Could I suggest you repost your question here- David has started a sweet pea thread and it would be nice to have all the questions and answers in one place to help other posters?

sweet pea queries


Exactly what I was going to say I reckon David k knows everything you need to know about sweet peas


Told you he was your man nothing he doesnt know about sweetpeas.

My sweatpeas have not fllowered yet!  The leaves at the bottom are patchy and yellowy-brown plus some of them are a bit holey!  Maybe I've overwatered them?  Our soil is clay so it holds the moisture so maybe I didn't need to water them as often as I did.  Will they still flower do you think?


Will yellowed sweetpeas recover from overwatering? !

Thank you

Mine don't look too good at all and have hardly grown.


Rachel - it does depend on how wet and soggy they got, but this warm dry weather should help.  

Lily, how long have they been planted out?  If I remember correctly it wasn't too long ago?  They're probably getting their root system developed - mine have been out a while and are just starting to really grow now.

Hi Dove, not exactly sure....meant to note plant out date in my little book, but didn't ?...but 3/4wks They are no taller then when i planted.

Thank you Dovefromabove !!    I am new to this gardening malarchy and on sandy soil, I was told it would get dry very quickly but in this case clearly not !! 

I have my fingers crossed for the poor things ! 

Good luck with yours Star gaze lily ! 

I have just over 300 sweet pea plants started at ditterent times, this year they have taken quite a time to get established, but now they are away. The first sowing at Christmas are now two feet tall and showing their first flower buds, the second and third sowing are fast catching up, the second sowing are on heavy clay ground, the third sowing are on my allotment which is very stony, the first sowing were potted up into large 2'-0" pots 6 plants to a pot, i always try for some early flowers, my wife does the tying up and removing all the tendrils almost on a daily basis, this produces better flowers.


Hi all,

Sorry if I'm repeating anything (first time poster) but it's been advised that sweet peas dont need to be watered every day - but how often should they be watered?  At the moment, we are experiencing pretty warm days (averaging 22-24 degrees this past week)...  How often should I water in these types of temperatures?

Thanks so much,




I have planted out my sweet peas but have noticed one pot have got significant yellowing plants in the centre of the pot.  I have fed them and some flowers have appeared. What is going wrong with the yellowing plants?

You dont say when you planted out your sweet peas; mine are now at the top of eight foot canes and apart from keeping ourselves supplied with flowers we have given 30 bunches away to neighbours; I will admit I am growing 300 plants.  Sweet peas like a lot of water when growing, rain water if possible, if they start to dry out the leaves start to get parched, this also happens if they get wind scorched. You can try an high nitrogen fertilizer to start to see if the leaves change then move on to a phoshate one to encourage flowers.  Good luck


I went away for 7 days during the heatwave in London and now they do not look good - bottom 1/3 yellow, and flowers and stalks very small and not worth putting in vases. I have watered every day in this heat and they are in full sun. Should I let it go? Or is there any other advice?

Many thanks!


Once plants (of any kind) dry out, it can be hard to rehydrate them. Sweet peas need a lot of water and food. When you water, make sure you do it throughly, then leave for a few days unless they look a bit limp. Remove any dead foliage, give them a really thorough soaking now, until the ground is properly dampened to a good depth, and take a look at them tomorrow and see if they've perked up. If they still look limp, water again.  A liquid feed every so often if they've been flowering for a while is beneficial. All annuals eventually run out of steam and need a bit of help along the way. 

If they're in pots, soak them thoroughly with a hose until the soil/compost is throughly damp. The next day, water again with some tomato food to replace the nutrients which will be washed away by the watering. After that, don't let them get dried out and limp. They actually don't like desperately hot weather - they perform better if they get reasonable sun, but a bit of protection from it at the hottest part of the day. In pots, you can always move them to a shadier spot to protect them a bit. 

If you plant into the ground, always try and prepare the ground well with some decent compost and some well rotted manure if you have it. That will get them off to a good start, and will also help if there's a dry spell as it will help with moisture retention. 

Thanks so much Fairygirl.

My garden has very little shade, and they are in a large pot but maybe I planted too many in there, too. It's my first time :)  They started to flower really well just before i left and I was filling little jugs with gorgeous-scented flowers. I'm a bit heartbroken but gardening (as my Mother tells me) is a learning curve. I'm 45....:)
