Growing Onions in Northeast Florida
QUESTION: I started my onions this month and they really have not done much. What could be wrong? HB
JORDI: I will need to see some of the plants to determine what might be wrong. Please call the office to determine a good time to bring in your specimen. If your soil has not been tested within the last 2-3 years, it might be wise to pick up a soil test kit at the Nassau County Extension office, the cost is only $7.
Generally, bulbing onions should be started in the fall and transplanted in January through February. However, do not give up — it is possible you will see some results soon. I would also suggest you consider planting clumping onions, which can be put in anytime between August and March.
Onions are not difficult to grow but the University of Florida has a limited number of choices suggested for our area. Consider choosing short day bulbing onions such as Granex (yellow) for the best results when desiring bulb onions. Opt for Evergreen Bunching or White Lisbon Bunching for bunching onions. Shallots are considered multiplying onions. If you want to plant leeks choose American Flag.
QUESTION: A friend just brought me a cyclamen. What can you tell me about this pretty plant? MH

JORDI: Cyclamen plants have exotic looking flowers but the leaves are also stunning – such a pretty plant. However, they are a little finicky about their environment. They prefer evening temperatures between 40 – 50 degrees F, day time temperatures should not go over 70. This makes cyclamen a great plant to help us out of the gray doldrums of the long stretch between January and March. It is possible to put the plant outside as long as you bring it back inside or cover it up when temperatures drop below forty.
Cyclamen also prefers good air circulation and moisture in the air which makes it a poor choice as a year round house plant. Evidence it is unhappy with the environment is yellowing leaves, which eventually drop off. In addition, cyclamen does not like wet soil. The soil must be well drained. This is probably why it does not last from one season to another here in Florida as we always have one or two rainy seasons during the late spring and summer. The most common problem is overwatering which causes the tubers to decay. Mites can be an issue for cyclamen and violets which can best be controlled by horticulture oil.
I would treat cyclamen like a cool season annual. Enjoy the beautiful leaves and flowers for the length of time you have it. When selecting one from the retail nursery, be sure to pick one with loads of unopened buds to provide the optimum amount of flowers.
QUESTION: I would like to have plants which will provide food for wildlife in the winter. What would you suggest? CM
JORDI: The best environment is a allowing a natural buffer between houses and subdivisions. Saving large stands of trees and clumps of green space enable native plants the ideal environment to flourish. Wildlife has a place to nest, feed and hide. In these green spaces, it is vital to remove any invasive plants as they reproduce so quickly they disrupt the natural food chain balance. Adding clusters of native plants to your own landscape will also be of benefit. Most of the local plant nurseries carry a variety of native plants and we have one native plant nursery here too. However, it is important also to note a plant does not have to be native in order to provide sufficient food or shelter. Good plant choices are red cedar, Virginia Creeper (this is not an invasive vine), and staghorn sumac.
