How to Grow

How to grow video guide
From seed

Choose a sunny or part-shade spot in your garden, protected from the hot afternoon sun.

Loosen the soil and enrich with plant food.

Sow seeds directly or plant in trays of seed raising mix.

Allow seeds to grow 7cm tall before transplanting.

From seedling

If growing from crowns, plant so that the roots are under the soil, but the 'eye' (from where the shoots will emerge) is at ground level.

In a pot

Choose a pot at least 50cm wide and deep.

Position in sunny or part-shade spot, protected from the hot afternoon sun.

Fill starter trays with seed raising mix, and pots with quality potting mix.

Follow seed-> seedling -> harvest guide.

Ready to harvest

Wait until the second year of the rhubarb plant before harvesting.

Harvest by pulling stalks away from the main stem.

Don't cut them as exposed stems can cause rot.

Continually harvest to promote new growth, and remove any flower stalks.

Collect seed

The flowers will turn into green seeds and then eventually these seeds and the entire rhubarb branch (as a whole) will dry out and turn brown.

This is when to harvest seeds from rhubarb.

Saving rhubarb seedpods is easy.

Clip the stalks with snips or break the brittle branches off by hand.

Tips for Care

looks_one
Leave the youngest stalks at the centre of each plant to promote new growth.
looks_two
Rhubarb leaves and roots are poisonous and should be discarded or composted
looks_3
After about four or five years, break up the established clump and spread to new, well-prepared parts of the garden.

The best time to divide the plant like this is in Winter.
looks_4
Stalks don't always develop red stems, but green stems are safe to eat and the flavour is just as good.

Stems tend to develop stronger red colouring in cooler climates.
looks_5
In winter, loosen soil around the plants and fork in plant food.

This will give them a good start for spring growth.
