Planting and care
Planting

Like all citrus varieties Wheeny grapefruit do best when planted in well-drained soil that gets plenty of sunlight and is sheltered from strong winds.  See Planting Citrus Trees for planting information.

fertilising

Citrus trees are heavy feeders, requiring lots of rich organic composted matter to produce a tree ladened with juicy fruit.  They also need a fertiliser high in nitrogen with fertiliser additives that contain all the nutrients and trace elements needed for strong growth.    Suitable fertilisers include:- 

  • CHICKEN MANURE
    Very high in nitrogen.

  • DYNAMIC LIFTER
    Pelletised chicken manure that is high in nitrogen.

  • BLACK MARVEL FRUIT & CITRUS FOOD
    Apply as directed by the instructions on the package.

  • UREA
    Soluble nitrogen.

  • EPSOM SALTS  (MAGNESIUM SULPHATE)
    Australian soils are low in Magnesium sulphate and citrus trees need it to thrive. 

Fertilise every four to six weeks during the growing season or as directed by the instructions on fertilser bags.

Pruning

Regular pruning of citrus trees will yield more and bigger fruit, prevent damaged and diseased wood, and help maintain the size of and shape the trees.  

  • PRUNE AFTER THE RISK OF A HEAVY FROST HAS PASSED IN EARLY SPRING
    A second pruning can be done at the end of  Summer or early autumn.

  • REMOVE EXCESSIVE SHOOTS AND DEAD OR SAGGING BRANCHES

  • PRUNE THE OUTER BRANCHES TO THE HEIGHT AND SHAPE THAT  YOU WANT
    But no more than 20% of the trees foliage should be pruned at any one time.  The outer small branches can be removed using garden sheers or a hedge trimmer.
Pest control

The main pests of all citrus varieties are mealy bugs, (small, white, furry looking insects that are sticky to touch), scale and aphids, all of which are sap sucking insects. The sugary substance they excrete discolours the leaves with a black sooty mould, which impedes the ability of the leaves to photosynthesize.  Spraying with white oil and pyrethrum will usually control these sap sucking insects, though you will usually have to spray two or three times.

Another citrus pest is the citrus gall wasp. This insect lays its eggs in the branch, which swells so the hatching insect can get food. To control gall wasp, prune the gall out and get rid of it before September, when the adult hatches.

Queensland fruit fly is also a serious pest for citrus trees in areas where fruit flies are active. 

Personal experiences

My Tangelo tree produces large juicy fruit that is suitable for both eating and juicing, it’s my best juicing citrus tree, sweeter than the fruit my Washington Navel orange trees produce and easier to squeeze as the skins are thinner. The fruit stays on the tree from July through to the end of October, which gives us a ready supply of tangelos for an extended period of time.  The tree suffers very little frost damage even though the night temperature in winter in Ballarat can drop to as low as -5 °C.

My Tangelo tree.  It has consistently produced a heavy crop of fruit that sits on the tree from July through to the end of October.  

The fruit my Tangelo produces is similar to a mandarin but juicier, making it ideal for both eating and juicing.
