My rhubarb has healthy leaves but very short stems. How can I encourage the stems to grow much longer?

I planted new Rhubarb in the ground and used old poultry manure to feed them, it took two seasons for the plants to grow large stems. If you have new plants it will take a few seasons for them to do much better. Water daily and good luck

is it best to snap the stems of or snip them

Pull them off at the base of the stalk. If you cut them, it leaves an open 'wound' for disease to get into the rhubarb plant.

We have rhubarb growing but the stems are large but still green how long before the turn pink so we can pick them?

Hello Greig, AS a lot of rhubarb is grown from seed it can be very variable in stem colour. I understand greenish stems are just as flavourful but less appealing. put a little bit of cochineal (red food colouring) or raspberry cordial in the pot when you are cooking it to enhance the appearance. trust this helps.

There is a variety of rhubarb that has green stems and it actually is milder than the red stem variety. So pick and enjoy.

Gold Coast here.. Usually my rhubarb carks it after 12 mths or so.. doesn't like sea level humidity. When I cook the green stem varieties, I simply add a drop of cochineal once cooled down to change colour to the red..(which is more attractive.)

Go for trays. I have never heard of rhubarb by seed always corm. In trays at least you can keep an eye on it and know what is happening throwing seed into the soil sometimes is taking too much of a chance with birds, mice, rotting etc..especially with odd things like this.
