Growing Scarlet Cannas

Cannas like a lot of sun and rich, moist, well drained soil. Shelter from wind is recommended to keep the leaves in top condition.

They are great container plants, where they like to be watered daily in the growing season: do not let the pots stand waterlogged, it is important for the potting medium to have both air and water.
Move the pots into shelter to overwinter and don't water them.

You should deadhead the flower stalks as soon as they fade, and you may choose to prune out the entire shoot at soil level to make room for new shoots - it really depends on whether you want to keep the mature foliage, or encourage new growth.

Brown, mouldy leaves on your canna are not uncommon. Do not use any products against this: simply prune all mature shoots down to ground level, leaving any brand-new shoots that are coming up around the base. Give it a liquid feed, water consistently, and it will recover quickly.

Growing cannas outdoors

In the warm South West, it is usually enough to cover the soil with 15-20cm of mulch to protect the rhizomes in winter.

In most of the UK outside the South West, cannas need to be lifted and stored in barely moist, frost free compost to overwinter. They are planted out again in April-May after the last frost.

It helps to have a cutting tool for the roots when you divide them up, both to divide the clump and to remove excess roots - keep about 6-12 inches, 15-30cm.
Trim off any green shoots before storing the rhizomes in a plastic bag with moss in a cool dark place.

Cannas in most borders should be watered every 2 to 3 days in the growing season.
