Time to repot agave bulbils — i.e., Moby spawn


Two months ago Moby, my big whale’s tongue agave (Agave ovatifolia), bloomed and sent up a tree-sized flower stalk, on which hundreds of bulbils (baby agave clones) eventually formed. You can read all about that here and here.

I kept them misted through the last weeks of summer, but lately it’s turned cool and rainy — something agaves don’t like very much. Now that they’ve had time to root, I’ve given many of them away to friends near and far. One of those, Jenny at Rock Rose, told me she unpotted hers and found long roots circling the 4-inch pot, so I knew it was time to replant those I intend to keep. I selected 6 nice ones and gently shook the damp soil from their fragile roots. I bought 6 Italian terracotta pots from Shoal Creek Nursery (Italian terracotta doesn’t crack when it freezes like Mexican terracotta)…


…bagged cactus potting soil, and perlite to improve drainage and avoid root rot. (Pumice would be preferable to perlite, which floats, but I didn’t have any on hand. Next time I’ll order in advance.) The sales guy at Shoal Creek advised washing the perlite in a colander to flush out excess fluoride and to keep it from blowing around, which was easy thanks to this handy plastic colander and scoop from Tubtrugs, which I won as a door prize at this summer’s Garden Bloggers Fling.

Next I mixed one part cactus mix with one part perlite and filled the terracotta pots, first placing a small square of fiberglass mesh screening material over the drainage hole in the bottom. This is optional but helps keep out ants and hold the soil in place while still allowing water to drain freely.


With each pot filled partway, I placed a baby agave in the pot so the roots were spread out and down and then added more soil, gently pressing it around the plant.


Here they are, all potted up.


Gravel or rock mulch keeps the perlite from floating to the top of the soil when you water, plus it insulates the soil and gives a finished look to container plants. I bought vase-filler river stones and gravel at Target and spread a layer of black river stones atop each pot.


That’s better! For now they’re basking in the gentle autumn sun on the deck rail. Grow, Moby spawn, grow!


I still have some Moby babies left in my mobile potting station (a Gorilla Cart that I’ve covered with metal screening to keep out squirrels). Most of these are going to friends who’ve called dibs on a pup or two. But I hope to have a few leftover next spring to give away to a lucky reader or two! But wait — what’s that on the left?


Babies from a ‘Bloodspot’ mangave that bloomed months ago and finally produced bulbils of its own! Yes, I’m officially addicted to potting up bulbils. Grow, mangaves, grow!

Potting up agave bulbils


My whale’s tongue agave, Moby, came down last week. This week I’ve been sorting and planting bulbils (baby agave clones) from the bloom stalk. I’ve never had an agave bloom before, much less harvested its bulbils, so I looked online for advice and found Len Geiger’s helpful post at Married to Plants and followed his instructions.


First I used hand pruners to remove clusters of bulbils from the bloom stalk. Mine looked different from Len’s in that short flower stalks were coming up from the bulbil mass. I don’t know why. I picked through each cluster, pulling away and discarding the flowers and trying to find easily removable bulbils, as Len advised.


Many of the bulbils came loose in clusters, which makes it hard to separate tightly connected bulbils without breaking them. I tried gently pulling them apart and discarded those that broke off too high, keeping those that had little nubs of roots.


Mid-sort, the green tub on the right contains unsorted bulbil clusters. The red tub contains the best of the harvested bulbils.


The final harvest. Most are very small, but a few bigger ones stand out. I’ll keep a half-dozen of these as insurance, in hopes that I get 2 or 3 well-rooted plants to carry on Moby’s legacy.


Next I set up my potting supplies: bagged cactus potting soil, bunches of old 4-inch nursery pots, rooting hormone and a dish to put it in, a cup of water, and a trowel. My potting station? A brand-new Gorilla Cart that I won in a raffle at the Minneapolis Garden Bloggers Fling! It made a perfect set-up, as I can move it around for more or less sun very easily (and in and out of the garage when it freezes in a few months), and the mesh sides will help keep squirrels from digging in the pots while the agaves root.


Here’s what an ideal bulbil looks like: a clean break at the bottom with a little nub of root, already hardened off in a shady, dry place for a couple of days.


