Pruning is required to maintain the shape and size of the plants as they can quickly become unruly and top heavy. Pruning also enables access to the plant which assists harvesting. Care should be taken to dispose of the cuttings as they have the potential to become weeds.
Refer to the Pitaya Growing Note – FG1 for more information.
Step 1 – Before: Pruning should occur after the last harvest in May-June.
Step 2 – Clean main stem: Branches growing up the main stem must be removed.
Step 3 – Remove old growth: Selectively remove the older branches from underneath.
Step 4 – Cut back clean: Cut branches back to the original stem.
Step 5 – Set canopy size: Keep at the most 50 main branches leaving only 1-2 sub-branches per main branch.
Step 6 – After: Pruning is needed to maintain fruit production and size ready for September-October flowering.
Varieties: There are no varieties in the proper sense, but there are many clones which can differ in the stem type, colour, fruit shape, skin thickness and scale expression. There are however two different species, H. undatus which has white flesh and H. polyrhizus which has red flesh. There are also several other fruiting cactus genera that are called ‘pitaya’ one of these is Selenicereus megalanthus which has smaller fruit with yellow skin, white flesh and clusters of spines on the fruit that brush off when ripe.
