    Tips & tasks – August

    Water lawns and garden beds early in the morning to allow foliage plenty of time to dry before nightfall.

    Container gardens will benefit from a light application of all-purpose fertilizer.

    If petunias have grown long and shaggy, cut them back and give them a dose of fertilizer. They should bloom again quickly.

    If squirrels and birds go after your ripe tomatoes, pick them while they are still green and allow them to turn red indoors. For best quality, don’t store fresh tomatoes in the refrigerator.

    Make sure spring-planted trees and shrubs get plenty of water during hot weather.

    Keep cutting the spent flowers of annuals so they will continue to bloom into the fall.

    To conserve soil moisture during hot weather, replenish mulch in annual and perennial beds as necessary.

    Begin planning a fall garden. Spinach, lettuces, radishes and other fall crops will mature when the weather turns cool.

    Begin clean-up of summer vegetable beds. Remove any decayed or dying foliage to prevent diseases from taking hold.

Water worries for houseplants

Question: I use tap water to water all my houseplants, but I’ve heard that’s not always a good idea. What difference does it make?

peace-lily-2Most people don’t think about the water they use to water houseplants —  just turn on the tap and fill the watering can. But what’s in your tap water may make a difference in how your plants grow.

Garden author Barbara Pleasant talks about water problems in her book, The Complete Houseplant Survival Manual. She says most plants prefer “soft” water, which contains low amounts of calcium and magnesium salts, over “hard” water, which contains high amounts of these elements. Water softeners remove the mineral salts through filtration or magnetization, but the water still contains high levels of salt, she says. This could lead to problems when it is used to water plants.

Houseplants’ soft water secrets

Question: Our home has a central water purification/softening system. Is this water good to use on houseplants? Or is it better to use water not connected to the system?

heart leaf philodendronMost people don’t think about the water they use to water houseplants —  just turn on the tap and fill the watering can. But what’s in your tap water can make a difference in how your plants grow.

Garden author Barbara Pleasant talks about water problems in her book, The Complete Houseplant Survival Manual. She says most plants prefer “soft” water, which contains low amounts of calcium and magnesium salts, instead of “hard” water, which contains high amounts of these elements. Water softeners remove the mineral salts through filtration or magnetization, but the water still contains high levels of salt, she says. This could lead to problems when it is used to water plants.

Pleasant suggests using rainwater or bottled distilled water, which are naturally soft, on your indoor plants.

The mineral salts in tap water are only one thing to consider. Plants may also be sensitive to too much chlorine, which is added to tap water to prevent bacteria, and some plants, including palms and dracaenas, are sensitive to fluoride.

To solve the problem of too much chlorine, allow the water to sit out overnight, so that chlorine and other chemicals escape into the air. If you suspect fluoride may be causing a problem (browing leaf tips on plants may be a clue), it may help to add a pinch of lime on the surface of the pot every few months, Pleasant advises. “This helps raise the pH of the soil, which makes the fluoride more soluble in water.

One other watering tip: whatever the source of the water, make sure it’s at room temperature when you water your plants. Drenching a houseplant in icy water chills the roots, which can cause them to rot, Pleasant says.
