Brad starts with ... So we all know slip slop slap for people but is there consensus what we do for (various) plants? There's lots of loose information on this site about sunburn (especially avos), but no specific comparison of various approaches. my question in this area started with one of my 3 young blueberries under shade cloth showing a very few burnt leaves after yesterdays 41 degrees. (I guess I watered too little). Because I don't fear more sunburn I removed the damaged leaves. But I guess in most cases you would leave them to shade the lower leaves - right? so: What to do (not do) once a tree is sunburnt? What preventative measures do you recommend (e.g. polymer, calcium carbonate sprays, shadecloth, other trees, extra water, don't worry about it) etc | About the Author Brad2 Como, Perth 18th January 2010 2:47pm #UserID: 2323 Posts: 762 View All Brad2's Edible Fruit Trees |

Mish says... Hi Brad I have been using 'Drought Shield' from Yates (If I remember correctly Amanda mentioned it on another thread). It has been really effective against sunburn on the foliage, and helps to protect young leaves. I have sprayed my Persimmon, Mango, Lemon, Nectarines and Longan trees. I have a few trees with sunburnt leaves, but these were already burnt when I purchased them in similar heat conditions a few weeks ago. So since using DS no new sunburn has occurred. I didn't remove the leaves as they seem to still be viable (green in the middle). My Pomegranate seems to be coping well with the heat. But it doesn't do much for my avocado (Wurtz) in relation to heat exhaustion, although no leaf burn, it has suffered droopiness. I have moved it to a more shaded spot, and watered gently this morning but it was droopy again by 10am, so I had to construct more shade. I'm reluctant to water it again as it is still moist and Avo's hate being too wet. Apart from telling 'Mr Wurtz' to "Harden up", I have constructed more shade (scrap wood and a moving trolley) to block the sun pretty much all day. But I definitely recommend Drought Shield... | About the Author Mish Singleton 18th January 2010 9:58pm #UserID: 3045 Posts: 42 View All Mish's Edible Fruit Trees |

amanda says... Good info Mish! - I still haven't got around to spraying mine :-o Sunburn is interesting - we have had 4 days in a row of 40 to 46 degrees. I haven't seen any sunburn as yet - but I have kept everything very well watered (every day) I wonder if this is the answer. Or it could be that my trees are in full sun always - so toughened to it. I try to keep a lot of foliage on my trees too - this helps protect the bark as well and shade the mulch. Parasol is the other organic (?) remedy. | About the Author amanda19 Geraldton.

No gimicks says... I work retail in a garden centre. from what i have observed, in a practical nature, good soil, regular, sufficient watering and a GOOD all purpose fertilser with microbes, combined with a wetting soil agent is all you need. And a suitable mulch which will break down and add to your soil is all you need. Oh, and timing and amount of watering is critical; moist to dry and during the day not in the evening. Any thing else and you just add to someone elses pocket! | About the Author No gimicks Mundijong 20th January 2020 10:42pm #UserID: 21495 Posts: 1 View All No gimicks's Edible Fruit Trees |
