I have a rhubarb plant which has mainly green stems. I planted it in spring six months ago. It is growing very well but I read that you should not pick stems for the first year or so. Does that mean I leave all the leaves on the plant and wait longer until I cut the stalks or do I cut the leaves off now leaving the corm exposed. I have it well covered in mulch.

I live in Adelaide south Australia my rhubarb grows slow and stunted. the soil is clay based but is worked very well with organic matter,but I still get poor results.how do I solve this problem?

Hi John, I also live in Adelaide and grow rhubarb. Mine grows very well autumn to spring but suffers in summer and goes to seed heavily. I find lots of rooster booster during the growing period and water over summer keeps it growing well, also harvest heavily over the growing months. I am about to do my first cut back and divide of root this winter as I want to reclaim the area I planted and move it to a shaded area for better growing in summer and frost protection in winter. Soil preparation will be 1 part compost 2 parts in place soil heavily dosed with rooster booster. For the first 12 months I will take time to ensure the area will be kept damp all year round until established. Hope that helps.

Is it ok to grow Rhubarb next to my Asparagus bed?

I have read that they are good companions. I am currently dividing my Asparagus and my Rhubarb and they will be in the same bed and planted at recommended spacings of 60 cm.

Have a think about it. Asparagus has a tall fern on it most of the year - do you want it shading the rhubarb?

I found rhubarb in Riebeek West nursery and in Wellington nursery next to the Perfect place. I think it was ringard Victoria. If it's sold in local nurseries I believe they'll be fine in our climate. Mine has been growing for a few weeks now, transplanted in a shade net house and still doing good

Hello, I've just bought another small rhubarb plant(the first one died). i live in Qld and the weather can get to about 38 degrees at this time of year. It gets really dry and hot and the heat easily kills plants. I successfully killed the first one and I don't want to do that again. I've read a lot of different things about growing rhubarb and I'm a bit confused, so I was just wondering what are the ideal conditions for planting rhubarb at this time of year, as well as right up until harvest time? thank you Ashleigh : )

you really are better off putting them in a raised garden bed with mixed clean top soil, lots of compost, peat moss, blood meal, and a slow release fertilizer. Rhubarb get very large and can live for many years and their root systems can get quite large, keeping them in pots will restrict their growth and you will have to water more often and continually use fertilizer more often then them being in the ground.
