Here in North Florida, it is not uncommon to see a few citrus trees in a residential landscape. With Florida being the second highest producing state of citrus, it is not out of the normal to see them when you are out and about. They are a great option to keep a lush green aesthetic in your yard. But, what other options are there for the homeowner that wants to add some edible diversity to their landscape? In this article we will be discussing a few of the many edible landscape choices that can add both diversity and a sweet treat to your yard.

A popular edible landscape option is the rabbiteye cultivar of blueberry. The rabbiteye blueberry plant is considered easier to grow for the first time blueberry grower in comparison to the southern high bush cultivar. This cultivar thrives in acidic soils and requires a soil pH of 4.0 to 5.5. When planting, the use of pine bark mulch is a great organic method to satisfy the soil pH requirement. Mixing composted pine bark mulch in the soil and adding additional mulch after the bush is planted will add to the soil’s organic matter over time. Mulching also aids the establishment of young plants and moderates soil temperatures and weed control. For variety selection, mid-to-late season rabbiteye cultivars are best for Northwest Florida, as they are more cold tolerant and less susceptible to lose their flowers and young set fruit in late winter/early spring frosts. Common mid-to-late season rabbiteye’s are ‘Vernon’, ‘Brightwell’, ‘Powderblue’, ‘Tifblue’, and ‘Georgia Giant’. Because blueberry plants are not “self-unfruitful”, they will require more than one variety to cross-pollinate with in order to produce fruit. Two is great, but three plants will also encourage larger fruit set for you and your family to enjoy!

Another option that has steadily grown interest in the Florida Panhandle is the apple tree. There are two known cultivars of apple that are acclimated to the North Florida region due to their low chill hour requirement cold tolerance. This is the ‘Anna’ Apple and the ‘Dorsett Golden’ Apple. Apple trees will perform best in full sun locations of the yard and prefer a well-drained soil. The chilling hour requirement for these cultivars of apple are between 400-600 hours. You will begin to see the fruit ripen in the months of May to June. The ‘Anna” Apple has been compared to the well known ‘Red Delicious” that is best known in northern region of the United States. Planting should occur in early spring and planting holes should be big enough that the root system does not become over crowded from limited expansion space. There is no UF/IFAS fertilizer recommendation for the apple tree because it is not commercially produced in Florida, but generally a fertilizer such as 10-10-10 can be used.

The blackberry is a great choice as well for an edible landscape. There are several blackberry species that are native to Florida. Most blackberries produce thorns on their shoots, but many new cultivars have been developed as thornless. When selecting your planting location, low-lying areas should be avoided to deter from over-flooding of your plants. Blackberries thrive best in well-drained soils and high air flow and should be planted between December to February. Pollination of the plant is very important to ensure the quality and quantity of the fruit produced; blackberries range from self-fruitful to self-unfruitful depending on the cultivar. ‘Apache’, ‘Flordagrand’, and ‘Choctaw’ are a few examples of many blackberry cultivars available. The first year after the blackberry has been established, it will only produce new shoots with no berries. These shoots are called primocanes. The second year, berries will produce on these shoots and then be called floricanes. It is important to cut the tip off the primocanes after they have reached about 3 ft in height to encourage the shoot to create lateral branches. Floricanes will die off after they have produced fruit. Trellises can be used as well to encourage the plant to grow upright and off the ground.

The Blackberry

When you think of fruit production in Florida, blackberries (Rubus spp.) will not quickly jump to mind. Many people envision viny plants infiltrating your gardens and attacking you with their tiny spines. These are dewberries and are not known for large or consistent fruit. Though scientifically of the same name, bush varietals are a world apart. Bush blackberries fall into the rosaceae or rose family. They are deciduous fruiting shrubs, generally acclimatized to temperate environments. Luckily for us, they grow in the Panhandle. They’ve not taken off as an agronomic crop large scale due to the brittle nature of their fruit. However, with estimated production rates of 6000lb per acre many parts of the country, their value in home food production is undeniable.

Which to Pick

The University of Florida has been heavily breeding blackberries, but as with all gardens, plant selection is vital. The most critical factor in selecting blackberries is the chill hour requirement. You may recall that chill hours are the total time below 45 degrees a plant needs to set fruit the following spring. The vast majority of our area gets 660-700 chill hours per year on average, with the extreme north end getting upwards of 800 hours yearly. Once this is determined, the focus shifts to growth habit. Many grow erect and will not need trellising, but there are cultivars that vine and will need support. A final consideration for cultivar selection is whether or not they will need pollinator plants as an accompaniment. If the berries you want have this need, pick a compatible cultivar with a similar bloom time. Some cultivars that will do well in north Florida include ‘Arapaho,’ ‘Chickasaw,’ and ‘Choctaw.’

Planting and Care

Plant blackberries over the winter months much as you would any deciduous fruits. If you must store the plant before planting, keep the roots moist if you will be holding the plant for any amount of time. Ensure the first main root is just above the soil line, and remove any air pockets as you backfill the planting hole. Keep the soil moist but not overly wet, and avoid overhead watering. Space the plants according to their full size, which varies based on cultivar. These have shallow root systems and are therefore not heavy feeders. As a result, apply nutrients in the spring of the year they’re planted at ¼ pound per plant. In subsequent years apply ¼ to ½ a pound per plant twice a year. Irrigation and weed control will also be critical in their first year. Irrigation will become less important once the shrubs establish in their location.

