(Best months for planting Silverbeet in New Zealand - cool/mountain regions)


  • Easy to grow.
  • Harvest in 50-85 days
  • Sow in garden. Sow seed at a depth approximately three times the diameter of the seed.
  • Best planted at soil temperatures between 10°C and 30°C.
  • Space plants: 15-30cm

Edible dark green glossy leaves with wide white or cream stalks produced over a long period. Both leaves and stalks are eaten. This is a cut and come again plant, providing leaves for some months before going to flower. Can re-sprout from around the base if cut off when it starts to flower.

Reasonably frost and heat tolerant. Grows well in most soils. For prolific growth apply compost, or well-rotted manure. Resistant to most plant diseases.

Culinary hints - cooking and eating Silverbeet

Wash thoroughly and inspect the back of the leaves for insects.
Chop and put in a saucepan with very little water ( or just what is on the leaves)
Cover and cook over a low to medium heat until the leaves collapse.
A small amount of nutmeg enhances the flavour.

Hi all. I too am a complete gardening noob but learning very quickly :) I planted my seedlings about a month ago and were growing really well until I moved them to the other side of the raised planter box a couple of days ago. Now they seem to be wilting and I'm not sure why. I'm pretty sure the roots kept intact. I did put a little general fertiliser in the ground on the move. It might be from the extra sunlight they're getting. They're getting watered at least once a day. I watered them at the end of one day and they perked up a little. Any tips? Cheers, Benet

My silverbeet are healthy and they taste good but the leaves are not dark green - more a spinach green colour. I planted seedlings from the garden store Ironman variety - the soil is friable and well composted. Please advise what I am doing wrong - they get full daylight but direct bright sun afternoon only.

Patrick - not sure if you have worked out your problem yet but sounds like powdery mildew - you get this in hot dry conditions. Does that sound right? I don't do much about it myself because it is a minor problem for me - but there are lots of possible options - have a look online.

I'm a novice gardener just trying out planting silverbeet. I used compost in the soil and they grew really we'll for about 2 months. Now, in Jan, with very hot weather, the silverbeet are somewhat reluctant to grow. I have been harvesting almost daily, about 5-6 leaves per day from the plants. Is this bad? Also, some of the seedlings aren't taking off very well. Any ideas? Thanks.

first -- mangold is NOT the same as silverbeet, it is a kind of large beetroot grown for animal feed. Silverbeet's other common name is Swiss chard, often heard used in North America and UK. Second -- it is worth noting that small quantities of agricultural salt are applied when growing Beta vulgaris crops for fodder on farms, and also that silverbeet grows very well close to the sea, often as a garden escape, eg there is lots of it in various bays around Banks peninsula. This may suggest that in inland places it would benefit from a tiny feed of salt water -- but be careful not to overdo it. Thirdly, it is worth knowing that the tops of beetroot are very similar to silverbeet. Don't waste them! Of course the older and yellowing leaves are no good but bright green vigorous ones are excellent. I have been using leaves off Yates Baby Beets and I think if anything they are even better than silver beet.

Ahi- Watering every evening will help if they have a dry spell they tend to go to seed. Aliquid feed eg seaweed and fish should help their growth. My silverbeet have slowed down due to heat. When removing leaves take the whole leaf stem aswell :)

hi, im still learning how to grow and develop my vege garden this season my silverbeat grew very big bushes which was great to see but it one bush has a mould like cover on it, does not wipe off? any help tips please

Louise, It sounds like mildew on your plant. The best option is to remove it completely. Don't compost it , burn or bury it away from your vege garden.
