Gardening Tips and Techniques

Weeding

What is a weed? Essentially, it’s a plant that’s growing where you don’t want it to be. Weeds are opportunistic, springing up where there’s a void in the landscape, where the soil has been disturbed, or where birds and mammals have eliminated the seeds of the fruits they’ve eaten.

Raised Beds

Gardeners with heavy, clay, or even tainted soil might consider constructing a raised bed outlined with durable, untreated lumber. The boxed bed is then filled with a perfect, lightweight mix of topsoil, compost, and leaf mold. Other small-space gardeners who choose containers to grow their veggies and herbs can use this same mix for their pots. Any gardener who suspects the soil is contaminated should have a soil test taken prior to growing edible plants. This is best done when the soil temperature is above 50 degrees.

Repotting Orchids

Phalaenopsis

A Phalaenopsis, or moth orchid, is called the “gateway orchid” for beginning collectors: it requires very little care, and yields great rewards with blooms that last up to three months! Early success with a moth orchid leads growers to try other species and, finally, to orchid addiction. But how do you ensure early success?

Our first video details step-by-step instructions for repotting a Phalaeanopsis orchid.

Fall Garden Chores

Right about now, some gardeners are thinking about putting their gardens to bed and stowing the trowels and pruners.

Here are some things to do now before your garden winds down.

Winter Pruning

The Rantings & Ravings of a Pruning Freak

“When’s the best time to prune?”
“Anytime!”

It doesn’t matter what season you’re in because there’s always something that can be pruned. You just have to know the plant, its growth characteristics, its best time for pruning, and what your intentions are for that plant as it plays into the whole of your garden design.

“Well, I don’t have a design. I just plant stuff. If it lives, great. If not, then what?”

Here, Garden experts offer some suggestions for the small garden, whether an urban backyard or a rooftop, a border around a townhouse patio, or plant-filled pots on a balcony or deck.
