Osmanthus in autumn

Enjoy the autumn scent, keep roots evenly moist and check winter hardiness before planting out.

Plant bags explained

Choose the purpose first: rooting humidity, cold protection and fruit protection need different covers.

Acid-loving plants

Azaleas, rhododendrons, blueberries and several other favourites need acidic conditions. Test first, then choose the plant.

Growing basics

Dahlia winter storage

Lift carefully, dry the surfaces, and balance moisture in a cool place that stays above freezing.

Keep autumn mums

Check what you bought and how much growing time remains before choosing the garden or a protected pot.

Save zinnia seeds

Let selected healthy flowers mature, collect dry seedheads, and store the seeds only after they are thoroughly dry.

Fall peony division

Divide only when you have a reason, keep buds attached to sound roots, and prepare the new site first.

Plant garlic in fall

Choose your local planting window first, then give each clove a sunny, well-drained place for the winter.

Christmas cactus bud drop

When unopened buds drop, check recent changes and the potting mix before changing the feeding routine.

Amaryllis reblooming

A healthy bulb needs stored energy; a planned cool rest can help schedule flowering but does not guarantee a holiday bloom.

Indoor plant light

Find a useful spot, measure at leaf level, and try the steady-light DLI calculator.

Raised-bed soil calculator

Measure a rectangular raised bed, calculate the soil volume, and turn an optional purchase allowance into a practical bag count.

Watering & blossom-end rot

Check moisture, drainage and root disturbance when tomatoes or peppers develop blossom-end damage. Start with the growing conditions before adding amendments.

Compost browns and greens

Choose useful browns and greens, check moisture and airflow, and recognize when a home compost pile needs an adjustment or more curing time.

Watering calculator

Decide whether to water today or wait. Plant type, pot size, light, and season return a check interval in days, a next check date, and a finger-test reminder.

USDA zone finder

Look up a US ZIP code on the 2023 USDA Plant Hardiness Zone Map. See the half-zone and the average annual extreme low in °F, then open frost dates for the planting calendar.

Frost dates

Enter a US ZIP code for the median last and first 32°F freeze, freeze-free days, and an indoor-start tip. Dates come from the nearest listed NOAA station, not from the USDA zone alone.

Plant problem quiz

Tick what you see on a yellowing plant. The quiz returns the most likely cause and three next actions, starting with wet mix, dry mix, or low light.

Organic matter

Organic matter is the living and decomposing fraction of soil. See the 2% and 5–10% targets by weight, and decide whether to add compost or maintain what you have.

Prune roses

Choose a rose pruning window from the rose type and your USDA zone. Hybrid teas, shrubs, climbers, and a light fall tidy are different jobs.

Perennials after frost

Decide which perennials to cut after frost and which stems to leave until spring, including a short note on whether mums tolerate frost.

Winterize sprinklers

Shut off the water, drain the backflow preventer and pump, and blow out sprinkler lines before a hard freeze. Includes the safety limit: no unregulated compressor.

How to dry herbs

Harvest before flowering, air-dry, and store leaves that crumble.
