Cherry trees and nasturtium - are they good companions?

Hello everybody! This year I decided to plant a morello cherry tree, a stella cherry tree and a red leaved dwarf peach tree in pots. I read on google that nasturtium could be a good companion for my trees. So I planted mixed nasturtium round my trees in pots. All plants look very nice but nasturtium is growing like mad. It is huge. In some pots it is about 60 cm high! I started worrying about my trees though they look rather healthy (touch wood). See my pictures. Could anybody advise me if I should leave nasturtium as it is or better cut it down or even to pull it out from the pots?
Thank you in advance for your recommendations.

 

I don't know if nasturtiums are a good companion plant for cherries, but if I growing fruit frees in pots I wouldn't grow anything else in the pot as the competition for water and nutrients might affect the growth of the tree.

 

Thank you all for your recommendations.
Are the nasturtium leaves tasty?

 

No nasturtiums there for me Black Orchid. They make the fruit trees look messy, interefere with the natural branching and growth of the trees and take light from them too.
Nasturiums are weedy things in my opinion....they will seed everywhere; concentrate on growing good fruit trees.

 

Peppery cabbage white caterpillars love them.

 

Hi @Black Orchid ,

I grow Nasturtiums under trees. What you have to go for are the shorter around 6/8" bushy bedding types such as " Salmon Baby " , " Rose Queen " or " Black Velvet " .

Not all Nasturtiums are long gangly climbers/trailers @Verdun .

 

Ha ha, your're right KFF. Not my cup of tea but many love 'em. Just prefer those fruit trees to get all the light, attention and space

 

I suspect that the recommendation came about as Nasturtiums attract blackfly so the thinking goes that they'll lure nasties away from the trees. I'm with NigelJ and Verdun, though..a potted tree needs plenty of water and nutrients, which the Nasturtiums will be using up.
