Core planting options

The planting method matters: sowing seed and planting seedlings, tubers or nursery plants are different jobs. “Sow” means the underlying source does not specify direct sowing or trays.

Possible / shoulder planting options

These sit at the edge of the planting window and need more care with local conditions. They are kept separate from the core options.

In the garden in September

Use these jobs when the stated conditions apply in your garden.

Get spring beds ready

Prepare planting areas with finished compost and remove small weeds before spring growth gathers pace.

When this applies: Work only soil that is dry enough not to compact.

Year-round care

Check before watering

Check moisture around the roots and the rain forecast before watering. Water only where needed and follow local watering rules.

When this applies: Use the soil and plant needs to guide watering, rather than a fixed calendar interval.

How to do it

Prepare soil for planting

Before an intended planting, when soil is workable. Preparing a bed does not mean it is time to plant: check the plant’s window for your zone.

Check soil texture and pH

Before choosing soil amendments or a permanent planting. Recent lime, fertiliser or compost can distort pH results; follow the test instructions.

Decide whether your plant needs water

Before watering, after useful rain, and more often when plants are young or weather is hot or windy. This is a check, not a fixed watering schedule.

Sources and timing

Planting windows come from The Garden Hand’s existing planting calendar. Follow each plant link for its full growing guide. Garden jobs retain their existing zone, month and condition rules; year-round care is shown separately.
