Is rhubarb ready to eat when the stalks are still green? Our plant is a few months old.

Just wondering if it is possible to grow rhubarb in a large container, we have downsized and are short on space? TIA

Hi, Rhubarb does great in containers. I've had one for years as an ornamental.

You could do it. It would take a lot of looking after. A suggestion, buy a 200lt drum, cut it in half, put some holes in the bottom for drainage. Plastic 200lt drum on Facebook - market place.

Best planting option soil sun and watering please. Desperate to get a plant growing healthy for rhubarb crumble

Start with good rich soil, 6-8 hrs sunlight a day, and water 3 times a week. Read the notes here first.

It is really better to grow rhubarb in the ground as you don't want the roots to 'cook'. If the tub is large and not exposed to direct heat it should grow OK. When potting up any vegetable in tubs it is a good idea to line the bottom of the tub with nespaper, old jeans or other cotton clothing. Baby nappies with the elastic, etc trimmed off are also ideal as the crystals will hold a lot of water as a reservoir for your plants. Rhubarb likes a lot of manure so a generous amount of pelletised organic fertiliser, cow manure or blood and bone is beneficial. Mulch the plants with lawn clippings or something similar as this will help retain moisture. trust this helps.
