    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.

For houseplants, go easy on the water

Question: I’m told I’ve been over-watering our houseplants, yet we have sprigs of plants rooting in jars in nothing but water. How can a plant be over-watered when it can also be rooted and flourish in water? And how do you know when you’re watering too much?

Houseplant experts agree that over-watering can have a detrimental effect on houseplants. Soil that stays too wet causes the plant’s roots to rot, and invites fungi that thrive in moist conditions. That’s why it’s important to grow houseplants in pots with adequate drainage, and to allow the soil of most plants to dry between waterings.Different houseplants also have different water requirements, and many need less water in winter when they are growing more slowly. Before you add water, poke a finger into the soil, and only water the plant if it feels dry. Or push a wooden chopstick into the soil, and if it’s not damp when you pull it out, water the plant. It is better for a plant to have too little water than too much, but you also want to make sure it doesn’t wilt.

As for plants rooting in water: many fleshy plants will quickly develop roots in plain water and can later be planted in soil. Ideally, as the roots develop, the water is kept clean by being changed frequently. But if they are kept in water long enough, even those plants that seem to thrive for awhile will eventually lose vigor and may rot, too.
