In the last week I've brought 14 new AVs into my home from Bluebird Greenhouse and a DG 's member. I've check them over and they all look extremely healthy. They've been in separate rooms from the beginning but i wonder how soon I can put them together?
.You should keep them separated for a few months at least. However, I am pretty sure I know who the DG member was and I am sure her plants are just fine. I have never heard anything negative about Bluebird. It is always better to be safe than sorry. I placed 3 consecutive orders from a vendor and put them together. I didn't see any reason to separate so I had a mess because the last order had mites. More tears than anything because I didn't have any chemicals to kill them and I had to throw them all away.
How dreadful Connie! It would only take one incident like that to adhere to strict isolation. Sounds like you gave good advice.
Connie- Thanks for passing on your hard earned knowledge. My AVs will stay right where they are :). I went from 2 plants to 19 plants in just 2 weeks so I need to let things settle down anyway.
I have found that, while not getting rid of mites and thrips, Neem Oil can be a wonderful and (almost) non-toxic way to control a small outbreak of aphids, mealy bugs or even mildew. I tend to (aside from quarantine and visual inspection) give plants that appear iffy or have a few blind passengers on board a good spray of Neem before putting them into a sweater box or similar enclosure for quarantine.
If you don't mind "chemical warfare", you can always apply some granules of Orthene or a similar systemic insecticide to the soil (follow instructions). That should get rid of almost everything.
I have to say that I have been quite successful with Neem and other less or non-toxic remedies and I prefer to keep it that way.
If you have healthy plants and keep your growing area clean and follow simple preventive measures like quarantine, chances are that you will never need the harsher chemicals.
Neem oil also has some effect on mites,though it may not totally erradicate them.
