Alstroemeria ligtu seedlings

Roy, I would recommend putting them in very deep pots. They love to go
down,down,down. When they first come up again, I would recommend
pulling them out. It sounds cruel and unusual punshment, but they seem
to develop much sturdier underpinnings if given this treatment in Pebble
Beach, at least. You won't get the whole plant when you pull, so don't
worry about that. If you do find yourself with no plants because of my
advice, call and I'll send you some replacements. Nothing special, but
Alstroemeria ligtu plants for sure.

Dear experts,

I am a novice Alstroemeria grower. Having successfully
germinated several dozen Ligtu hybrids from seed some
months ago, I am now witnessing a withering and dying
back of all of my seedlings. A couple of inches of
height, with a remarkably large root, they are now, I
reckon, following the seasonal decline that my fully
mature Alstroemerias (bought in pots) are going
through.

The young plants are mostly in three-inch pots. How
should I handle the next phase of their existence?
Pull up roots? Transplant now into my San Francisco
foggy garden? Leave pots alone?

Many thanks for your advice.

Yours,
Sam Gilbert

Sam: I've done lots of ligtu transplants from seedlings and been
where you are now.

You can leave the seedlings in the pot for another few months or
transplant them now; note that the roots you see are fleshy roots,
not the fibrous ones required for good rhizome growth. The important
thing to see is that the one to 3 fleshy roots are joined to a very
small rhizome and probably everything has to be handled gently to
keep the seedlings from falling apart.

By gently I don't mean using kid gloves, just avoiding a lot of
torque or bouncing around.

The biggest problem with growing alstroemeria in San Francisco is
finding a spot with enough sun, just the opposite of what I run into
in Davis. Ligtus are very hardy in my experience and can tolerate a
lot of heat and cold.

Please write if you have other questions.

Roy
