If you have too many agave you need to castrate your pups.
I have moved away from Arizona but when I lived there my agave grew about 12" every 6 months. The mother plants had 1000s of babies. I sold babies on ebay 25, 50, 100 and 500 to a box. None of the babies have roots when harvested from the mother plant but they will in 3 weeks once I put them in the soil. Agave with no roots are hard to sell and 1" tall babies are hard to sell too. The mother plants grow a stalk and produce about 1000s babies they also send out roots and grow babies from the roots too. 1 plant will grow more babies than the average person knows what to do with. Desert plants are very hardy they can tolerate the hot desert sun, 115 degrees and almost no water but if you grow them in the shade, in good soil with water they grow faster than weeds. I sold almost $20,000. worth of agave babies one year on ebay every year. Not many people want to buy any type plant in the winter then spring you cant sell them fast enough then sales slow down in summer then speed up a little in the fall. Mothers day they make great gifts so get ready ahead of time for the biggest sale time of the year. Be careful not to leave baby plant in the soil too long if they get too large you cant get 50 in a $5 flat rate postage box. But don't worry you can get 50 larger plants in a large flat rate postage box for a higher sale price.
