I've been growing horseradish in a container for about 7 or 8 years now (it especially loves being in the self-watering container). I've been growing wasabi in a (non-self-watering) container for 2 years. Both do just fine -- surviving thru' the winter, putting out a fantastic amount of leaves every year -- except where one thing is concerned: actually producing roots that are big enough to be used for cooking. On the horseradish i get super skinny roots that don't leave much leftover after peeling, and the wasabi hasn't put out any usable roots at all.
Any suggestions? I'm thinking that the 1st obvious thing to try is changing the dirt, but i'm not sure what sort of change to make.
Where did you buy wasabi roots? I've never seen it offered for sale.
I ordered mine from Raintree Nursery: https://www.raintreenursery.com/Wasabi4Inch_Pot.html
I got them 2 years ago and they've done well, as far as surviving. I live in Seattle and garden on a balcony.
Are they getting full sun? Building up an eating root takes more sun than leaves do.
This is a good reminder that i should make sure the horseradish is in full sun -- right now it's behind the Japanese cucumber, which in another month or so will be blocking the horseradish's sun (i garden on a balcony -- it's pretty tight quarters out there). But the wasabi is specifically recommended for shade/partial-sun.
