Help with Acacia Seedlings - Acuminata and Courtii

Recommended Posts

Hi 

These acacia seedlings are about three months old. Mix of courtii and acuminata. Great germination rates and all looking good until a few of them mysteriously started to wilt and shrivel and have since died off (and removed). I'm used to losing a few throughout the growing process but these were looking great and can't help but think they should have survived if I'd done something different. Also concerned it may happen to the rest of the seedlings. Any ideas?  I'm in Central Australia so it's been nice and warm. They get morning sun and are watered a very tiny bit each day and misted a bit in the afternoon if it's particularly hot.  Cheers!

Check if any root grubs are in the pots. I lost tray after tray a couple of years back, the culprit was curl grubs. Not sure if you get them out there...

Thanks Glaukus, we definitely get curly grubs here, found a bunch in the compost the other day, but just checked some of the seedlings pots and nothing in there. Soil wasn't wet either which I thought might be an issue.

Well just an update... I spoke with the local nursery here and was recommended copper sulfate as an anti fungal treatment. They guy who runs it is pretty knowledgeable about growing acacia so I applied it to the plants - it is hard to say if it helped, certainly the ones that were already droopy did not recover - but they were probably too far gone. Many others are seeming to thrive - but they looked like they were thriving anyway so who knows.  I've always ended up losing lots of seedlings out of batches of seed I've planted, so I guess it's just the way it goes. 

But here's some pics of previous success stories of acuminata - these ones are around 13 months old and looking pretty good if I do say so myself.  Of course, the praying mantis love them. Hopefully this new lot of seedlings can match them one day. 

 

Keep growing everyone!
