Begin thinning your asparagu seedlings 3″-5″ apart. after one year, transplant to a permanent location where the plants can grow undisturbed.

How Much Sunlight is Needed to Grow Asparagus

The amount of sunlight is another key to a successful harvest. Too much sunlight will dry out your asparagus. Not enough sunlight will stunt your its growth or even kill it.

Ideally, the soil should be damp to touch; not soggy or bone dry. If the leaves on your asparagus begin to change colors or start to look droopy, you need to adjust how much water you’re giving it.

Unfortunately, if you give it too much or too little water, you can kill it, so it’s best to just keep an eye on it and water as needed.
