I live in the woods, so I mainly have a “natural” landscape. I remove trees, shrubs, and weeds as I see fit, but for the most part things just grow wild. However, there are a few spots in the yard where the previous owners did a little landscaping. Unfortunately, these spots have become a bit overgrown. One spot in particular features some gardenia plants around the HVAC units. At first, I was a little hesitant to prune these shrubs because they provide some shade to the units. However, they have become overgrown and I know they will grow back. I was patient to wait for them to finish flowering.

As you can see in the photo above, this gardenia has become a bit leggy. It is important to also note the good amount of branching and new growth at the base of the plant. There are a few pruning options available for shaping shrubs such as hedging/terminal pruning, selective pruning, and renewal pruning. While a tree form gardenia can be attractive, it wasn’t desired in this situation. This particular case called for renewal pruning to improve the form of the plant. Renewal pruning is probably the easiest type of pruning, because it requires the least amount of thinking. It basically involves removing the majority of old growth.

The picture above is of the same shrub that has been pruned heavily. Not only have the older, leggy branches been removed, but some of the newer growth has been removed to allow for better air circulation within the shrub. This will help reduce the incidence of disease.

Six weeks after being pruned, this shrub is flowering for a second time. In a matter of short time it will be providing much needed shade for the HVAC units again. (That is..if I remember to selectively prune throughout the year.) For more information on how to prune and what to prune, please visit the UF/IFAS Gardening Solutions page on pruning.

A common diagnostic service offered at your local UF/IFAS Extension office is plant identification. Whether you need a persistent weed identified so you can implement a management program or you need to identify an ornamental plant and get care recommendations, we can help!
In the past, we were reliant on people to bring a sample to the office or schedule a site visit, neither of which is very practical in today’s busy world. With the recent widespread availability of digital photography, even the least technology savvy person can usually email photos themselves or they have a friend or family member who can assist.
If you need to send pictures to a volunteer or extension agent it’s important that you are able to capture the features that are key to proper identification. Here are some guidelines you can use to ensure you gather the information we need to help you.
Entire plant – seeing the size, shape, and growth habit (upright, trailing, vining, etc.) is a great place to begin. This will help us eliminate whole categories of plants and know where to start.
Stems/trunks – to many observers stems all look the same, but to someone familiar with plant anatomy telltale features such as raised lenticels, thorns, wings, or exfoliating bark can be very useful. Even if it doesn’t look unique to you, please be sure to send a picture of stems and the trunk.
Leaves – leaf color, size and shape is important, but also how the leaves are attached to the stem is a critical identification feature. There are many plants that have ½ inch long dark green leaves, but the way they are arranged, leaf margin (edges), and vein patterns are all used to confirm identification. Take several leaf photos including at least one with some type of item for scale such as a small ruler or a common object like a coin or ballpoint pen; this helps us determine size. Take a picture that shows how leaves are attached to stems – being able to see if leaves are in pairs, staggered, or whorled around a stem is also important. Flip the leaf over and take a picture of the underside, some plants have distinctive veins or hairs on the bottom surface that may not be visible in a picture taken from above.
Flowers – if flowers are present, include overall picture so the viewer can see where it is located within the plant canopy along with a picture close enough to show structure.
Fruit – fruit are also good identification pictures and these should accompany something for scale to help estimate size.
Any additional information you are able to provide can help – if the plant is not flowering but you remember that it has white, fragrant flowers in June, make sure to include that in your description.
Learning what plants you have in your landscape will help you use your time and resources more efficiently in caring for you yard. Contact your local UF/IFAS Extension office to find out who to send requests for plant id.
