I've grown sweet peas for a number of years. This year the stems were very long initially but have got shorter each picking so now they will fit into an egg cup.
I planted them in well manured slightly alkaline soil mixed with multipurpose compost in a sunny position in the garden.
I can't remember such consistently short stems. Is it the variety?
Mine do the same. They did it last year with lots of water, and this year with less. I give them a feed, dead head everything, and they picked up.
Mine are doing the same Sheila, nice long stems for a few weeks, picked loads of them and the stems on new flowers are growing shorter than the initial ones. Not sure why.
Same here. Would really like to know why!
I am also having the exact same problem! Not a great year for my sweet peas compared to last year
