Hi, I planted rocket seeds in a large pot with organic soil about 3 months ago. They sprouted very quickly then when they were about 1 centimetre they went purplish colour. Now 3 months later they are only about 2 cms high!!! (In another pot (about 3 months ago) using the same soil I planted seeds from same pack - these grew to about 2 inches and didn't go purple. BUT they haven't grow anymore!!) I tried everything, not watering, watering, adding fertiliser, leaving them in constant hot sun, not so hot sun...but the purply ones have not budged!! I took one out and the roots are about 4 inches long though... I am wondering if I should just start again?? Thanks anyone who can help!!

Same thing happened to me they grew to a small size and stopped growing, my issue was over watering. Now I use a moisture meter about $10-$20 from large hardware shops . And they do very well. Also Liquid feed fish/seaweed every 2 weeks. Try digging out a bit of soil down to the bottom of your container and see if it is water logged?

Thanks Helga, I think you are right - the pot i used didn't have good drainage (i now know)!! Will give it another go... thanks again

My rocket has flowered and begun to make seed pods, despite me trying to cut off the flowers. Do I need to dry out the seed pods before attempting to replant them, or just pop the green seed back in the soil?
28 Dec 10, Jim (Australia - temperate climate)
I think drying the seed is best. I pick the stems with the pods attached and let them dry out for a week or two - the pods crack open then and the seed falls out easily. I then dry the seed for a week or two and replant as and when required. If you are keeping seed it will certainly need to be dry or it will just rot. As for planting green seed I've never tried it so??? The seeds need to be fully developed so I would assume this is when they are pretty much dry.

here in cool climate Australia I simply let the plant go to seed and am never without rocket.... Not sure if this is possible in your tropical part of Australia? Maybe give it a go.....

Is Rocket healthy and if yes in what way?
21 Jan 11, (Australia - cool/mountain climate)
Yes healthy, raw in salads, raw into sandwiches, bigger, older stems throw into stirfry dish just at the end, as it doesn't need a lot of cooking... OR juicing with everything else green from your food garden... good health Jen

I am a first time gardener. I planted rocket 2 weeks ago and have had a great response. However, I planted several seeds in each hole, so now have clumps of seedlings (about 2 cms high). Do I need to thin them out or separate them or can they grow together as is? Please help - I love my rocket!

Yes they grow so well. Dont worry just leve them as it is.... dont try to seperate..put potty mix and water well.... .. when you remove one day...take the whole bunch off...or take off leaves as and when necessary...good luck...
