BULB CHILLING TULIPS

In warmer areas of New Zealand, tulip bulbs may need refrigeration before planting.

Why? Tulips are native to areas which experience quite cold winters, and they need this cold period for the bulb to complete the development of the flower bud deep inside. An insufficient cold period results in flowers on very short stems or sometimes no flower at all.

Does it affect all types of tulips? Darwin Hybrid tulips are the most suitable types for warmer areas. If you are in a warmer area and want to grow all the colours available in the Single tulip range, the flamboyant Parrot and Peony types, or the graceful Lily tulips, then you will need to do some chilling.

How do I go about chilling? The most important point is that you need to chill, not freeze! Dont put bulbs in the freezer as this is too cold and will kill them. The average fridge is at approximately 4C and this is an ideal temperature.

Are there any alternatives to chilling? A number of things may help you get good tulip flowers without chilling:

All tulips should be planted 15-20cm deep, later in autumn when the soil temperatures are cooler, ideally below 12C. Mid May is an ideal time in warmer areas. Late May for cooler areas.

Avoid planting tulips in pots - pots warm up very quickly, even in winter, when the sun is on them. Bulbs prefer the steady cool conditions in the garden soil. Use a mulch to help keep the soil cooler.

Place the bulbs in a breathable container such as a paper bag and start chilling in early April. You should not start too early as the bulbs are not at the right stage of development for chilling until early April.

Using a paper bag or open container is very important so the bulbs can breathe. Plastic bags cause sweating and will cause mould and rot to develop.

Keep the bulbs to the side of the fridge, not at the back where the cooler plate may ice up and damage them, or where condensation may cause mould to develop.

Ripening fruit, and to a lesser extent, vegetables, release a gas called ethylene. This gas causes other fruit to ripen in a chain reaction. Ethylene can cause severe damage to the developing flower buds in bulbs, often resulting in complete loss of the flower. Dont keep fruit in the same fridge as bulbs, and include an ethylene absorbing sachet in with the bulbs to prevent ethylene damage and suppress mould growth.

These can be purchased here: Ethylene Absorbing Sachet.
