Dwarf lilies
Large bulbs such as giant alliums or big decorative lilies may require deeper planting and wider spacing, so they are better planted individually.
Choosing the Right Egg Cartons
Use only:
Plain cardboard or recycled paper cartons
Uncoated and non‑plastic
Avoid:
Styrofoam cartons
Plastic containers
Wax‑coated cartons
You can poke small holes in the bottom of each cup to improve drainage, but this is optional.
Ideal Planting Depth Guide
A general rule:
Plant bulbs at a depth of 2–3 times their height.
Examples:
Tulips & daffodils: 12–15 cm
Crocus & muscari: 6–8 cm
Hyacinths: 10–12 cm
Dig the trench accordingly before placing the cartons.

Tips for Successful Growth
1. Use Healthy Bulbs Only
Choose bulbs that are:
Firm
Mold‑free
Not soft or shriveled
Weak bulbs produce weak flowers.
2. Plant at the Right Time
Spring flowers → plant in autumn
Summer flowers → plant in spring after frost
Cold‑season bulbs need winter chilling to bloom properly.
3. Improve Soil Quality
Mix into the soil:
Compost
Well‑rotted manure
Leaf mold
Good drainage is essential. Bulbs rot easily in soggy soil.
4. Position Bulbs Correctly
Always place bulbs:
Pointed end upward
Flat or root end downward
If unsure, plant sideways—bulbs can self‑correct.
5. Water Thoroughly After Planting
Water deeply once after covering the trench. This:
Settles soil around roots
Removes air pockets
Activates root growth
Avoid constant watering during winter unless the soil becomes very dry.
6. Mulch for Protection
Add a light layer of:
Straw
Dry leaves
Wood chips
This stabilizes temperature and prevents soil erosion.
7. Avoid Fertilizing Too Early
Apply bulb fertilizer or compost:
At planting time (lightly)
Or in early spring when shoots appear
Too much nitrogen encourages leaves instead of flowers.
8. Leave Foliage After Blooming
Do not cut green leaves immediately.
They feed the bulb for next year’s bloom. Remove leaves only after they turn yellow and dry.
Common Mistakes to Avoid
Planting too shallow
Using plastic cartons
Overwatering in winter
Planting damaged bulbs
Heavy clay soil without drainage
