Foliar feeding is a technique of feeding plants by applying liquid fertilizer directly to the leaves. [1] Plants are able to absorb essential elements through their leaves. [ 2 ] The absorption takes place through their stomata and also through their epidermis .
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]
Cannas are largely free of pests. However, in the eastern and southern United States, plants sometimes fall victim to the canna leaf roller moth, with the resultant leaf damage, while not being fatal to the plant, can be most distressing to a keen gardener's eye. [5]
The seed from selected plants is bulked for the next generation. This method is used to improve the overall population by positive or negative mass selection. Mass selection is only applied to a limited degree in self-fertilizing plants and is an effective method for the improvement of landraces.
Plants require specific temperatures to grow and develop properly. Temperature can be controlled through a variety of methods. Covering plants with plastic in the form of cones called hot caps, or tunnels, can help to manipulate the surrounding temperature. Mulching is also an effective method to protect outdoor plants from frost during the winter.
Plant domestication is seen as the birth of agriculture. However, it is arguably proceeded by a very long history of gardening wild plants. While the 12,000 year-old date is the commonly accepted timeline describing plant domestication, there is now evidence from the Ohalo II hunter-gatherer site showing earlier signs of disturbing the soil and cultivation of pre-domesticated crop species.

Cucumbers were planted in wheeled carts which were put in the sun daily, then taken inside to keep them warm at night.
