This week’s episode comes from the second week of August, following one of the driest Julys on record. The allotment and kitchen garden are both feeling the strain, with soil baked so hard that water beads on the surface and runs off rather than soaking in. Despite the challenges, progress continues — from experimenting with greywater filtration to planning green manures and keeping established crops alive through the drought.
Allotment Update: Hydrophobic Soil & Survival Mode
The main theme this week is hydrophobic soil — ground so dry and compacted that it actively repels water. Beds have become rock‑hard, making digging, planting and watering difficult. Watering still has to be done by hand with cans, taking up to two hours to give each bed a proper deep soak. It’s heavy work, but essential for keeping established crops alive.
With conditions too harsh for planting out young plants, the focus has shifted to:
Keeping mature crops alive with deep, infrequent wateringDelaying new plantings until the soil can absorb moisture againPlanning ahead by clearing beds for a potato‑specific green manureTidying perennial areas like the gooseberry patch and bramble‑filled cornersPreparing for wetter weather so the site is easier to manage when conditions improveGreen manures have been a success in previous seasons, helping reduce pests and disease, and with blight not yet appearing this year, it’s a good moment to prepare beds for next year’s potato rotation.
Kitchen Garden: Greywater Trials & Practical Housekeeping
At home, the drought has prompted a deeper look at greywater reuse. After a failed experiment using water mint as a natural filter, a more structured filtration system has been tested:
A bucket drilled with holesLayers of gravel, sand, charcoal and strawSome success in removing contaminantsSome soap residues still presentIt’s an ongoing experiment, but a promising step toward making greywater safer for garden use during droughts.
Other practical jobs this week include:
A garage clear‑out, removing broken petrol tools and freeing up spaceA renewed focus on repairable, durable or compostable items to reduce wasteSowing overwintering onions and radish for supporters, though germination is uncertain in the dry soilUsing mulches and compost to help established plants cope with the heatRecipe of the Week: Smoked Sweetcorn & Courgette Salad
This week’s recipe is a vibrant summer dish that makes the most of seasonal produce:
Smoked sweetcorn and courgette salad with chilli butter croutons
Charred sweetcorn and courgetteLime‑honey‑mustard dressingCrisp chilli‑spiced breadcrumbsIt’s colourful, flavourful and pairs beautifully with grilled chicken — a perfect late‑summer plate.
Hydrophobic Soil: Causes, Fixes & Long‑Term Prevention
The episode closes with a detailed look at hydrophobic soil — what causes it, how to fix it, and how to prevent it in future droughts.
Why Soil Becomes Hydrophobic
Organic particles dry out and hardenSoil structure collapsesWater beads and runs off instead of soaking inBeds flood when rain finally arrives because water cannot penetrateShort‑Term Fixes
Repeated light watering with a fine roseLaying damp hessian or cardboard to soften the surfaceBottom‑watering containers to wick moisture upGentle, patient rewetting rather than one heavy soakLong‑Term Prevention
Regular additions of organic matterConsistent mulching with straw, leaf mould or woodchipsAvoiding complete drying by giving a light weekly watering during droughtUsing soil conditioners like coir or biocharAdding shade or wind protection for exposed raised bedsSlow, deliberate watering or drip irrigation to allow moisture to penetrateThese techniques help rebuild soil structure, improve moisture retention and make gardens more resilient as droughts become more frequent.
Outro
Despite one of the driest periods in recent memory, progress continues across both the allotment and kitchen garden. With careful watering, thoughtful planning and a focus on soil health, the garden is still producing — and laying the groundwork for better seasons ahead.
