Q: Now that we’ve had some winter rains I want to start planting shrubs and trees. I have found that online companies have better selection and availability on some plants. Can you recommend some Internet nurseries that are reputable?

A: I regularly buy plants online when I can’t find them at local nurseries. Although initially a bit smaller than the ones at a garden center, mine have quickly grown to the size I anticipated. I think the best source of gardener-rated online plant catalogs is the Garden Watchdog, www.gardenwatchdog.com .