Growing food in your home landscape is a great way to reconnect with your property and bring your food system as local as possible. Blackberries are low-maintenance fruit that, once established will provide years of production with minimal effort. For more information, see this Ask IFAS document. Contact your local extension agent for additional information on this and any other topic regarding your gardens.

Native Bees – Important Pollinators

Native Bees – Important Pollinators

The oncoming of spring is heralded by several events. Wildflowers bloom, temperature rises, and insects awaken from their wintry slumber. The latter of these is the impetus for this article. I’m sure you have heard the buzzing of the bees already, but there is more to come. Florida is host to 315 species of native bees in addition to honey bees (Apis mellifera) which are a non-native species. Native bees in Florida are separated into six families, fulfilling several niches within our landscape. This article is only focused on a few of these.

The Sweat Bees

The sweat bees fall into the family Halictidae. These vary greatly in appearance and size with the majority being very small. Often metallic black, but may also be seen in shades of green, blue, or purple they are hard to miss in your landscape. Most sweat bees are ground nesting though some can be found above. Wildflowers, stone fruits, and sunflowers are the primary nectar sources for these bees particularly in early spring.

Bumble Bees

Bumble bees (Bombus spp.) are in the family Apidae. Ground dwelling, the queen overwinters in the soil emerging in early spring to feast on wildflower nectar. Often mistaken as carpenter bees (Xylocopta spp.), they are distinguishable by the hairs covering their bodies which are lacking in carpenter bees. They are one of two bee species seen carrying pollen sacks, honey bees being the other. All but one of the five species in this genera may be found in the Panhandle where they are important pollinators for many native and ornamental plants.

Mason Bees

One of our more unique species, Mason bees of family Megachilidae live above ground lining their nests with mud. Solitary by nature, these are prominent pollinators of fruit trees and blueberries. A variety of color makes them difficult to even identify as a bee. They often come in dark blue, black, or white striped. Much like honeybees, some species of mason bees are purchased from online sources specifically for orchards.

Carpenter Bees

Carpenter bees are the final subject covered here and are split into two subfamilies. Large carpenter bees (Xylocopta spp.) chew their nests into solid wood. That the wood is sometimes fence posts, water tanks or your home means that this insect may be an economic pest. These are large and as mentioned above often mistaken for bumble bees. Small carpenter bees (Ceratina spp.) are differentiated mainly by size as they are much smaller than the large carpenter bee. They may be a variety of colors as well and nest by hollowing out the pith of broken or burnt plant stems. As they make their nests in already broken plant tissue, they are not considered of economic importance.

Conclusion

Native bees are an important part of pollination in the Florida Panhandle. It is worthwhile to get to know which species are active in your landscape. Provide habitat and nectar to them, and they will help your plant life bloom.

Landscape Lessons from Recent Freezes

Landscape Lessons from Recent Freezes

There are important landscape lessons to learn from recent, early and widespread freezes.

First, know the average climate for the region you live in here in Florida. The work has already been done for you with the USDA Plant Hardiness Zone Map. Here is a link for the map: https://planthardiness.ars.usda.gov. Find your zone on the map. Note that Northwest Florida includes zones 8a, 8b and 9a.

The newest map, with interactive features, was updated in 2012.

This map is based on the average annual minimum winter temperature and is divided into 10°F zones. It can help you determine which plants are most likely to thrive in your zone. There are areas bordering Alabama, located in the extreme northern portions of Escambia, Santa Rosa, Okaloosa, Walton and Holmes Counties, that are in Zone 8a, with an average annual extreme minimum temperature of 10 to 15 degrees F. Most of these counties fall within zone 8b, with an average annual extreme minimum temperature of 15 to 20 degrees F. The extreme southern portions of these same counties (bordering the Gulf) are in Zone 9a with an average annual extreme minimum temperature of 20 to 25 degrees F. As you go south in Florida, you move into Zones 9b, 10a, 10b, and 11a. Zone 10b has an average annual extreme minimum temperature of 35 to 40 degrees F. Zone 11a; which includes a small portion of West Palm Beach and Fort Lauderdale, most of Miami and all of the Florida Keys; has an average annual extreme minimum temperature of 40 to 45 degrees F.

Most of the Panhandle is in USDA Hardiness zone 8b.

It seems that some people move to extreme north Florida and think they are in extreme south Florida. They move barely below Alabama or Georgia and want to plant the palms, citrus and tropical plants that thrive in extreme south Florida. If you live in Zone 9a, perhaps you might get by with growing a few plants that are well suited for 9b. But it is wise to mostly grow plants that are known to flourish in the Plant Hardiness Zone where you live. 

Secondly, follow principle one, which is Right Plant, Right Place, as explained in the UF/IFAS Extension Florida-Friendly Landscape™ (FFL) Program. Following this principle results in developing a healthy, low-maintenance landscape by using Florida-Friendly plants that match your site’s soil, light, water and climatic conditions and that require limited supplemental irrigation, potentially less fertilizer and fewer pesticides.

More information on the FFL Program is available through this UF/IFAS Extension link (https://ffl.ifas.ufl.edu) or from the Extension Office in your County.

Using these tools may be a great goal for 2023 as we replace cold-injured plants.
