My Maui onions are growing up. For reference, you can see below what they looked like about two months ago. Planted as seedlings, if that is the right word for them, they are now filling out well.
For the record, the confession: this is my third year of trying to grow Maui onions here in southern California and the first they've survived this long. I can't tell you what has changed although I've acquired a few basic gardening skills over the years, silly little things such as I fertilize the soil before planting, make sure plants get the amount of sun they need meaning not too little not too much, avoid overwatering, and always always always.... mulch.
The biggest change I think has been the mulching. I use generous amounts of dried alfalfa with each planting or sowing of seed. And I suspect this has transformed my garden; I've got happier plants, happier germination rates, fewer weeds, a more aesthetically defined garden, and I conserve water, all at the same time. Great stuff, this mulch.
