The Best Time To change Your Soil

The best time to change or refresh your soil depends on what you’re growing:

• Houseplants: Early spring, just before active growth begins. Replace the soil every 1–2 years, or sooner if it is compacted, drains poorly, smells sour, or has pests.

• Garden beds: Amend soil in autumn after harvest or early spring several weeks before planting. Autumn gives compost and organic matter time to break down.

• Raised beds: Top up with compost each spring; replace only part of the soil if it has settled or degraded. Complete replacement is rarely necessary.

• Lawns: Improve soil during the grass’s active growing season: early autumn for cool-season grasses and late spring for warm-season grasses.

Avoid replacing soil while plants are flowering, fruiting, heat-stressed, or dormant unless poor drainage, root rot, contamination, or infestation makes immediate action necessary. Often, adding compost and improving drainage is better than replacing all the soil.
