In a world of limited time and space, container gardens seem to make more and more sense. Poor soil and no place to put plants in the ground are no longer good excuses for not being able to enjoy the simple pleasures of gardening. Container gardening allows the individual to create gardens to fit any situation. Gardening in containers can be just as rewarding as having a full-size garden.
There are a few items to consider when you are planning your container garden. The first is the plants you intend to use. If you are planting more than one plant in the same pot be sure that all your plants meet the same requirements. The requirements you should consider are amount of light, amount of water, climate and fertilizing needs. Some other things you might want to think about when planning your container garden are height, color, and texture. A nice variation of these elements will make your container gardens more attractive and increasingly more interesting to look at.
The next step in container gardening is choosing your container. A good rule of thumb is: “Anything that holds soil and has drainage holes in the bottom may be transformed into a container garden.” It can be a pot you purchased from the local gardening center or an old bathtub you picked up off the side of the road. However, be sure that the size of the container matches the current and potential size of your plant. For vibrant plant growth, the containers must provide adequate space for roots and soil media, allowing the plant to thrive.
Colorful containers bring life to your small spaces.
Next on your list is choosing a soil for your container. Container soils need have good aeration and decent drainage, while still being able to retain enough moisture and nutrients for plant growth. When choosing what to use in containers, never use garden soil by itself. When garden soil is added to a container, both drainage and aeration are severely impeded, and the results are plants that grow poorly or not at all.
Container soils are often referred to as soilless or artificial media, because they literally contain no soil. They are commonly composed of various media such as peat moss, perlite, vermiculite, bark and coir fiber (ground coconut hulls) in a variety of mixes. When using soilless media remember t0 moisten it slightly before planting. Fill a tub with the media, add water and lightly fluff the media to dampen it. This will keep the mixture from becoming hydrophobic (unable to take up water) throughout its life in the container. When adding media to your containers, never fill the pot to the top. You should leave about a one-inch space between the top of the soil and rim of the pot. This will make watering the pot easier as it provides a place to “put water” and not have it run over the edge.
When watering your container gardens, the best time to do so is in the morning. Watering in the morning allows the leaves of your plants and soil to dry out, preventing diseases and viruses. Remember that overwatering is the most common reason for fatalities in container gardens. Check your soil by pushing your finger into the media; if the media is moist don’t water it. When it comes to fertilizing your container gardens, fertilize only as needed. Over-fertilization will result in a buildup of salts and may burn the roots of your plants. Try to fertilize your plants during the growing season, and only if needed during the dormant seasons.
The most important objective when container gardening is to be creative. Maybe, try a variety of plants in one container garden. While an nicely put together individual container can be quite impressive, think what might happen if you put several containers together in a group. Also, don’t limit your container gardens to flowers–many vegetables can be grown in a container and actually do quite well. There really is no limit to what can be done in a container!

The most numerous animals on the planet are insects and although less than 1% cause damage to our landscapes, most are viewed as pests. Many insects perform clean up tasks that keep our environment from being littered with carcasses and trash while others actually attack and feed upon insects that are direct pests to plants.
It is important to recognize that all insects are not pests and take the time to get to know a few that might actually be performing a beneficial job in your landscape. Probably the most easily recognized beneficial bug family in Florida landscapes are the ladybird beetles (Coccinellidae). There are several species of ladybird beetles with different food preferences including mildews, mites, whiteflies, scale insects, and aphids.
Another group of insects that include some predatory species is the stink bugs. Some stink bugs do eat plants, but there are also many that are beneficial such as Florida predatory stink bug (Euthyrhynchus floridanus). The Florida predatory stink bug preys on velvetbean caterpillar, okra caterpillar, alfalfa weevil, and flatid planthopper. One of the distinguishable characteristics between plant feeding and insect feeding stinkbugs are the shape of their shoulders. Plant feeders have rounded shoulders and predatory have points on their shoulders.
The next time you are disturbed by a bug in your garden, take a moment to watch what it is eating and try to identify it before assuming it is a pest. After all, there are many beneficial bugs that help to balance out the “bad bugs.”

