Hannah, Yellowing between the veins of older leaves generally indicates a lack of a transportable nutrient, such as Magnesium. What is the analysis of the Plantacote? It could be that it is too slow releasing for the needs of the A. x calidora. These plants are very vigorous and that means they need enough nutrients to sustain that growth. Otherwise, they will decline and die down or out. I give my host of Alocasia hybrids a soluble fert solution every week and I use a higher nitrogen mix as well, occasionally supplementing with extra iron and manganese. Even under these conditions, some of mine get a little pale from time to time, especially in the summertime growing months. Many, if not most, of these Alocasia like well draining soil mix as well, so if your soil is heavy and wet, that might be part of the problem. Healthy roots are a must for proper nutrient uptake. Hope this helps, LariAnn Garner Aroidia Research Here is a link that might be useful: Alocasia x calidora

@love_the_yard I was at the Lowes on Atlantic Blvd the other day and there were huge discount racks of all kinds of stuff. I got ground orchids 1 gallon for 3.00 -they are the orange flowered ones. No name on them except 'Ground Orchids' lol. I am pretty sure they are the tropical types and will have to overwinter in the gh in our zone grrr. I saw Belotti passiflora, white and pink mandevillea, and a bunch of annuals and other perennials on the discount racks. I think they were getting ready to put some 3 gal roses on there too because they were in the process of pulling them from the display and moving them to the discount area. I also saw some 3 gallon Sting Ray alocasias that were good size (I already had some of those). I might go back this weekend and see what's left on the discount racks though lol. We also have the 'wild' green alocasias on our property. Last summer one had a leaf as big as the hood of my car! I am thinking of making a huge fountain base or birdbath with a few leaves (concrete casting). They are soooo big! I don't like how they invade my flower beds but if there are few off by themselves somewhere they don't bother me. These things do reseed like crazy as well as make runners. The huge one by my car last year made about 50 seedlings. Hopefully most of them froze cuz I only see about 10 over there now. I keep my Mickey Mouse Taro in pots. It likes to go out the holes in the bottom of the pots and start new plants all over the place lol. It is definitely the cutest EE !! I saw some at the Ace Hardware in Mandarin that were obviously MM taro but they had them labeled as "Variegated Sting Ray" and a big "WOW!!" marked on the sign in front of them. Reminds me of the ebay seller ads. That Ace is normally a great place to find unusual things (in their gh) so I was kinda surprised at the mislabeling. I got a 3 gallon black Bat Plant last year. It was great and flowered nicely then one of the dumb roosters came and ate up the blooms grr. It is still doing good and overwintered in the gh where I only light the heater when it goes under 32F. So I think they are a little hardier than zone 10b/11. I have another baby black one and a baby white bat that overwintered in my somewhat cool gh as well. ~SJN

Cut them back and just put the bulbs in a paper sack or lcardboard box and move them that way. You can either replant right away as long as you aren't moving anywhere that it is freezing or wait and replant in spring if more convenient.

I have bought a couple of elephant ears last summer, and I have overwintered them indoors. The package says hardy to 15 degrees F. Tonight it's going to go down to 40*F and tomorrow night + the night after + the night after that, temps are supposed to reach 26*F + 27*F and then 27*F again before finally going to 34*F. They overwintered perfectly last night for elephant ears who have been indoors with themperatures at 70*F all winter long, with some wilting maybe even some defoliation, when temperatures went down to maybe 25 or less. I don't know just how far though. Before finally bringing them in for the winter, they dealt with temperatures down to 28*F and have recovered as if no frost ever happened. It was really awesome. Now, enough of my bragging, how far down can they go in a pot? Can they go down to 27*F for two nights in a row, with highs at 47 (day 1) 37 (day 2) and 35 (day 3)? Will they be fine or will they die? So, help is appreciated. Thanks.
