I asked as similar question somewhere else a few weeks ago and someone suggested some additional shade. Definitely not sugar. Very dilute fertilizer. Don't abandon it. In spring it may suddenly come alive.

Hi, I would sugeest that you remove all dead debris and scraggly looking stems and start over. Take what is free of bugs and "healthy" looking and repot it into a smaller pot using fresh soil. Keep it in shade or filtered light and water when it appears to be dry on the surface of the soil. You can also root these in water if you wanted to try to save some of the stems. Good Luck, Kelly

How to Revive a Dying Lucky Bamboo Check Your Water Source and Stay Away from Chlorinated Water. Keep a Consistent Temperature. Maintain the cleanliness of the Bamboo bowl. Avoid over- and under-watering. Fertilize once or twice a year. Remove any dying or dead leaves and stems. Allow for Indirect Lighting. Insects must be removed from the plant.

Hi, Ema. Aloes are succulents and hold a lot of water in their leaves, which is why you cannot overwater them. The root system on one of my larger aloes rotted when 'someone' placed it in a soil that was hard and compacted. It was actually like cement when it dried. Because it was out in the yard I hadn't noticed until it was too late. Anyway, I removed all the mushy leaves and left it out in open air [no soil, no rocks] and out of direct sun for ten days. After it sealed / calloused over, I prepared a very high draining, loose substrate using a small 8-qt bag of purchased succulent soil to which I added about a cup of course grade construction / river sand [do not use beach sand ... think tiny rocks] and a cup of perlite. I dampened the substrate and placed the aloe in the pot ... Just placed it on the soil. That's it. It remained on my porch, where it would not be disturbed, not get rained on, no direct sunlight while it rooted. DO NOT water until after about four to six weeks, when you see signs of new growth. Succulents without roots have no way to uptake water ... They will only rot again. Once my aloe rooted and showed signs of new growth, I watered it and slowly began moving it closer and closer to full sun ... a little at a time so it doesn't burn. Burns can also cause rot. I'm happy to report that not only did it survive, it put out three pups within the first six months.
