• Mint: in a separate pot sunk into one front corner, so it can’t spread
Planting black currants and gooseberries together is generally discouraged due to shared vulnerabilities and conflicting environmental needs, despite both belonging to the Ribes genus.
Disease Risk: Both plants are susceptible to gooseberry fire blight and share common pests like the currant moth, increasing the risk of widespread infection and infestation in close proximity.
Moisture Conflict: Black currants require moist soil and thrive in cooler, wetter conditions, whereas gooseberries are more drought-tolerant and suffer from excessive soil moisture or waterlogging.
Pruning Differences: They require opposite pruning strategies; red currants and gooseberries fruit on older wood (2–3 years), while black currants fruit on current year’s growth (1 year).
Mixing care routines can significantly reduce yields.
Recommendation: Plant them separately to manage moisture levels and prevent the spread of shared fungal diseases. If space is limited, ensure adequate distance (at least 6–10 feet) and monitor closely for disease transmission.
You can grow them in one bed, but not all in the same place at the same time. The rational way is to split the bed into a few **zones** by height, spread, and crop life, and to keep the tallest crops on the north side so they do not shade the rest. Sweetcorn and cavolo nero are the main structure crops; French beans, dill, and sweet peas fit as companions or edge crops; mint should be isolated; strawberries want a long-term, low, sunny edge; chicory is best kept in a separate rotation area if possible.
## Best layout
A practical single-bed layout in the UK is:
- North side: sweetcorn in a block.
- In front of or beside the corn: French beans SAXA, only if you are using them as a corn companion and the corn is already well up.
- Outer sunny edge: strawberries.
- Another edge or corner: dill, because it stays relatively small and can be tucked in.
- Separate container or sunk pot: Corsican mint, because it spreads aggressively.
- One end of the bed or a temporary support line: sweet peas.
- Remaining free space: cavolo nero and chicory types, spaced widely enough for mature size.
## What should not be mixed
Mint should not be planted freely in the bed because Corsican mint spreads and is much safer in a pot or root barrier.
Sweet peas and French beans are both climbers, but sweet peas are better treated as a flower support crop, while French bean SAXA is a dwarf bush bean and does not need support.
Chicory and cavolo nero both want more room than herbs or strawberries, so if the bed is tight, they are the first crops to reduce or move elsewhere.
## Spacing guide
Here is a sensible spacing plan from the sources:
| Crop | Spacing / method |
|---|---|
| Sweetcorn | About 45 cm between plants in a block.
| French beans SAXA | About 25 x 25 cm, or seeds 12 cm apart then thin.
| Dill | About 20 cm each way, with rows around 25 cm apart.
| Strawberry 'White Soul' | Start in pots; plant out once established, with generous spacing in the final bed.
| Chicory / Cichorium intybus | Sow shallowly, about 1 cm deep, and keep final spacing roomy.
| Cavolo nero | About 45–60 cm between plants.
| Corsican mint | 6–12 inches apart only if contained, but better in a pot.
| Sweet peas | Sow in modules first, then plant out by a support.
## A sensible sowing order
Start the cool-tolerant and slower crops first, then add the warm-season crops once the soil is warm. Sweet peas can be sown early and planted out once established.
Cavolo nero and chicory can also be started early, while sweetcorn and French beans should wait until the soil has warmed.
Dill is flexible and can be sown directly once frost risk has passed, and strawberries are usually best raised in pots before planting out.
## One-bed plan
If this were my bed, I would do this:
1. Put sweetcorn in a north-side block.
2. Use French beans SAXA only if you have spare space after the corn is established.
3. Put cavolo nero in the widest spacing section.
4. Edge with dill and strawberries.
5. Grow sweet peas on a separate trellis at one end if you have vertical space.
6. Keep Corsican mint out of the bed unless it is in a pot sunk into the soil.
A simple rule is: tall crops north, low crops south, spreading crops contained, and only one or two “big” crops per bed if you want good airflow and easy harvesting.
