Some advanced companion planting ideas – a sponsored guest post by D. T. Brown Seeds.
For seasoned gardeners, companion planting isn’t just a handy trick—it’s an essential strategy for optimising yields and creating a thriving, resilient garden. By pairing specific plants together, you can naturally repel pests, improve soil fertility, and even enhance the flavours of your crops.
If you’re ready to level up your vegetable patch, let’s explore some advanced companion planting combinations and tips. From vegetable seeds to blooming flowers help your plants take root.
Why Companion Planting Works
The principle of companion planting is simple: some plants work better together than others. The benefits include:
- Pest Control: Strongly scented plants like herbs can mask the presence of vegetables, confusing pests.
- Soil Improvement: Legumes fix nitrogen, while deep-rooted plants break up compacted soil.
- Efficient Space Use: By intercropping, you can maximise harvests without overcrowding.
For experienced gardeners, companion planting offers a way to fine-tune your growing techniques, making your garden more productive and eco-friendly.
Advanced Companion Planting Combinations
1. Tomatoes and Asparagus
Asparagus roots repel nematodes that can damage tomatoes, while tomatoes deter asparagus beetles. For extra pest control, add parsley nearby—it attracts beneficial insects like parasitic wasps.
Tip: Plant asparagus and tomatoes in alternating rows to optimise airflow and light.
2. Brassicas and Dill
Cabbage, kale, and broccoli benefit from dill, which attracts lacewings and ladybirds—natural predators of aphids and cabbage worms. The dill’s strong scent also deters pests like cabbage moths.
Tip: Allow some dill to flower for maximum insect attraction.
3. Beans, Corn, and Pumpkins (Three Sisters)
This traditional combination works beautifully: beans fix nitrogen in the soil, corn provides a natural trellis, and pumpkins shade the soil, suppressing weeds.
Tip: Add nasturtiums to the mix to attract aphids away from your crops.
4. Potatoes and Horseradish
Horseradish repels Colorado potato beetles and improves the resilience of nearby potato plants.
Tip: Plant horseradish at the corners of your potato bed, as it can spread aggressively.
5. Onions and Carrots
Onions deter carrot flies, while carrots help break up the soil for onion roots.
Tip: Thin carrots early to prevent overcrowding and improve airflow.
Common Pitfalls in Companion Planting
- Overcrowding: Too many plants in one space can lead to competition for resources.
- Timing Issues: Fast growers, like radishes, can shade out slower crops.
- Incompatible Pairings: Some plants, like onions and beans, inhibit each other’s growth.
Solution: Plan your layout carefully, considering each plant’s growth habits and needs.
