Could anyone give me some advice on how to plant them. Bought 5 at Schiphol last night as I always wanted to grow them. The bag doesn't give any instructions bar plant April/May. They are currently in the fridge awaiting your advice.

I have grown them in the past in a large pot  (but then, I grow nearly everything n pots so that doesn't say much really!), I used a mixture of JI2 and general purpose compost, gave them a reasonaby sheltered spot, they do come from the tropics, and they flowered fine for me.  If you did chose to do them in a pot, you may be able to keep them over for a second year, but I did not take mine inside so they did not survive.  Lots of very pretty papery petalled flowers, varied colours - nice.

How deep do you need to plant the tubers?
I'll probably plant some in pots and the rest in the border using normal compost with s bit of added grit.
I thought you could overwinter them as dahlias?

I've never kept the tubers, they're so quick and easy from seed and produce plenty of seeds so I keep them going like that. Less trouble to store seeds than tubers. Sorry Swedboy, not answered your question on when to plant. I'd get them planted, if a frost is forecast you can always cover them with some newspaper, there won't be a long penetrating frost now.

I bought a pack from Poundland last month, I planted them into pots & placed into the conservatory so far 2 of them have new shoots appearing.As for which way up to plant ,I found that 1 end was more rounded than the other so I kept the rounded end up.

If planting in the garden.  A sheltered sunny site, with a rich soil.

Whether planting tubers in the ground or pots.  From details posted.  It sounds as though just single tubers have been purcased/supplied.  In this case, simply lay the tuber flat.  Usually a well developed tuber will resemble dahlia tubers, where each tuber radiates from a center join that is the stem/stalk.  Plant tubers in April.  If planting inpots, then use a good general purpose compost.  Storing tubers, whether potted or bare tubers.  They should be overwintered in a frost free area....not in a fridge.


Seed sowing.  Sow seeds in JI No.2  February /March.  Young  seedlings and plant often attract loads of aphids, so be warned.


Hope this helps.

However propagating from seed is the cheapest and simple.

I agree Mike, the seed started ones are very quick indeed, large, easy to prick out seedlings and no messing about looking after tubers through the winter.

Never has aphid trouble though

Saved some seeds from last year so I better get sowing. Slightly disapointed that mine didn't smell much. That was my reason for buying them. 

Dug one tuber up and left the others behind. Suspect they have drowned now...

Plenty of time to sow, I do mine about now. Except that I forgot to save any last year.

Thebest scent is in the evening as with many plants.

I sowed my mirabilis and they broke the soil in two days they have got to be one of the quickest to germinate I've sown. Does any one know any other plants that germinate fast?

When can you expect the tubers to spring back to life again. The ones I had seems to have survived winter well have been back in the soil two weeks or so but no life from them. I am probably a bit impatient as I am eyeing up the pots for something else if they don't come back to life soon.

(had a littel dig about and the tuber looked fine but no growth.)

I'd sow some seeds, it would be quicker. I never keep the tubers. it's like Salvia patens and Nicotiana sylvestris, quicker to save and sow the seed

18/05/2014 at 17:39

How do you sow them? Just cover them up?

18/05/2014 at 17:43

I start them in pots in a cold GH. I don't think it's too late. Outside would be OK now maybe. I start in pots because my garden is so full of weed seeds and my seeds get swamped

Thanks. My garden is too small for such delights as a greenhouse of any kind. I'd love one but not enough space.
