    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.

Coffee grounds as mulch? Don’t do it!

I get coffee grounds from my local coffee shop. Can I use them directly on the soil as mulch (without mixing anything into it except to rake it into the soil)? The grounds are wet when I get them from the coffee shop. Should I let them dry out a little before putting it on the soil?

coffee groundsIn just about every listing of “ingredients” for a successful compost pile, you’ll find coffee grounds among the nitrogen-rich kitchen waste “green” ingredients that make up the mix. But it’s a mistake to use coffee grounds alone. They are very acidic, and over time will change the pH of the soil – the measure of its acidity or alkalinity – to the point that plants that prefer alkaline soil will suffer. Even around plants that prefer acid soil – blueberries, azaleas, rhododendrons – you will likely find that an overabundance of coffee grounds make the soil too acid and will damage the plants.

This information is from gardening expert Mike McGrath, whose gives out garden advice in a radio program, in print and other formats, including the website of the eco-friendly retailer Gardens Alive.

Coffee ground are so rich in nitrogen that you risk creating a “mold bloom” where you spread them “raw.” In addition, the life in grounds alone has been perked away. Create good compost by adding the grounds to yard waste – McGrath suggests four parts shredded leaves to one part grounds by weight.

Other components of good compost can include “green” (nitrogen-rich) items such as fruits, vegetable and fruit peeling and cores, tea bags, egg shells and other kitchen waste, grass clippings, weeds without seeds; and “brown” (carbon-rich) items such as dry leaves, straw and hay, wood chips, newspaper, paper towel tubes, dryer lint, pet hair. Don’t add meat, fish, grease, bones or fat to compost.
