Who doesn’t like strawberries, right? Backyard gardeners grow these low-growing herbs throughout the state and there is a significant commercial industry too, as Florida’s climate is ideal for cool season production.
Strawberries like well-drained sandy soils, so they’re a perfect fit for many areas in the Panhandle. Strawberries should be planted in the months of October or November as the plants are quite cold hardy. Shorter days and temperatures between 50°F and 80°F are ideal for fruit development.

Strawberries are also very versatile. You can plant them in the ground, in raised beds or even containers. Transplants should be planted 12” to 18” apart, with 12” row spacing. For best results, use a rich soil balanced with compost and sandy soil and both fertilize and water regularly. Mixing in 2 ½ pounds of 10-10-10 fertilizer into a 10’ x 10’ bed space should be sufficient to start. A sprinkle of fertilizer applied monthly throughout the growing season should also help ensure a solid yield.
Berry production begins to ramp up roughly 90 days after planting, but plants will continue to produce throughout the spring. When the weather gets warmer, the plants start to expend energy into producing runners instead of fruit. These runners will be new fruit producing plants for next season.
Transplants can be purchased from most garden centers. There are many varieties on the market, but “Florida-Friendly” cultivars include “Sweet Charlie”, “Camarosa”, “Chandler”, “Oso Grande”, “Selva”, and “Festival”. “Camarosa” has proven to be the most productive variety in North Florida. Any of these varieties are capable of producing two pints of fruit per plant.
As stated earlier, Florida has a significant strawberry industry and UF/IFAS has a supporting role. The UF/IFAS Gulf Coast Research and Education Center (GCREC) is home to the Strawberry Breeding Program. Cultivars are developed by traditional means, for the Florida commercial industry on an 11,000+ acres research site. Appearance, shelf life, sweet flavor and disease resistance are just some of the areas of selected breading research that is conducted on site. There is also a white strawberry soon to be released!

From time to time we get questions from clients who are unsatisfied with the flavor of the fruit from their citrus trees. Usually the complaints are because of dry or fibrous fruit. This is usually due to irregular irrigation and/or excessive rains during fruit development. However, we sometimes get asked about fruit that is too sour. There are three common reasons why fruit may taste more sour than expected: 1) The fruit came from the rootstock portion of the tree; 2) The fruit wasn’t fully mature when picked; or 3) the tree is infected with Huanglongbing (HLB) a.k.a. citrus greening or yellow dragon disease.
Rootstock
The majority of citrus trees are grafted onto a rootstock. Grafting is the practice of conjoining a plant with desirable fruiting characteristics onto a plant with specific disease resistance, stress tolerance (such as cold tolerance), and/or growth characteristics (such as rooting depth characteristics or dwarfing characteristics). Citrus trees are usually true to seed, but the majority of trees available at nurseries and garden centers are grafted onto a completely different citrus species. Some of the commonly available rootstocks produce sweet fruit, but most produce sour or poor tasting fruit. Common citrus rootstocks include: Swingle orange; sour orange; and trifoliate orange. For a comprehensive list of citrus rootstocks, please visit the Florida Citrus Rootstock Selection Guide. A rootstock will still produce viable shoots, which can become dominant leaders on a tree. In the picture below, a sour orange rootstock is producing a portion of the fruit on the left hand side of this tangerine tree. The trunk coming from the sour orange rootstock has many more spines than the tangerine producing trunks.

Fruit Maturity
Florida grown citrus generally matures from the months of October through May depending on species and variety. Satsumas mature in October and taste best after nighttime temperatures drop into the 50s. Most tangerines are mature in late November and December. Oranges and grapefruit are mature December through April depending on variety. The interesting thing about citrus fruit is that they can be stored on the tree after becoming ripe. So when in doubt, harvest only a few fruit at a time to determine the maturity window for your particular tree. A table with Florida citrus ripeness dates can be found at this Florida Citrus Harvest Calendar.
Citrus Greening
Citrus Greening (HLB) is a plant disease caused by the bacterium Candidatus Liberibacter asiaticus, which is vectored by the Asian citrus psyllid. The disease causes the fruit to be misshapen and discolored. The fruit from infected trees does not ripen properly and rarely sweetens up. A list of publications about citrus greening can be found at the link Citrus Greening (Huanglongbing, HLB).

When asked what kind of citrus to grow here in North Florida, my default response is satsuma. I usually get a funny look, followed by an attempt by the person who’s asking to repeat the name satsuma. The individual may ask, “What is satsuma… is that a citrus?” I guess the person expected to hear orange, grapefruit, lemon or maybe tangerine.
Satsuma is a type of citrus, technically classified as a mandarin and is sometimes referred to as satsuma mandarin. The satsuma mandarin is a good candidate for the North Florida citrus enthusiast for a number of reasons.
Historically, mature dormant trees have survived minimum temperatures of 14°F to 18°F when budded/grafted to a cold-hardy rootstock such as trifoliate orange or swingle, a trifoliate orange cross. Young trees are not as cold-hardy but, due to their smaller size, are more easily covered with a cloth such as a sheet or lightweight blanket for protection during freezes.
Satsuma fruit are ready to harvest October through December, ripening before the coldest winter temperatures. This is not true with most sweet citrus types such as oranges, which are harvested during winter months. Harvesting during winter works well in Central and South Florida where winters are mild but does not work well here in extreme North Florida. The potentially colder winter temperatures of North Florida are likely to result in the fruit on sweet oranges freezing on the tree before they are ripe, potentially ruining the fruit.
Our cooler fall temperatures result in higher sugar content and sweeter fruit.
Fruit are easily peeled by hand, have few to no seed and are sweet and juicy.
Trees are self-fruitful, which means that only one tree is needed for fruit production. This is important where space is limited in a home landscape.
Trees are relatively small at maturity, reaching a mature height of 15 to 20 feet with an equal spread.
Branches are nearly thornless. This may not be true with shoots originating at or below the graft union. Shoots coming from the rootstock may have long stiff thorns. These shoots should be removed (pruned out) as they originate.
Satsuma fruit are harvested in fall but trees are best planted during springtime when temperatures are mild and as soil is warming. Availability of trees is normally better in spring, as well. For additional cold protection, purchase a satsuma grafted on trifoliate orange rootstock and plant the tree on the south or west side of a building. There are a number of cultivars from which to choose.
