Re: chrysblue
I also practice bonsai. Recently moved to another county and 2 months in I have a big whitefly and fungus gnat problem with many of them.
Last night I put a bucket of ladybugs out in amongst all my bonsai. But I am scared for them and want to spray with pesticide tonight,mwhich would kill the beneficial ladybugs I just introduced. Any advice?
Every time I have had petunia's I have a problem with those white flies, this time they have attacked my bonsai ficus tree , not sure how to spell it but, I treated with just soapy water and they disappeared but came back 3 times now almost killing the tree, then it gets recovered and wham , they are back so I hope this time with the alcohol added it will work better, and I have lost one dill plant so far .
Excellent advice
I am attempting something of a different approach. Incense. I have been trying to smoke em out. the garden beans seem to love it. more leaves forming now, as before the plants seemed to be stunted. not sure if the plants are reacting to the weather or the incense? the temp highs have been nearly unchanged. overnight lows petty much unchanged. anyway the flies are still present, but I have only burned the incense twice. keeping them up wind and safe of course from fire danger. I only do this while i'm tending the garden. it takes me about 1/2 hour to water all my garden. I now use 8 gallons a day. was 6 but the plants I started with were doing so well that I planted 8 more types (cabbage,cauliflower,parsley,onion,pea,spinach,squash,a yellow garden bean)and a neighbor informed me or the marigolds so they are throughout my garden now,well they just broke ground 3 days ago. I sure hope I don't lose the garden due to heat. the 8 gallons is split 3 times a day. sunrise then between 11:30am-1:30pm depending on soil moisture then before sunset. I keep the two 1 gallon milk containers and two 1 gallon water containers outside during the day to water with ambient temp H2o and inside at night for high 60deg H2o.
Whiteflies can be determined with strong-smelling plants—and that may be how/why the strong aroma of incense is working. The marigolds should help, and nasturiums, too.
Another idea for deterining whiteflies is reflective mulch. Speaking of mulch,make sure that your plants have some. It can be store-boughht bag stuff or even newspaper. It will help the soil retain moisture, which your plants will want more and more of as the season progresses. Good luck, Martin!
I am not able to log in says my name not a user yet heres my post
Previously we have lived in Phx 17 years and in CA 23 yrs and here in San Diego area 13 yrs. only 4 yrs ago have I encountered whitefly. At what point do we cut down the plant? My mature hibiscus was afflicted twice and now they have moved on to mature Flax plants. I fear they will just keep moving on and never be controlled
White flies have infested my tea leaves, can I wash them with insecticide soap? Also, would I be able to boil them to make tea?
Thank you.
