Hullo fellow gardeners.
I planted some JAs this year and eventually (after lying skulking in the ground), they eventually grew to a fine height. The years before we had grown sunflowers as a kind of barrier from the street (for the wind, etc.) but the JAs did an excellent job as well as the flowers were really lovely. The only problem was I did not realise that they would grow so high so I should have put in some stakes from from the start.
I am not terribly keen on eating JAs and so my question is if I leave them in the ground will they kind of spread, like weeds, so that I have more plants coming up than this year?
