Hi Everyone,

I'm new to the site and just trying to find my way around it. I'm about as good with computers as i am with gardening.. and that is not good. Could anyon please tell me why Sweet Pea packets tell you to sow in either April or October? If i sow them now will they flower this year?

Sorry i know this must be a dumb question

On plant Lathyrus odoratus (Sweet Pea)

Hi, and welcome, Sweet Peas are funny old things - you can sow them in Autumn and overwinter them and so get a head start the following year (normally you pinch out the tips to make them bushier) or you can sow them spring time and they will grow fine this year. Depends what sort of space you have - if your window sills are anything like mine its probably easier to sow them in the spring.

I sow mine in October but do have a greenhouse. This just mean you get an early start. If they get leggy you just trim them back which I have done twice now, this then also make them more bushy. I have been hardening mine of all week. So they come out in the morning and then go back into the greenhouse in the evening I have planted some out today but with cold weather still to come I will keep hardening them off and plant more out next week.

They best way to sow sweet peas are in root trainers or the cardboard tubes left over from finished toilet rolls. The reason for this is that sweet peas do not like to be disturb. So sown in tube and them plant out when ready. Once they start to flower keep picking them as this will extend the grown season. They are a thirsty plant and a drop of seaweed food once a week should give you the pleasure of their sweet sent well into later September.

I sowed some in the garden about 3 weeks ago. They are all growing now. I soaked them first as suggested on packets and in books. I'm sure this helps. Here we can't sow in Autumn outside because our winters are too cold, and I don't have much space indoors for overwintering them. I'm sure yours will do well.

Nothing else to add to all the great advice you got from everyone, but just to say there is no such thing as a dumb question!! One of the joys of gardening is learning something new everytime you do anything with your plot.

Hi sweetpea ~ Welcome to the group. Although I know computers, I sure don't know gardening and these people in here have been just wonderful. Very helpful without making you feel stupid.

Hi like you I'm new to gardening and GOY and have the same question as you did.
How did you do with your Sweet peas? I am still trying to decide if to start them now or wait till April.
I was looking to see if you had put a photo of them on GOY.
Hope you had a good display.
