Egg cartons space bulbs perfectly, every time

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.
