help with orange trees!!!

[spanish sheep]

i bought two orange trees about a month ago and planted them out side, unfortunatley we had freezing and snow ( all of which was not forecast!!) so they got caught all the new shoots have gone black and fell off which we expected to happen after the snow!! the leafs have also gone an odd colour, we thought we had killed them :( but we have noticed new shoots and are hoping they will survive..... now my question is: i have been told today i need to spry them with pyrinex so that they will blossom? i have no idea if this is correct ? but i would like to keep my tree's as organic as possible. could anyone tell me why i need to spray them and if it is indeed organic?

confused

Hi there,
Well, Pyrinex is an insecticide! Not sure how organic it is.......



Spray your orange trees with the hose once a week. This knocks off eggs, larvae, and worms which you can gather up and throw away. Wrap them in a plastic bag and put them in a trash container that is far away from the trees.

Check your orange trees carefully for pests at least once a month. Look at the branches and the undersides of leaves where insects and eggs often collect. Clip off any severely damaged leaves or twigs and throw them away.

Hi,
To answer your first question, no, strictly speaking pyrinex is not organic, nor will it help with frost damage. It is a broad-spectrum organophosphate insecticide that acts by contact, ingestion and inhalation of soil insects such as white grubs, wireworms, Hylemia, cutworms, Screwworm in farms, vegetables, fodder and industrial crops.

In other words, its a man-made organic pesticide containing phosphorus, eg mathalon, an insecticide that interferes with an insect's nervous system.

I totally agree with Eric, his suggestions are all good practises.

When a plant is damaged and it is dying back, it is always good to cut all diseased and dead matter away (as long as you leave something!). As these are young plants and they are damaged, they are more vulnerable to diseases and pests.

1) Spray with a weak solution of organic fertiliser to the leaves
2) Give the roots a chance & try to protect from wind.
3) Prevention is always better than cure - good, regular deep watering & feeding helps make a healthy plant.
4) If you are concerned about parasites try spraying the plant once a week with neem oil as this is an organic preventative measure. It adheres to the leaves and pests don´t like it.

Hope this is helpful, feel free to pm me for more advice.
