What’s wrong with my sweet pea plant?

[PickledMuffin]

Its leaves are starting to turn yellow, but it looks like it is going to flower. i don’t want it to die 😩 images will soon load up hopefully.

I'm not a sweetpea expert but my guess is pot much too small. There's simply not enough room for enough roots to support and feed the plant.

@dairydebris is right, your pot is too small. Sweet peas have very large root systems, they need a big deep pot to keep them fed and watered. Repot in fresh compost, in a pot at least 10-12 inch wide, or larger and deeper, give it Tomorite and lots of water. I would also give it a teepee to wrap around instead of a single cane. I make my teepees with three bamboo canes and garden twine, it takes minutes. Keep giving Tomorite to prolong flowering.

thanks for coming back both. I have repotted, fed and watered. i really hope it isn’t too late for it 😞 my daughter planted it from seed 🤞

Good luck! Let us know if it pulls through x

thank you, i’ll do that 🙂

The pot is too small and it needs feeding.

Hi again. I did repot my sweet pea, but unfortunately it looks like it’s died after i went on holiday 😭 however, it does have pea pods. can i use these to grow a new one? If so, what do i need to do with them?

they look quite big?

A couple of things to help - ( apart from the pot issue already dealt with)
in order to keep sweet peas flowering, they need the seed pods removed as soon as the flowers fade. Picking the flowers encourages the plant to produce more. Also snipping off the tendrils helps the flowers bloom.
The seed pods that you have, when it turns brown will have pea seeds in it. You can plant these in pots, the Autumn or wait till next spring. They will need to be kept warn to germinate.
However, sometimes the seeds from plants do not germinate for a variety of reasons, so you could experiment with the ones you have got. I would also buy a fresh packet of seeds for next year.
Its lovely that you and your daughter are planting Sweet Peas.

thanks for coming back. i think it’s dead, will the seed pods still mature?

Not really they need to dry fully on the plant. Try again next year. Gardening is a learning experience, no matter how long you’ve been doing it! Don’t give up, it’s a lovely hobby, especially to share with children.
My sweet peas are also nearly over, they are at their best in May, June and July and are exhausted and finished by August.

My sweetpeas have been very poor this year. I think it’s just been too hot

thanks for the replies, there’s some growing wild by my house and they’ve been doing fine. i think it’s being in the pot that hasn’t helped them. I would like to ideally plant them
in the ground next time when they’re mature enough.
