We often talk about sandy, nutrient poor soil in Florida and how difficult it is for growing many favorite landscape plants. Gardeners may spend considerable time and money amending soils with organic matter to improve quality.
The low maintenance approach is to embrace your sandy soil and consider plants that thrive in sandy, well-drained soil. One very attractive native shrub that actually prefers this type of soil is false rosemary, Conrandina canescens.
False rosemary is a member of the mint family that is well adapted to drier, sandy soils. It can be found in many coastal communities growing in natural areas. It is easily recognized in the spring and early summer by light purple blooms. Considered a small shrub or groundcover, False rosemary needs full sun. One plant can easily spread out to 4-5 feet in diameter with a height of 2-3 feet.

False rosemary does have aromatic foliage and is attractive to bees. It is a very low maintenance plant once established and its few issues tend to be related to soils with too much moisture and plants being shaded after establishment. New seedlings will emerge around the main plant when growing conditions are right. If you want to try this native plant in your landscape, talk to a local nursery.

The hectic pace to contemporary life can justifiably be compared to the seemingly erratic behavior of insect pollinators. Darting from flower to flower with no apparently logical progression for choice of blooms, all the while emitting a mind numbing buzz.

This incessant and unending grind of bouncing from task to task has created an atmosphere of tedium and monotony which has become the anthem of many adults. As quick as one chore is complete, another replaces it. Russian composer Nokoli Rimsky-Korsakov wrote what might be considered today’s theme song at the dawn of the 20th century. “Flight of the Bumblebee” catches the frantic haste at which this insect functions, as well as its commonly encountered cousin the carpenter bee.
Bumblebees and carpenter bees are very similar in behavior, coloration and size. The easiest way to differentiate these insects is by their abdomen, the body segment furthest from the head. Bumblebees have an abdomen thickly covered in fine hairs. Carpenter bees lack the fine hairs and have a shiny abdomen.
Xyloxop micans Lepeletier, as the large carpenter bee is known scientifically, is one of more than 500 species worldwide. Almost all members of this genus build their nest by burrowing into dead wood. In the wilds of the panhandle this usually means deadfall timber of almost any sort. Unfortunately, in the areas which include human structures, the nesting sites include wooden timbers and siding.
Unlike European honeybees, the carpenter bees are labeled as solitary bees. There may, however, be several nests in close proximity to these active insects.
Nests are composed of a single parent that lays eggs in a segmented tubular nest. The nest openings are a nearly perfect 5/8 inch (16 mm) hole. Each nest has only a single opening, but multiple tunnels will branch off the main passage. These bees do not eat the wood removed to create the nest channels. Sometimes the holes are not visible to the observer, but the wood emits a buzzing or humming sound when these bees are nesting in hidden locations. In many cases small quantities of saw dust can be found on the ground under the hidden nest.
Heavy or repeated infestations can weaken structural timbers and severely damage siding. Decay and breakage will ultimately follow an untreated incursion.
While the damage caused by carpenter bees can be quite expensive, they may attract an even more destructive predator. Woodpeckers, especially the native pileated woodpecker, dine on carpenter bee larvae at every opportunity. These feathery insect assassins are attracted to the vibrations and hums of the bees hidden in wood. In some cases, the wood acts as a resonator and amplified the insect noise which assures an aerial assault. When discovery of the larvae is confirmed, the woodpeckers attack with a ferocity seldom seen in nature. The rapid-fire staccato of their hammering is loud and devastating.
Structural supports are compromised far beyond the damage done by the carpenter bees, and at a quicker rate. Siding is often shredded and left completely useless.
Commonly available insecticides can help control the carpenter bee population and reduce the prospects of woodpecker damage. Unfortunately, this only adds one more item to the long list of chores and task of contemporary adults.

The mining bees or adrenids are often seen in areas of landscapes that have little ground vegetation and loose soil. After mating, the female bee will excavate a very small tunnel in the ground that has several small cells attached to it.

The bee collects pollen and nectar to add to the cell and then lays a single egg in each cell. The emerging larvae feed on the nectar and pollen until it changes to an adult bee in the fall. There is only one generation a year. Although these solitary bees individually produce small nests, sometimes many will nest in close proximity to each other.