As we begin to approach our North Florida hot summer months, Gary Wade with the University of Georgia College of Agriculture and Environmental Sciences Cooperative Extension reminds us that, “temperatures in the high 90s and several weeks without rain can lead to serious, sometimes fatal, conditions for landscape (and garden) plants“. Most likely, we will also experience extreme temperatures in June and July. Under these conditions, heat stress is a great concern for both plants and people in the landscape or garden. Remaining hydrated is key to preventing heat stress.
For plants, mulching is an effective means to conserve moisture in the soil. It also cools the plant root zone, and helps to control weeds. Removing weeds that are growing around desirable plants will also help reduce soil moisture losses.
Consider watering your garden or landscape early in the morning. This method takes advantage of cooler morning temperatures, which can extend soil moisture conditions thus making soil moisture available during the hottest times of the day. Early morning watering will also discourage disease problems on plants susceptible to fungal growth such as lawns, roses, and cucurbits.
The best time to work in the garden or landscape is during the morning hours. To beat the heat, stay hydrated by drinking plenty of water. Heat stress disorders develop when the body cannot shed excess heat. Heat stress, heat exhaustion, and heat stroke are illnesses that can overcome you when your body is unable to cool itself.

The last week of April 2014 brought with it 10-22 inches of rain across the panhandle in a matter of days. Some areas had immediate flooding and standing water, while others may be in areas at risk of rising rivers and streams. As the water recedes, many people are wondering how all the water will affect their landscapes.
Only time will tell what the long term impact will be, but here are a few things to watch for and what you can do to try to moderate damage.
- Let soils dry out before driving vehicles or other equipment on grassy areas. Even if the water is not visible, if the soil is still saturated, driving lawn equipment or cars may cause ruts.
- Do not leave automatic irrigation systems running on established shrubs, trees, and lawns. If your system is set to run in the early morning hours, you may not think about it being on, check your systems and hold off on adding water until soils dry out and the plants need it.
- Watch for fungus symptoms and treat if needed. Wet plants and cool weather are ideal for some Brown Patch on lawns, be aware and monitor landscapes closely. If disease is suspected, contact your local county extension office for recommendation.
- When mowing, leave a longer leaf blade to compensate for root stress.
- Look at the base of trees and shrubs to make sure silt and sand have not buried the crown or root flare. Also look for erosion of root zone, these areas may need correction. “Salvaging Flood-Damaged Shrubs and Ornamentals.”
- Adjust fertilization as needed; if you recently applied fertilizer it has likely runoff or leached from the site. However, if you suspect fungal disease do not fertilize until disease is managed.
- Stress in turfgrass, for details read “Watch Turf for Flooding Stress”
- You may see new weeds (seeds or segments may have washed or blown into your yard)
- Tree and shrub decline or death read “We Had Plenty of Rain, Why are My Trees Dying?”
- Although this storm was not a hurricane, “Assessing Damage and Restoring Trees After a Hurricane” has helpful information for areas with wind damage
- Nutritional deficiency symptoms in palms may show up 4-5 months from now. “Nutrient Deficiencies of Landscape and Field-grown Palms in Florida.”
- Decreased availability and increased price of sod (flooded fields prevent harvest and increase inputs for disease, weed, and nutrition management)
- Scheduling changes or maintenance adjustments by landscape contractors. Turfgrass and ornamentals will likely need different maintenance applications than in years past to correct issues related to flooding and excess rain.

Now that spring has finally sprung and summer is well on its way, you may find yourself taking a stroll through your landscape and assessing damage done by late cold spells. However, it may not be a frost problem that has your plants looking worse for the wear. They could be experiencing nutritional imbalances which affect overall plant health. Most cases involving nutrition issues in plants can be linked back to the soil. Therefore, if you suspect a problem I suggest testing your soil to ascertain pH and nutrient levels. You can obtain a soil test kit at your local UF IFAS Extension office. Another way to diagnose your plant damage is to visually catalog its symptoms. Symptoms of mobile nutrients, such as nitrogen and phosphorus, tend to reveal themselves on older leaves first. Whereas, immobile nutrient symptoms (i.e. boron and calcium) will show up on newer leaves. These flow charts can help to narrow down which essential element may be lacking in your plant’s diet.

How can an animal that does such much to help rid your lawn of pests be so hated by most homeowners? Such is the life of the mole.
The beneficial mammal is a soil dweller that tunnels through the soil, increasing aeration as it searches out a meal of beetle grubs, mole crickets, and slugs. Moles prefer loose soil and can tunnel more than 15 feet an hour. Moist soil brings the food source closer to the surface which in turn bring moles up to expose raised tunnels to homeowners. These tunnels are mostly cosmetic and show up easily in mulched areas and lawns with heavier weed populations. Most homeowners with a healthy, thicker lawn will rarely notice mole activity unless they encounter loose areas as they walk over the turf. These can easily be pressed back down with your foot.

There are management techniques for moles which include traps and ridding the lawn of the food source. The best practices are to manage the turf through proper mowing, watering, and fertilizing to create a uniform, healthy cover. For the most part, mole management is not even required. Consider the benefits of the moles as predators and allow them to be a natural part of the landscape environment. For more information on moles read the University of Florida IFAS Extension publication.
