June

In The Fruit Garden This June

June is a crucial month in the fruit garden: plants are growing fast, fruit is setting, and problems can spread quickly in warm weather. A bit of regular attention now makes a huge difference to summer harvests.

🍒Net soft fruit before birds find it

As strawberries, currants, cherries, and blueberries begin ripening:

  • Use proper fruit netting early.
  • Keep nets taut so birds don’t get trapped.
  • Check daily if wildlife can access them.

Birds can strip a crop surprisingly fast once fruit colours up.

💧Water consistently during fruit swelling

Irregular watering causes:

  • Split cherries
  • Bitter strawberries
  • Poor raspberry crops
  • Dropping fruitlets

Best approach:

  • Deep watering once or twice weekly
  • Mulch afterwards to retain moisture

Container-grown fruit needs especially close attention in June.

🪵Mulch generously

Mulching helps:

  • Retain moisture
  • Suppress weeds
  • Improve soil
  • Reduce disease splash onto fruit

Excellent mulches:

  • Garden compost
  • Well-rotted manure
  • Straw under strawberries
  • Leaf mould

Keep mulch slightly away from stems and trunks.

🍏Thin apples and pears

After the “June drop” (natural fruit shedding), thin crowded fruits.

Aim for:

  • One healthy fruit every 10–15 cm on branches

Benefits:

  • Larger fruit
  • Better flavour
  • Reduced branch breakage
  • Improved next year’s cropping

Remove damaged or misshapen fruit first.

🍓Protect strawberries from rot

As fruits swell:

  • Lift fruit off soil using straw or mats
  • Improve airflow
  • Pick ripe fruit promptly

This greatly reduces grey mould in damp weather.

🍐Summer prune trained fruit trees

June is ideal for:

  • Espaliers
  • Cordons
  • Fans

Trim vigorous new growth to:

  • Let in light
  • Improve ripening
  • Keep shape manageable

Avoid heavy pruning of standard trees now.

🪢Tie in raspberries and blackberries

Fast growth can become chaotic quickly.
Secure canes before wind damage occurs.

For summer raspberries:

  • Tie new green canes separately from fruiting canes if possible.

🫐 Feed hungry fruit crops

Container and soft fruit benefit from feeding now.

Good options:

  • Tomato feed (high potash)
  • Seaweed feed
  • Homemade comfrey feed

Especially useful for:

  • Strawberries
  • Blueberries
  • Gooseberries
  • Currants
  • Fruit in pots

Avoid excessive nitrogen or you’ll get leaves instead of fruit.

🍂Watch for common June pests and diseases

Common issues include:

  • Aphids on soft fruit
  • Gooseberry sawfly
  • Codling moth
  • Peach leaf curl
  • Brown rot
  • Mildew

Check plants regularly:

  • Under leaves
  • Around new shoots
  • On developing fruit

Early action is much easier than fixing a large infestation.

🫐Protect blueberries properly

Blueberries need:

  • Acidic conditions
  • Consistent moisture
  • Rainwater if possible in hard-water areas

Mulch with:

  • Pine needles
  • Bracken
  • Ericaceous compost

🍓Remove strawberry runners

Unless you want new plants:

  • Snip runners off regularly.
  • This keeps energy focused on fruit production.

If propagating:

  • Peg only the strongest runners into pots.

🍒Pick fruit frequently

Regular harvesting:

  • Improves flavour
  • Prevents rot
  • Encourages continued production

June harvesting may include:

  • Early strawberries
  • Honeyberries
  • Cherries (warmer regions)
  • Early currants

🪴Keep fruit cages ventilated

Dense growth and warm damp weather can trigger fungal disease quickly.

Thin congested growth in:

  • Gooseberries
  • Currants
  • Tayberries
  • Jostaberries

Good airflow is one of the best disease preventatives.

This Month's Key Tips
  • Hoe borders regularly to keep weeds down.
  • Be water-wise and keep plants hydrated.
  • Pinch out sideshoots on tomatoes.
  • Prune spring flowering shrubs.
  • Mow lawns weekly.
  • Shade greenhouse to keep cool and prevent scorch.
