How to Grow Potatoes Organically: Healthy, High‑Yield Harvests
Growing potatoes organically is easier than many gardeners think. With the right soil preparation, feeding routine, and organic care, you can enjoy abundant, chemical‑free harvests straight from your garden or allotment. One of the best ways to boost growth naturally is by using plant‑based fertilisers such as those from Natura Grow, which provide nutrients without compromising soil health or the environment.
In this guide, we’ll walk through the key steps to growing potatoes organically — from planting to harvest — and explore how Natura Grow’s organic, bio‑active fertiliser range can help you grow stronger, more productive plants.
1. Choose the Right Spot and Prepare Your Soil
Potatoes thrive in light, fertile, well‑drained soil. Work the ground deeply, removing stones and breaking up clumps. Organic matter is essential for healthy tuber development, and this is where a soil‑enriching fertiliser such as Natura Grow All-Purpose Feed or Pellet Fertiliser can be especially helpful.
These products are entirely plant‑based, chemical‑free, and naturally bio‑active, improving soil structure and boosting beneficial bacteria that help crops resist disease.
Because the fertiliser is created from energy crops grown in Cambridgeshire and processed through anaerobic digestion, it’s also sustainably produced and carbon‑friendly — a perfect match for organic growing.
2. Plant the Seed Potatoes
Once the risk of frost has passed, plant seed potatoes 10–15 cm deep and around 30 cm apart. If planting in rows, space rows about 70 cm apart to allow good airflow. As shoots begin to appear, regularly “earth up” by mounding soil around the stems. This prevents green potatoes and encourages more tubers to form.
3. Feed Organically for Strong Growth
Potatoes are hungry crops, especially as they form tubers. Liquid organic feeds are excellent for delivering nutrients quickly, and Natura Grow Fruit & Veg Liquid Feed is an ideal option.
This fertiliser is:
✅ 100% plant‑based and vegan,
✅ rich in beneficial bacteria,
✅ free from chemicals, animal by‑products, and peat,
✅ and effective for improving soil fertility and boosting crop health.
It provides nitrogen, phosphorus, and potassium (NPK 3.5‑1‑8) as well as micronutrients — everything potatoes need for leaf growth, root strength and tuber development.
Mix 100 ml with a standard 4.5 L watering can and apply every 7–10 days during the main growing season.
4. Water Well and Keep Weeds Down
Consistent moisture is essential for preventing scab and ensuring potatoes swell properly. Water deeply but avoid waterlogging. Keep the area weed‑free to reduce competition for nutrients.
5. Harvest at the Right Time
You can harvest “new potatoes” once plants begin to flower. For larger maincrop potatoes, wait until the foliage yellows and dies back. Lift carefully and allow the tubers to dry before storing.
