Why basil tries to bloom when you want leaves

Why basil tries to bloom when you want leaves

A basil plant in July can seem to break a small kitchen promise. For weeks it gives you soft green leaves, each one smelling like summer before it even reaches the cutting board. Then, almost overnight, the top of the plant changes shape. The leaves become smaller. The stem lengthens. A pale green spire of buds appears where a handful…

The white dust on summer leaves

The white dust on summer leaves

Powdery mildew often arrives looking almost harmless. A squash leaf that was green yesterday appears dusted with flour. A phlox stem has a pale bloom on its upper leaves. The cucumber patch still looks productive, the zinnias are still bright, and yet the garden has acquired a strange white weather of its own. The first instinct is usually to blame…

Why strawberries wear their seeds on the outside

A June strawberry looks wonderfully straightforward until you look at it too closely. It is red. It is sweet. It fits between two fingers and leaves a little shine on the thumb.

Why magnolias gamble with spring

Why magnolias gamble with spring

An April magnolia can look almost unreasonable. The grass is still thin, the perennials are barely showing, and the rest of the tree has not bothered with leaves. Then the branches open bowls of pink, cream, purple, or white into the cold air, as if the garden has skipped several pages and landed directly in bloom. That early display is…

The small pink rooms under pea plants

The small pink rooms under pea plants

A pea seedling looks simple when it first breaks the soil. Two pale halves of a seed have done their work below, a green shoot has hooked upward, and the first tendrils begin searching for something to hold. From above, it is all freshness and appetite. From below, if you lift the plant carefully a few weeks later, there may…
