only during the growing season but during the winter months as well. Because evergreens are


Weeds are more obvious when looking at a wheat crop down (r) than looking at it sideways, says Manitoba Department of Agriculture weed specialist Jeanette Gaultier.

Recent rains help crops and weeds

Herbicide-resistant weeds make controlling weeds even harder

Most Manitoba farmers needed the rain, but wet fields have delayed weed spraying, says Manitoba Department of Agriculture weed specialist Jeanette Gaultier. Dry soils delay weed emergence, but the recent rains and warmer weather have triggered germination, creating a green carpet of weeds in some fields. “The crop is going to pop, but so are

Fall a good time for winter annual, perennial weed control

Whether you apply a desiccant or glyphosate depends on the weed and your harvest plans

The swather and the combine are good places from which to spot weed problems and autumn can be a good time to control winter annual and perennial weeds, says Jeanette Gaultier, weed specialist with Manitoba Agriculture, Food and Rural Development. Pre-harvest control hinges on the type and stage of weeds and harvest goals. If a


Assiniboine Community College (ACC) will be establishing a weed identification garden after a donation  from the Manitoba Zero Tillage Research Association (MZTRA) — MZTRA board chair, Brad Lewis (l),  ACC agribusiness instructor, Danielle Tichit.

College to build weed identification garden

Assiniboine Community College looks to establish a weed identification garden to 
house more than 80 of Manitoba’s most common annual and perennial weeds

Southwestern Manitoba will soon be crawling with more weeds but these weeds are for a good cause. Assiniboine Community College is creating a weed identification garden with financial assistance from the defunct Manitoba Zero Tillage Research Association (MZTRA). “The garden will provide students in multiple programs with tangible and real learning opportunities and has the

Nothing standard about a standard

There has been an explosion in the development and marketing of shrubs and trees grown as standards in the last several years. A standard is simply a shrub or tree grown on a single stem and not allowed to get more than a couple of metres high. Usually the top part is grafted to a


Low-maintenance topiary

Watering is all you’ll have to do once this is made I have always loved the look of formal gardens but they are far too much work to maintain, so I designed a pair of “lollypops” to sit in formal urns on either side of my front door. You could call this low-maintenance topiary art.

Gardening in the shade

Many plants will actually thrive in shady areas There are many garden plants that can not only survive, but thrive in the shade, like annuals such as begonia, lobelia and sweet potato and perennials such as astilbe, bleeding heart and hosta. If you have a shady area, here’re some tips:  Shade gardening often means


Ugly Perennials Getting Admiring Looks

In a back corner of the Ian N. Morrison Research Farm is a nursery of what most farmers would consider butt-ugly plants with spindly stems, tiny seeds, and weedy characteristics. But they might just be the salvation of grain farming if the impact of climate change falls hard on the Canadian Prairies. The plots contain

Tall Perennial Ground Covers

Most gardeners are familiar with ground covers that are the “creepy, crawly” type, – those that hug the ground and form a thick mat on the soil surface. There is another category of ground covers, however, that is just as useful in the landscape and the good thing about this group of plants is that
