Forcing crocuses on pots
Like hyacinths and tulips, crocuses have also probably been forced for centuries. Most likely on pots with soil and on small crocus vases filled with water. Hardly any information can be found about how long the forcing on the typical crocus pots with the holes on the sides has been practised. Forcing crocuses on these types of pots, looks however much nicer when one can watch the shoots growing out of the holes.
Different types of crocus pots from various countries. The pots are shown here in old daffodil boxes, painted white.

How to force crocuses
The process of forcing is simple. The bulbs are planted on a good potting or garden soil. Pots with a drainage hole like most French crocus pots have, can also be planted in the garden. Start with putting some soil in the pot to obtain enough support for the bulbs to be placed in front of the holes. The young shoots should of course stick out of the holes. Fill up the pot with soil completely and plant also some bulbs in the top opening of the pot. The bulbs (corms) can be forced after a cold period of about 13 – 15 weeks.
Get the most out of it
Before bringing the pots in from the cold, the sprout length should be no longer than about 5 cms (2 in). The temperature during this cold period should not be much higher than 9ºC (48ºF). Further there are many similarities with the forcing of hyacinths (for more information about culture, see chapter: forcing hyacinths on vases ). Beware of mice! Crocuses are even more appreciated on the menu of these little animals than tulips, whereas luckily, daffodils and hyacinths are not at all popular with them.
Best for forcing are the big flowering white, blue and striped varieties, which can be used for flowering from January. The yellow crocus is more difficult to force and is best used a month later.
It is all French here: a crocus pot and two footed, ruby/cranberry red hyacinth vases.

A big bulb pot planted with large flowering crocuses and narcissus (= daffodil) Tête à Tête. The three pictures show crocuses starting to flower, a week later both crocuses and daffodils show their flowers and in the third week crocuses are withered and only the Tête à Tête daffodils are flowering. Altogether four weeks of spring in winter!

A Rimac crocus pot with Ornithogalum fimbriatum back at our home by the window. I have cultivated this fairly rare bulb for many years myself, and it is very suitable for pots because it stays very short. A period of cold is required beforehand.