Per Len’s instructions, I dipped the bottom of each bulbil in a cup of water before dipping it in rooting hormone (the water helps it stick). He said rooting hormone may be unnecessary, but he uses it, and I thought it couldn’t hurt, especially since many of the bulbils are very small, with less root than this one.


Then I made a small hole in a soil-filled 4-inch pot and stuck the bulbil in, gently pressing the soil around it.


One Gorilla Cart filled! Len didn’t mention how often he waters his baby agaves while they root, but I’ve been misting mine once a day because it’s 100 degrees out. I’m keeping them in bright shade under a live oak, where they’re getting a bit pelted with acorns, but the Death Star is too much for them right now.


Here’s the final result. I ended up planting about 120 bulbils. (Sharp-eyed readers will notice a few squid agave pups in there.) Many are teeny tiny, and who knows if all of them will root. I’ll know in a couple of months. Meantime, I’ve wrapped rolled wire over the pots to discourage squirrels, who at this time of year are burying acorns like treasure-hoarding pirates. I can just picture them yanking out agaves and filling the pots with acorns.

You may be wondering what I will do if all 120 root. Well, I’m giving many of them away to agave-loving blogger friends in Austin and beyond, although I’ll probably wait to mail them until next spring, when they’ll be established and I won’t have to worry about them freezing in transit as they go through Denver or wherever. If I have leftover Moby Jr.’s at that time, I’ll have a giveaway of them here at Digging, so stay tuned!

Goodbye, Moby: Removing a dying agave


It was time. Moby, my 11-year-old whale’s tongue agave (Agave ovatifolia), valiantly hung on for months after flowering, eventually making bulbils at the top of the bloom stalk. I’d been anticipating the leaf collapse that has occurred with every other agave I’ve ever seen in bloom, and yet Moby continued to remain upright. Still, after that spree of reproductive energy, he was now looking distinctly unhealthy, with yellowing, rotting leaves on the sunny side, although on the shadier side he still looked fine.


I took these two pictures on Sunday as a final farewell, as I’d scheduled a landscaping crew to come remove him on Monday morning. And then one of our cars wouldn’t start (bad alternator), and we had to have it towed to the repair shop, and Moby got a last-minute stay of execution — or should I say euthanasia?


Yesterday, though, the ax finally fell.


These two hard-working guys came over after lunch and worked on the removal for several hours in 93-degree heat. They were surprised when I said I wanted to keep the stalk intact, which made cutting it down a bit trickier. First they cut out Moby’s upper leaves. Then they began sawing through the stalk.


That stalk is huge — and heavy! Worried it would fall onto our string lights or the bottle tree, my husband and I rustled up a rope so they could pull high on the stalk and sort of control the fall. One last cut with the saw, and the stalk fell with a tremendous thud onto the gravel path along the fence, crushing nothing except a few of Moby’s precious bulbils.


These guys were such good sports, posing for the crazy lady who kept taking pictures of the decimated agave and fussing over the bulbils. They placed the severed stalk in the lower garden, and I’m planning to harvest the bulbils tomorrow and see how many viable ones I’ve got.


Not quite as many as I’d hoped (much of what you see here is flower stems on bulbils that are blooming — how weird is that?), but enough to keep some and share with friends.


A cross-section of the massive bloom stalk. The base has a diameter of 5 or 6 inches.


The guys went back to work on the agave, using a machete to chop off the fibrous leaves.


They wore gloves, which was smart, but they forgot or didn’t know to wear long sleeves to keep the agave sap off their arms. Soon their forearms were red and blistering from the toxic sap, and I ran inside to get soap and wet towels so they could scrub it off. Thank goodness they didn’t get it on their faces. That has happened to me.


This is why Agave ovatifolia is called whale’s tongue. Just look at the size of those wide, cupped leaves.


At last Moby was “pineappled”…


…and they started digging and sawing underneath to sever Moby’s tenacious roots.


Finally free


At this point several big cockroaches scurried into the open, like rats off a sinking sink, sensing, I guess, that their home under those spiny leaves was no longer safe. Gross.


After several tries, straining with effort, the guys were finally able to roll Moby out of the garden bed and up onto the patio. I bet that agave heart weighed 350 pounds, maybe even 400.


Somehow they got it up into the wheelbarrow and rolled it out to their trailer.


Goodbye, Moby! You will be missed. But hello Moby Jrs! Stay tuned to find out how many clones Moby made.
