Houseplants and I had a less than auspicious introduction. During the first winter I spent in Alaska, I was desperate for something green and cheerful. When I spotted a display of African violets at the grocery store, I happily slipped a pot into my shopping cart. But it didn’t cheer me up for long; its death was quick and upsetting. Despite that dreary beginning, I’ve kept trying. I’d always enjoyed success with outdoor gardening and I wasn’t going to let a little plant in a pot defeat me. Over the years, I’ve had quite a few more failures growing plants indoors — but some spectacular successes too.

Today, half a dozen plants thrive on my windowsill, and they give me no end of pleasure during the bleak months of winter. After years of experience, I’ve learned that the keys to success are three: don’t overwater; don’t let plants get root-bound in their pots; and find out ahead of time whether plants are fussy when it comes to growing indoors. How can you tell which plants are easy keepers? In my experience, any plant that easily roots from a cutting is equally easy to maintain as a houseplant.

Rooting a cutting is incredibly simple, considering the reward. All you need is a four to six inch piece snipped from fresh, new growth. Strip the leaves from the bottom two or three joints, leaving two to four leaves at the top. Coat the stem with a root promoter (Rootone is my preference). Then fill a pot with potting mix, poke a hole down the center (use the handle of a wooden spoon to make perfect holes), gently push the cutting far enough into the hole to cover the joints, and firmly press the mix down around it. Place the pot away from full sunlight and keep the potting mix evenly moist until your new plant starts to grow.

Good commercial potting mix can be hard to find, but I prefer it to garden soil because there’s no chance it will introduce a pest or disease. When I purchase potting soil, I look for a broken bag so I can see and feel what I’m getting. Good soil is light and loose and holds water well. If your garden has loamy soil (see “How to Improve Your Garden’s Soil“) you can use this loam for houseplants if you first sterilize it in the oven. Spread the soil in a thin layer in a shallow baking pan and place it in a 200°F oven for one-half hour — don’t expect it to smell like fresh baked bread.

How Much Is Enough?
