Lemon balm seeds require light and a minimum temperature of 20 °C (68 °F) to germinate. The plant grows in clumps and spreads vegetatively (a new plant growing from a fragment of its parent), as well as by seed. In mild temperate zones, the plant stems die off at the start of the winter, but shoot up again in spring. Lemon balm grows vigorously.

Winter wheat is grown as a cash crop or a cover crop.Optimal growing conditions for winter wheat include high-drainage soil with medium texture. Mid-quality soil nutrient content is best for winter wheat, with an appropriate supply of nitrogen being critical for the wheat to be able to establish itself in time before winter dormancy.
Seeds of many trees, shrubs and perennials require these conditions before germination will ensue. [3] In the wild, seed dormancy is usually overcome by the seed spending time in the ground through a winter period and having its hard seed coat softened by frost and weathering action. By doing so the seed is undergoing a natural form of "cold ...
In France, the recommendation for the first nitrogen application on wheat is 6 weeks before Z30, with the second application on Z30. Wheat growth regulators are typically applied at Z30. Disease control is most critical in the stem extension and heading stage (Z31, Z32, Z35), in particular as soon as the flag leaf is out (Z37).
Winter wheat at the end of March. Winter cereals, also called winter grains, fall cereals, fall grains, or autumn-sown grains, are biennial cereal crops sown in the autumn.They germinate before winter comes, may partially grow during mild winters or simply persevere under a sufficiently thick snow cover to continue their life cycle in spring.
Astronomical winter begins on the winter solstice, which is the shortest day of the year when the North Pole is tilted away from the sun. This year that's Saturday, Dec. 21, which will be 5:21 a.m ...
In 1857 an American agriculturist John Hancock Klippart, Secretary of the Ohio Board of Agriculture, reported the importance and effect of winter temperature on the germination of wheat. One of the most significant works was by a German plant physiologist Gustav Gassner who made a detailed discussion in his 1918 paper.
