Stunted sweet pea flower buds

Mary370Mary370 Limerick, Ireland Posts: 2,003

This is my first year growing sweet peas in pots.  They have gotten some wind burn(?) A lot of the flowering buds are minuscule, why would this be happening?  These were sown in Spring, the Autumn sown plants which were planted into the ground are doing fine.  All seeds were from the same packet.

Thanks

    That could be aphid damage, check around the buds for little bugs (green fly, black fly white fly and so on!).  You can rub these off by hand, squirt water on them and/or put spiders on the plants to gobble them up.

    Sometimes, if the pot is too small, or not tall enough, your plant may be struggling to produce flowers. Do you feed them? If they are grown in a pot, they will need a lot of watering and feeding.

    I have the same problem Mary.
    I grow s.peas in a big pot and in the border.
    Ones in the border -

    In the 25 litre pot-

    The ones in the pot have buds that have started to form, then failed just leaving papery shells.
    I grow them this way most years, never had a similar problem before. 
    They are being fed weekly (tomorite) and in a sheltered southerly position. No sign of aphids or any other bugs

    Knowledge is knowing that a tomato is a fruit.
    Wisdom is not putting it in a fruit salad.

    It's very frustrating, think in future I'll just plant them all in the ground.

    Thanks Mary.
    I grow them successfully in the same pot and position each year. The only variable I can think of is the weather.
    I'll persist with them and hope they come good.

    I'm definitely no expert on sweet peas (or anything else for that matter) but could it be bud drop caused by changes in weather conditions?  

    If it changes from very warm to wet and windy like it has done in my neck if the woods, this is the result  -  I've got the same problem ?

    I suspect you're right. The temperature swings recently have been crazy. 34c last week (47c in the g/h!) and 16c today.
    I also have a vague recollection that they shouldn't be watered in the evening if it's chilly - I don't think I have. So I'll see how they go

    They also recommended not watering with very cold water?? If using hosepipe let it warm up a but before watering ?
