This morning, I noticed a question pop up on one of my plant posts asking when I move my tropical plants indoors? And when do I start to store my Canna Lily rhizomes?
I have written a few times about my overwintering plants processes on this blog website.

Basically, tomorrow is the first day of September, and we still have plenty of time to enjoy our gorgeous plants outdoors on our patios, decks, and special places. I usually start to consider doing some of my outdoor work to move plants indoors around September 15th (for houseplants primarily).
If you have a busy schedule like mine in fall, or you wish to get a head start on your outdoor patios, you could potentially start moving in plants by mid-September. Some of these tips are outlined in the articles on my blog, as noted above. However, many plants may wait until early October. It depends on the type, the temps, and the condition of the plants. I basically have these types: succulents, agaves, canna lily, elephant ears, mandevilla, herbs, cacti, jades, houseplants, red banana plants, castor beans, and…, did I miss any?
I think, in my area of Connecticut (Zone 6), I usually begin around September 15th. I may start to harvest seeds which are ready (ripe) on some of my tropical plants, such as my Canna Lily plants. Look for dry papery pods on the plants and find the round hard seeds within them. Store them appropriately in cool dark places. I use old prescription pill bottles to store my harvested seeds.
I may start to inspect some of my outdoor houseplants (ZZ Plant, Jades, Mother In Law tongue plants, etc.) and spray them for insects (if needed) and/or wash the outside of the patio pots with dish soap water before I move them inside my house, one by one, over time. I usually like to move plants inside the home when the soil has had a chance to dry out too. I do not like moving them in when the soil is soaking wet – that only invites insects and other problems due to the lack of air circulation in the home compared to outdoors, and perhaps you have cool temps in your home due to air conditioning running. The soil may remain too wet indoors if the soil is soaked when you move them into a home.
Your herbs may be booming still, or perhaps they look ratty tatty and it is time to harvest the last of them. It is really dependent upon the conditions at your home and the exposure they get. My herbs are little on the sad side, but I’m gathering them up as much as I can when I cook each dinner every evening. They will stay a while longer on my deck. I could let them just go to blah, and throw the whole root ball out with plants later. No rush on the herbs right now. Again, all of my plants are in patio pots and large container gardens. They are not in the earth (gardens of the ground), so this process is plants in pots.
And my hot peppers are booming at this time (8/31/2021), so I take those in and freeze some or use them up in salsa’s, tomato sauces, etc. Yesterday, my husband accidentally chopped up one of my ripened to orange colored Jalapeños in his work salad. Good thing he can take hot spicy food! Our tomatoes are fading now and I probably will start cleaning up those big pots to get a head-start on my outdoor deck work.
I usually like to start moving my succulents into my greenhouse before any cold snaps and extremely wet conditions. This could start anywhere from 9/25 on. Last year, we actually had a firm hard frost on Halloween weekend, but we also got some quick cold frosty like temps over night before Halloween, on certain nights towards the end of October, before Halloween. I do not like my succulents to be soaking wet and cold before moving them in. Again, for the reasons noted above. Same with my agaves. The thing is with global warming and all our weather changes, it seems to be slightly different every year. I think frosts came earlier the year before.

Many large and showy tropical plants (like my Ensete, canna lily, and elephant ears) may be touched by frost on the foliage “if you are storing the underground tubers, rhizomes, corms” or whatever you want to call the underground storage organ from these plants.” But some of the work is just easier if done before frosts because the soil is not cold yet, and damp. I usually leave my showy tropical plants out in my big patio pots till early October. However, this year, I plan to be out of town the last week of September, which really makes me have to think ahead. Anyhow, they are fine to stay out if you want to do so. Or fine to start earlier towards end of September or early October to get a head start. If you don’t need a head start, just watch the weather for frosts in October. Also, if you are moving the whole plant intact, not cutting it down, leaving it in the pot – you must move it in before frost for any tropical plants like the canna lily, elephant ears, mandevillas, and banana plants, etc.
Another thing I might do early is start taking some cuttings of various succulent plants to propagate. It can take a long time to get those started, so I may take some healthy cuttings now. I inspect them for any insects first, make sure it is a healthy plant to propagate from, and follow my usual process for that at this time of year as well. I do not use damaged or unhealthy plants for any cuttings I may take. It just invites problems.
And lastly, I still have not cleaned all my spring and summer empty stock piled nursery pots! ACK! I started it a month or so ago and have some cleaned and piled nicely organized in my greenhouse – but the darn humidity really got to me this year. I just lost my motivation to tackle the rest of big pile of pots I need to clean and store for reuse every season. I still have to work on that. I try to do that now because it is more work for me in the spring when I start all over again.
So anyhow, one last big tip – always note on your wall calendar when your area of CT received light frosts and the hard frost of autumn so that the following season, you may recall when you did what. Watch the weather and think ahead so you are not caught rushing. And refer to this blog site for prior tips. I’ve posted for many years my processes and have shown videos too. You may find some of my prior videos of when I took down some of my big tropical plants on my Facebook page under Container Crazy CT.

A good post. Thank you 😊
You’re welcome. I did another post this am. It is raining here in CT and will do so overnight into Thursday – we will be getting some pounding rain! I moved some pots to protect them yesterday.
Good you moved some pots to protect them. You are welcome 🙏
