Not recommended for growing in New Zealand - cool/mountain regions

  • Plant pieces of fresh root showing signs of shoots. Best planted at soil temperatures between 68°F and 86°F. (Show °C/cm)
  • Space plants: 6 inches apart
  • Harvest in approximately 25 weeks. Reduce water as plant dies back to encourage rhizome growth.
  • Compatible with (can grow beside): Grow in separate bed
  • Ginger plant
  • Ginger ready to harvest
  • Ginger root
  • New shoots of ginger

Ginger is a warm climate plant. It can be grown indoors in pots in cool/temperate areas. To grow well it needs lots of water and nutrients. Prepare the soil by adding compost which will retain some moisture but not get saturated. Add a small amount of sand to ensure drainage. Water regularly in summer to keep moist. In a pot, in addition to watering to keep moist, water ginger about once a fortnight with a seaweed or other liquid fertilizer. This perennial will die down in autumn. Remove the dead leaves. In spring lift the root clumps and break them up into smaller pieces to replant.

Harvesting Ginger: You can harvest ginger root after the plant dies down in winter, digging around the plant to cut off a piece of the older root. The young root with shoots is the actively growing plant and should be left to resprout.

You can also carefully dig down under the plant through the growing season to cut off bits of the older root for use, just be careful not to disturb the rest of the plant too much.

Let plants become well established before harvesting - it is often best to wait until the second growing season.

Make sure that you have edible ginger. Ginger plants sold in nurseries are usually decorative varieties and not suitable for eating.

Ginger can be grown in pots. The best growing temperature is around 25 - 30 C (75 - 85 F)

Culinary hints - cooking and eating Ginger

Ginger root freezes well either whole or grated, and can be used direct from the freezer in most recipes requiring fresh ginger.

My ginger was growing well after getting a piece of my neighbours established plant. We have had a very wet winter and after dieing right back it has not resprouted. Neither had the neighbours. Did the wet do this? Should I lift the bulbs and replant it?

After the harvest season, can ginger be left in the ground for following season of growth?

Gardenate does not suggest growing ginger in NZ temperate climates, maybe not warm enough. If you are going to try to grow it read the notes here, your answer is in the notes.

I had a piece of ginger which began to sprout so planted it for fun and grew on a window sill in our shed. It got to about 2 feet tall so I dug it up and got some juicy little corms or bulbs or whatever, which tasted lovely.

Do you have to wait till the top has died down before harvesting? I'm not sure what to do as there is some older growth but one new stalk has come through.

Young ginger will taste mild while old ginger will taste more fiery. When you harvest your ginger root, was it the 'young' or 'old' part of the root?

Hi! I live in Newcastle too! I know u mentioned u wanted heirloom ginger (I’m not sure u will get “Heirloom” ginger as such-there are several different varieties of edible ginger though). I just bought mine from the supermarket (if u wanted, u could look for organic ginger in supermarket/farmers market etc.) with signs of tiny shoots (u want to make sure of this as sometimes they can be treated with chemicals that prevent shooting-although it seems producers are not using these chemicals as much these days). If u didn’t want to go the supermarket route, u could try Daleys Fruit Tree Nursery (Kyogle, NSW-they have a mail order service & lots of unusual/rare/interesting fruit/herb/spice plants-I find it near impossible not to buy something when I visit the site!). I’m fairly sure greenharvest.com.au has them. Diggers (Dromana, VIC) may also be another possibility. I just did a quick search “buy edible ginger NSW Australia” & got several hits. I left the rhizome out of the soil for a couple of weeks to let the shoots develop more, then planted it. I would buy your ginger a couple of weeks prior to the beginning of spring so it has time to shoot before planting in early spring, as ginger dies back a couple of weeks into winter in Newcastle. You could bring your plant inside for winter if it’s a possibility for you, as it would allow continuous growth-I would probably have a pretty impressive plant by now if I was able to bring mine inside, as Newcastle winters make the plant completely dormant & slows its growth significantly with it having to “come back” each year. Make sure u water minimally over winter, or your rhizome will rot & not reshoot. I wish I had known that ginger dies back in winter here early on, as my first planting died because I planted it in the middle of summer. It just didn’t get enough growth on to make it through the winter and reshoot! I also suggest you don’t harvest it for at least a couple of years, to get the plant really established (as it takes a LOT out of the plant to reshoot each year). I’ve had mine for about 3 years, & it’s successfully “come back” after 2 winters now. I haven’t harvested anything yet, and don’t plan to for another year or so, just to make sure. I grow mine in a big pot, & it’s quite happy in partial shade (I live in a block of flats). Recently, I saw a YouTube video describing a different method of growing ginger that results in better/quicker production-I think I’m going to give it a go! I think I would start this process around mid winter, so plants have spring/summer to get going before winter. 1. Place the rhizome in a container of moist soil, just barely covered (you still need to be able to see the tuber and what it’s doing) 2. Let it shoot. 3. When the shoots are at least a couple of centimetres long(the bigger the better), the base of the shoot should have a bulbous appearance (yellowish in colour) with little bumps on it that will become roots. 4. When there is a decent number of bumps/developing roots, break this off the rhizome (it should break off easily), and plant so the bulbous part of the shoot is well covered (at least 3cm deep-but depends on size of shoot). Don’t plant too deep, or the shoot could rot. You can always add more soil as the shoot grows to ensure the tuber is well covered. 5. Replant the rhizome and wait for the next shoot, repeating the process until the rhizome doesn’t produce anymore shoots. I would probably try planting the “mother” rhizome as well, as u have nothing to loose-it may grow as well! You could buy several rhizomes at the same time & follow this method-it would result in more plants, just in case some don’t make it through their first winter. Apparently this is a method that many commercial growers use for higher/faster production. Goodluck!!!
