Yes, that is a canister vacuum. No, I am not suggesting that you vacuum your plants.
But I find that each week, as I clean up the house, I use either the wand on my vacuum, or just the hose, as shown here, to clean up around my plants.
Do I have that many messy plants? Oh yes!
This is just one example. This is my pittosporum tobira variegata. It’s a lovely plant and in mid-to-late spring for me it blooms with lovely small white flowers that have a wonderful fragrance.
But by this point in the season, it wants to be back outside. It’s a shrub. It really doesn’t want to be a houseplant, except that it’s not hardy in my region. So it gets finicky and starts dropping leaves. Sometimes a lot of leaves all over the place and on top of those other plants.
So once I clean the plants off (I repeat, I don’t vacuum plants–vacuums have too much suction for delicate leaves), I vacuum all the leaves up.
Then there’s my osmanthus fragrans–another plant that would be a shrub someplace else.
It’s a fairly good houseplant for me and it’s almost continually in bloom all winter with those tiny white flowers. They can perfume the whole room.
They can also make quite a mess of the windowsills, nearby plants, and anywhere else that they fall. But the vacuum keeps things neat and tidy with very little work.
Of course as you can see from the pittosporum photo, my plants are placed fairly close together so this technique is not for the faint of heart. If I am not careful, I can make more mess than I am trying to clean. But that hasn’t happened lately. I am becoming a pro at this technique.

Pittosporum tobira ‘Variegata’ made a new hedge for us. I am impressed that it and Osmanthus fragrans can live inside. The fragrance of Osmanthus fragrans is alluring out in the landscape, so it must be excellent, even if a bit excessive, within a home!
I keep thinking that I need to give that pittosporum a bigger container–and then I think, oh gosh, it will take over my house, so no. And yes, the fragrance of the osmanthus can be a bit much–but no more so than any of the other very fragrant plants like paperwhite narcissus or the jasmine officinale that I have about to bloom–they too can get fairly fragrant very fast. Even snake plant flowers are really pretty overwhelming!
Pittosporum tobira of any cultivar is easy to prune. I would prefer to grow it in a smaller container anyway, for portability. In the future, I would like to grow a few specimens of night blooming jasmine so that, besides adding more to the landscape, I could bring one inside while blooming. It is excessive, but I like it anyway. It reminds me of my first trips to Southern California.
