What to plant in June in the UK

The planting guide above shows everything you can sow, plant out and harvest in June in your UK region — select your region to adjust the timing for your climate. June is one of the key months in the UK growing calendar, and knowing exactly what to sow now versus what to wait on makes a significant difference to your season's success. Use the beginner tags to prioritise easy wins if you're new to growing.

Why timing matters for UK planting

The UK's variable climate means that planting timing varies significantly by region. What you can sow outdoors in Cornwall in March may not be safe in Yorkshire until late April or even May. Frost risk, soil temperature and day length all affect germination and early growth. This guide accounts for those regional differences — giving you planting dates that reflect the actual conditions in your part of the country rather than a one-size-fits-all calendar.

Sowing indoors vs planting out

Many UK vegetables benefit from being started indoors on a warm windowsill or in a heated propagator before being moved outside once the risk of frost has passed. Tomatoes, peppers, courgettes, aubergines and sweetcorn all need this treatment in the UK. Hardy crops like peas, broad beans, carrots, beetroot and most brassicas can be sown direct outdoors as soon as the soil is workable. The guide clearly distinguishes between indoor sowing, outdoor sowing, and planting out so you know exactly what each task involves.

Planning your growing year

For a complete picture of your growing season, use this tool alongside the seed to harvest timeline to see how long each crop takes from sowing to harvest, the frost date checker to find your safe planting-out date, and the companion planting checker to make sure your neighbours get along. The monthly jobs checklist covers all the non-sowing tasks to do this month alongside your planting.
