This question was asked by
Can I reuse the compost in a container after weevil grubs had attacked the previous tiarellas?
I poured two full kettles of boiling water into the container – several grubs came to the surface!
It is now nearly 2 months since I rescued the plants, having left them exposed for at least 24 hours, dousing them well in running water before repotting them. They are thriving indoors at present but I would like to return them to their container – without having to change the compost!
Is this possible, if I use nematodes?
Thanking you for your advice.
PS. The other 6 heuchera I purchased from you in March last year are thriving.
Hi Rosaleen
Yes that should be no problems
Really pleased you managed to rescue them
Nematode when the weather is warmer.
The Nematodes don’t survive in soil temperatures below 6C
We do June to October
Always keep an eye open for the pesky VW
Pleased your others from us are doing well 😀
Happy Heuchering
