Checking in on My Alocasia Corms and Tubers

2 Comments

About two weeks ago, I decided to check on my stored corms and tubers of my Alocasia plants. They are stored in my basement in cardboard boxes over the winter months from about October until April.

I stored them differently this fall because last year, the corms/tubers had some rot spots on them when I took them out in springtime to replant them. The new storing process I used in the fall of 2022 was documented in my prior post below on this blog site.

Mid-Winter

In late February, of this year, 2023, I decided to check in on the stored tubers and corms. And I’m happy to report that they are doing well. No rot spots. The change I made was to not use peat, use newspaper, and use mesh bags to insert the corms/tubers into individually and put in a cardboard box (instead of a plastic bin). I also cut air holes into the sides of the cardboard boxes.

Largest one – when I stored it in October (photo above).

As you can see from the photos above, the tuber of my largest Alocasia now has a papery covering. There are no rot spots and there is a bit of green, showing signs of life – it is doing well. This one, due to its size, would not fit into a mesh bag, so I just laid it on top of the newspaper. You will also notice when comparing the photo from October and the photo from February, the whole tuber shrunk a bit as it dried out, which is fine and normal.

The photo above is of smaller tubers and corms which I had dug up in the fall. These are still green, and I laid them out for about a week to dry out more in the fall, removed all the soil debris, and inserted those which would fit into mesh air hole like bags, and then placed them in a smaller box, with newspaper padding around, and loosely closing the box to allow air circulation, in addition to making some air slits in the side of the boxes.

I’m happy all looks fine so far. The place where I stored them is in my unheated basement that does not go below freezing but is cold during the winters. This year, we have had a mild winter thus far. Thus, the basement may be a little warmer than usual. I’ll look forward to when I can take these out in April or maybe May to get started in small pots to induce growth and then transition them yet again to my containers in late May to enjoy all summer.

Inserted into Mesh Bags, then placed in cardboard boxes in the fall season.

How it Grows

This photo shows a few years back. The plants are starting to grow and gives you an idea of the Alocasia’s form. This one grows upright and is a jumbo variety.

In the first couple years, the size of the plants did not grow as large as later as the tuber/corm grew larger and larger. As you can see in the next photo, the height of the leaves are taller.

Every summer season, I use different fillers plants. This particular jumbo Alocasia is so worth saving and regrowing. It seems to become more dramatic every year.

The stalks of the leaves are usually about 3 feet long along with the leaves growing 3 feet too.

The plant usually looks like this in the fall season, when I’m getting ready to cut it down and dig it out. I’ve documented the process many times.

Shown above are various posts as I overwintered the tubers and corms of my Alocasia plant (and plants as a result of more tubers over time). The process I used before, with peat and bins, had worked perfectly for other plants such as Canna Lily rhizomes and Red Banana Plant bases, but for this type of Alocasia plant, it seems better to store them more in a dry state, the way I showed above in the paper and in cardboard boxes, etc.

I hope this helps anyone out there who stores their tubers and corms over the winter. I’m in CT planting zone 6b. Our winters are becoming warmer due to global warming here in CT, and this year has been particularly mild. We got a snow fall this week but we haven’t plowed our driveway once yet – its been warm enough some days to work outside and other days, a bit chilly. We have not snow showed yet and it is March!

Upright Jumbo Alocasia

I purchased my first tubers of this type of plant in 2018 or 2019. These types of elephant ear plants love sun and do fine in partial shade as well. They are dug out in fall and replanted in my container gardens every spring (after spring frost), as soon as it is warm enough outdoors – usually around Memorial Day. I start them in small nursery pots inside to get started and it easy to keep them growing well each season. Because this plant is tropical, it can’t be left outdoors through our winters or freezing temperatures. In the fall, you can let frost hit the tops or cut them down before fall frost. It turns out storing them in paper has worked better to keep them dry and safe. This plant grows up to 72 to 92 inches tall. I plant the tubers about 4-5″ deep and enjoy their dark green glossy upright leaves all summer. They are a real showstopper if someone hasn’t seen them before. I think the mistake I made was I treated these the same as my Canna Lily rhizomes and red banana plant bases, but it is handled somewhat differently. Live and learn – that’s the life of plant enthusiasts!

Storing My Big Red Banana Plant

So It Can Return Again Next Spring

Storing Red Ban Plant_0010

Ensete ventricosum ‘Maurelii’ is a return visitor at my home.  I have fallen in love with this tropical red banana plant for so many reasons, but what has impressed me more than anything else, is how large it grew this year in my monster cement planter.

Although I’ve included this type of red banana plant in my container gardens before, I’ve never seen one grow this big so fast.  It reached a height of 8 feet tall with large leaves growing to 7 feet long and 1.5 feet wide.  It was at proportions I didn’t expect, but was very happy to witness.

