Pomegranate Tips

Print this entry

  • They like to be kept on the dry side as too much water will inhibit fruit set.
     
  • While many sources recommend removing the seeds from a pomegranate by placing half of the fruit cut side down on a work surface and hitting the end with a rolling pin or wooden spoon, we’ve found an even better way that removes every seed without any mess. Cut off the bump on the blossom end and score the outside of the fruit from pole to pole into six sections. Insert your thumbs into the blossom end and pull the fruit apart in sections. Submerge the sections in a bowl of cold water and then bend the rind backward to release the seeds. Pull out any stragglers and let the seeds sink to the bottom of the bowl. Discard the rind and any bits of membrane that float to the surface and drain the seeds in a colander. The seeds can be refrigerated in an airtight container for up to five days.  Ref:  Cooks Illustrated
     
  • Check the flowers and help pollination. If the flower parts are perfect then maybe too much water and vegetative growth caused flower drop. Ants also like to eat part of the flowers so apply a band with a sticky substance to the trunk.
     
  • To produce big fruit, the key is to pollinate them very well. With hand pollination, adequate irrigation, right fertilization and fruit thinning, with the right variety, you can grow bigger fruits.
     
  • Air layering is carried out in the month of May/June. (Nov/Dec here in Australia). In this method a 1-2 year old, healthy, vigorous, mature shoot of 45-60 cm in length and pencil thickness is selected. A circular strip of bark about 3 cm wide just below a bud is completely removed from the selected shoot. Rooting hormones like IBA & NAA 50mg each in Lanoline paste are applied over this portion. Moist sphagnum moss is packed around this portion and tied with polyethylene sheet to prevent the loss of moisture. Application of such hormones promotes early rooting. Light brown roots are visible through the polythene wrap in the month of July-August. The rooted shoot is slowly detached by giving 2-3 successive cuts over a period of week before finally detaching from the parent plant. The polythene sheet is removed before planting them in pots. They are planted in pots and kept in nursery under shade. Top of the shoot is cut back to maintain a proper ratio of leaves:roots. The grafts can be transplanted in the field in the month of Sept/October (March/April in Aust).   Ref:  http://expertsystm.wixsite.com/pomegranate/propogation.
  • Disorder – Internal breakdown: Normal peel with discoloured arils
    Symptoms – The apparently healthy looking fruits when cut open reveal discoloured mushy arils. The arils become soft, light creamy-brown to dark blackish-brown and unfit for consumption.
    Causes – Boron deficiency, calcium and potash deficiency indirectly contribute in cracking. However, improper irrigation is the major cause.
    Control – Give proper irrigation to maintain proper humidity.
    The fruits should be harvested as soon as they mature.
    Management strategies used for other disorders may also help in reducing the problem.
  • PMG Agriculture was growing 120,000 Pomegranates at Bormabil North, Parkes Road, Condobolin but an unknown disease wiped them out a few years ago.

Planting by the Moon Tips

  • Giuseppe Chessa and his parents own a fruit farm north of Brisbane, and in the past have specialised in growing persimmons and figs. However, a year ago, Mr Chessa decided to plant dragon fruit and is now converting large parts of the farm to grow the spectacular fruit on a commercial scale. “None of us have an idea or clue about where the idea to grow dragon fruit came from,” Mr Chessa said. “But it has been a lot of work, a lot of stress and a lot of headaches. Giuseppe’s mother, Pina Chessa, started the farm with her husband 35 years ago, and in that time has experimented with many different crops. “We are doing persimmons at the moment and figs, eggplants, zucchinis, tomatoes, sweet potato, we have done a lot,” she said. “Hopefully this will be the last lot of experimenting. I’m not young anymore!” Although the Chessa family said there were many unknowns about the dragon fruit venture, they had some family farming techniques they hoped would guarantee its success.
    “We plant when there is a new moon, so that is when we planted the dragon fruit,” Mr Chessa said. “There are a few rows we planted where nothing took, but where the new moon crop is they are already a metre and a half high. I don’t know why but they grow better. We plant during the night when a new moon is coming.”

