IS REAL SOIL GOING TO POT?

What’s in Your Mix?

That potting soil that you’ve bought for your seedlings and houseplants? It probably has no REAL soil at all in it. Real soil is just too hard to obtain in reliable and uniform quantities for commercial packaging. Soilless mixes, as commercial potting soils are (or should be) called, are a mix of some kind(s) of organic materials along with some aggregate, with possible additions of fertilizer, ground limestone, and a wetting agent.Cats with potted begonias

Organic materials in these mixes help sponge up water and cling to nutrients that might otherwise wash down and out of the pot. Peat moss is the organic material traditionally used in soilless mixes. Although it holds water well, it’s initially hard to wet, which is why wetting agents are sometimes added to soilless mixes. Read more

HAVE YOUR “CAKE” AND EAT IT, TOO

Take a Moment for Forethought

Luscious photos now splash pages of mail-order catalogs, the web, and plant tags at local nurseries. It’s hard to remain rational about planting this time of year, and more so the colder the last winter’s climate.

What I’m suggesting is to give plantings some forethought and, rather than looking for either ornamental or edible trees and shrubs, considering plants that fulfill both functions. That is, trees and shrubs that earn their keep year-‘round with leaves that remain lush and verdant all summer, then light up with fall color, and, of course, bear fruit, and perhaps unfold with eye-catching blossoms in spring.

Lots of trees and shrubs fill this bill, but here I’d like to restrict consideration to fruits that I would pop into my mouth right out in the garden; doctoring up as jam or in a pie is not obligatory.  Read more

SOIL PREP

Universal Plant Needs

Although garden plants hail from all corners of the world, they have surprisingly similar soil requirements — best attended to before planting. Simply put, most garden plants need soils that are well-supplied with air (yes, roots must breathe!), water, and nutrients. And one other important ingredient, organic matter (sometimes called humus), that witch’s brew of living and once-living organic materials in various states of decomposition that, in addition to contributing to the just-mentioned needs, also includes a friendly microbial community for optimum plant health.

Aeration must be the first consideration, since plants are unable to utilize nutrients, even in fertile soils, if roots lack access to air. There are two causes for waterlogged soils: either the water table is too high, bringing water up from below; or the soil has pores so small that they cling by capillary action to too much water that falls from above.

Deal with a high water table by either choosing another site for planting, by raising roots above the water table, or by lowering the water table. Growing plants in raised beds is the way to bring roots above a water table.
