GREED is not good when it comes to rhubarb - you need a little patience.
Pot-grown rhubarb can be planted at any time, in an open, sunny site with free-draining soil.
With crowns, plant late autumn-early winter. You can plant later, but run the risk of crown rot.
If you planted new crowns in autumn, don't harvest during the first year.
Remove a few stems the next year, then up to a third or half from then on.
It's best to stop cropping by June (unless you have an autumn-cropping cultivar), or at least only remove a few stalks after then - older varieties often go stringy then and the plant needs the sustenance.
Keep rhubarb free of weeds by mulching with composted manure, but avoid burying the crown as it will rot. Give plants 100g per sq m of Growmore in March and water regularly in dry spells.
When the top growth dies back in autumn, remove the dead leaves to expose the crown to frost - this will ensure a good crop the following year.
A word of warning - only the stems of rhubarb are edible. The leaves contain toxic oxalic acid - cut off the leaves and add them to your compost heap - they will rot down safely there.
IF you can’t wait until April for your first crops, try forcing an established plant.
In January, cover the crown with straw and place a large bucket over the top to exclude light - or use a traditional terracotta forcer (pictured).
The pale pink, tender stems can be harvested about eight weeks after covering. Don't force the same crown for two years in a row, as it weakens the plant.
Forcing rhubarb
IS it a bird? Is it a plane? It's the weird buds and leaves of the ornamental rhubarb, Rheum palmatum, after bursting forth in April.
I'd really recommend growing it - it's a talking point. Huge purple leaves, maturing to dark green and purple underneath, evenually reaching to about 7ft tall with an even-bigger flower spike.
The flower stalk is particularly rude in bud - use your imagination.
It's also poisonous - don't think you can eat any of it (ordinary rhubarb leaves are too, containing oxalic acid, a kidney toxin and corrosive acid).
