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 August

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

Check where rain goes

After rain, look for surface pooling and heavy leaf layers that stop water reaching the soil. Move excess leaves into compost.

When this applies: For winter-rainfall gardens; pooling needs diagnosis, not automatic extra watering.

Catch weeds before seed

Remove weeds before they mature and set seed, taking their roots where practical.

When this applies: When winter rain brings weed growth.

Repair garden essentials

Check garden paths and irrigation for repairs you have been putting off.

When this applies: A seasonal reminder, not a task that must be repeated monthly.

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

Remove young weeds by hand

As unwanted seedlings appear, ideally before flowering and seed set, while soil is moist enough to release roots but not waterlogged.

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.
