    Tips & tasks – September

    Cut the dead tops of coneflowers, but leave enough for goldfinches to enjoy the seeds.

    Plant cool-weather vegetables for a fall crop: spinach, mustard and turnip greens, radishes, leaf lettuce.

    Start a new lawn of cool-season grass, such as fescue, or refurbish or repair establish lawns.

    Don’t let the soil of newly planted grass dry out. New grass needs about an inch of water per week.

    It’s still warm, so continue to water and weed garden beds as needed.

    Remove dead foliage, spent flowers and other garden debris; replenish mulch as needed.

    Continue to harvest produce, which may be getting a boost now from slightly cooler weather. Keep watering sage, rosemary and other perennial herbs so they’ll be in good shape to get through winter.

    Prepare to bring houseplants back indoors: remove dead leaves, scrub soil from the sides of the pots, treat for insects. Bring tropical plants in before nighttime temperatures dip to 55 degrees.

What’s blooming indoors? Meyer lemon

I have a Meyer lemon tree that I keep indoors. It’s often full of blooms and the flowers smell wonderful. I’m always looking for lemons to start growing, but the flowers dry up and fall off and I never get any fruit.

You’ve heard of the birds and the bees, right? Outdoors, flying insects (bees and other pollinators) go from flower to flower, dipping into the pollen on the stamens – the cluster of thin filaments — and spreading it to the stigma at the center of the flower.

Indoors, if you want fruit, you’ll have to take care of that little detail yourself. Lemon trees are self-pollinating, meaning that the flowers shed pollen directly onto the stigma, but they still may rely on wind or insects — or human intervention, if necessary — to shake things up.

Here’s how you can help: As the flowers open, use a cotton swab or a small artist’s paintbrush to collect pollen from the anthers (the tips of the stamens), then rub the stigma with the swab to transfer the pollen. It’s a slow process, but the tree should begin to produce lemons (which grow fairly slowly, by the way).

Meyer lemons growing indoors where winters are cold need a lot of sunlight, and they also benefit from time spent outside when the weather warms up. Place a lemon tree in a protected spot outdoors, moving it gradually into full sun, when nighttime temperatures stay above about 50 degrees. Outdoors, the bees will do the job of pollinating the flowers, of course.

In general, Meyer lemon trees thrive in good potting mix in a container that drains well. Make sure the soil doesn’t dry out completely, but don’t overwater it, either. Fertilize regularly with an organic fertilizer designed for citrus, following directions on the label. (I’ve used Espoma’s Organic Citrus-tone citrus and avocado food, with good results).
