The exact number of petunias you can fit in a hanging basket depends primarily on the size of the basket. Based on the provided reference, we can determine the quantity for a specific size.
According to the text "Growing in hanging baskets":
A 30cm hanging basket will take 3 or 4 petunia plants and there might just be enough room for a few trailing lobelia for added effect.
Petunia Planting Guide for a 30cm Basket
For a standard 30cm (approximately 12-inch) hanging basket, the recommendation is to plant 3 or 4 petunia plants. This allows enough space for the plants to grow and trail effectively throughout the season.
Factors Influencing Petunia Count
While the reference gives a specific number for a 30cm basket, the ideal quantity can vary based on several factors:
- Basket Size: Larger baskets can accommodate more plants. A smaller basket would require fewer.
- Plant Variety: Trailing varieties like 'Wave' petunias, mentioned in the reference for their extensive growth (up to 120cm or 4 feet), might need slightly more space than bushier, more compact types.
- Desired Look: If you want a very full, overflowing basket immediately, you might plant slightly more, but be mindful of overcrowding. For sustained healthy growth throughout the summer, sticking to the recommended density is best.
What to Expect from Trailing Petunias
The reference highlights the Wave variety of trailing petunias, known for their vigorous growth and long cascades of color. Planting 3 or 4 of these in a 30cm basket, potentially with some trailing lobelia as mentioned, can create a stunning display that lasts all summer.
To ensure your petunias thrive, remember they generally require regular watering and feeding, especially in containers.
Recommended Planting Density
Based on the reference:
| Basket Size | Recommended Petunias | Additional Notes |
|---|---|---|
| 30cm | 3 to 4 plants | Room for other trailing plants like lobelia |
This table summarizes the key information from the reference regarding the number of petunias for a common hanging basket size. Choosing the right number of plants is crucial for healthy growth and a spectacular summer display.
