Hydrangeas for one and all

If I had my way every garden would have at least one hydrangea. What's not to love? They're easy, pest and disease resistant, have great foliage, and they add quiet, elegant charm to shady areas.

In case you're thinking "how boring" and "ugh" as images of giant blue mop heads come to mind, consider that there are lots of hydrangeas that don't fit the old stereotype. The delicate flowers of the lace cap hydrangeas, the upright, crisp white clusters of the pee gees that nod in the breeze, the sturdy oak leafs whose leaves fade to lovely reds and oranges in the fall. And don't forget climbing hydrangeas for that bare spot in the shade garden that you want to cover with handsome flat white lace cap flowers. Many actually do well in sun provided they get a little break from direct afternoon rays come summer...

Removing sod for new garden beds

One of the most daunting gardening tasks is turning an area of lawn into a new bed. Well, it doesn't have to be it you think in steps and approach your task methodically. Here are my suggestions:

Dig it out: This is how I've always done it. Get a sharp spade or a sharp shovel (dull tools=hell), cut out the shape of the bed (the fun part) and then dig it out. You may want to cut the sod into strips so that it comes up easier. Make sure the ground is nice and moist when you do this (if it's summer, soak it first) and make sure you get all the roots up. Early spring is a great time of year to do this. Have your teenage kid haul it away when your done or start a compost pile with it.

Till it: I would only recommend this if you're doing a large area. Also, don't bother with those little rinky dink tillers-they just aren't heavy enough to do the job-your shovel works better than they do. Again, water the area before your till it-esp if you have compact clay soil. Till until all the grass roots are destroyed. Rake as you go to remove clumps.

Smother the crap out of it: This seems popular with do-it-your-selfers, however most landscapers would not recommend this method-why? It takes too long. You're going to have to plan for next year's beds. Start in the summer by laying down cardboard or newspaper over the area of lawn you want out and then shovel some mulch, compost, grass clippings over the newpapers. Water it and keep it there for several months until the grass has died and the cardboard turns to mulch. I generally don't recommend this method because it's unsightly and not professional, but it does work if done right. Also, by smothering, you can kill not only grass but beneficial microbes in the soil. However, if you have a bad back, go for it.

Poison! Most lawn killers will do the trick quickly and effectively without turning your yard into a toxic waste dump. (Use boiling water or a vinegar/water solution if you want to stay away from harsher chemicals.) Follow the directions on the container, spray, wait a few days-dead lawn. Once the grass is dead and the herbicide has dried it's pretty much rendered harmless. You will need to still dig out the dead grass or till it, but it'll make your job easier once the grass is dead. Again, bad back people like this method. Hippies will roll their eyes in despair.

Whatever method you chose, do a thorough job. There's nothing worse than having grass coming up in four different areas of your new bed. Add lots of new compost to the newly dug area. Turn over the old soil of it's compacted with the new soil. Line your new bed with a plastic barrier if you wish, if not, that's fine. You're going to have to weed at some point anyway...there's no escaping that.

Caring for bulbs after they bloom

Back in my old landscaping days I had a few clients who demanded that their daffidols be tied up after they bloom. Fun stuff, rubber-banding 40 or more daffodils. Thankfully, this tradition seems to be fading out of style.

If you want to get a few good years out of your spring bulbs, let the foliage dry up naturally-don't cut if off until it has lost all green color and looks spent. The bulb seeks nutrients-via photosynthesis-through the leaves and they need to do this so that they can bloom for you again next year. If you don't like looking at a mess of foliage consider planting some annuals among them that will hide the fading leaves. Or consider just living with it. A yellow stem and a brown leaf here and there isn't going to kill anyone-hopefully.

You don't need to fertilize the bulbs after they bloom. They'll be preparing for dormancy and they do this just fine on their own. Don't forget where you plant your bulbs if you're going to be doing planting this year. Photograph them or mark them so that you remember. Or not, if you like mysteries...If you are really into bulbs and want to learn more about them and their care here's a link to the international bulb society: http://www.bulbsociety.org/About_Bulbs/index.html
