Summer’s on its way
As bulbs fade and herbaceous borders grow in leaps and bounds, it is now clear that summer is approaching. Sowing and planting out tender vegetable seedlings can begin, depending on regional weather variations, and you can take softwood cuttings.

June
Summer arrives
June 21 is the longest day of the year, and the extra light and warmth encourages the allotment to put on an exuberant burst of growth. But this extra light and warmth also means weeds will sprout up from seemingly nowhere. Keep on top of them by hoeing regularly in dry conditions.
Top jobs this month
- Hoe beds regularly to keep down weeds
- Be water-wise, especially in drought-affected areas
- Pinch out sideshoots on tomatoes
- Harvest lettuce, radish, other salads and early potatoes

July
Summer is progressing
This is often one of the hottest months of the year and a great time to sit out and enjoy your allotment. Keep plants producing by regularly harvesting, and you’ll enjoy a longer cropping period. Make sure you keep new plants well watered, using grey water where possible, and hoe off weeds, which thrive in the sunshine.
Top jobs this month
- Water tubs and new plants if dry, but be water-wise
- Pick courgettes before they become marrows
- Treat apple scab
- Order catalogues for next year’s onion, garlic and shallot sets
- Harvest apricots, peaches and nectarines
August
Sultry late summer
August is usually one of the hottest months of the year – making watering essential. Try to use grey water wherever possible, especially as water butts may be running low if it has been a dry summer. August is traditionally holiday-time, so you might need to enlist the help of friends and family to look after the allotment while you are away.
Top jobs this month

September
Late summer progresses into autumn
September is generally a cooler, gustier month than August and the days are noticeably shorter. You’ll be busy reaping the rewards of all the previous hard work and harvesting your crops. Make the most of the remaining warmth while you can!
Top jobs this month
- Pick autumn raspberries
- Dig up remaining potatoes before slug damage spoils them
- Keep up with watering of new plants, using rain or grey water if possible

October
The autumn chill sets in
Although we had some warmer days over September, the autumn is now definitely here for real, and it feels colder. It’s a beautiful time of year, with the trees changing colour. Sometimes it may seem pointless raking, when the wind blows even more leaves onto the ground, but just think of all the lovely leafmould you can make! It’s also time to start preparing for early frosts.

- Harvest apples, pears, grapes and nuts

November
Winter is on its way
Leaves are falling rapidly, and wind and rain are on the increase. Tender plants will need protecting from frost, gales and freezing rains. Move plants into a sheltered spot, but if you can’t, it is worth wrapping plants or pots. Remember winter can be a tough time for birds in terms of water and food, so keep supplies well topped up.

Winter frost
