If you’ve been gardening for more than a few years, you may be confused by UF/IFAS recommendations that conflict with practices you’ve used for years. You aren’t imagining things, we do change recommendations based on the most current research available to help you with your agricultural endeavors.
I want to share a few common mistakes that gardeners make based on old recommendations but that research has shown are not the best choices. Check out the list below to see if you can break an old habit or two!
| Old Habit |
Current Recommendation |
| Throw a little “starter fertilizer” in the hole (or under new sod, seed, etc.) |
It is not beneficial to add fertilizer to plantinghole or under newly installed sod.Quick release (soluble) fertilizer may burn roots if added to planting hole.If applied properly, a slow release fertilizer may be applied to trees and shrubs but should be applied to the top of root ball or mulch following label instructions.Turfgrass grown from seed, sprig, or sod does not use fertilizer efficiently at planting. Wait 30 days to apply fertilizer – after roots have been established. |
| Dig the hole twice as deep and wide as the root ball for trees and shrubs |
1.5 times the width of the root ball is good, but planting too deep can be a death sentence.Planting depth should be 10% shallower than the distance from the topmost root to the base of the root ball. |
| Mulch 3-5 inches deep |
2-3 inches with a very thin layer directly over the rootball (less than 1 inch) and none touching trunk. This is the ideal amount to conserve water and suppress weeds. |
| Native and drought tolerant plants don’t need water |
All plants need water until established – depending on the type and size of the plant, weather, and soil conditions this may take months.Always plan to give a little TLC to newly installed plants no matter how tough they are supposed to be. |

I think it’s safe to say fall is officially here. Shouts can be heard from local football stadiums, occasionally a crisp fall breeze will send us looking for a light jacket, and coffee shops are pushing all things pumpkin. Now that we can officially appreciate the cooler fall weather, it may be time to stretch our legs and marvel at the spectacular show of color our landscapes are putting on. Here are a few plants that are showing off this time of year.
Firebush (Hamelia patens) – This charming Florida native will delight everyone with beautiful orange-red flowers throughout most of the year. Hummingbirds and butterflies enjoy the nectar in the flowers. Firebush can reach a height and width of 8 to 12 feet. It is a fast growing plant that will grow well in part to full sun environments.

Salvia (Salvia spp.) – Salvias are great plants for bringing butterflies and hummingbirds to your garden and as a bonus, they have no serious pests. With hundreds of annual and perennial species coming in an array of colors and sizes, you can easily find one or more to complement your landscape. Salvias perform best in full sun environments and are considered drought tolerant.

Turk’s Cap (Malvaviscus arboreus) – Turk’s cap can add a cheerful pop of color at a time when little else is blooming. This old-fashioned Florida-Friendly shrub like perennial is related to the hibiscus. It’s known for its bright red flowers that always seem ready to open, but never do. Turk’s cap starts blooming in summer and keeps going until through winter, unless hit by a hard frost. It can grow in full sun and reach up to ten feet tall and ten feet wide, so give it room to grow. This easy-care native perennial requires little maintenance once it’s established.

Coleus (Solenostemon scutellarioides) – When imagining fall color we often don’t consider coleus. However, the vibrant foliage can add interest to any landscape throughout the fall. Coleus is prized for its colorful foliage, which comes in shades of green, yellow, pink, red, and maroon. Coleus varieties can range from one to several feet in height. They can be used in hanging baskets, containers on patios, or in landscape beds. Coleus prefers partial shade and you can pinch the growing stems of young plants frequently to encourage dense foliage. Keep an eye out for mealybugs on coleus and use insecticidal soap if problems develop

Summertime is vacation time for people, not plants! While getting ready for that long awaited trip, it’s easy to forget about your lawn, landscape, vegetable garden and house plants. A little time spent preparing your leafy friends for your absence could save you needless worry and hours of extra work when you get back.

A vacation may be relaxing and rejuvenating for you and your family, but it can be hazardous, even deadly, for your plants. Unless you make adequate preparations before leaving, you could return to vegetable disaster.
One of the first things you might do before leaving home is ask a neighbor to check your plants periodically while you’re gone. All plants need some care. During an extended vacation container grown plants require special attention and different species have different needs. Be sure you give your friend specific instructions for the care of each type.
If you can’t find someone to personally look after your plants while you’re away, there’s plenty you can do prior to departure to make sure you don’t come home to a limp landscape and sickly house plants. Outdoor container plants should be placed in a shady area to conserve moisture. Under a tree or on the north side of a building are good locations. A thick layer of mulch will help conserve moisture for landscape plantings. Mow your lawn just before leaving, cutting the grass a little closer than usual. An unkept lawn can encourage disease, and it’s a tell-tale sign that no one’s home.
Give lawn and landscape plants a heavy watering – especially recently planted beds, which will need extra moisture. Also, thoroughly spray or dust your plants to protect them from insects and diseases while you’re away. If you have flowering annuals, cut the blossoms before departing. If you don’t, they’ll soon stop blooming. Harvest all ripe or nearly ripe fruits and vegetables. Like flowers, they will continue to produce only if they’re picked frequently. Otherwise, they’ll go to seed.
Do a thorough job of weeding. If weeds are allowed to go to seed while you’re away, you can expect to encounter much more difficult problems later in the season – even next year – when the seeds sprout. Weeding eliminates a major source of competition for your landscape plants’ food and water which may be in short supply during your absence.
Plants kept indoors require special consideration. Before leaving home, place your house plants in a room which receives indirect sunlight. Direct exposure to the sun will dry the soil too quickly. Of course, you don’t want to put your plants in a room that’s too dark, either. Too little light will almost always result in leaf drop. And, just before you depart, be sure to water your house plants thoroughly. This is especially vital, because – unlike lawn grass and landscape ornamentals – house plants cannot benefit from any rain that may fall while you’re gone.
You’ll enjoy your vacation more by making sure your plants are well prepared for your absence.

Homeowner accounts of white fluffy woolly masses on woody ornamentals have been on the rise. They can appear on the ends of a wide variety of woody ornamental branches in the landscape. A closer inspection of these white woolly masses can provide the curious observer with a startling surprise. “It’s Alive!” It moves and seems to jump at you, most likely jumping away from you. Once you have recovered from the mildly frightful encounter, you ask yourself, “What was that?”

They are planthoppers (Metcalfa pruinosa), an insect in the order Hemiptera. The common name for this woolly looking planthopper is the citrus flatid planthopper (CFP). As the name implies, they occur on citrus but can also be found on many woody ornamentals and fruit trees. The adult planthopper wing arrangement is tent-like, meaning that the forewings are held over the insect abdomen in a tent configuration.

The nymph, young immature insect, produces the white woolly material that is characteristic of CFP. At first sight, they can be mistaken for mealy bugs, which may look similar since they are covered with cottony white filaments. They can also be mistaken for cottony cushion scale.

In both of these cases of mistaken identities, the insect will not jump or hop around. No chemical control is necessary although sooty mold can occur on heavily populated plants. In that case, a soapy water treatment can be applied.
