Import into Apple Calendar, Google Calendar or Outlook. Dates use the selected risk level and are planning estimates, not frost alerts.

Each window is a planning range. Check the forecast, soil and cultivar before planting; a later date is not automatically safer in hot or wet conditions.

Sow for overwintering

11 Sep - 2 Oct

Counting back 59 days from your first frost so the crop matures in time.

Sow direct

26 Feb - 8 Mar

Four weeks before your last frost.

Harvest

28 Mar - 12 Apr

Sow in succession. A single sowing gives you a single glut. Sow a short row every 10 days through the window above and you get a steady supply instead.

During wetter months, check that beds and containers drain after heavy rain. During drier months, plan how you will keep seeds and new transplants watered. Monthly averages can hide long dry spells and intense storms; they do not show soil moisture, humidity or this week's weather.

For rocket, also check drainage, sunlight and cultivar requirements. See the rainfall context above; humidity, irrigation and local pest pressure are not calculated.

Local growing check

Before choosing rocket for Batman

  • March is the wettest month in the rainfall grid, averaging about 78 mm. Check how your own bed drains and plan watering around actual soil moisture; monthly rain totals are not an irrigation schedule.

The temperature and rainfall tables on this page show the underlying climate estimates. How these suitability checks work · Record what happens in your garden.

Before you plant rocket

Use the calendar to plan ahead, then check the conditions in your own garden.

  • Measure the soil at sowing depth. Aim for at least 4.5°C (40.1°F); the calendar estimates soil warmth from air temperatures and cannot measure your bed.
  • Frost tolerance does not make saturated or frozen soil suitable for planting. Wait until the bed can be worked without smearing or compacting it.
  • Use the maturity range on your seed packet when choosing a variety. Cold, short days and transplant stress can make harvest later than the calendar estimate.

Decide between salad rocket and perennial wild rocket

Sow small quantities where you can keep the surface moist. Crowded seedlings can be taken as young leaves, while plants retained longer need room to develop.

Warm, dry weather encourages flowering and stronger leaves. Choose a cooler slot or some light shade in hot conditions rather than assuming that rapid germination means a long harvest.

Take young leaves regularly and compare flavour as the plants age. Plan the next small sowing before the old batch becomes coarse or flowers.

Growing in a container

Rocket is useful in accessible salad containers. A series of small sowings is usually easier to use than one pot allowed to become a dense, flowering clump.

What to record this season

How long did each small sowing remain tender before flowering? Add the cultivar, sowing date and conditions to your growing record so you can compare next season.

Why these dates

Sow small quantities where you can keep the surface moist. Crowded seedlings can be taken as young leaves, while plants retained longer need room to develop.

Cold tolerance varies with cultivar, plant age, acclimatisation and the duration of a freeze. A plant surviving frost does not mean its leaves, heads, flowers or developing crop will remain undamaged. Check the forecast and the variety's local advice.

This calendar uses frost-relative offsets as a starting point. Rocket are timed for direct sowing 4 weeks before it, and this page simply resolves those offsets against the frost date computed for Batman.

The median frost-free season here is 249 days, against 30 to 45 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.

Growing rocket in Batman

Can I grow rocket in Batman?

The calendar estimates a planting window, not a guarantee of success. March is the wettest month in the rainfall grid, averaging about 78 mm. Check how your own bed drains and plan watering around actual soil moisture; monthly rain totals are not an irrigation schedule.

When should I plant rocket in Batman?

Aim for 26 Feb - 8 Mar in an average year. If you would rather not gamble on the weather, wait until 13-23 Mar - by then frost has finished in nine years out of ten.

When might rocket be ready to harvest in Batman?

The estimated period is 28 Mar - 12 Apr, based on 30 to 45 days from the modeled planting date. Cultivar, planting material and growing conditions can change this interval; check the plant as well as the calendar.

How much frost will rocket tolerate?

Cold tolerance varies with cultivar, plant age, acclimatisation and the duration of a freeze. A plant surviving frost does not mean its leaves, heads, flowers or developing crop will remain undamaged. Check the forecast and the variety's local advice.
