Sweet Pea

[grandfatherd]

I have 2 trays of the above which have been left too long in the trays, the plants are aprox. 4inch. tall. the SPs. are just showing the first leaf. Can anyone tell me at what depth I should plant them and whether they should be al
all right if planted out in the garden or planted on?
Thankyou in advance DANNY

There is very little that you should be planting outside now and sweet peas are not one of them. We are about to get a severe change in the weather and it will kill them.
Sweet peas are usually grown new from seed, each year. Dont waste your time trying to save a plant that is already leggy and stressed. Get some new seed and new compost and sit tight until the spring. Tip the whole tray into your compost and reuse the tray.
