Insects Take a Break in Winter, Which Will Soon Be Over !

A common question about insects when cold temperatures arrive is whether or not the cold will kill many pests. Although temperatures will occasionally drop below freezing in north Florida, it is normally not cold enough to significantly impact insect populations for the upcoming year.

Even when we do receive a significant amount of cold weather, insects have many methods to survive weather changes. Some insects survive by moving to micro-habitats that are more resistant to temperature fluctuations. Beetle larvae may move deep in the soil or into logs and trees for protection. The grubs can continue feeding on decomposing material throughout winter months. Beneficial insects such as dragonflies and damselflies stay protected in their nymph forms in the mud of ponds and lakes.

One of the most famous insect survival strategies is migration. We are all familiar with the late summer and fall flights of the monarch butterfly to warmer regions of Mexico and southern California. Those butterflies and moths that do not migrate have their own survival techniques. They will overwinter in protective pupal cases to emerge as adults in the spring. Moth cocoons are spun of silk and may be composed of multiple layers, making them a good protection for the transforming insect.

Insects are adapted for survival and can live through far colder winters than we experience. Even though our cold weather will not drastically change insect populations, periods of cold will at least slow down their activity enough for us to enjoy a break from many pest worries.

 

 

 

The ‘Star’ of Magnolias

The ‘Star’ of Magnolias

Magnolias are well known plants to gardeners and many are familiar with the foliage and flowers of these plants. If you are looking for another earlier bloomer, you may want to consider adding a specimen selection to your landscape, the Star magnolia (Magnolia stellata).

 

Although not native to the United States, star magnolia is a slower growing multi stemmed deciduous shrub reaching about 15 feet in height over time. The best feature are the bright whitish pink star-shaped blooms appearing in late winter before leaves emerge.  The flowers offer gardeners a peek of the spring to come and remind us that our Gulf Coast winters are not that long. DSC_0065

Plants do best in soil with some organic amendments and mulch over the root systems. A planting area that receives a little afternoon shade is ideal but established plants will adapt to sunnier locations when irrigation is provided during drier weather.  Only occasional pruning is required to remove crossing branches or those that grow out of bounds.  Prune after flowering if needed.

Still Time for Parsley

Still Time for Parsley

Parsley is one of the most well-known herbs, and if you missed the fall planting, there is still time to choose a preferred selection for late winter/spring planting.

An herbaceous biennial, parsley is an easy herb for containers or small garden spaces. You may purchase a small pot at the nursery or grow from seed.  Realize that seeds do best when soaked in warm water for 24 hours prior to planting and may not germinate for several weeks.  Be sure to mark the area well so you remember not to overplant with another herb or vegetable.

Choose an area or soil that allows for good drainage and full sun in the cooler months. During the heat of summer, parsley does prefer a little break from afternoon sun. Consider planting in pots so plants can be moved during the hottest months.  Plants will prefer water during times when rainfall is lacking, but the taproot does allow the plant to survive some drought.

There are different types of parsley you may choose but the most common types sold in stores are the curled leaf parsley and the Italian parsley. The Italian parsley has a stronger flavor and holds up a little better during cooking.

Parsley is an attractive plant as a garden border or in a mixed container but will likely have a visitor during the warmer season that will feed on the leaves. The black swallowtail butterfly will use parsley as a host plant so plant enough to share with the butterflies.

Too Much of a Good Thing?

Too Much of a Good Thing?

Information on gardening practices is freely shared between gardeners and many times the good advice is helpful in plant selection and improving plant growth. There are some passed along practices that are not always suitable for every situation and gardeners may need to investigate a little deeper before implementing the good advice.

One common recommendation from gardeners is to apply Epsom salts to the soil to improve plant growth. Gardeners may have used Epsom salts for various plants in the garden and viewed plants that appear to grow better or have improved leaf color. Therefore a general recommendation to help others who have some general plant problems or off color leaves is to apply Epsom salts.

Before you apply Epsom salts to your garden, understand that it is an inorganic fertilizer, specifically magnesium sulfate. Plants make their own food but they derive most of their nutrients needed for important functions form the soil. Magnesium is one of the nutrients that is essential in photosynthesis. At times, our sandy soils may be lacking in nutrients but there may be plenty of nutrients available for plants.

The recommendation to apply Epsom salts may sound like a good idea but gardeners should always make sure that magnesium is needed before any applications. Too much magnesium in the soil can interfere with the uptake of other nutrients by plants. You could create more of a problem by indiscriminately applying Epsom salts when magnesium is not needed.

As you hear often from the University of Florida Extension, conduct a soil test before applying fertilizer to determine the major nutrient levels available in your soil. This $7.00 test will help you better manage plant nutrition. If you need assistance interpreting soil test results, contact your local county Extension office.
