Hi all,

This is probably my 5th attempt at establishing Flax plants here in S. California. It's considered drought tolerant so it's on a drip system (plus occasional hand watering). The plant starts out looking great and then eventually the leafs start to shrivel followed by no growth at all. I follow planting directions carefully too.

Any idea how to save this? The weather isn't helping right now (99+ degrees) but I've also planted these in the Spring without success.

Thanks,
Jonathan

I am guessing you mean New Zealand Flax. What I read said hardy in zones 8-9-10 , and needing Winter protection in zone 8. They do better in afternoon shade and need a rich organic mix and to be careful about being in an area that stays wet to long as this causes rot. The original species do better then the hybrids and they do not do well in an area with harsh winds. Hope any of these things help.
Also noticed you are using stone as mulch which can sometimes cook plants in a lot of sun.

Even "drought tolerant" plants need ample water for their first year to establish a strong root system. Your description suggests that you aren't watering them enough. Planting anything in the 99-degree weather is a risky undertaking, even with daily watering and shade protection. If you want to try it again, do it in the spring or fall and give them plenty of water on a regular basis. An average drip system is not adequate for a new planting at first. If a heat wave hits, create some shade during the hottest hours of the day. 40-60% shade cloth works.

I'm trying not to ask why, after the 2nd, 3rd and 4th attempts you haven't considered some other plant, but it sounds like you're determined to grow Phormium. You didn't say what species you have. Have you researched the ones best suited for your climate and conditions?
