Read lots and lots about D earth and it does seem to be indiscriminate but so are most things...except perhaps Neem.  Certainly most sites recommended not using around flowers (bees) and I wondered if they would take it too their hives!  One person said she had used it for years and had lots of worms in her garden.  I plan to be careful as am with all things that kill.  It is good to have something can use w/o worrying that it will hurt people.  A glasshouse seems to be a good place to use it.  We are going to put it on the leaves and branches of the fruit trees and also around them because the cicadas are so bad where we live.  Thank you Matt and Ingrid for your advice and suggestions.

dosn't matter what you use it would be indiscriminate but if you want a safe method DE earth is the safest friendliest product out there out there

I would be worried about using diatomacious earth widely - it seems to be a pretty indiscriminate killer of every insect. I want to have a healthy ecosystem in my garden. Maybe its good for very localised applications?

Hey Matt, that is a really good site for D earth, I didn't even know it is good for people too.  Only used it for insects inside the house in Hawaii.....so many cockroaches and ants there!  Thanks for taking the time to tell me about it.  Cheers and happy holidays

De earth can be used in the garden even with all the rain I mix a cup or so in a 5 liter sprayer and apply it in spray form Food grade de earth is costly hear is a link to a supplyer as well as a very goot info web site http://www.denz.co.nz/

Thank you for that suggestion D & D!  Hope to have a friend now in Auckland to find some diatomacious earth.  Will also try it in the garden but probably be less effective there because of rain.  Still, anything is better than leaving them to multiply.  Am new to glasshouse planting but have grown lots of seedlings in there so far and kept the tree seedlings during the winter.  Thanks again, happy holidays and cheers to you too.

Hi : For white fly, Dian recommends companion planting mariigolds, and dusting with food grade diatomacious earth.

Cheers,

D&D

Does anyone have an affective way of dealing with white fly in glasshouse?  I have sprayed with water, soap, pyretheum (sp?) and then washed off but the veg plants really do not like it.  Tried the trick of yellow color with sticky on and a light at night time with water under it which also got a few. Are there plants that white fly don't like that I could plant with others to hide them a bit?  Any ideas welcome.

Miranda Robinson - Its impossible for anyone to advise you without more information - it could be the growing medium, pH, nutrient deficiency or imbalance, soil moisture, irrigation, drainage, humidity, airflow, temperature, fungus, virus, bacteria, micro-organisms, pests, propagation techniques, timing, seed quality or varieties. I would read three or four books on glasshouse growing to begin to grasp the fundamentals, then you will know where to start looking for the answer. Im currently reading my tenth permaculture book.

Hydroponics anybody. Take a look at the new hydroponics and aquaponics group just started up.
