How long does weed killer remain in compost? Can I reuse the compost?
Ok, so no judgement please, we bought a house so this is my first garden. When we got it, it's a new build so it was basically a ploughed field in the back. My husband put weedkiller down (using the bad watering-can, or so I thought) on the weeds that sprang up as we weren't able to get the garden done straight away.
Now its spring, I planted some seeds, I've done this before several years ago so I was happy with the process, and my herbs and plants were big enough so I transplanted them into pots (I'm not going to have a bed, just pots for tomatoes, garlic, herbs, peppers, chillies to start) i watered them with the good watering can. Next day, all dead. Turns out my husband had put the weed killer in the good watering can, and probably didn't rinse it out. (I dont' know which weedkiller it was. probably a generic off-the-shelf one)
My problem is. I don't have any more compost. I've ordered some through amazon but that's going to be another week, (due to coronavirus all the garden centres are closed and my local supermarket is only a small one) can I reuse the compost that I've got? Does the weed killer remain in the compost? I have more seeds so I can start to grow everything again, but I don't want to waste all the compost.
I admit I'm a complete newbie at this. I have grown some veg and herbs from seeds before successfully. planted them in the ground, they were brilliant. I have no interest in growing flowers, I'm more interested in stuff I can eat. :PJust when I really want my own herb garden, everything is dead. Help? Please?
