What to do in July
July is exciting. Your plants will grow like triffids in the warm, long days, edible flowers will bloom, and more crops will be ready to pick - ripening fast in the current heatwave.
It's a busy month... There are peas and tomatoes to tie up, plants to feed, seeds to sow and of course lots of watering - for details of jobs to do and tips to help you, see below.
Luckily the long, warm evenings provide the perfect opportunity to potter outside, catch up with all the growing jobs, and ponder life - and perhaps enjoy meeting and chatting to neighbours while you're at it (see Nine ways food growing can help you meet your neighbours).
On to the jobs for the container garden this month .... here's the list:

On to the jobs for the container garden this month .... here's the list:
-
- Watering
- Feeding
- Sowing and cuttings
- Pruning, tying up, pinching out
- Harvesting
- Wormeries
1. Watering
As the days get warmer and plants get bigger and start producing fruit, they'll need more frequent watering. For ideas on how to make watering your container garden easier see my Guardian article, and for tips on how to keep hanging baskets watered, see here.2. Feeding
New growing media usually contains enough nutrients to support optimum growth for about six weeks - after that your crops will need feeding. And they'll need it most in warm weather when growth will be at at its peak.- Use a liquid tomato feed for all your fruiting crops, once they start flowering and fruiting (see June for more info).
- Mulch hungry crops like courgettes and tomatoes with worm compost if you have it. Not essential but this will give them a nice boost of nutrients and microbial life, and help retain water. Manure or homemade compost is an alternative if you can source some some, perhaps from a city farm. ('Mulch' basically means spreading a layer of an inch or two on top of the soil).
- Water leafy crops with a general purpose organic liquid feed like liquid seaweed, nettle tea, or worm tea once a week.
3. Sowing and cuttings
Salads
Sow salads now if you want to keep up your salad supply in September and October. If you don't have space in your pots, start them in trays ready to move when space appears. (If you find you don't need extra plants, you can always eat the baby salad seedlings as micro leaves!).Leafy Veg
Sow kale, cavelo nero and chard now for autumn leaves and to establish plants to grow over winter.Oriental leaves and fennel
Now is a good time to sow fennel and oriental leaves like pak choi, mustard red giant and mizuna, as they are less prone to bolt than earlier in the year (bolting is when crops start to flower and seed before you want them to)Beans, peas and courgettes
In southern parts of the UK and anywhere where the first frosts cannot be expected until late October / early November, there is time to sow courgettes, runner beans, French beans and peas and get a crop before the first frosts in the autumn (get them in as early in July as possible). In colder parts, where frosts may strike in early October, the chances of getting a good crop a lower.Cuttings
July is a good time to take softwood cuttings (from this years growth) of herbs like lemon verbena, rosemary, Vietnamese coriander, sage, and thyme. This is a great way to expand your herb garden at low cost (free!). You just need to find a friend, neighbour or community garden with a nice herb collection where you can take the cuttings.4. Pruning, tying up, pinching out.
- Bushy plants that cast shade. In a small space it's not uncommon for the leaves of big bushy plants like courgettes to start casting shade on other crops. Sometimes you can move the pots around to reduce the shading. Or you can remove a few of the largest leaves (up to about a third of the leaves) to create light for your other crops.
- Tomato side shoots need constant pinching out to keep them under control.
- Climbing crops like peas, beans and tomatoes usually need constant tying in to ensure they are secure. Double check this if windy weather is forecast. If you having trouble stopping your cane from falling over in the pot, check out this video for an easy way to secure it.
- Pinch out the growing tips of climbers (runners, tomatoes etc) when they reach the tops of their poles. This will encourage them to put their energy into producing fruit.
