Basic Bulb Forcing
Welcome - Today, I'm happy to share a simple methodology for bulb forcing using pre-cooled bulbs. This process can help in preventing common problems and make the entire experience much more efficient.
When you think about planting bulbs in the fall, these bulbs have typically been harvested from fields in the summer. As they are planted in the fall, they enter a phase called 'rooting.' This involves a few weeks of cool temperatures underground, allowing the bulbs to establish the necessary infrastructure they'll need for spring growth.
As winter sets in, the ground freezes—particularly in cold climates like ours—and the bulbs enter dormancy until spring arrives. However, the bulbs I'm dealing with didn't get that nice fall rooting period. They've been in storage, receiving all their winter cooling time in the warehouse, but without any opportunity to develop roots.
To compensate, I must give them an artificial fall period to ensure robust growth. This involves planting the bulbs in soil-filled crates and placing them in a cool, dark area. The temperature should be around 40-50 degrees Fahrenheit. After a couple of weeks, once they've developed roots, I can then move them into a warmer space like a greenhouse or a grow room, with temperatures between 60 and 70 degrees.
This approach is crucial because many people mistakenly believe that pre-cooled bulbs are ready to grow immediately. However, they still need a fall period, whether naturally provided or simulated after their pre-winter cooling.
Today, I'm working with various bulbs, including wood hyacinth and the intriguing nectoral scortum, known for its unique, bell-shaped flowers. I'm also planting three types of allium: forelock, globemaster, and pinball wizard, as well as some traditional hyacinths and Leucojum. I'm eager to see how these varieties perform this spring, hoping for a wider range of flowers earlier than usual.
Thank you for joining me on this gardening journey! Should you have any questions, feel free to reach out. I wish you all a wonderful weekend. Happy planting!