Plant Collector Tips

Print this entry

I hear stories of specialist rare fruit collectors who don’t share. What happens if you have a problem with your tree? The issue is that if you keep the plants to yourself and you die, then your collection dies with you and this is really sad as you’ve spent your life having a wonderful interest and it is all in vain. Leave a legacy…

As I’ve mentioned many times I’ve seen very good responses in growth on a variety of fruit trees using Phosphorous Acid. Pitombas increase in growth was amazing. Ref:  George Allen

Pineapple Tips

  • Coconut-flavoured pineapple created in Queensland
    Queensland researchers have accidentally created a coconut flavoured pineapple. Soon there will be no need to mix your own pina colada – Queensland researchers will get nature to do it for you. The Department of Agriculture has created a new variety of pineapple that tastes like coconut. Senior horticulturalist Garth Senewski says the AusFestival pineapple has been 10 years in the making and is now in the final stages of production.”Taste tests tell us that AusFestival is a winner – it has this lovely coconut flavour, which you won’t find in any other pineapple in Australia,” he told the ABC. “It’s sweet, low acid, very juicy.” He said researchers did not intentionally create a coconut flavour. “We’re looking for a nice flavoured pineapple,” he said. “We’re looking for a variety that is sweet, low acid and aromatic.” The new pineapple is likely to be commercially available in two years.   Ref:  Brisbane Times
     
  • John Ambrose from Nambour wrote to say that it is recommended that Pineapples not be grown on a southern slope. A grower told him that around Woombye these plants could be very prone to Blackheart, a number of dark patches in the flesh of ripe fruit. 

Phytophthora Tips

  • The latest seems to be that phytophthora growth is pushed by high nitrogen levels with low carbon and low calcium
  • Supplementing with calcium and carbon and avoiding nitrogen is indicated if you have a problem. Ref: Dwight Carter 
  • How do I know if I have root rot in my trees? The best way to determine if trees have root rot is to scrape away the mulch layer under the trees and examine the feeder roots. Root rot shows up as black roots. Check the picture of root rot in the Problem Solver section of the information kit. If you are in doubtsubmit a sample of roots and soil for pathological examination. This is best done in spring and summer when the soil is warmer and the trees are growing more actively.
  •  What should I do to protect newly planted trees from root rot? The best way to ensure the trees are healthy is by buying only ANVAS accredited trees. Then apply metalaxyl granules around the tree straight after planting. Repeat this six to eight weeks later. Also avoid planting new trees in areas where you have previously had major root rot problems, or on slopes below existing orchards. If the new trees are being planted in a new block of land, try to isolate it from existing blocks and disinfect machinery before it is brought into the new block.
  •  Do I need to treat healthy trees for root rot every year? Yes. We recommend that even apparently healthy trees be injected with phosphonate fungicide at least once a year in early summer to keep them healthy. Alternatively, apply six foliar sprays of phosphonate fungicide between spring and autumn. Trees with mild to severe symptoms should be injected twice a year. Foliar sprays are also recommended for trees with a small trunk diameter (less than 4 cm), where trunk injection is impractical.
  • When should I inject my trees? Timing of injection depends on how severely trees are affected by root rot. If trees have no visible symptoms, inject once in early summer, six weeks after the end of the spring leaf flush. It trees have any visible symptoms (yellowing, droopy leaves, leaf drop), inject twice a year. The timing of these two injections depends on the severity of root rot symptoms. For trees with mild to moderate symptoms, inject as soon as most of the spring flush has matured (late November in south-east Queensland), and again in mid-March. For trees with severe root rot symptoms, inject at the start of spring and then again in mid-March.
  • Should I plug the injection holes after I have injected the phosphonate fungicide? No. We recommend leaving the holes as they are and allowing them to callus over. However, if high pressure injection devices are being used, holes may need plugging after the injector has been removed to prevent leakage of fungicide from the hole.
  • Can I spray the phosphonate fungicide on the ground to control root rot? No, because phosphonate fungicide breaks down very quickly in the soil and consequently doesn’t work well. It is also likely to encourage the development of strains of the Phytophthora fungus that are resistant to phosphonate fungicide. The fungicide works best when it is applied to the leaves or injected directly into the sap.
  • Can I spray phosphonate fungicide on my trees rather than injecting? Yes, but sprays of phosphonate fungicide should only be applied to apparently healthy trees. Don’t use foliar sprays on affected trees, as they are less effective because of insufficient uptake. Six sprays are recommended between spring and autumn, with no more than about four to six weeks between spraysSpraying the fungicide can cause a problem. Leaf and fruit burn is likely if phosphonate fungicide is sprayed seven to ten days before or after sprays containing dimethoate, if it is applied with copper hydroxide, or if copper hydroxide residues are present on leaves. A risk may exist with other chemicals as well, depending on the quality of the water used in the spray mixture. As a result, it is often difficult to find at least six ‘safe’ spray points between spring and autumn. An additional problem is that phosphonate fungicide cannot generally be mixed in tanks with endosulfan insecticide because of spray incompatibility.
  • How do I apply phosphonate fungicide to trees whose trunks are too small to inject?  Use foliar sprays instead (as outlined previously) or use metalaxyl granules on the ground.
  • What should I do if a tree dies from root rot and I want to plant another in its place?  Move a little distance away from the site of the dead tree and spend time preparing the site. Dig it over, check the pH and apply limeor dolomite as required, and put on some organic manure. Mulch the site and leave for a few months. Then apply metalaxyl granules around the tree at planting and eight weeks later. Remember to adjust the irrigation emitter and fertiliser rate for the smaller size of the newly planted tree.
  • Sometimes I get leaf burn after injecting trees. Is this a problem?  Leaf burn is not a problem if it is only on a small part of the tree. If it is more severe, it could affect growth. Check the phosphonate fungicide rates that you are using, inject trees only when the maximum daily temperature is above 23°C, and use a phosphonate product that is buffered to a pH of 7.0.
  • Phosphorous Acid As I’ve mentioned many times I’ve seen very good responses in growth on a variety of fruit trees. Pitombas increase in growth was amazing. A lot of trees suffer from this disease and show these symptoms in the form of crippled growth, tip die back & also leaf tip burn, of course some plants inevitably die, such as Avocados and Jarrah Eucalyptus marginata (a Myrtaceae as is Pitomba). The amount of plants that are registered for use with this spray around the world is enormous. Soluble silica is quoted on the web as having controlling effects on plant health and phytophthora resistance. Ref: George Allen

