I bought Rhubarb plants from Bunnings about 3 months ago, very small and delicate, and they just don't progress. Each time it is windy, or we have a warm day, they seem to wilt and die off. They are in red soil, with horse manure mixed in, and the ph is about 8-9 I think(it's difficult to tell the colour of my PH test kit), sun from 7am till 2pm, and mulched with sugar cane mulch. So much for rhubarb being easy to grow :-( .Anyone got any suggestions?

I also bought a Rhubarb plant from Bunnings, but live in Sydney. The horticulturist there advised me to plant in a big pot about 45cm plus. I mixed coir, mushroom compost, sheep manure and soil and some complete manure, before transplanting. Water once a week with Seasol and water in between. I don't water everyday as have mulched with sugarcane, it gives the plant time to adjust or they become water dependent. Also leave the pot in part shade until the plant grows vigorous. Haven't had any problems so far, expect to leave the rhubarb plant in your pot for at least a couple of years. I use manure pellets to top up my plants every six months, it seems to keep them healthy. Hope this helps.

We live in Toowoomba and I have 3 plants also very young. They get quite a lot of sun and it has been warm here recently,they are growing but very slowly and they did drop back a bit after planting them into a raised bed.I do water them 2-3 times a week ATM and they are doing OK. Not much help I know but just thought I would share.

I put in new rhubarb plants in autumn this year and they are growing really well. When should i harvest them and can we eat them this year? TIA

Hi. I have a number of plants, from very young to quite established, and harvest stalks from the outside of the growing area any time they are big enough. Just pull away from the centre, leaving the central part where new leaves/stalks will form. If the plant is young, the stalks will be thin and won't get thicker if you leave them on the plant, where they will just soften and wilt. Hope this helps. Happy harvesting!

How do I keep my rhubarb stalks red?

it is October and I already have long, thick stems on my plants. Are they ok to eat green? Also, it looks like it is starting to flower. What does this mean? Thank you

I find my plant is a black stump in the long frosty season, but now September it is happy. My question please is- do I need to wire it over in the bush to protect it from the roos or other critters?
