Think it might be too cool for them Derrick

That's disappointing for you, Cairnsie.

Normally they germinate in 7 to 21 days, the ideal germination temperature is 10/15c day & night.

Of course they won't germinate outdoors in the winter, but can be germinated indoors then transferred to a cooler location later.

i have bought 3 inch pots for a pound with quite a few sweet peas in from b &q do i seperate them now, when i plant them or leave them together?


05/04/2013 at 18:15

They really don't like root disturbance, so I think I'd leave them together - how many are there in one pot?

05/04/2013 at 18:59

about 7 so quite alot i just needs a few to boost what i have already grown

18/04/2013 at 22:00

Think it ay be time to get mine planted out this comming weekend.

18/04/2013 at 22:39

I got to sow mine yet - me bit behind, Bev it should be good time to plant out your plants

18/04/2013 at 22:48

I've got some I planted up before Christmas which are nice stout little things and then I intend to plant up more seeds so they are a bit behind to hopefully keep my display going on longer. Need David K to advise- he knows his Sweet Peas

18/04/2013 at 23:27

Mine from before Christmas look great, the others I sowed acouple of weeks ago and are just beginning to poke through. Is that any help?

I have only just started some off as recommended by a sweetpea breeder. You put the seeds on damp paper, kitchen roll, cover with cling film and wait for the root tip to appear brfore planting singly in pots. Keep the kitchen roll damp buy not soaking.

I grew nearly 500 last year for a family wedding was cancelled so thought I would give them a miss this year. However, I do love them so belately, have sown about 40 seeds. Different varieties seem to germinate at different rates. Last year I sowed the seed in the autumn and grew them on in a cold frames through the winter, strong stocky plants and early flowering. It will be interesting to see how this years effort does, last year was not a good year for sweetpeas.

Mine are all planted up today i just had enough for what i needed so pleased i got a few more to germinate also. looking forward to the display.

Ive sewn 2 seads in each pot and they all seem to be germinating well. Should I thin out the weakest plant in each pot, or leave them alone?

I planted out some of my Sweet Peas yesterday

 I also tried to germinate others in the way Joyce described above on wet kitchen paper.

Thanks David.I am a gardening novice! Will let you know how I get on!

Hi i hope im posting on the correct page.

My sweet peas have what i think is powdery mildew. They are out in tubs/containers and i want to cure them before it's too late, they are about 7-8" max at the moment.

Im hoping you may have some good sugestions on a home remedy as i cant get to the shops this week. But any info would be great.

Regards Tom

Hi I've looked at a lot of sweet pea posts on here, dont think can find answer, I,ve sown my seeds march and some april, I nipped off growing tip...could i have done this too early? They still look very straggly...i saw a gardening programme whwere one old chap chopped his in half when they looke dlike mine, is this a good idea? Never had much luck with sweet peas, am soooo determined this year to have masses of flowers!!

11/05/2013 at 10:46

You could nip the tips of again they should be fine and grow stronger and side shoots as well, I have nipped my sweet peas in the past before a few times till they came out nice and strong

Mine are now showing and will be going into the plastic greenhouse sowed later as last year too early and did not grow at all

11/05/2013 at 18:13

THanks, I've put them outside today and I'll nip tops off again tomorrow

21/05/2013 at 22:07

I did that...looking rather straggly still...slugs been round the few already in ground that were doing ok,why can't I grow great banks of sweet peas loke I remember my friend's grandad growing when I was little?
