This past month I have been houseplant obsessed. I’m not sure if it is because we have been under lockdown for so long, due to my love of anything green or my love of nature and gardens. Probably a combination of all three, much to the chagrin of my husband who keeps reminding me “The gardens are outside.” Hmmmmm, I can fix that, I do love a challenge…
Houseplants deserve TLC too, this time of year is as good as any to give them the attention they need. As we are still in lockdown here in the Ottawa area, with strict “stay home” orders, my green thumb is coming out this week.
Over time, the soil in houseplants gets depleted of nutrients and compacted, similar to the soil in your gardens and containers outdoors. As I cannot get out into my gardens yet, my front hallway is currently lined with bags of soil, pots, and plants. All of my houseplants will be getting fresh soil and bigger pots to spread their roots and strut their stuff with a chaser of diluted fertilizer to encourage root growth. If you are really ambitious, or you discover any rotting or dead roots, you can rinse your plants off before repotting them. A set tub works well for this job, although I prefer to do it in the summer, outside.
Typically I take stock of my houseplants in winter when my gardening business is snowed in, but this year I think I have taken this obsession to a whole new level. Recently, a large box of soil bags, plastic saucers that go under plants to protect floors, and pots has taken up space in my front hallway. The floor there is easier to clean up after spills, so this spot has become my potting station.
Research Your Options
The internet is a great resource for which houseplants to buy (or trade with like-minded friends for), what window to place them in, and how and when to repot and take cuttings. I love this site in particular; it provides lots of “how to” videos for all sorts of plantings.
I have also joined a Facebook group of other individuals in Ottawa that are as houseplant obsessed as I am.
My granddaughters and I have started seeds, with some progress. Currently, we have success with zinnias, strawberries, lemons, and lots of hibiscus. We will have to restart some in a warmer spot in the house; my basement kitchenette appears to be too chilly.
There are several other ways to propagate all plants, including houseplants. I am currently attempting a few methods to increase my own houseplant population.
Taking leaf cuttings and putting them in water (changing the water often) until roots develop is just one way but by far the simplest. This method works best on plants with hardy stems such as African violets.
Adding rooting hormone to leaf cuttings and inserting the stem into perlite (lightweight, volcanic glass pieces used to hold air in soil) or potting soil also works well. Sanseveria works well with this method; several sections can be cut from one leaf, just be sure to keep track as you cut them into sections so they are planted right side up. It does make a difference; if you plant the sections upside down (easy to do when removed from the plant), they will rot.
Air layering is another propagation method, but a bit more complicated. Make a slit on a stem (2/3 of the way through the stem) between two leaves, cover the wound with damp sphagnum moss, and wrap the area in plastic wrap to create a humid environment. When new roots form, cut the new plant off and pot it up.
Simple layering involves pinning runners or long stems into the soil while still attached to the parent plant to form new root systems. When the new roots and new shoots form, sever the connecting stem between the parent plant and the new roots/shoots and pot your new baby up. Pothos, ivy, and spider plants propagate well with this method.
Sometimes when repotting your plants the roots just naturally fall apart (divide) into separate clumps, creating another easy way to propagate and grow your collection or to share with others. Sanseveria (snake plants) and ferns lend well to this division method.
My perennial gardens outside are very familiar with the division method, with spring being the perfect time to do so.
Replenishing my Collection of Houseplants
For an introduction to a few new houseplants (one can never have too many) and some soil, I shopped online at the House of Plants, a small business here in Ottawa. Currently offering curbside pickup or local delivery with nationwide delivery resuming in the spring, House of Plants has not missed a beat during the pandemic. They offer a wide selection of houseplants, suitable for many different light conditions.
A while back I wrote about the role houseplants play in removing toxins from the air in our homes. With windows and doors closed tightly against the cold air and our furnaces running constantly, this air cleansing is more important than ever during the winter months.
Last summer gardening was a newfound hobby for many, during the winter months houseplants are now on trend. Whether you want to add to your existing houseplant collection or start one, contact House of Plants for all your needs and support their new business.
I am anxiously awaiting the arrival of spring but until then I will remain houseplant obsessed.
