The mayapple hides its flower under an umbrella

The mayapple hides its flower under an umbrella

By early May, a mayapple patch can look less like a group of wildflowers and more like a small green weather event. Smooth stems rise from the leaf litter, each one holding a pale, lobed leaf like an umbrella that has just opened after rain. The effect is so architectural that it is easy to miss the plant’s real trick:…

The spring viscosity chart your garden refuses to respect

The spring viscosity chart your garden refuses to respect

Welcome. Many of you have written to us this week, bewildered that our standard compost round-up has been replaced by a rigorous analysis of synthetic crankcase lubricants. Let us be clear: this is an oil publication now. It has always been an oil publication in spirit. We were simply waiting for the horticultural community to admit that dirt is just…

Why cut tulips keep moving in the vase

Why cut tulips keep moving in the vase

A vase of tulips rarely stays where you put it. Arrange it in the evening and the stems may look composed: upright enough, tidy enough, each flower holding its own small cup of color. By the next morning, one bloom has leaned toward the window, another has climbed above the rest, and a third has made a soft curve over…

Why maple sap runs before the leaves

Why maple sap runs before the leaves

On a cold February morning, a maple with a bucket on it can sound more awake than the rest of the garden. The beds are still flat. The lawn is patched with old snow. The buds on the branches look tight and undecided. Then, from a small metal spout in the bark, a clear drop gathers, falls, and ticks against…

Why rhododendron leaves curl in the cold

Why rhododendron leaves curl in the cold

On a January morning, a rhododendron can look as if it has lost its nerve. Yesterday the leaves were broad, glossy, and almost tropical in their confidence. Today they hang like narrow green cigars, each one drooping from the twig and curled along its length as if the whole shrub has tightened itself against the cold. It is an alarming…

The brown dots under fern leaves are not pests

The brown dots under fern leaves are not pests

On a January windowsill, a fern can look like the most innocent plant in the house. Green fronds, soft shadows, a pot that asks mostly for humidity and restraint. Then you turn one frond over and find rows of brown dots underneath. They can look alarming if you were not expecting them. The dots may be round, rusty, tan, black,…

Why fruit trees count winter before they bloom

Why fruit trees count winter before they bloom

On a cold January morning, a fruit tree can look almost empty. The leaves are gone, the grass is flattened, and the branch tips seem to be holding nothing more interesting than brown dots. It is easy to walk past an apple, peach, plum, cherry, pear, or blueberry and think the garden has become a diagram of waiting. But those…

The green thief in the winter tree

The green thief in the winter tree

By the last morning of the year, a deciduous tree has usually stopped pretending. The leaves are gone. The soft green noise of summer has fallen away. Every fork, scar, old pruning cut, and awkward branch angle is suddenly visible against the winter sky. That is when the green clump looks most suspicious. High in an apple, poplar, maple, hawthorn,…

The winter sunburn on young tree trunks

The winter sunburn on young tree trunks

On a bright December afternoon, a young tree trunk can seem to be enjoying the only warm thing in the garden. The beds are flat, the hose is asleep, and the mulch is edged with frost, but the low sun lands on one side of the bark with surprising force. If there is snow on the ground, the light comes…

The garden below the waterline

The garden below the waterline

Most winter garden work happens above ground: cutting back blackened stems, emptying pots, gathering leaves, pretending the hose should have been put away last week. But one of the strangest small gardens you can keep is almost entirely hidden from that view. It sits in a tub, a half barrel, or a small pond, and its leaves do their work…
