Tomatoes are usually started earlier and planted out in June rather than sown from seed now. In warmer temperate areas, or with greenhouse protection, quicker varieties such as Tomato Matina, Cherry Tomato Zuckertraube and Yellow Clementine may still be worth trying, but they are not the strongest June sowing choice for most temperate gardens.
Herbs to Sow in June
Herbs are useful, space-efficient and ideal for containers near the kitchen. In June, keep seed trays evenly moist and protect very young seedlings from drying winds or strong midday sun.
Basil loves warmth and is excellent for pots and summer cooking.
Parsley is useful for containers and repeated picking.
Dill grows quickly from seed and works well with vegetables and summer cooking.
Coriander is best succession-sown in small batches and kept evenly watered.
Thyme is compact, aromatic and good for pots.
Lemon Balm is forgiving, useful and well suited to container growing.

June Gardening Tips
In temperate Europe, June sowing is about using warm soil while keeping seedlings watered and protected from pests.
Warm June weather dries surface soil quickly, so water gently and consistently while seeds germinate.
Starting seed in trays gives better control before transplanting into beds or larger pots.
Sow small amounts of salads, herbs and quick vegetables every couple of weeks.
Watch for slugs, snails, birds and sudden hot spells while seedlings are small.
June is also a good month to start autumn and winter brassicas in cooler regions.
