Why are my sweet peas dying?

Why are my sweet peas dying?
In hot,dry spells sweet peas need lots of water and nutrients. If grown in the garden without water and nutrients the leaves will turn yellow. Grown in a tub (that retains water) they will thrive (in current weather conditions).

Reply:they are a cool weather plant, when it gets to hot they die out,
Reply:Not enough water hun...they need tons of the stuff every day..also..once they start flowering..keep picking then..then you will have flowers blooming all summer!
Reply:Sweet peas love lots of water.
Reply:They need plenty, plenty of water + a good feed, Miracle Grow or similar. If grown in pots, there may be no nutrients left in soil.


Also pick any dead flowers off, to stop them going to seed.
Reply:my sweet peas grow in containers, and they do great. my tricks:


- water well every evening, even if it was raining (check to be sure: soil needs to be moist)


- once a week water with diluted tomato %26amp; veg food


- cut the flowers as soon as all buds on the stem are opened


- sweet pea likes 'head in the sun, feet in the shade', so i planted a mix of lobillia and poppies to cover the base of the plants: it looks great and also helps in keeping the water balance





good luck!

Reply:The problem is not a lack of water or nutrient deficency. I agree with bllnickie, it's a cool weather plant and its gotten to hot for them.
Reply:How hot is your weather? They tend to die out when weather gets hot. Mine are dead by late June. And that is how they die, they go pale and yellow then finally dry out. I always pull mine up and plant a hot weather veggie in its place.
Reply:Perhaps they aren't getting ehough water. Sometimes too much sun makes the leaves go yellow. Are any of your other flowers and plants looking sick? If they are, a pest.disease could be causing the yellow colouring of the leaves.
