Agapanthus.

At a church plant sale yesterday bought an Agapanthus in a large(ish) plastic pot.

It does look like it could be split in to 3.

Would it be best at least for this year to be left as it is and/or split in the autumn?

I would like to grow my Agapanthus in a container and wonder if any GNers had success with growing theirs in a pot as opposed to in the ground.

It is green and healthy looking but without any sign of flowers at the moment, so I am wondering if it will probably not flower until next year.

Would be grateful for any tips or any advice.

TBH I would leave it to see how it flowers. Agapanthus love totally crowded roots and don’t flower so well if not in the right conditions. If you do split it, it will take a while to settle and may not flower for a year or two.

They are lovely though.

They generally do better in pots and the good thing is that you can put them undercover in the winter, all my planted ones were killed by frost last year!

I have three stalks which have shot up from nowhere, beautiful deep blue flowers when they open later on. They're a few years old and I had five flowers one year, though maybe one or two more may be hiding in the foliage as there are lots of leaves.

Thank you WW.?

I will change to a terracotta pot that is only slightly larger than the plastic one that it is in at present.

I would normally loosen the roots when planting but I will leave them tightly packed.

We have a sunny patio area that I hope will suit it sunshine

I have a few of these and they do better in pots where they can become potbound. I would not split it, at least not this year. They must self seed also as I have one growing between my paving stones. They are beautiful.

EllanVannin It was an impulse buy.
I have lovely memories of visiting the isles of Scilly and seeing beautiful Agapanthus almost everywhere.

dragonfly I would love if and when it flowers for it to self seed.

I am trying to grow more 'hard working plants' and cut the purchase of summer bedding plants down slightly.smile

I have read that they need a well a draining compost mixture any advice?smile

As others have said they like being overcrowded. I’d wait until after it has finished flowering before repotting. Terracotta pots dry out very quickly and plastic pots are advised! I know plastic!
I sometimes put my plants that are in plastic pots inside the decorative terracotta ones.

Cherrytree, I bought mine in Jersey years ago after seeing them everywhere almost growing like weeds but seas of beautiful blues everywhere you went. I too had to have one.

I got one last year and it has been in a glazed pot outside all winter. I didn't know they weren't hardy! It has got at least 10 flowers on it now. My glazed pots don't dry out as quickly as terracotta and don't crack.

DH says to water your agapanthus once every three weeks or so with cold tea. Apparently it's very good for them.

Cherrytree59 Mon 01-Jul-19 14:24:33

Glazed pot it is then folks.?
I will leave in the plastic pot for this year and just pop the lot into a glazed pot.

MiniMoon my grandmother always chucked the remains of her tea pot over her hydrangea.
Even when she changed to tea bags!
So will give tea tip a go.
Glad its only every few weeks, will have to wait for a tea drinker to visit.grin

This thread is timed well for me as I also made an impulse buy of an Agapanthus, from the Ideal World shopping channel yesterday, which should come with flowers and buds. I know they like to be pot-bound so will stand it in its original plastic pot within a glazed one for now. I haven't even decided where I can put it as I already have nearly 100 pots and baskets and not a square inch of bare soil to plant it out!

Keep it in a pot unless it has small, thin leaves in which case it will be hardy in the garden. I planted some of mine in the border but they are not very keen on flowering. They have large leaves.
If I was starting afresh I would buy the small leafed varieties for ease of looking after.
We put the pots under cover in winter. Just a cheap polythene arrangement by the shed.

I bought my Agapanthus at lunch time in M&S. Several years ago. They are a lovely deep blue. They do need some protection though.
It probably needs a a repotting to really get some energy back in. A job for the autumn.

J52 Mon 01-Jul-19 18:25:45

shysal you’re just like me,addicted to plants, I’ve lost count of the pots, but a couple of years ago DH counted 65. He had to move them when we moved house! Since then 10 potted Hydrangeas have joined in, plus some more.

My agapanthus is my pride and joy. It came with us in its same large pot from our last garden and has been in that pot around ten years. It puts out more stems every year - nine so far this year. When it flowers it is a glory.

Agapanthus is regarded as a weed here and flows like a blue and white tide down roadsides and verges. I think it's very attractive.
My sentiments are not shared by the Powers That Be.

People are encouraged to grub it out and replace it (if they must) with the sterile variety.

My agapanthus needs protection in winter and has to go in the garage. I have divided them now but I

I have lost some before. In the winter 10/11.

Iam64 Tue 02-Jul-19 08:50:52

Thanks, I didn't realise they prefer to be pot bound. I have one in a pot that is a glory and one in the garden which has lots of green leaves but few flowers. I'd been blaming the fact its now overshadowed but maybe not.

Lazigirl Tue 02-Jul-19 10:15:25

Thanks Bradfordlass. They are obviously indestructible which is why I've been able to grow one! I'm not green fingered at all and am always having to replace plants in pots. My latest venture is a monkey puzzle tree in a pot. (a big pot).

I snaffled a seed head from a trip to Madeira 14 years ago. I never got to pricking them out so they grew up extremely overcrowded and I just halved them when they broke the pot open! The leaves are very thin but they are obviously happy. This is a photo from last year.

I have successfully divided a big agapanthus without any problems. I also have a lovely light blue one with variegated foliage which is in a big pot and looks as if it might need to be split next year. 50 years ago, when I worked in Kenya, I had a long bed of agapanthus.

shysal Tue 02-Jul-19 14:25:04

My plant has just arrived. It is in a split pot and has obviously had one bloom cut off and another bud has broken off. I can't see any more coming. Will that be it for this year? It is a healthy chunky plant. I am now off to find a pot to fit which is only marginally larger.
There are no specific planting instructions, will it need a rich compost and/or additives or a basic one, considering it will only be a small amount? Should I get another plastic pot to fit snugly and just stand it in a nice ceramic one, which I originally intended if hadn't been split?
