☀️ What to Plant
in June
June is a month full of work and reward. The garden is in full bloom, vegetables are growing fast and the first crops are ready to harvest. Water regularly, hoe weeds and keep an eye on pests. Summer pruning of fruit trees should not be forgotten.
💧 Water and care for
June demands regular watering. Water in the morning or evening — never at midday in full sun. Feed fruiting and flowering plants weekly.
Water, tie in and remove side shoots weekly. Consistent watering prevents blossom end rot and fruit cracking.
Water and feed weekly with a high-potash fertiliser. Pepper plants like warmth — in cold spells, protect with a cloche.
Water generously and feed every 2 weeks. Cucumbers are mostly water — drought causes bitter fruit.
Water generously at the base. Give each plant plenty of space — they spread 1–2 m. Feed fortnightly.
Stop watering both in June to allow bulbs to ripen. Garlic is ready when leaves begin to yellow and fall over.
Pinch out growing tips beyond the last bunch. Remove leaves around bunches for better air circulation and sun exposure.
Water regularly and pinch out flower tips to keep leaves coming. Basil bolts quickly in heat — keep it bushy.
Water daily and feed weekly. Deadhead regularly to keep flowers coming. One of the best balcony plants for June.
✂️ Pruning & trimming
Summer pruning keeps trees and hedges in shape and reduces disease risk. June is the only correct time for walnut.
June is the ONLY correct month for pruning walnut in Czech Republic. Walnut bleeds heavily in winter/spring. Summer pruning after leaves fully open avoids this.
Cut back new extension growth to 4–5 leaves. This is the summer pruning that shapes the tree and improves fruit quality.
Prune IMMEDIATELY after flowering — removing spent flower heads and shaping. Lilac sets next year's flower buds in summer, so late pruning removes them.
🧺 Harvest in June
June brings the year's first big harvests. Strawberries and cherries are the highlights.
The main strawberry harvest! Pick every day in peak season. Remove runners unless you want new plants.
Harvest ripe cherries as soon as they colour — birds will strip the tree in hours. Net the tree or pick promptly.
Harvest red currants in full bunches. They keep well for a week in the fridge. Great for jams, juices and desserts.
Harvest young pods regularly — the more you pick, the more the plant produces. Do not let pods become hard and starchy.
Collect elderflower heads for cordial and lemonade. Pick on a dry sunny day when flowers are fully open and aromatic.
Harvest lavender just before fully open for the strongest fragrance. Dry in small bundles hung upside down.

Frequently asked questions
What can I harvest in June in Czech Republic? ▼
June is the start of the main harvest season. You can harvest: lettuce, radishes, early peas, kohlrabi, spinach, strawberries, early raspberries, red currants, cherries, elderflowers (for cordial), chives, parsley, mint, thyme, rosemary and lavender as it begins to flower.
When should I prune a walnut tree? ▼
June is the only correct time to prune a walnut tree in Czech Republic. Walnut trees bleed severely if pruned in winter or spring. Prune after the leaves are fully open in June. Remove dead wood and branches that are crossing or growing inward.
How often should I water tomatoes in June? ▼
Water tomatoes regularly and consistently in June — irregular watering causes blossom end rot and fruit cracking. Water at the base, not on the leaves. In hot weather, water every day or every other day. Consistent moisture is more important than the total amount.
When should I remove tomato side shoots? ▼
Remove tomato side shoots (zálistky) weekly throughout the growing season. Side shoots grow in the junction between the main stem and a leaf. Break them off when small — below 3 cm. This keeps indeterminate (cordon) tomatoes as a single stem and improves air circulation.
