The biggest problem folks have with flowering potted plants in the heat of summer is remembering that they need water, lots of it. One way to work around having to remember to water every single day is to plant something that doesn’t like too much water but still can churn out a great daily flower show. For this job, there’s only one choice, Purslane (Portulaca oleracea).
Purslane is a super showy, low-growing, succulent-type annual that loves it hot and a little on the dry side. If planted in the ground, it will form a 6-8” tall flowering carpet over the surface of the soil, but I think it really shines when allowed to fill and then spill over the sides of a container! Individual purslane flowers close shop for the day in late afternoon, but cheerily pop back open as soon as day breaks the following day. For best results, make sure the container you plant in has ample drainage holes in the bottom and fill with a quality, quick-draining potting mix. After planting, top dress with a slow-release fertilizer according to the label rate and water only when the soil begins to dry out (every other day or so, generally). Plant a Purslane today!
It seems like every time I pick up a home and garden type magazine, the cover photo is dotted with flowering orchids and indoor foliage plants that are inevitably in pristine condition. However, years of experience troubleshooting issues with both my own interior plants and those for clients tell a different story. All too often, indoor potted plants languish for years, barely alive, until they finally succumb. I’ve taken several to the plant graveyard just past the edge of the back yard because of this exact scenario. In recent times though, I’ve figured out a way to mostly avoid pitiful looking indoor plants – take them outside in the warm months!
To appreciate the perks of getting your indoor plants outdoors, it’s helpful to first think about why most interior situations aren’t very conducive to plant growth. There are three primary reasons houseplants fail: not enough light, improper watering, and low humidity. Most plant species grown for interiorscapes hail from the tropics where they grow in the understory of large trees, receive bright, filtered sunlight, and experience abundant moisture and humidity. These conditions are VERY hard to mimic in the typical American house unless you huddle all your plants near windows, take steps to increase humidity (which doesn’t play super well with furniture and other household items), and really tune in your watering. Taking indoor plants outside to play in the Panhandle summers just really makes the whole situation much easier!

Now that you’ve made the decision to move your indoor plants out, figuring out where to site them is the next step. I’ve found that, with few exceptions, houseplants prefer to be in a bright area but away from direct sunlight – under mature trees, on a covered porch, anywhere that doesn’t get direct sunlight will do! It is also a great idea to place plants near a watering source. If a hose doesn’t easily reach the spot or it’s inconvenient to tote a watering can to them, your plants won’t get watered regularly and will suffer. You’ll be surprised how much water plants use when they’re in conditions conducive to growth so be sure to check pots every couple of days to prevent droughty conditions! Once in these new and improved growing conditions, your houseplants will also respond very well to a little extra fertilizer. A good general prescription is a topdressing of a slow-release fertilizer using the recommended label rate as soon as you bring them outside and following that up once each month with a supplemental liquid fertilizer.
Keeping houseplants happy in the Florida summer is easy and begins with getting them outside. Find a spot with bright, indirect light, keep them watered well, add a little fertilizer, and watch them grow like they never have before!