Solitary bees are not aggressive and stings are quite mild. Most solitary bees can be closely observed and will elicit no defensive behaviors. Perhaps the most common stings that occur are when the sweat bee, which is attracted to moisture, stings when swatted. Males of some solitary bees, which can not sting, will sometimes make aggressive-looking bluffing flights when defending a territory.
Like the most famous honey bee, solitary bees play a beneficial role in the pollination of plants. Their activity in the spring is short-lived and no management is necessary.

It won’t be long until row crops and vegetable gardens are planted and thriving once again next spring. A sometimes taken for granted, yet critical element of any prosperous crop is successful pollination. Most of us know what “text book” pollination means, but did you know in cucurbit plants, (squash, melon, pumpkin) at least 1,000 grains of pollen must be evenly deposited in each bloom to produce a uniform marketable fruit? Or, to grow our favorite summer delight, each watermelon flower must be visited by a honeybee a minimum of 8 times? And how about the fact that each silk in a corn flower is connected to one kernel on the ear of corn, and for the kernel to develop properly pollen must travel down the silk through a pollen tube to the waiting kernel? Add to these facts the dizzying variety of pollen and flowers, bloom times, pollination dynamics, weather conditions, plant growth, and availability of pollinator insects, then one can begin to see how amazing pollination is, and how critical it is to our food supply.
What are the basics of pollination?
The first step of fruit or vegetable reproduction takes place when flowers emerge. Plant flowers can be male, female, or perfect flowers. The male flowers produce pollen. The female flowers have ovaries which, when fertilized, become the fruit or vegetable. “Perfect” flowers have both male and female parts within a single flower. Most garden vegetables such as beans, peppers, and tomatoes have perfect flowers, whereas cucurbits like squash, pumpkins and watermelon, have separate male and female flowers on the same vine. For successful pollination to occur, the male pollen must reach the female ovaries in order for the fruit or vegetable to be produced.
Methods of Pollinating
Transfer of pollen to the plant ovaries for fruit and vegetable production, whether in the same “perfect” flower, or in another separate female flower, occurs in several ways. Some plants, like corn, depend on wind to transfer pollen to the silk, and ultimately ovaries, of the female flower. Other plants, like squash depend on the help of pollinators like insects to deliver the pollen to the ovaries. Plants that produce perfect flowers can self-pollinate, but still benefit from contact with pollinators. In small backyard gardens, many crops in the cucurbit family (squash, melons, etc.) or those that have separate male and female flowers, can be pollinated by the gardener by hand. In the absence of insect pollinators in dooryard gardens, hand pollination will increase yields.
The Importance of Bees
Obviously, in production agriculture, hand pollination of crops is not feasible, and although some crops are wind pollinated, most crops need insect or animal pollinators to accomplish the job. As we know, bees are one of the most important pollinating insects, and it is well documented that yields of many fruit and vegetable crops increase in both quality and quantity when pollinated by honey bees. According to the UF/IFAS publication Minimizing Honey Bee Exposure to Pesticides:
The Business of Pollination
Because they are so critical to increased quality and quantity yields, managed honey bee colonies are used across the country in a thriving contractual pollination industry. According to the UF/IFAS publication Sample Pollination agreement,
The business of pollination is crucial to the agricultural industry in the United States. In Florida, the major need for pollination is in fruit and vegetable production.
And according to the UF/IFAS publication Minimizing Honey Bee Exposure to Pesticides,
Rental of honey bee colonies for pollination purposes is a highly demanded service and a viable component of commercial beekeeping and agriculture. Bee colonies are moved extensively across the country for use in multiple crops every year. There are also over 3,000 registered beekeepers in Florida, managing a total of more than 400,000 honey bee colonies and producing between 10–20 million pounds of honey annually.

Crop Pollination Requirements
The dynamic of pollination is a fascinating and critical component of both dooryard and production agriculture. Research on plant health, varieties, growth, and potential, as well as research on honey bee colony health and management, all play a role in producing sustainable food yields. The University of Georgia has summarized pertinent literature related to common fruit and vegetable crop pollination requirements (Apple, Blueberry, Cantaloupe, Cucumber, Squash, Watermelon, Other Crops). This comprehensive resource provides the recommended number of beehives per acre for each crop, plus additional information on plant variety characteristics, and other useful information related to maximizing pollination and yield. Check it out: Pollination: Crop Pollination Requirements
So whether you have a dooryard garden or a large farm, it will benefit you to learn all there is to know about your crop’s pollination requirements to maximize yield and quality potential.
