My anemones are now in their fourth year. They have finished flowering for this year but I'm sure they will flower again next year.
They are not really ready to be harvested until the foliage has dried up, but you can take onions for the kitchen as and when you need them. Let the foliage keel over naturally - don't help it!
The very best way is to dig out the roots. No weed killer required. Weak growth will come from some of the roots left behind, but easily disposed of. The dug out roots will burn well. Good luck.
Do not cover the foliage. Just pile up the soil to cover the lower stems and the potatoes to prevent the light getting at them.
They are edible if you need the space.
Donate it to a park. anonymously if necessary.
Yes but the plant needs its leaves. By all means cut them off after you have gathered the fruit. Not before. I guarantee the fruit will ripen despite the foliage.
The easiest way is to make a former and wind wire around it to make wire hoops. Then you just stick the two ends in the ground over the plastic. Do not be too ambitious and buy sheets that are too long. Several shorter ones are more useful. And remember to secure them or the wind will take them!
Let this be a warning to anybody tempted to buy any sort of trap. Please work out beforehand what you are going to do with whatever you catch. This applies to squirrels, rabbits, rats, magpies and mice; or anything else.
I would suggest you do not plant a tree in the lawn. It will drive the person who does the mowing to distraction. Plant it in a border if you can.
