Going on holiday during the growing season feels like betrayal. After fifteen-plus years of growing, the last three on a chalky East Sussex plot, I can tell you that the difference between a plot that survives a fortnight away and one that doesn’t comes down to about two hours of work the day before you leave. Everything you need for the growing year is in our Garden & Outdoor hub. Holiday allotment care is mostly about reducing demand, not adding extra automation.
This guide assumes a typical UK summer holiday — somewhere between five days and a fortnight — and assumes you can’t get someone to come every day. If you can: see a friend, take them a bottle of something, and skip half the fiddly setup below.
The Day Before You Leave: The Real Work
The two hours before you go matter more than anything anyone else does for you while you’re away. The aim is to leave the plot in a state where it needs as little as possible.
- Pick everything that’s ready or close to it. Courgettes the size of a finger, half-flushed tomatoes, beans just starting to fatten — they all keep producing if you pick them, and the unpicked ones often go over before you’re back.
- Pinch out tomato growing tips. Removes any new growth that would otherwise need watering. Same for cucumbers and squash.
- Soak everything deeply. Not a sprinkle — a proper soak. Water the soil, not the plant. Aim for six or seven inches of penetration. If the surface looks dry an hour later, water again.
- Mulch heavily. Anything that breaks the link between sun and soil. Grass clippings, well-rotted compost, cardboard weighted down, straw. Six inches if you’ve got it. Mulch on damp soil; mulch on dry soil bakes it harder.
- Move every pot into shade. Even shade-tolerant plants do better in shade for a fortnight than in full sun without water. Group pots together — they shade each other and slow evaporation.
- Cut grass paths short. Long grass dries fast and tangles things; short grass holds the moisture in the soil better.
- Net the soft fruit. Birds will strip an unprotected row in three days.
Watering Systems: What Actually Works
Three categories, in rough order of effectiveness:
A neighbour or friend
Best by a mile. Even three visits across a fortnight beat any automation. Be specific about what to water and how much (half a watering can per tomato plant; a full can per courgette). Tell them they can have whatever’s ready. Leave a key, leave the watering can full.
A drip system on a tap timer
If you have access to a tap on the plot or in the garden, an automatic watering timer with a drip kit is the most reliable mechanical solution. Set it to run early in the morning for ten to twenty minutes, depending on how many drippers and how dry your soil typically gets. Test it before you leave — set it to fire and watch what happens.
The system works for tomatoes in pots, peppers under glass, and any fixed group of plants. It doesn’t help with beds you’ve planted across, where the drippers don’t reach.
Self-watering spikes and globes
Cheap, mixed results. The plastic spikes that screw onto a plastic bottle work for about three days reliably; after that the rate drops. Useful for individual pots, less useful for an allotment row. Terracotta watering globes work better but only suit pot plants.
The honest summary: none of these systems replace a person, but they bridge the gap when one isn’t possible.
What to Accept Will Be Lost
This is the part most guides skip. A fortnight away in July or August will cost you something. Going in with that expectation makes the holiday less stressful and the return less disappointing.
- Salads will bolt. Lettuce sown in succession is hard to keep going through a hot fortnight unwatered. Accept losing a row.
- Some courgettes will become marrows. Even with a neighbour picking, you’ll find a few football-sized ones in the undergrowth. Use them up in chutney.
- Soft fruit may finish. Strawberries and summer raspberries that ripen while you’re away may go past edible. Birds usually solve this for you.
- Tomatoes may split. Irregular watering causes splitting; coming back to dry plants and a single deep soak guarantees it. Live with it.
- Slugs may have a party. Particularly in damp weather. Bait stations or copper rings around vulnerable plants help; hedgehog-safe slug control is the right approach.
The Day You Get Back
- Don’t water everything immediately. A long, slow soak around root zones is much better than a wash that runs straight off baked soil. Loosen the soil surface first if it’s crusted.
- Pick everything ready. The plant will thank you and start producing again.
- Cut back damage. Yellow lower leaves on tomatoes; bolted lettuce; mildewed courgette leaves. Bin the worst.
- Feed. Plants that have stressed need a nudge to get going again. Liquid feed at half strength is gentler than full strength on a stressed plant.

Holiday season overlaps with the busiest part of the growing year, which is exactly why this preparation matters. July’s full job list is here; August’s here. For the wider summer picture, see the Summer Outdoor hub.
