Rumex obtusifolius, commonly known as bitter dock, [2] [3] broad-leaved dock, bluntleaf dock, dock leaf, dockens or butter dock, is a perennial plant in the family Polygonaceae. It is native to Europe, but is found on all temperate continents.
Arctium lappa, commonly called greater burdock, [2] gobō (牛蒡/ゴボウ), [2] edible burdock, [2] lappa, [2] beggar's buttons, [2] thorny burr, or happy major [3] is a Eurasian species of plants in the family Asteraceae, cultivated in gardens for its root used as a vegetable.
Arctium is a genus of biennial plants commonly known as burdock, family Asteraceae. [3] Native to Europe and Asia, several species have been widely introduced worldwide. [4] Burdock's clinging properties, in addition to providing an excellent mechanism for seed dispersal, led to the invention of the hook and loop fastener.
A fertilizer (American English) or fertiliser (British English) is any material of natural or synthetic origin that is applied to soil or to plant tissues to supply plant nutrients. Fertilizers may be distinct from liming materials or other non-nutrient soil amendments. Many sources of fertilizer exist, both natural and industrially produced. [1]
They can reach a length of 20–50 centimetres (7.9–19.7 in) and a width of 10–30 centimetres (3.9–11.8 in). Flowers are purplish red, with a diameter of 0.9–1.2 centimetres (0.35–0.47 in). This species can be distinguished from related ones because the underside of the leaves is covered with white woolly hairs.
Borax, Boric Acid or Solubor can be dissolved in water and sprayed or applied to soil in blended dry fertilizer. Excess boron is toxic to plants so care must be taken to ensure correct application rate and even coverage. [7] While boron may be sprayed on leaves, excess will cause plant damage.
Green manures have been used since ancient times. Farmers could only use organic fertilizers before the invention of chemical nitrogen fertilizer. There is evidence for the Greeks plowing broad beans and faba beans into the soil around 300 B.C. The Romans also used green manures like faba beans and lupines to make their soil more fertile. [3]
It is large and bushy. The leaves are up to 50 cm (20 in) long and ovate. The lower leaves are heart-shaped and have very wavy margins. Leaves are dark green above and woolly below. It grows an extremely deep taproot, up to 30 cm (12 in) into the ground. [7] [8] The plant produces flowers in its second year of growth, from July to October. The ...
