Phyllostachys aurea, in a pot or planted in the ground?

Post by Al » Sat Aug 25, 2012 10:02 am

I have 4 of these in their pots, and look healthy, how invasive are these? Will they do better in the ground or play safe and keep them potted?
They are roughly 9ft at the moment, so a decent height.

Thanks for the replies in advance.

Being a running bamboo, its advised to plant with a root barrier to keep them in check. However, if they are healthy why cause more work?
If you planted without a containment plan, you could always go round in the autumn removing stray culms, but when they've established and are happy, they will seek out new ground....not a problem if your garden is half of East Anglia like Sir Kristens! :D

I have 6 planted out & 4 of them are over 16ft & very thick culms, but all the new growth is nice & tight in a small grove. I've asked loads of advice even from people who have them planted in dry loamy soil & there quite well behaved!!, mine are in clay after 6inches so i doubt they will move very far, i'm told the rule of thumb is to keep a close eye on them & abort ay unwanted culms. karl.

Thanks guys.

Would burying them in their pots contain them without using a barrier?

It's advisable to use a barrier that is at least 2ft deep so if you were to plant in the pots it's possible that runners may burrow through the holes in the base of the pot and escape that way.

I planted 3 out this year, one in a block-built raised bed, one in the ground without a barrier at the back so it will hopefully spread outside my garden and one using a home made barrier made from those carpet protector plastic things that come on a roll.

I just stuck 2 back to back then rolled out the length I needed. Way cheaper than root barrier but as yet unproven. These things are designed to withstand stillettos so I imagine they'll be resilliant enough to prevent bamboo escapes and at a total cost which is less than a quarter of the price of the specialist stuff.

mine has behaved so far in the ground for 3.5 years.if it gets out of hand i'll root prune like i do with all my bamboos.i think its behaviour depends a little on your location. its quite cool comparatively here in mid wales so bamboos tend to have more of a clumping behavior.

jacko, thats what i was saying about different soil conditions, i believe with a more claggy tight growing medium people should be ok with this species, i like your idea of root pruning as opposed to culm pruning as this would keep the grove tidy, jacko i will have to pay you a visit one of these days to have a look & get a few tip's off you. karl.

the idea with soil conditions to help contain them isto make a lovely loose area where you want them to stay and compact down under where you want to discourage

Ken, you are correct i plant in a good quality peat/soil for first planting then they hit the claggy stuff!!. karl.

your welcome karl. :D another method i have read is to keep the area where the bamboo is planted moist and fertilzed whille the soil outside of that is kept dry and impoverished.the idea is that if the plant is recieving plenty of moisture and nutrition where it is growing it wont feel the need to wonder.bit sceptical myself on this one.

Hi,

Goldern bamboo can be quite invasive when it gets it feet in the ground, so you will need to place a barrier around the running roots if planted out. like others have said it can be root prunned... which is easier said then done

So the best advice would to leave them alone if their happy

Gray, when you say golden bamboo do you mean aurea sulcata or vivax autacaulis? ,i think the soil down your way must be very light & sandy as Dave brown has previously mentiond his phylly nigra running like mad!, as mentioned a tighter heavy clay medium seems to slow them down a lot. I think the main issue root pruning is that once a grove becomes well established the ground around it becomes a solid root mass, meaning a very sharp bolster or similar to remove excess. karl.

Hi Karl,

Golden bamboo as said, for Phyllostachys aurea. I believe aurea sulcata is called yellow/grove bamboo and vivax autacaulis called gold vivax which is a newer type.

Our soil type down in Gravesend varies from flint and chalk - heavy clay - sandy and stoney ( near river. where Dave lives).

root pruning only really becomes a problem if you dont do it annually.... late autumn is the best time after they have finished growing for the season.