As each new leaf grew and unrolled from its center throughout the summer, and even into early fall, I was in awe of its massive presence – and ability to stand so tall. By the end of October, the plant had a large fleshy trunk of a 1 foot diameter.

Planted on the eastern side of my home, the morning sun would rise to greet it every day.  By noon, dappled shade cast down upon it from the forest trees nearby.  And by late afternoon, its large showy tropical leaves with red coloring were wonderfully backlit by the afternoon’s setting sun.  I am not sure which part pleased me most, but each stage was worth taking pause in my day to enjoy.

There were so many times I took photos of my big red banana plant in the planter that it became a bit obsessive.  Even though it was difficult to get a good shot because of the glares and shadows – and its sheer size, I still clicked away taking as many as possible throughout the season.

I showed my big red banana plant to my family, visitors and unexpected guests when they were here.  Heck, I even made them pose in-front of it for more photos.

Later in the season, I finally broke down and did what I pondered doing.  I hired a professional photographer to take a few good shots.  The sounds of the camera clicking furiously made me feel as though I gave the ultimate red carpet attention to my plant.

Alas, the plant got hit by our first frost of fall on the evening of October 25th.  The next morning, I knew my guest would be leaving for a long winter’s rest. It was time to take it down and store the root base so it could return to visit again next spring.

STORAGE STEPS FOLLOWED

First, a quick and easy haircut.  All of its gorgeous long leaves, now darkened by the frost and wilted, were cut off with large pruning shears and tossed in a pile.

Second, using a bow saw large enough for the wide stump, I placed the blade about 12” from the base and began to zig-zag across.  “Timber,” I said, as the top portion fell to the ground with a loud thump. (To see a video of the cut, visit my HOW TO VIDEOS page.)

Next was the careful removal of the root base from the soil.  Using a shovel to go around the root mass and cut the roots in the soil, I carefully lifted the large base with a couple of firm tugs.

Hand-pruners were used to trim the long roots as a way to eliminate additional soft fleshy material that may have the potential to rot in the storage box.

With a soft brush and my gloved hands, I cleared away the final soil residue on the root base, making sure it was fairly clean and ready for its next step.  I also re-trimmed the cut end to be level and clean.

In a nice sunny spot, I turned the root base upside down and placed it on a milk crate to drain of excess water for one solid day.

Then was the box selection – a new home.  Inserting a light weight plastic bag into it, filling it with bedding material of peat moss, I then carefully laid the heavy root base in the center on its side.

Finally, covering it almost completely with more peat and loosely closing the bag. I shut the box and labeled the outside with the date, plant type, and a smiley face.

The last step was moving the box to a cool dark place in above freezing temperatures in my basement.  And then I said a little prayer. (You know, because it doesn’t hurt.)

THE STORAGE PRAYER

Oh Banana Plant – You were so sweet

So now I lay you down to sleep

Please come back or I will weep

Enjoy your restful place of keep

Until I reawaken you in twenty-six weeks

STORAGE PRACTICAL TIPS

Be careful to not dent, cut or nick the root base.  These can create wound places, serving as an invitation for mold to set in.

Take measurements so you will have a record of how large the plant grew and can compare notes in the following years.

Use clean, disinfected tools during the process to avoid transmitting any diseases to the plant.

Try to do the breakdown job before significant rainfall if possible.  It makes it easier to move from the soil.

Don’t wash the root base with water to remove soil. It only makes it wetter.  You want the base to be slightly moist but not soggy because this can rot in the storage box.

Reuse the peat moss every year – it last a long time, and is an excellent material to store root bases.  It holds moisture lightly and helps maintain a balance of air too.

After removing the root base, turn it upside down to allow water to drain out before storing it, but don’t let it get too dry.

Use a cardboard box with vents or spaces to allow some air circulation to set in.  You don’t want a box to seal tightly and leave moisture inside where it will rot the root base.

Select a plastic bag that is very light weight, like those used in grocery stores.  Close the bag lightly.  Do not tie it off – allow some breathing room.

THE STORAGE LOCATION

You want to find a location where it remains cool, but not below freezing.  Some references indicate a temperature range of 35° to 45° F.  I put mine in the basement by the door where it is coolest, but I also place the box on a bench so it is not in contact with the cold cement floor where condensation can possibly cause the box to get wet and then stay too damp.  If it gets frozen, your root base is going to die.  If it gets too warm, it will start to grow again.  You want to make sure it is just right.  For me, that spot in the basement seems to be the sweet spot.

FINAL NOTE

The storage prayer is optional, but I believe this helps.  And when you open the box next spring, you will hear the angels singing when you see your banana plant made it just fine to be your return visitor in your container gardens every season.
