When I select my bulbs I first decide on my color combinations. Then I try to get a variety according to height that the tulip will grow and also whether it will bloom early, mid or late season. This will extend the time you have lovely tulips in your garden.
If you recall I purchased my bulbs at the Garden Club of Houston Bulb & Plant Mart back in October. In the northern regions of the U.S. gardeners plant their tulips in the Fall and the bulbs enjoy their needed cold spell from the cold winters. Since we have mild winters in Texas most tulip bulbs need to be refrigerated for 14 to 16 weeks. This tricks the bulbs into thinking they've gone through a cold winter underground
This is how we have to do it.
I laid a cloth in the bottom of the crisper drawer, deposited my tulips and announced to the world, "NO FRUIT IN THIS REFRIGERATOR FOR AS LONG AS THESE BULBS ARE IN HERE!".
When fruits start to ripen they release a plant hormone in the form of ethylene gas. Ethylene gas is also known as the 'death' or 'ripening' hormone. This is a good thing when it comes to ripening your fruit, like putting avocados in a brown paper bag to make them ripen quicker. However, it is evil for tulip bulbs because the ethylene gas will destroy the flower inside the bulbs.
Ideally, you want to plant the bulbs when the soil is still fairly cool (45° to 50°F) so they have time to establish healthy roots before the ground really warms up they start to poke up through the soil. This can be (and was) a challenge for me because I had to wait longer to plant because it was always raining or muddy, then BOOM it started getting hot. They seemed to have fared well.
I'll re-visit the tulips when I show you what to do when the flowers are gone and the foliage isn't too pretty.
