Making new plants from old, or sex in the greenhouse--call it what you will, propagating your own plants is easy, fun and very rewarding. Seeds: Although any plant that flowers can be started from seed--and that includes virtually every plant in the kingdom with the exception of ferns, which do not flower and are propagated from spores--this method is a bit more challenging than methods such as rooting cuttings or runners. Sow the seeds about half-an-inch deep and an inch apart, place the tray in a bright, warm location, and make sure the soil never completely dries out. When seedlings appear, which should be within about three weeks, separate the larger, stronger seedlings and put them into individual 3-inch-diameter pots in a mixture of half potting mix and half peat moss.

Sex among the tomato plants in a greenhouse! An amazing technique to combat this pest is now being deployed by professional tomato growers. By flooding the greenhouse with this irresistible pong from the point of view of the male South American Tomato Leafminers the males become so confused that they never find a female to mate with. No mating means no next generation of leafminers and so the tomato crop escapes damage from the pest and both the grower and the consumer are happy. Almost all tomatoes in Britain are grown in heated glasshouses. They are produced in our natural season and harvested between March and November.
'I just want to survive:' Greenhouses struggling with economic reality of COVID-19
The Canadian Press Staff. The doors of Golden Acre Home and Garden in Calgary are allowed to be open as an essential service in Alberta, but there are ample warnings about social distancing. A steady stream of customers, many of them wearing face masks, walk through the store even though spring bedding plants aren't ready and the selection of seeds and flowers is somewhat limited. Zannis said having an online presence puts his greenhouse on less shaky ground than many others. The business has sent products to as far away as Nunavut and Nova Scotia in recent years but will be focusing primarily on the Calgary market now.
Sex-related differences in reproductive effort can lead to differences in vegetative growth and stress tolerance. However, do all dioecious plants show sex-related differences in stress tolerance? To what extent can the environmental context and modularity mask sex-related differences in stress tolerance? Finally, to what extent can physiological measurements help us understand secondary sexual dimorphism? This opinion paper aims to answer these three basic questions with special emphasis on developments in research in this area over the last decade.
