Indoor Eden: Trouble in Paradise… Aphids & Scale Attack the Studio Oasis!
Pots in the Studio – Kalanchoe ‘Tessa’ (About to Bloom) Shares Space with Other Succulents (Mustard pot: Crassula ovata ‘Minimus’, Senecio macroglossus ‘Variegata’. Green pot: Kalanchoe mangini and Crassula ovata)
By now, it should be fairly obvious that I take as much pleasure in my garden during the winter months as I do during the warmer seasons. However on the grey and stormy days, when the temperature drops and the wind kicks up, there is much to be said for houseplants in January! I spend a great many hours in my painting studio at this time of year, and with its cathedral ceiling and bright, indirect light, it makes a perfect winter home for larger pots and taller plants. However this one room is hardly the limit of my indoor gardening. In fact, my entire house becomes something of aÂ winter oasis after the hard frost in mid-October, with plants distributed throughout the studio, kitchen, bedroom, bathroom, entry hall and secret garden room. In short, there are green, and multicolored things growing almost everywhere you look! And I love to admire the lush leaves and colorful blossoms against a snowy backdrop…
I Love the Contrast of Rich Green Houseplants Against a Wintery Back-Drop (That Red in the Snowy Background is Cornus alba ‘Siberica’ Beyond the Studio Door) Here, Kalanchoe ‘Tessa’ is About to Bloom, and Looks Particularly Luscious… Especially to Aphids!
Right now, my collection of Kalanchoe is about to blossom, and the various cultivars all look delightful -particularly to the aphids attacking them! It seems that sometime over the holidays —while I was too busy to notice the early signs— these nasty little freeloaders hatched and multiplied on one of my beautiful plants! Well, I caught them -and not a moment too soon. I pulled out my neem/soap mix (an OMRI approved insecticidal soap), and set to work spraying all of the foliage on this particular plant —and those sharing the space nearby— until it was thoroughly wet. Â Take that you sap suckers! Experienced gardeners usually know what to look for when it comes to aphids, but just in case you are unfamiliar with them, here’s a photo to help you identify the problem…
Of course, this unpleasant invasion lead me to investigate my other houseplants. And lo-and-behold, there on the fine foliage of my agave: scale! Ugh! Spritz, spritz, spritz; on again with the neem insecticide. I really dislike scale, and find it difficult to eradicate. If the neem/soap mix doesn’t do it, I will upgrade to horticultural oil. Although one of scale’s natural predators, the ladybug, is active in the warmer parts of my house, this overwintering insect seems to avoid the cool studio. I always carefully check for ladybug larvae (click here for photo) before spraying, because even organic insecticides can kill beneficials like ladybird beetles as well as —outdoors during the growing season— bees, other pollinators and helpful bugs. I will have to keep close watch on this scale situation and repeat application of neem or horticultural oil weekly. Scale can become a real problem indoors unless the gardener is vigilant.
Many of my houseplants move outdoors during the summer months, but some —like the giant Ficus pictured below— are permanent indoor residents. These larger plants require regular maintenance to look their best; including pruning, which is done from a ladder in some cases. It looks like I accidentally damaged a branch while turning this tree last month, so I’ll need to get up there and make a clean cut; removing the unsightly dead foliage…
After my rounds today —feeling the soil for moisture and checking all leaves and stems for pests and disease— I felt that most things were looking pretty healthy. I try to keep my houseplants on the dry-side during the winter months, but it’s important to strike a good balance between sahara and monsoon. The plants living in my studio —mostly succulents and many trees which are not particularly fond of humidity during the winter months— don’t seem to mind the dry, cool air. I keep most of the humid-air-loving tropicals —such as orchids, citrus and the mini-greenhouses: terrariums— upstairs in my bedroom, where I run a humidifier both for myself and my houseplants. I also segregate plants known and listed by the Humane Society as potential threats to my cat and dog (click here for article and links). The studio is closed up unless I am in there (where I can monitor munching), as is the Secret Garden Room.
Although It is the Most Commonly Grown Houseplant, Few Ficus benjamina Manage to Reach This Monstrous Height Before Getting the Old Heave-Ho. I Inherited This Specimen a Year Ago, After It Had Outgrown Its Former Home. The Weeping Fig Arrived by Trailer, and Is Now About 15′ High. The Studio is a Bit Cool for This Plant, But it Seems to Like the Bright, Indirect Light.
I May Not Have My Conservatory Yet, But I Can Still Fake It By Creating an Eden Indoors (Cycus revoluta in foreground)
Someday, I hope to have a tiny conservatory all my own. But until then, I can enjoy most tender plants inside my home by finding the right micro-climate to suit their optimal growing conditions and by carefully catering to their needs and desires. For help with houseplants of all kinds, I highly recommend Barbara Pleasant’s The Complete Houseplant Survival Manual. I am a fan of this author in general —I adore her book Garden Stone, which I’ve mentioned here several times— and I think this book is particularly useful for indoor gardening. Pleasant thoroughly covers the essentials of growing over 150 common houseplants and —unlike some of the other books on my shelves— it is both well photographed and well written; with carefully organized, richly detailed horticultural information. Dorte Nissen’s The Indoor Plant Bible is another great resource, and with its compact size, tough cover and ringed-binder format, I find that it stays out near the houseplants where it is frequently used for quick reference. Both books are set up encyclopedia/dictionary style; with all plants arranged alphabetically by latin name. Barbara Pleasant’s book is also broken down by plant group (succulents/cacti, flowering/foliage plants). If you are new to houseplants, these two titles would be my top-shelf recommendations for indoor garden reference.
It’s quite windy here today —and cold— so I won’t be spending much time outdoors. In meantime, I have my little Indoor Eden to content me and keep my color-loving eyes satisfied. My exotic houseplants bring a little bit of tropical warmth to my wintery world, and help me to more fully appreciate the stark and crystalline beauty of the landscape just outside the glass doors…
