Dragon fruit

Lime, Dolomite, NPK, Dynamic Lifter

Many of the fruiting cacti grow naturally in areas with high minerals, lime and decaying organic matter. A balanced NPK fertiliser, organic fertiliser, lime, and foliar fertiliser during fruit growth are required by H. undatus. Fertiliser is included in the planting hole and then applied after the first month. Fertiliser can be applied as granules or through the irrigation. Nitrogen is required during vegetative growth, but is normally reduced during the resting and pre-flowering stages. A suggested fertiliser program of NPK, dolomite, and dynamic lifter can be applied on alternate months at a rate of 100 g/plant.

Poultry Manure, Boron, Zinc, Potassium

Organic fertilisers such as poultry manure have the benefit of improving the physical and biological characteristics of the soil, as well as supplying some nutrients. However, it is important that these materials are properly composted for at least three months before use, or applied more than four months before harvesting commences. Do not apply during or near harvesting. This minimises the risk of microbial contamination of nuts on the ground. Also remember that organic fertilisers such as poultry manure are generally lower and more variable in nutrient content than inorganic fertilisers, and are slower in their response. The timing of fertiliser application should be largely based on an interpretation of the soil and leaf analysis results. However, as a general rule, split nitrogen fertiliser requirements into as many applications as practicable throughout the year. Apply the bulk of potassium fertiliser requirements in the spring with the rest spread throughout the year. Apply fertilisers of low solubility, such as phosphorus fertilisers, gypsum or zinc sulphate, before the summer rains to help with incorporation. Where used, apply boron and zinc foliar fertilisers to new growth flushes (boron in spring and zinc in summer).

Used Teabags, Cow Manure, Citrus Fertiliser

Keep these hungry vines weed free, well watered (especially when there’s little rain) and fed from spring to autumn. Use pelletised flower and fruit, a citrus food or a chicken poo fertiliser. Water plants well before adding fertiliser then spread it around the base of the stem and along the area where the roots are growing. After feeding in spring, spread organic mulch such as compost or aged cow manure 2 to 3 centimetres deep. Don’t let it build up against the stem and don’t dig it in as this may encourage suckering.
