I have just received an order of 5 alstroemeria 

What has come isn't quite what I was expecting, though not sure what they would be like.

These are long thick root typw things, bit like an eremurus crossed with a dahlia - not a good description

Packaging says plant horizontally, however for now they have to go in pots and am unsure (totally flummoxed) what to do with them. If I lay them as dorections I will need really large pots for each one and not sure I a) have enough large one and b) can accomodate them.

All help and ideas accepted

what i  do with bare roots like those is to put a little compost in bottom of a pot then try and spread the roots out like a triangle of the roots wirth the base of the pot as the base of the triangle and feeding more compost in between. Aim for the crown to be 2 inches bellow the surface. I have used 1 litre pots for alstromeria before. I hope this makes sense. I would draw a picture but I dot think you can do that with the tools on here.

Yes, i have just done that.  Use ericaceous compost and water with rain water.

In last house we actually couldn't get rid of 'em as they were one of the few things bunnies didn't eat! We had acid soil and it was quite rich where most of them were sited and right next to a down pipe so Marion's advice sounds spot on. Once established they seem to spread very readily (even under weed control fabric!) if happy. They also seeded around very freely as well and I transplanted some to other areas of garden.

Thanks all, will pot them up tomorrow - more indoor gardening

Rosa they can be slow from bare roots. I grew the so-called Princess lilies .just 3 varieties but they were wonderful in flower. Trouble is they become somewhat dormant in mid summer leaving a big gap in he border. To overcome this I dug them up to replant behind perennials that disguise this gap. Alstroemerias do spread so best where they can't "bully" their neighbours. The varieties I grew didnt seed .i grew hybrids...but still a bit thuggish

Think I will put them in big pots as one of the many things to do when the ground has thawed is a soil test or 2.

How acidic would they need?

Rosa, not sure if acid or alkaline soil is important. I guess very acid soil would not be good.
I have always thought they need good nutritious soil and sunshine. When in good growth i try to give them a mulch but often forget! Mine are in such conditions and flower for ages.

I have friends who grow this successfully in the shadow of the South Downs, very chalky and definitely no acid in sight. They gave me some clumps in the Autumn to replant here and I am following this thread with interest.

So for now could I pot them into MP or should I mix a bit of ericaceous in with it?

27/03/2013 at 14:05
Rosa simple mpc is fine
27/03/2013 at 16:01

Let us know how you get on Rosa as I and my friend have lost bare root and pots of alstroemeria in our gardens repeatedlt in bristol's alkaline soil.  Perhaps neutral is required.  Mine are being cossetted in ericaceous compost in pots this year.  It is a flower rarely seen in gardens round here.  In fact I do not know anyone who has had success.

 forgot to say I have seen many slides of them in their native habitat, in hillside, very acid woods in Chile.  These are the species and in all kinds of lovely colours.  We are building a Chilean garden at the Bristol botanic Garden so i am hoping to learn from that.

Just potted them. I had some longer than usual pots that you get climbers so have put them in those, on bottom shelf in GH till they get going.

Like planting spiders

Roots can be slow....can sulk a bit
28/03/2013 at 13:47

Love that - like planting spiders.  It was!

hope you have great success with your plants I inherited mine from selfset seeds from my neighbours garden quite a few years ago and everyyear they put on a marvellous display my soil is neutral on a veryshallow sandstone bedrock base but they seem to thrive on it.it's great to sit out inthe garden with the old G & T when the seed pods are ripe it just sounds like loads of champagne corks popping as they distribute their seeds for yet more plans next year.

Oh, I love orchestral plants.  My Tulipa turkistanica close up their flower heads (three or four on each stem) when it goes cloudy to protect the pollen from the rain.  When thesun shines again they pop open making lovely music in the garden till all are open.

I live in Orkney I planted alstromeria ligtu hybrids from seed. They seeded all over my herbaceous border reverting back to species. I have had to dig up the whole border, taking barrowloads of thick white tubers out of the ground. I would certainly not plant them again . Maybe pots are the way to go. The tubers are two spits deep right down in the clay subsoil. I think I will be digging them out forever.
