Hi all,

Appreciate some helps with my ginger plants.
Just started my garden a month ago & I had this ginger plant (still young; less than 1 foot high).
Lately, notice yellow spots on the leaves.
Not sure if it's due to bugs or lack of nutrients.

Appreciate some advices.

is this a new garden? If it is you need to do a lot of work by improving on the soil texture first we explore nutrient problem or pest. Alpinas seldom has insect problem.

Hi DG,

I cut away the yellow spots leaves & added compost to the plants per your suggestion; the plants is doing OK now.
Grown slightly a few cm higher now.
Pls see the latest pic of ginger plants.

If you see underneath the plants, I added a lot of dead leaves & the whitish stuff is actually soya bean residues.

Ginger loves a sheltered spot, filtered sunlight, warm weather, humidity, and rich, moist soil.
What ginger can't stand is frost, direct sun, strong winds, and soggy, waterlogged soil.
Whether you grow your ginger root in a pot or in the ground, you do need really good soil to start with. It needs to be rich enough to feed your ginger (you can always add some fertilizer, see below), it needs to hold enough moisture so it doesn't dry out, but it needs to be free draining so the ginger roots don't become water logged.
Good compost is of course ideal. I use a mix of one part of my best compost with one part of my sandy garden soil. The compost supplies the nutrition and holds water, and the sand/loam makes sure the mix drains freely.
If your garden has reasonable soil just dig in some compost and that should be good enough. If your soil is too heavy you can make a raised bed or a small hill or ridge to improve drainage.
As i can see from the picture you growing in ground you need to mulch it more thickly.

Your ginger plant is looking very nice. I grow mine in tubs, so I put in fresh compost mix every year and never add any extra fertilizer. If your soil is rich then you too don't need to add anything extra. Work in some organic slow release fertilizer, you can use some liquid fertilizer like seaweed extract or fish fertilizer every few weeks.

Your ginger plant will be ready for harvest in the spring, or you can let it grow through the next summer for a larger harvest. The best time to harvest ginger is any time after the leaves have died down. Usually it takes eight to ten months to get to that point. When you are ready to harvest, lift the ginger plant gently from the soil. If you would like to continue grow ginger root, break off a part of the ginger root that has foliage and carefully replant it. The rest of the ginger root can be used as your harvest. Break off the foliage and wash the ginger root. The ginger root can be broken into smaller pieces for easier use.

hi Shirley,

Thanks for the compliments.
I guess my subject is slightly misleading.

This is not not the edible ginger plants; it's a flowering ginger plant by the name of Alpinia.
It hasn't flower so I'm not too sure if it's a red Alpinia or what.
Will keep you guys posted when it flowers (might be a long wait).

I have 2 edible ginger plants in my garden; use for cooking.
1. Lengkuas (Blue ginger/ Galangal)

2. Kunyit (Tumeric)
