Choosing the Right Egg Cartons
Use only plain cardboard or recycled paper egg cartons. They should be uncoated and free from plastic or wax.
Avoid:
- Plastic egg containers
- Styrofoam cartons
- Wax-coated cartons
- Colored or glossy packaging
You can poke small drainage holes in each cup before placing the cartons in the trench, especially if your soil holds too much moisture.
Ideal Planting Depth
A useful rule is to plant bulbs at a depth of about two to three times their height.
Examples:
- Tulips and daffodils: 12–15 cm deep
- Crocus and muscari: 6–8 cm deep
- Hyacinths: 10–12 cm deep
- Small iris bulbs: 6–8 cm deep
Tips for Healthy Blooms
- Choose firm bulbs with no mold or soft spots.
- Plant spring-blooming bulbs in autumn.
- Plant summer-blooming bulbs in spring after frost.
- Improve heavy soil with compost.
- Place bulbs pointed end upward.
- Water deeply once after planting.
- Add mulch to protect the soil.
- Leave green foliage after blooming until it turns yellow.
Common Mistakes to Avoid
- Planting bulbs too shallow
- Using plastic cartons
- Overwatering during winter
- Planting damaged or moldy bulbs
- Using poorly drained heavy clay soil
- Cutting foliage immediately after flowers fade
