The old 2012 map, seen here, isn't as detailed or regional as the new plant hardiness map, in large part to the 2023 map including data from many more weather stations.
A seed rate of about 100 kg of seed per hectare (2 bushels per acre) is typical, though rates vary considerably depending on crop species, soil conditions, and farmer's preference. Excessive rates can cause the crop to lodge, while too thin a rate will result in poor utilisation of the land, competition with weeds and a reduction in the yield .
Plant density is defined as the number of plants present per unit area of ground. In nature, plant densities can be especially high when seeds present in a seed bank germinate after winter, or in a forest understory after a tree fall opens a gap in the canopy.
Western US – One of the best spring forage sources for honeybees. Blooms 45–60 days and continuously produces nectar throughout the day. Can be seeded several times per year. Prefers 3 ft of topsoil. 180–1,500 pounds honey per acre, depending on soil quality and depth; 300–1000 pounds of pollen. [9] G, H Plantain: Plantago Major ...
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.
For example, a single tomato plant takes a full square, as might large herbs such as oregano or basil, while lettuce plants would be planted 4 per square, and up to 16 per square of plants such as radish or carrots. Tall-growing crops are planted or trellised on the north side of the bed (in the Northern Hemisphere) to avoid shading shorter plants.
