Watering

The standard rule of thumb is about one inch of water per week, counting rainfall — over a 100 sq ft bed that’s roughly 62 gallons. In hot, dry, or windy weather plants use more; in cool or cloudy spells, less. Newly seeded beds and young transplants need steadier moisture until their roots take hold.

A simple rain gauge (or a tuna can under the sprinkler) tells you how much you’ve actually delivered, so you’re not guessing.

Water deeply enough to wet the soil 5–6 inches down, then let it dry somewhat before the next soaking. Deep watering pulls roots downward into a bigger, sturdier root system that rides out hot spells; frequent light sprinkles keep roots shallow and weak.

For most loamy or clay soils rich in organic matter, one thorough soaking a week does it. Fast-draining sandy soil holds less, so split it into two half-inch waterings a week.

Don’t water on a schedule — water when the soil says so. Dig down with a trowel: if it’s dry about two inches below the surface, it’s time. If there’s still moisture an inch or two down, wait. A crusty-dry surface over damp soil fools a lot of people into overwatering.

Both extremes cause trouble — too little stresses plants, too much rots roots and invites disease — so let the soil, not the calendar, be your guide.

Aim water low and slow at the base of plants so it soaks into the root zone instead of running off. Keep it off the leaves where you can: wet foliage, especially overnight, invites fungal diseases.

Early morning is the best time — leaves dry quickly as the day warms, and less water is lost to midday evaporation. A soaker hose or drip line is the easiest way to do all of this hands-off, and is well worth it for a beginner.

A 2–4 inch layer of mulch — straw, shredded leaves, grass clippings, or compost — is your watering ally. It slows evaporation, keeps roots cooler and more evenly moist, and smothers water-stealing weeds, so you water less often.

Keep mulch pulled back an inch or so from plant stems to avoid trapping moisture against them, and top it up as it breaks down through the season.
