    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.

Norfolk Island pine for Christmas

QUESTION: I live in a small apartment and don’t have room for a big Christmas tree, so I’m thinking of hanging ornaments and small lights on a Norfolk Island pine in a pot that is sold as a houseplant. How should I care for the plant when Christmas is over?

norfolk-island-pineIf you treat it carefully, a Norfolk Island pine is a fine small alternative to a big tree – you may even see them sold in some garden centers already bedecked with a few baubles. If you’re decorating your own, use lightweight ornaments – heavier ornaments could break the limbs – and use lights sparingly. A small string of LED bulbs should lend a festive glow. Remove everything shortly after Christmas is over.

As a houseplant, place the tree it in a cool room in a spot that gets bright, indirect light – a south- or west-facing window is good – and give it a quarter-turn once a week to encourage it to grow straight up.

The biggest threats to Norfolk Island pine are dry soil and dry air. Keep the soil consistently moist, but don’t let the pot sit in water. Increase humidity in its environment as much as possible. A daily misting could go a long way toward keeping the plant healthy. If the air remains too dry, the Norfolk Island pine responds by dropping its needles, and once they’re gone, they don’t grow back.

Houseplant specialists suggest using a balanced fertilizer once a month in summer. And be on the lookout for pests, because spider mites and mealybugs are drawn to this plant. A cautionary note about placing it outdoors when the weather warms up: it’s a very tender plant, and will be damaged if the temperature falls below 40 degrees.

With care, a Norfolk Island pine can last for many years. They are native to the South Pacific (Norfolk Island is a small speck of land between Australia and New Zealand), and in their home environment they grow very large. Indoors as a houseplant, the tree usually grows, over time, to about 6 feet.
