I need a hooligan

[ClaudiaWinklepanda]

I have a triangular empty space behind my shed and I'd like to plant something there that will grow 3-4 m tall. However, I can't actually get behind the shed. What are my options? Is there anything that will grow that tall from seed that I can just chuck over?

Is it sunny? Some of the perennial sunflowers that grow from runners might survive if you wrap the roots in something and chuck them over. Also maybe Jerusalem artichokes

Sorry, no advice (though interested in your replies), but that is an excellent thread title.😀

Will it be able to get any water at all?

My lilac is a hooligan. I think if you took a few of its runners and chucked them back there there is a good chance they would grow. Might not stop at 3-4m though.

Any chance you can get a child to climb over the shed into the space or is it too narrow?

I'd describe it as shade/semi shade for the bottom 6 feet, but if it makes it above the shed it will get a decent amount of sun. It's open to the sky and at its deepest point there is about 1m between the back of the shed and the fence (the garden boundary is a triangle, hence me not being able to get behind).

I tried to make a child go over the shed, but there was reluctance. Maybe I could give it a go myself, but I'm a bit fat, so I'd worry about the roof collapsing.

In an idea world it would be something a bit airy, like a willow or a buddleia, I think. Or an actual tree.

Edited to remove rogue apostrophe.

I’ve a mass of buddleia seedlings in my gravel path from a nearby bush.

It’s called the butterfly bush because it attracts well… butterflies.

Ive heard ofseedbombing where you put seeds inside a little ball of soil and throw them onto soil.

Fatsia japonica

Would a fatsia grow from just being chucked over? Wouldn't I need to plant it?

Couldn't you ask one of your neighbours behind the shed if you could lean over their fence to plant something?

Sadly not, the fence is about 8 feet tall (solid bit with trellis on top).

buddleia is a good idea. Passion fruit might also work

Would hollyhocks work? Very tall, and should work from seeds dropped over the fence. Mine come back every year.

Russian vine?

Now that is a hooligan! OP might want to be able to access her shed in the future 😂

Buddleia would probably work - they grow anywhere - but once established they do need hacking back occasionally.

Could you climb on a ladder and drop a buddleia plant back there? I don’t think you want to scatter buddleia seeds 😂

What’s the ground like?

I’d expect a hooligan to arrive without help, unless something is preventing them from growing- dry/shade or weed preventing mulch in place. Are you sure there is soil there rather than shed base?

I'd be minded not to plant anything if the area isn't easily accessible. The problem with tall flowering bushes is that they usually grow outwards too, increasing in width each year as well as height. If you cannot easily control the width by regular pruning then there is a chance that damage could eventually be done to a fence or shed wall as the plant pushes against it.

I’m surprised you haven’t already got a sycamore

Ironically there is a strip of sycamore on the boundary at the side of the shed, but none seem to have braved the zone behind the shed.

Yes, I’m mindful of planting something there that could mean maintenance.

Hmm.

Willow istelf would work, no?

I would buy a bundle of whips and chuck them over, followed by a load of compost (a handful at a time if necessary) and either do it when plenty of rain is forecast or I would spray over with a hose daily for about 4 weeks.

Willw whips root almost anywhere so long as there is moisture - some would have to take
