Can't seem to grow sweet peas

Posted by gardenper 8 (My Page) on

Just wanted them for the blooms and also saving the seeds so that I don't have to keep buying them every year, but I can't seem to grow them. They should be a cool weather plant, but it seems like cool weather time in my area (Zone 8) allows them to germinate but then just stay about 4-6" tall until it suddenly gets warmer, and then they die off.

Is it because my zone doesn't have a good gradual increase into summer temperatures (ie, 4 seasons) and instead just kind of goes from winter temperatures to summer temperatures? (Granted this year we still have cool temps even in April but in previous years, we had something like this and then suddenly we're into our hot temps)

I tried them in late winter/early spring as well as fall with similar results. In the fall, my area also kind of has the same issue. Warm temps even up until Thanksgiving and sometimes into December and then the temps drop to 50s or 40s for a while.

I know the feeling. I'm in 7b and by the time the soil is warm enough for them to germinate it gets too hot.

This year I sprouted them inside before I planted. They are looking good so far. I just hope the weather cooperates this year!

Are we talking about sweet peas (Lathyrus odoratus) or English peas (Pisum sativum)? Pisum sativum does well here in middle Georgia.

Just realized I used the word "crop" when describing them, but I don't intend to use them as a crop. I changed it to "plant". I mean the sweet peas, which I guess would be Lathyrus odoratus.

RE sweet peas

My peas are about 2 1/2ft tall and i havn't got any flowers on them.s this normal? I thought i will have had a lot of flowers by now.

RE: Can't seem to grow sweet peas

Are you planting in containers or in the ground? What's the soil mix like?

Seems like you should be able to get at least some peas to form. I'm thinking maybe a nutrient deficiency, hence the reason I ask about the growing medium.

I am attempting peas for a second time after an unsuccessful crop last fall. My peas vines were a good 3-4 feet long, but I didn't manage them well and they never produced anything.

RE: Can't seem to grow sweet peas

We are getting ourselves confused again over the common name 'sweet pea'. The last two posts appear to be discussions Pisum sativum the edible vegetable pea. The OP may be asking about Lathyrus odoratus, grown solely for their flowers and not only not eaten but actually toxic. Or possibly the OP him/herself is mixing up the two. The words 'just wanted them for the blooms' would be redundant if referring to Lathyrus since that is their only purpose in a garden.

Sweet Peas(Lathyrus) grow well in the UK climate because of the slow and gradual increase in temperatures and the low maximum temps. I sow mine in January indoors. You could try starting yours even earlier indoors. That way you might have them advanced enough to bloom before the summer heat gets them.

Yes I just mean the sweet pea for that are generally grown for flowers, not for eating. Thanks!
