It's time to repot. Keeping it in a 6-inch container for two years is way too long. Yes, those are pups coming out of the drain holes. You will need to cut them free, and root them. If it's a thin plastic pot, consider cutting down the sides to the drain holes to remove as much stem as you can and minimize damage. When you remove the plant from the container you will see that there are several very long and thick pale 'roots' winding around the pot, ending in a pups. These are rhizomes called stolons, and are the way Agaves propagate, emerging from the ground up to several feet from the mother plant. There are probably more than you can see emerging from the drain holes. Cut all of the stolons from the root ball. After callousing the cut end for several days, plant the rosettes in very quick draining and porous soil that is no more than 25% organic material, the balance being pumice, perlite, gravel, etc. in the 1/8 to 3/8 inch range. No sand. Use a 8-inch diameter (two gallon) or larger container. Because it is fall, the pups may be slow to root, so be very sparing with water until spring. Brad

I was going to start a thread on a similar situation. I have an agave that has rotted from the bottom up. Looks like the rot has stopped and all is dry now and it looks good (well, sort of OK) from the top. This is a medium sized agave and a bit of hard dead stuff I can't remove around the "soil line". I have 2 of these guys. I'm thinking just stick 'em in the potting mix and see what happens. Still I know this is different than starting from a leaf!!

Thank you very much for your reply Grenda! I am so happy to hear that my plant won't die from blooming. If it keeps growing though it might die from lack of space. Even though it's in the ground it's falling over onto the sidewalk. It is so incredibly heavy! Hopefully someone can suggest how to remove the pups so I can plant them elsewhere where they would have more space. It would also give me a chance to share this gorgeous plant with friends. ☺ Here it is in bloom already falling over

Are you planing to eventually plant them in the ground or keeping in a pot?Most Agave can handle a zone 8. Do you know what species your Agave is:)? About a month ago I got some Agave americana 'mediopicta alba' pups. Some had baby roots others none. I just planted them in 50% pumice, 30% perlite, and 20% cactus mix. I haven't watered them yet. I probably will give them a drink fairly soon. So for yours I would wait to water. These guys are tough. In a month you should have more roots. Then you can give a drink. Most if not all my Agaves are planted outside in ground. I am a zone 9b, but lots of Agave are cold hardy. Some are hardy down to zone 5. I'm not saying yours is though. My established Agaves get winter rain water. If you're keeping inside I wouldn't water more than once a month. Once spring comes around water every other week and if you're able plant in ground next spring. Is there a way you could post a pic of your little Agaves:)?
