I know its been mentioned a few times, but what is the optimum temp for a meyer lemon in the root zone. I put my meyer through a lot, and I'm trying to make him as happy as possible. right now hes on a heating pad, around 65-70F (hoping thats ot too hot) Just doing what I can to keep him healthy as I can. Besides the heating pad, I also have it under a grow lamp. I know in transplanting I damaged the roots plus stressed him out further by putting him in a too hot of room (compaired to what he was used to)

any other tips suggestions would be great. All my othertrees are doing really good

It depends on the type of root growth you wish from your Meyer Lemon. The very optimum temperature for root growth (elongation) is obtained at 80.6F (27.9C). If you want optimum growth of the root hairs, which absorb water and nutrients from the soil, then the optimum temperature is 93.2F (34C). Note that at temperatures of 98.7F (37.05C) and above all root growth completely stops. - Millet

I'm just wanting the best root growth to get the health of the plant back. I didn't realize how badly I hurt the roots when I transplanted until I dumped out the old pot. there was a fist size clump of roots.. I dont understand how it happened, the whole root ball came out easily, obviously not as easy as I thought

So it looks like they'd be happiest at a bit of a higher temp. I want to get the root mass growing to help support the upper and get growth happening again. It just looks so incredibly bare, it scares me. I dont want it to die. It was the one plant I paid most for, the one that looked the healthiest... but looking back, it wasn't. it just had a ton of blooms and once those were gone, I could see the lack of leaves

I just hope that I can get it back... I know that once the weather gets warm, the nice bright sun really should help. so.. heres to hoping!

I'm wondering if those roots were already dead from root rot. Or, the soil was too wet & heavy, & that clump of roots was stuck to a heavy, wet clump of soil when you dumped it causing it to fall away & took those roots along. Just a thought.
Keep it out of direct sun.

I dont think it was root rot or anything. All the roots looked very healthy. even the clump that I found in the pot. Might have to go back and look, but then again its been so long it'd be hard to tell.

With root rot, could the ends be healthy, a spot of root rot then the other area healthy? that could explain how it seperated? Maybe I'm grasping

I have it away from the sun. its under a grow light and on my heater set to 85F (slowly working up to what millet said. figure it'd be more shock to set it to 93)

thanks for bringing up root rot. Its definatly something I didn't think of. I just took the plant out so carefully. the sol wasn't overly packed... because when I too k it out, most of the soil fell from the root ball.

Hopefully it comes back

as long as all the stems are still green... I should be ok and the tree should come back, right?

I'm down to just a couple leaves on the tree, and the few that are there are VERY wilted... just waiting to fall off.

I just dont know what to do with it. Really worried. ALL my other citrus are putting out a ton of new growth, but this tree... just looks worse and worse and a lot more worse.

Keep soil moist NOT WET. Don't fertilize until you see some new growth. If the tree does not die, it could produce new leaves in 2 weeks to a month. Good luck. - Millet

I'm sure hoping. just looking like one sad sad tree

I think the tree is going to die now. This morning I noticed the tips of the branchesare starting to dry out and turn brown.

This really hurts, I haven't even had it for 2 weeks, it was a larger tree, I thought they wouldn't die as easily. HA I'm not going to fully give up until the last of the tree is brown. as long as theres a tad bit of green theres hope. I'm hoping with the warm weather coming, getting it out into the sun... will really help
