Cucumbers are a favorite fruit of many gardeners and with a little routine care, you can harvest fresh fruit from your own home garden. Learn some basic information about starting your own cucumbers In the Backyard Garden with UF IFAS Extension Escambia County.
I was recently sent some pictures of some unusual growths on pecan tree leaves. At first glance, the growths reminded me of the galls caused by small wasps that lay their eggs on oak leaves. However, after a little searching it became apparent this wasn’t the case. These galls were caused by the feeding of an aphid-like insect known as phylloxera.

The feeding from the phylloxera causes the young leaf tissue to become distorted and form a gall that encloses this female insect called a “stem mother”. These insects are rarely seen, but the hatch from over-wintering eggs in March/April just after budbreak. Once hatched, these “stem mothers” crawl to the new leaves and begin feeding. Once the gall forms, they start to lay eggs inside the gall. The eggs hatch inside the gall and the young phylloxera begin to feed inside the gall and the gall enlarges. The matured insects break out of the gall in May and some will crawl to new spots on the leaves to feed and produce more galls.

There are two common species of phylloxera that infect the leaves. The Pecan Leaf Phylloxera seems to prefer young trees and the Southern Pecan Leaf Phylloxera prefers older trees. The damage from each of these insects is nearly indistinguishable. Damage from these insects is usually not severe and merely an aesthetic issue.
Once the damage is discovered on a tree, it is too late to control the current year’s infestation. There are currently no effective methods for control of phylloxera in home gardens. Soil drench applications witha product containing imidacloprid have been limited in their effectiveness.
During the COVID-19 crisis, many of us have found that we have more time for activities at home. One activity that can be beneficial to your mental and physical health is gardening. Not only will gardening get you moving physically, but simply being outdoors can help you feel more relaxed during these stressful times. By vegetable gardening, you get the added bonus of becoming more self-sufficient by growing your own healthy food.

To grow vegetables successfully, you will need some basic gardening supplies. This includes seeds or seedlings, fertile soil, gardening tools, and irrigation materials. If you are an avid gardener, you may already have these items at your house. But if you are new to gardening – or if you are simply missing an essential item in your everyday gardening arsenal – where do you go?
Thankfully in Florida, industries regarded as essential during these tough times include food, agriculture, and infrastructure support services. This means farmers, farm workers, farmers’ markets, produce stands, food banks, agribusiness support services, and landscaping services can continue to operate.
But for these essential services to operate safely, they still need to follow social distancing principles to protect the health of both their customers and workers. Therefore, many of our agriculture and horticulture industry personnel are finding ways to adapt. Although this involves making many adjustments, operations such as garden centers and plant nurseries are changing how they function to meet the demand of their customers while remaining safe.

For example, Native Nurseries in Tallahassee has temporarily closed its doors to the public, but they offer pickup and delivery options that are consistent with social distancing guidelines. Customers can either email or call the nursery and provide their contact and billing information, their purchase requests, and specify either pickup or delivery. Pickup orders are placed in a labeled designated parking space for the customer. For a fee, Native Nurseries also offers delivery of purchased items.
If you plan to make a trip to a garden center or plant nursery, call ahead or check the company’s website to learn about its social distancing policies, pickup and delivery options, and any potentially reduced hours of operation.
By continuing to support our local agriculture and horticulture businesses, we can ensure that they can weather this storm and continue to provide us with their essential services long into the future.
So, gather your supplies, stay home, and get your spring and summer vegetable garden growing!

Bush beans are an easy and enjoyable plant to grow in the home garden. These particular beans do not require a trellis and will be ready to start harvesting in about 50 days. Learn more about growing your own bush beans with UF IFAS Escambia County Extension In the Home Garden.
Loquat trees provide nice fall color with creamy yellow buds and white flowers on their long terminal panicles. These small (20 to 35 ft. tall) evergreen trees are native to China and first appeared in Southern landscapes in the late 19th Century. They are grown commercially in subtropical and Mediterranean areas of the world and small production acreage can be found in California. They are cold tolerant down to temperatures of 8 degrees Fahrenheit, but they will drop their flowers or fruit if temperatures dip below 27 degrees Fahrenheit.

Leaves – The leaf configuration on loquat trees is classified as whorled. The leaf shape is lanceolate and the color is dark green with a nice soft brown surface underneath. These features help give the trees their tropical appearance.
Flowers – 30 to 100 flowers can be present on each terminal panicle. Individual flowers are roughly half an inch in diameter and have white petals.
Fruit – What surprises most people is that loquats are more closely related to apples and peaches than any tropical fruit. Fruit are classified as pomes and appear in clusters ranging from 4 to 30 depending on variety and fruit size. They are rounded to ovate in shape and are usually between 1.5 and 3 inches in length. Fruit are light yellow to orange in color and contain one to many seeds.

Propagation – Loquat trees are easily propagated by seed, as you will notice as soon as your tree first bears fruit. Seedlings pop up throughout yards containing even just one loquat tree. It is important to note that the trees do not come true from seed and they go through a 6- to 8-year juvenile period before flowering and fruiting. Propagation by cuttings or air layering is more difficult but rewarding, because vegitatively-propagated trees bear fruit within two years of planting. Sometimes mature trees are top-worked (grafted at the terminal ends of branches) to produce a more desirable fruit cultivar.
Loquat trees are hardy, provide an aesthetic focal point to the landscape, and produce a tasty fruit. For more information on growing loquats and a comprehensive list of cultivars, please visit the UF EDIS Publication: Loquat Growing in the Florida Home Landscape.

Just before the recent cold weather I harvested seed pods from my roselle, Hibiscus sabdariffa, and made the most delicious and nutritious iced herbal tea.
You may have heard other names for this plant of Asian or African origin: bissap, red sorrel, Indian sorrel, Jamaica sorrel, Florida cranberry or jelly okra. Whatever name you call it, it has been grown in Florida since the late 1890’s.

People around the world enjoy consuming roselle in many ways. In addition to making a beverage from the fleshy fruit, it is used to make jams, jellies, relishes, syrup and added to salads. Harvest the fruit when it is large (as in the photo) but before it gets tough. Leaves can be eaten raw in salads or cooked into dishes. Even the seeds can be made into a high protein meal or ground into a coffee substitute.

My lone roselle plant provided hundreds of fruits and was so easy to grow. In the spring it started as a small 3-inch seedling and by November it grew to over 4 feet tall and wide. Roselle can grow 6 to 7 feet tall. It’s not too picky on soil type if it gets plenty of sun and consistent moisture. Few pests are attracted to roselle. However, deer will eat this down to the ground, as they will any hibiscus. Since my garden is plagued by hungry deer, I placed the roselle in the back of a landscape bed with a border of plants unappetizing to the deer. Expect roselle to start blooming in mid-summer and continue through frost. Blooms only last one day before forming the equally attractive fruit.

Roselle is a tropical plant and susceptible to frost in northwest Florida. To have seeds for next year, let some of the fruit stay on the branches to let the seed pods turn yellow/brown and ripen. There are also many online seed companies that carry seed.