2022 has been a good tomato growing year for many Panhandle gardeners, myself included. It would have been difficult to have better climatic conditions to aid a terrific tomato harvest. After enduring a late frost just before Easter, the Panhandle then experienced two mild months in April and May that combined with nearly a month of dry weather during fruit development to deliver an excellent fruit set season with minimal disease and insect pressure. However, despite the favorable growing conditions, I have talked with several gardeners that once again struggled to yield a good crop of fresh garden tomatoes. Why is that? With the Panhandle tomato home gardening season nearing its conclusion, now is a perfect time to revisit 3 of the most common mistakes that prevent an excellent harvest!
Not Starting Early – Since Memorial Day, the rain and heat have really ramped up. These hot, wet conditions are perfect for developing tomato plant problems like fungal and bacterial diseases, not to mention the fact that tomato plants will stop setting fruit once nighttime temperatures rise above 75 F. While spraying fungicides preventatively can certainly help decrease disease incidence, the absolute best thing a gardener can do is try to get ahead of the disease-bringing heat and humidity by starting plants early when more favorable growing conditions prevail. So, what is early? I try to have tomato transplants in the ground by March 15 or soon after*. If you plan to grow plants from seed, they should be started indoors mid-January for planting outdoors in mid-March. Most tomato varieties take between 60 and 80 days to mature after planting, so a mid-March planting date normally yields harvestable tomatoes by the middle of May, comfortably beating the June disease deadline. *Planting early means protecting plants from occasional late frosts. Be prepared!
Not Scouting Your Plants – Pest and disease problems are a lot easier to manage if caught early and the best way to do that is to spend time with your plants. If you scout (just walking by and giving plants a short inspection) daily, you’ll learn what tomato plants and the beneficial insects that hang around all the time are supposed to look like an and be able to spot abnormalities and bad bugs when they occur. While tomato diseases and pest outbreaks can certainly cause a lot of damage in a short amount of time, they don’t reach disastrous levels immediately – be vigilant and catch them early!
Not Fertilizing and Watering Correctly – It takes a lot of energy for a tomato plant to grow a nice, bushy plant AND yield an abundance of America’s favorite vegetable (or fruit, depending on who you ask). To produce that necessary energy, gardeners must ensure plants receive adequate nutrition and water. Here’s my general prescription. At planting, apply a general purpose, slow-release fertilizer according to the label rate (for example, Osmocote, Harrell’s, or similar) and gypsum (a calcium supplement that helps prevent blossom end rot) at one pound per hundred square feet of garden. Then, supplement later in the season with a quick-release general purpose fertilizer sufficient to drive growth and fruit development. Watering is more of an ongoing concern. For the first couple of weeks of the tomato plant’s life, you can get by with watering once a day or every other day. As the plants get larger and the days get hotter however, watering twice daily is often needed to prevent wilting down in the heat of the day. Allowing tomato plants to wilt, even for a little while, is an excellent way to encourage blossom end rot and a subpar harvest!
When tomato season rolls around in 2023, remember to start early, scout often, and water and fertilize correctly. Follow those few tips and you’ll be well on your way to a great harvest in 2023!

I’m thinking of trying hydroponic gardening on a few tomato plants this year. Do you think a 50/50 mix of perlite and vermiculite would be a good approach for a soil medium? I’d like to use 5-gallon buckets and keep maintenance to a minimum.
At one time or another, we have all added rocks or broken pieces of clay pots to the bottom of a container to improve drainage. This practice can actually have the opposite effect, causing the potting soil to stay too moist. Since many container-grown plants like good drainage, we end up with plant issues.

Growing Key Limes in the home landscape is not only a fun and unique addition, but is also delicious – any way you slice them.
The key lime, Citrus aurantifolia, originated in southeast Asia. Genetically speaking, the key lime is likely a tri-hybrid cross between the “odd ball fruits”, known as citron, pummelo and a microcitrus species, Citrus micrantha. There is little commercial key lime production nowadays in Florida, but the fruit remains a very popular landscape option.
The key lime is a small, bushy tree that makes harvest and pruning a breeze. Like most citrus, it’s self-pollinating. The key lime is also an ever-bearing fruit, so there is no real seasonal harvest. The tree could technically bloom any month of the year. There are very few varieties, as trees mostly come from true seed or air layering.

Climate is an important factor when deciding to plant a key lime. They are sensitive to cold temperatures, especially below freezing. For the Panhandle, it’s wise to keep key lime trees as patio citrus. In other words, keep the trees in pots so that they can be moved indoors for protection during the winter months. In the ground, trees should be planted in an area where there is a significant wind block. Once a few years have passed and tree has become more mature and acclimated to the environment, they may be able to survive on their own, though it is recommended to cover the tree under sub-freezing temperatures. However, it is important to remember that sunlight is a catalyst for citrus fruit production, be sure to plant the tree in an area with full sun.
The usual suspects of citrus insect pests apply to the key lime also. Citrus leaf miner and mites are the most common culprits. Horticultural and insecticidal oils will certainly help to combat these threats. For planting, key lime is well adapted to a variety of soil conditions in Florida. Be sure to water newly planted trees every other day for the first week and then one to two times a week for the first couple of months. Water periodically after that, making sure the soil doesn’t stay completely dry for long periods. A 6-6-6 fertilizer works great for the key lime. Please follow the fertilizer schedule found in the UF/IFAS EDIS publication, “Citrus Culture in the Home Landscape” by Robert E. Rouse and Mongi Zekri: https://edis.ifas.ufl.edu/pdf/HS/HS132/HS132-11822781.pdf
A final interesting thing about the key lime is the ripening stages of the fruit. Because key limes are ever-bearers, blooms can develop at sometimes widely varying times. This causes an uneven development of fruit across the tree. Be sure to wait until the fruit turns begins to turn yellow before harvest. That’s when it’s mature to eat! Fruit can be stored for up to a week in the fridge or can be juiced and stored in the freezer for later use.
