hey batgirl.. hows robin??? newbie huh??? ... many posts.. many worries ... gardening is supposed to be relaxing.. and you seem to be worrying to death ... if all your plants have a guarantee.. just freakin relax ... OK?? now.. yanking anything from a pot.. and sticking it in the ground .. disturbs its ability to pump water, because you messed with its roots ... make sense so far ... there is only one reaction .. it sacrifices leaves ... to which it could not pump enough water [especially if there was a heat wave immediately after planting] ... with me ... and here is the part you need to understand ... BEFORE YOU GO INSANE ... >>>>THIS IS NORMAL ... all the life in the plants.. are in the growth tips.. and even if it loses/sacrifices every single leaf.. if that growth tip thrives.. the plant will recover ... though it might look ugly for a while ... so just relax ... now.. could you have avoided this.. yes ... probably ... with the following: proper planting .... proper timing... a few weeks earlier would have made this all done when the plant had fewer leaves .. and the weather was cooler... leading to less problems pumping water ... proper mulching.. and proper watering ... if you read thru a few pages of back posts.. you ought to see many.. many posts about how to do it better ... and would be a great start to increasing your knowledge base ... but when all is said and done.. its nearly foolproof ... and me thinks you simply worry too much ... many say .. that you are not a true gardener.. until you have killed every plant in your garden 3 times.. and trust me... all of us have ... [and many years from now... like many of us.. you will wonder why you were so enthralled with a pussy willow.. lol] ... have a bat beer.. and relax.. odds are .. they will all recover.. the only issue is whether you will be certifiable before it happens... lol good luck .. we need more gardeners.. ken

I am assumng the products used are actually Impede and Neem oil :-)) And neither one should have much of a negative effect on a weeping cherry (although Lord knows they have enough other issues!!). Impede is just an insecticidal soap although at a somewhat higher concentration. And Neem oil is a go-to organic control for a variety of insect, fungal and mite issues. Both of these are contact insecticides, so "preventative" is a bit wishful thinking. But even so, unlikely to do much harm I would guess that the timing of the spraying may be playing a role. A wide variety of plants can develop phytotoxic reactions to insecticidal soap (or other pesticides) if sprayed during sunny conditions. This can cause them to lose foliage or it to burn and dry. If provided with sufficient moisture, they will often releaf rather promptly, given reasonable weather conditions.

being down under.. and it being fall .. and presuming its deciduous ... then i am never really concerned about how the leave look .. this time of year ... they are going to fall off.. and be gone ... in case anything was going on.. clean them all up.. so they wont be there in spring .. just in case ... i would have bought a fall plant with those leaves... ESPECIALLY if it was a fall bargain plant ... if you read that link ... you should know.. fall is one of the prime planting times ... especially on a deciduous tree ... since the various shocks.. will not really hurt leaves that are already primed to fall off ... all the better if they do.. fall is root growing time... and it will have all fall.. winter.. and early spring.. to get those roots settled in.. for the next time the leaves emerge .... NEVER water the leaves of anything.. that is ONLY ma natures job.. otherwise ... you water the roots ... leaves transpire or sweat .. lose water .. though they may take in some minimal water... its not really their job ... and if you water in the evening.. and the leaves go into humid darkness damp .. you could get in trouble with various night pathogens.. the most famous of which is powdery mildews ... since you suspect improper planting... as compared to the link ... and basically just yanked it from the pot ... at a min .. now that it has no leaves.. yank it back out... fluff out at least about half the MEDIA ... cut any severe circling roots ... and replant it in native soil.. per the link ... water it in properly .. and mulch it ... and then.. inserting finger about 2 or 3 inches ... dont water again. until the soil seems to be drying ... which.. in fall. might be weeks or a month from know ... no one can really tell you how it will all work.. in your soil ... and you are responsible for all water next year ... especially in the high heat of summer.. and any droughts ... the year after ... it should be rather self sufficient ... ken

because yellowing of leaves is usually a bad sign at this time of the year ==>>> not really ... its natures way as the plant shuts down for fall ... weather of course can complicate how early that happens ... and i am presuming we are talking about deciduous trees ... regardless ... there isnt much you should be doing in fall .. surely not adding any ferts, as the tree starts slowing down ... maybe some water .. i guess i dont understand your premise.. of what exactly you think you should be doing if the leaves turn color???? ken
