Sweet Pea Problems

Can anyone help? My sweet peas started to bloom last week, but these leave last at the bottom have started to discolour and become brittle. They are in home-made planters with drainage holes. I water them every morning. 


  • They are flowering nicely!

    You need to cut the blooms and take them indoors as this promotes new flowers. Maybe this is why the leaves are getting old as they think that all is over. Not sure but that it what we do with our sweet peas and it does seem to work and keep the flowering going for a long time.

    I don’t see any problem with your sweet peas at all ,just keep the blooms picked and they’ll flower on for a few weeks. Sweet peas are grown for the blooms the leaves are never very lovely I’ve found .

    They need a lot of food and water, and a decent hearty soil, preferably with some manure, to grow well and thrive for a long time. The containers don't look as if they have much room for that, and they'll be short lived, regardless of the amount you water - because there isn't enough growing medium to sustain the plants long term. 
    The leaves will tend to be tatty as the plants mature. Deadheading/picking will help with the production of more flowers, but the secret to good sweet peas is what you do at the start  :)

    I meant to add- if you have them in a sunny site, and you're in a hotter part of the country, try growing them in a shadier spot. All the info tends to say full sun, but in extreme heat, they really struggle, unless in the ground and in really good growing conditions.  :)
    In containers, even long periods of heat that isn't too extreme, can be difficult for their ongoing health. I grow a lot of mine in semi shade, and we don't have the high temps here that many places have.

  • This happens to my container grown ones too. I’ve learned to live with it by putting a row of window boxes in front with lower growing plants, makes for a pretty appearance of a “flower bed”, hides the ugly bits and stops the sweet peas having to compete with anything in the same soil.
    Marne la vallée, basically just outside Paris 🇫🇷, but definitely Scottish at heart.
