This past month I have been obsessed with houseplants. 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…
Indoor Potting Station
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 it 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 work 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 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.
I am anxiously awaiting the arrival of spring, but until then I will remain houseplant obsessed.
