Is my Cycas revoluta pup rotten ?
I suspect my 3 inchs Cycas pup is half rotten as when I press it with my fingers it feels like a tomato. I feel it is somewhat tough inside and feels like a sponge from outside. This pup was like a tough onion a month ago when I chopped it from the base of the Cycas trunk and dried it for a week before planting it in the sea sand and perlite.
My greediness made me to keep the Cycas pup along with tiny pot inside microwave oven at 450W for 2 minutes and after 3 days a reddish/yellowish that looks like a wool formed over the grooves of the cycas pup and even during this time the pup was tough and slightly changed its colour to healthy red. After a week later I poured water to it in 4 inch pot. The next day when I touched it I realized I made a mistake pouring water. I replaced it in dry perlite. I checked the previous sea sand and found no rotten smell in sea sand as well as pup but the pup is somewhat spongy and hard. How can I rescue my pup ? I can't find pumice here.
