Annual herbs can be planted in the garden in spring. Annual herbs are also ideal for containers. Pots can be brought indoors for the winter and placed near a sunny window for harvesting through the cold months. Return the plants outdoors in the spring when the danger of frost is past, or simply replace with fresh plants.
The chilling requirement of a fruit is the minimum period of cold weather after which a fruit-bearing tree will blossom.It is often expressed in chill hours, which can be calculated in different ways, all of which essentially involve adding up the total amount of time in a winter spent at certain temperatures.
Hardiness of plants is defined by their native extent's geographic location: longitude, latitude and elevation. These attributes are often simplified to a hardiness zone. In temperate latitudes, the term most often describes resistance to cold, or "cold-hardiness", and is generally measured by the lowest temperature a plant can withstand.
Timelapse of growing basil Desiccated basil showing seed dispersal. Basil is an annual, or sometimes perennial, herb.Depending on the variety, plants can reach heights of between 30 and 150 centimetres (1 and 5 feet). [6]
As a tropical plant, Thai basil is hardy only in very warm climates where there is no chance of frost. It is generally hardy to USDA plant hardiness zone 10. Thai basil, which can be grown from seed or cuttings, requires fertile, well-draining soil with a pH ranging from 6.5 to 7.5 and 6 to 8 hours of full sunlight per day.
It has been adapted by and to other countries (such as Canada) in various forms. A plant may be described as "hardy to zone 10": this means that the plant can withstand a minimum temperature of 30 to 40 °F (−1.1 to 4.4 °C). Unless otherwise specified, in American contexts "hardiness zone" or simply "zone" usually refers to the USDA scale.
Lemon basil requires the same care as other basil varieties. It is a tropical plant, that should be in a spot receiving at least six hours of direct sunlight a day.It is actually quite hardy and can sometimes grow continuously given only water, but the flavor will be at risk if not given any fertilizer, chemical or organic.
DIF is a greenhouse technique involving temperature control for the purpose of controlling plant internode length and thus elongation rates. DIF's effectiveness has led to a reduction in the need and use of chemical plant growth regulators. Although many common greenhouse plants do react strongly to -DIF, there are some plants which show little ...
