Why Grow Bishop’s Balls?

Bishop’s Balls can serve various purposes in your garden or patio:

Starting from Seeds

Seed Collection or Purchase

If you wish to grow Bishop’s Balls from seed, you can either collect seeds from your own plants or purchase them from a reputable source. When collecting seeds, ensure they are fully mature, typically brown and dry on the plant.

Germination Process

  1. Preparation: Start by soaking the seeds in water for about 24 hours before planting. This helps to soften the hard seed coat and increases germination rates.

  2. Sowing: Use a well-draining potting mix. Sow the seeds about 1/2 inch deep in seed trays or small pots. Space them adequately to allow for growth.

  3. Conditions: Place the pots in a warm location with indirect sunlight. The ideal temperature for germination is between 20-25°C (68-77°F). Keep the soil moist but not waterlogged.

  4. Germination Time: Seeds typically take about two weeks to germinate, although this may vary based on environmental conditions.
