Spring flowers can seem an awful long way off when you are confronted with the doldrums of winter. For this reason, forcing bulbs has become a popular way to enjoy colorful blooms well before their outdoor counterparts are budding. The problem with forced bulbs is that they often get leggy and have leaves and stems flopping all over the place. Propping plants in forced jars necessitates a small stake or stick but there are other tricks for keeping forced plants straight and sturdy.
Propping Plants in Forcing Jars and Pots
Whether you are a passionate gardener or just a fan of flowers, forced bulbs can provide an interior display of out of season color and the process is so easy even a novice can succeed. There are numerous tutorials on the process as well as special kits and forcing jars you can purchase to facilitate your flower growth.
However, even professionals are confronted with the problem of nodding narcissus and flopping freesia. Support for forced flowers is necessary to enjoy the beauty of the plants as well as correct growing practices that will help form sturdy, thick stems.
You can choose a regular pot, use a glass bowl with gravel to hold the bulb out of water or purchase a glass forcing vase. The only benefit to purchasing a forcing vase is its curvature. They have a long chimney to support the leaves and stems while the bulb itself is nested below the chimney to allow roots to dangle down into water. This also keeps the bulb out of the water to prevent a common problem, mold.
If you decide to use a regular pot, you will have to consider some sort of forced flower plant support. A regular pot doesn’t have any type of support out of the soil, so you will need to provide a method for keeping forced plants straight. Bulb jar plant support can be unsightly but may be a necessary evil to keep leaves from dangling in the water and stems from drooping over the container.
Types of Support for Forced Flowers
Choosing the right bulb jar plant support is both a matter of taste and function. Depending upon the variety of bulb you are forcing, you may need a long stick or stake or a hoop contrivance to keep multiple stems in order.
For plants that develop one or just a few flowering stems, slender sticks, such as bamboo skewers or Popsicle sticks, may be just the trick. You may need to purchase or make a loose hoop for plants with numerous flowering stems to gather all the blooms into a brace for all the stalks.
Alternatively, you may simply place the bulb on a bed of gravel at the bottom of a tall glass vase with just enough water to cover the root zone of the bulb. This works well as a forced flower plant support for tall specimens, such as tulips, because the walls of the vase will form a prop for the growing leaves and stems. It also allows you to view the plant’s development.
Keeping Forced Plants Straight
One main tip from professional growers of bulbs is to keep the plant out of excessive light during its early development. This is to prevent growth spurts that result in stems that are too slender to support the weight of the flowers. It is also important to provide enough light to minimize the chance of leggy growth that is stretching to reach light.
Another great trick is to use alcohol. Add 1 tablespoon of rubbing alcohol or distilled spirits per gallon of water. The Flowerbulb Research Program at Cornell University discovered that using this solution as the moisture medium in forced bulbs resulted in paperwhites that were 1/2 to 1/3 shorter than those grown in plain water.
Any of the above methods should work for propping plants in forced jars. The actual method will depend upon the presentation you wish and the efforts you wish to undertake.