Persimmon Tips

Print this entry

  • Persimmons by Jason Spotswood   After the field trip to the persimmon and avocado farm in Nambour, I had heaps of non-astringent persimmons to get through. We found that we were unable to utilise them all before they went soft and risked spoiling. So I started putting the soft persimmons in the freezer while their skin was still able to contain the soft insides. I froze them one layer at a time, only putting new ones to freeze on top of the previous ones when they had frozen completely. For the most part they have been able to maintain their shape and form while in the freezer (I still have persimmons in the freezer in November). Our freezer does not have automatic defrost, so I am not sure if prolonged exposure in a defrosting freezer would cause excessive freezer burn or not. I have not tasted any issues with freezer burn in my freezer. Most of the time I use the frozen persimmons in smoothies. I allow them to slightly thaw and then cut off the calyx and drop them into the blender. There are also other great recipes from the Custard Apple and Persimmon Recipe Book which can use the thawed persimmon pulp; such as Glazed Persimmon Biscuits, Persimmon Sherbet, or Persimmon Cream Pie. Here is my Smoothie recipe:
  • Persimmon Smoothie  In a blender: 1 orange, 1 large or 2 small bananas, 1 whole soft persimmon, calyx removed                         Optional:  add yogurt to taste. Add water or ice to make it more liquid. Ice is handy to use when the fruit is room temperature as it cools the drink down.
  • Autumn – Apply plenty of Phosphorous eg chicken manure. Harvest when fruit is fully coloured.

Pepino Tips

Print this entry

  • In NZ, Pepinos are grown in pots with three long bamboo stakes. The plant is cut off low to the ground and when it multi-trunks after being cut, the vines are trained up the stakes.
  • New Pepino plants require the centre to be pruned out and doing this encourages an open bush allowing greater light penetration and air movement.
  • A wire trellis in the form of a pyramid is needed to support the plant, keeping it upright especially when in fruit.
  • It is very susceptible to fruit fly, you either have to net or bait so design your trellis accordingly.
