Question

What fertilizer or used for vegetative propagation

Answer 1

Unrooted cuttings (URCs) require higher tissue nutrient levels than finished plant material because tissue nutrient concentrations often drop from just after sticking until roots begin to form. If the cuttings contain a high level of nutrients (relative to finished plant material), then this drop will not cause a problem because the tissue levels never reach a minimum critical level that affects growth, if fertilizer is supplied throughout the rooting cycle (Figure 2). However, if the nutrient levels in the URC are low to begin with, then this drop can cause nutrient levels to drop below the critical level, often causing the appearance of nutrient deficiencies, slow or non-uniform rooting, or greater susceptibility to diseases.
