Nurse grafting is a method of plant propagation that is used for hard-to-root plant material. If a desirable selection cannot be grown from seed (because a seed-grown plant will be genetically different from the parent), it must be propagated asexually in order to be genetically identical to the parent.
The tallest Leyland cypress documented is about 40 m (130 ft) tall and still growing. [18] However, because their roots are relatively shallow, a large leylandii tends to topple over. The shallow root structure also means that it is poorly adapted to areas with hot summers, such as the southern half of the United States.
Care must be taken when planting dwarf or semi-dwarf trees. If such a tree is planted with the graft below the soil, then the scion portion can also grow roots and the tree will still grow to its standard size. Ease of propagation: Because the scion is difficult to propagate vegetatively by other means, such as by cuttings. In this case ...
Because perlite is improves soil draining, plants that prefer damp environments (ferns, mosses, certain tropical plants) should not be potted or planted using perlite in the soil mix, says Mcclure ...
Plant too late and your crops will hit the wall of late spring and summer heat. If cold or rain delays planting at the prescribed time, find another crop that you like almost as much and ...
Different species and varieties react differently to transplanting; for some, it is not recommended. In all cases, avoiding transplant shock—the stress or damage received in the process—is the principal concern. Plants raised in protected conditions usually need a period of acclimatization, known as hardening off (see also frost hardiness).
Most common methods of natural vegetative reproduction involve the development of a new plant from specialized structures of a mature plant. In addition to adventitious roots, roots that arise from plant structures other than the root, such as stems or leaves, modified stems, leaves and roots play an important role in plants' ability to ...
Some plant species, including many trees, do not produce seeds until they reach maturity, which may take many years. Seeds can be difficult to acquire, and some plants do not produce seed at all. Some plants (like certain [4] plants modified using genetic use restriction technology) may produce seed, but not a fertile seed. [5]
