I thought my 18ft Cordyline had survived the bad winter as it continued to grow and flowered recently but this week I noticed the bark is falling off about a foot from the bottom of all three trunks... Assuming that this tree is now dead I am going to cut it down and let the new growth which has appeared out of the ground to continue to grow.. I was wondering should I leave the stumps of the remaining tree bare after I cut them or should I treat them with something?
I have bamboo planted at the end of my garden border, which I planted 2 years ago when my knowledge of gardening was zero, although it looks great, I am hearing lots of horror stories about running bamboo destroying gardens. It is around 2 metres tall at this time and it's spread is quite compact. I don't want to remove it but would like to know how to manage it if possible. There are flowers planted right next to it, they seem to be thriving so maybe all is fine but thinking of the future! How can I tell if it is clumping or running bamboo?
I planted some winter onions last Oct/nov.. they have developed into what I would call clusters of what look like large scallions. I have misplaced/lost the info sheet and was wondering if winter onions develope into large onions or into groups of shallots and when should I harvest them? Very vague question....sorry.
