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!

Some of the many benefits of starting your own home garden are having fresher, more nutritious produce, the positive effects on physical and mental health, increased consumption of fresh fruits and vegetables and a potential cost savings. Also there are many advantages to starting a garden in the spring with transplants. You avoid bad weather, achieve earlier and higher yields, avoid insect and disease issues, and can choose the best and strongest plants to add to your garden.

Now is the time to start planting seeds indoors for warm season crops such as tomato, pepper, cucumber, eggplant, okra, summer squash, watermelon and many more. It is important to consider the number of days to harvest, planting zone, and location to plant. Buy seeds from a reputable source and check the expiration dates/sell-by dates and follow the packet.
For some vegetables, buy transplants from your local nursery. Photo by Molly Jameson.
When seeding the containers follow instructions for the seeding rates, spacing and depth on your seed packet. Smaller seeds can be broadcast over the surface and larger seeds will need to be covered with soil. Temperature and humidity are important for germination. Your packet will be specific on how deep to plant the seeds and a range of how long it will take to germinate. Label your container with the vegetable name and date seeded. You may find yourself like me and thinking you will remember what it is only to be guessing what you have as it germinates!
Most seeds started indoors will be ready for the garden in 4 to 6 weeks. Transplants must be hardened off first which means you should reduce the amount of water and stop fertilizing 1-2 weeks before they are ready to go into the garden. The seedlings will need a good bit of sun/light and moisture once they germinate to avoid leggy and stretchy plants.
The next step is to care for your transplants. As you have taken the time to seed them, watch them grow, and then put the plants into their new home it is important to set them up for success. Monitor the transplants for insect and disease on a weekly basis. Make sure the garden is free of weeds before the plants go into the ground. Weeds will fight for the same water and nutrients as the transplants. Transplant when the environmental conditions are best. This means to plant them in the morning, on a cloudy/overcast day, and when there is not a big storm in the forecast. When taking the little transplant out of the pot be careful to not disturb the roots and do not pack the soil around the roots.
If you have any questions on spring gardening please contact your local extension office for more information.

It is freezing cold this week and hard to believe that we are already talking about “What to Plant” and “What to Do” to get started early. In North Florida there are cool-season annuals that can be planted now. The list includes pansies, violas, petunias, and snapdragons. As we are coming to the end of January it is time to plant crinum, agapanthus and gloriosa lily bulbs. Make sure to mulch these areas after planting to protect them from the cold temperatures. This is also the month to plant camellias, which these come in many colors and forms that your local nurseries will carry this time of year. If you haven’t planted all your cool season crops there is still time to do that now such as broccoli, kale, carrots, and lettuce. Irish potatoes can be planted now as well.
Now you might be asking “What can I do?”. January is a great time to prune non-spring flowering shrubs and trees to improve their form. This is a good time to plant deciduous fruit trees, this will give their roots time to develop before the warmer spring temperatures. Since existing trees are dormant, it is a good time to prune and fertilize them. When the temperatures are near freezing many of the tender plants will need to be covered to minimize damage. It’s a good time to plant a tree. Hurricane-resistant trees include live oaks, bald cypress, cabbage palms, and southern magnolias. It’s time to remove those dead spent seed pods on your crape myrtles and removing any crossing branches and twiggy growth will improve the appearance and the form of the plant.

As we go into February it will soon be time to apply a preemergence weed killer to your lawns to prevent warm-season weeds. Temperatures must rise to 65°F for 4 to 5 consecutive days before you do a preemergence application and make sure you are not using a weed and feed fertilizer. Citrus and other fruit trees can be fertilized at this time. The amount and frequency will depend on the age and type of fruit tree you are growing. Avoid pruning Citrus until spring to avoid any injury since cold temperatures are still possible. It is time to prune those roses this month to remove damaged canes and improve the overall form. After the pruning is complete you can fertilize and apply a fresh layer of mulch. They should begin blooming within 8 to 9 weeks after being pruned.
Dianthus, pansies, violas, and dusty millers are annuals that can take a chill and should be planted in February. You can continue to plant crinum and agapanthus this month and add on amaryllis and rain lily bulbs as well. If it has been dry make sure to provide plenty of water for the bulbs to establish and continue to protect them from the cold by adding mulch. Trees and shrubs will begin to bloom this month including red maples and star magnolias. Continue planting potatoes throughout the month and towards the end of February warm-season crops like tomatoes and pepper can be planted but be prepared to protect them from any late frosts.
