Essentials of growing grass

The essentials for growing lawn grass are no different that for growing any other green plant: water, soil, mineral nutrients, and light. Basic botany, right? So when people are missing one (or more) of these essentials, no amount of the other two will compensate, and the grass won't grow. This lesson has been lost on person not too distant from TPP's neighborhood. As you can see here, some sparse newly sprouted grass is populating the shade under this tree, but in spite of adequate water (note the sprinklers and rain gauge) and presumably enough nutrients, the grass in this location is not going to grow into a thick, lush lawn; it will remain very sparse until some shade-loving weeds invade (Hello, creeping charlie!). Have you identified the species of tree yet! Well, you should have because it's one of the worst in this area for grass growing. It's a sugar maple, and they are handsome trees; some even have purple foliage. But sugar maples can make both sun leaves, bigger, thicker leaves on the outside of their crown, and shade leaves, somewhat smaller, thinner leaves adapted to the shady inner crown. As a result of this efficient light harvesting the mature crown of a sugar maple can intercept over 90% of the sunlight (figures of up to 96% have been cited) that falls upon the tree. Step under the crown and look up; what percent of the sky in view do you see? Bottom line: your grass won't grow because it is lacking an essential, light. You have no idea how often this turns up, and still sugar maples are touted as a good lawn tree. If you like your sugar maples, and you didn't prune the limbs up high enough to let in some light from the sides, you might as well give up and plant ferns or woodland wildflowers, and even some of them can't deal with shade this dense. Sorry, for the bad news; get over it. And get over the idea that lawns are just grass. If you'd asked 30 years ago, maybe you would have made another choice.

Early fall lawn grooming tips

Ah, the smell of freshly mowed creeping Charlie in the morning; nothing quite like it. Although the Phactors have extensive gardens, so big is our city estate that enough lawn remains to more than equal the amount of lawn on 3 or 4 or 5 standard-sized city lots which around here are 50 x 150. Now this would be an onerous task except that much of our lawn is in light to heavy shade so it doesn't require mowing very often. In these circumstances nothing beats creeping Charlie or blue violets, except maybe a shade-loving sedge. Lawn purists will wrinkle their noses and not a month goes by but when some chemical lawn care company leaves its toxic brochures tucked in our front door. Creeping Charlie and blue violets only grow so tall, and today's mowing was the first mowing of the shadiest area in 2 months. Apply chemical lawn killers to this area and nothing would be left but bare ground, and while this might be turned into forest understory, it really only looks good in the spring. This is because some of our other lawn "weeds" (trillium, wild ginger, blue bells, Solomon's seal) are not apparent because they are spring ephemerals. So tip number one is do not mow too often certainly no more than once a month. Tip number two is do not obsess about grass even if it is a minor component of lawn. Tip number three: buy a lawn mower capable to dealing with bits of bark, twigs as big as your fingers, and a smattering of leaves. This is part of having an ecological lawn. You know you're dealing with an obsessive when they speak of mowing the "grass" as if in some suburban universe a monoculture of grass is a desirable thing. As this blog is being written a neat, undulating sward of green spreads before the perennial gardens beyond. At this distance no one can identify the plants composing the green: neat, green, aesthetically pleasing, so what more is needed? Ah, just one thing, affirmation from an expert! And now you have it!

Tomatoes or grass?

As a youth, one of the characters that lived nearby was always getting us to help with various projects, and invariably we'd ask, "What will we be paid?" And his answer was always something like, "Two bucks and all the grass you can eat." So given the choice, tomatoes or grass, most people don't have to think very long. Thus it is nothing, if not sensible, to use your little bit of Lincolnland to grow tomatoes and other garden produce rather than having a monoculture of grass. Oh, but if you live in the village of Northbrook they may ask you rip out your garden and plant lawn for no other reason than your tomatoes are in front of your house rather than behind it, and some stupid ass has such a stunted aesthetic sense that they think a boring monoculture of grass looks better than a tomato garden. Clearly, life, liberty, and the pursuit of happiness is involved, and what brings more happiness than gardening and picking a vine ripe tomato? Song writer Guy Clark once observed that there are "only two things that money can't buy...and that's true love and home grown tomatoes." At what point does some bureaucratic git decide what is and is not prohibited? A garden need be neither weedy nor ill kept, which is what most lawn appearance ordinances prohibit. Attempts to define weeds as "aliens" will not work to eliminate tomatoes in favor of lawn grasses, since neither are natives, and there are probably more weeds in most lawns than in most kitchen gardens. Surely you can eliminate grass completely and plant annual and perennial ornamentals, and what is more ornamental than big, red fruits? But if the sight of a nice garden really offends, then my suggestion is that the garden be surrounded by a picket fence, lined with sunflowers, and the tomatoes and a machine gun nest camouflaged within, then when neighbors come calling for some tomatoes, or some petition passer comes prowling, both can get what they so richly deserve. Why next they'll be wanting gardeners to sit in the back of buses, step off sidewalks to make way for lawn mowers, and to eat plastic, store-bought tomatoes! Hmm, a couple of those tomatoes have a spot or two on them and are beginning to rot. We'll have to throw them away, tonight.
