As the weather warms and we approach the last expected frost date, it’s time to start planning our warm season annuals.
Annuals are plants that complete their life cycle in one season. In North Florida, we recognize two annual color seasons: Winter annuals (cool season) and Summer annuals (warm season).
Warm season annuals generally cannot tolerate freezing temperatures and perform best during the long, hot days of spring and summer. In our climate we have many choices for our warm season or summer color beds.
It is an extremely important part of the planning process to determine if the site is shaded, part sun, or full sun. If it is part sun, note whether plants will receive direct sunlight in the morning or afternoon and how many hours of sunlight are expected. Check water sources for the site. Different plants have different water needs, so you would not want to install plants with high water needs in a site with no irrigation or limited access to water.
Another factor to consider in coastal areas is the possibility of salt spray or introduction through water sources. Some plants can tolerate salt and others are very sensitive. If it is likely that plants may be exposed to salt, choose plants with a medium to high salt tolerance level.
After you have assessed your site and determined what conditions will affect your plants, start with your plant selection.
Remember to group plants with similar needs together so that maintenance will be simpler and your plants will have the greatest opportunity to perform at their best. Most annuals will have some fertilizer needs due to their short life cycle. Be sure to amend the soil and provide slow release fertilizer throughout the growing season at the rate needed by your chosen plants. Do not apply fertilizer to plants that are suffering from drought stress, insect infestation, or disease infection.
When selecting plants from a garden center, look for healthy plants with well-developed root systems. If you pull the plant out of the pot you should be able to see bright white roots that are holding the soil together to the shape of the pot. If the root ball falls apart,the plant is not fully rooted and may struggle to get established. Look for disease, weed, and insect free plants so that you do not introduce a problem into your landscape.

I noticed aphids on my lettuce and planned to take them in to show some students. On the planned date I found they they had been consumed by parasitic wasps. I felt it was a sign of a balanced ecosystem.

Where can I find seed potatoes (red)? I am in Gulf Breeze.

I was actually wondering about the issue with the mower blades. I am constantly getting the ends of the grass cut on a way that has the tip of it drying out. Is the fact that the blades are a little worn, that is causing this issue of the grass getting dry at the top.

For sure on the Aucuba! I love it and use it throughout my front yard along with the cast iron plants. One of my favorite shade plants however is the Apostle's Iris, 'Neomarica gracilis'. They have survived the coldest winters so far and have come back beautifully. Thanks for the article. I have 2 shady beds I am renovating right now so I look forward to finding the Japanese Plum Yew and the Mahonia!

An evergreen shrub that does well in the shade for me is Aucuba japonica 'Serratifolia' An all green aucuba.

Nice article Julie. Just a side note that occurred to me as I looked at the pictures. Please don't recommend (I know you didn't in this article) that people plant close to the flare roots of a tree. The first radial distance of 3x the DBH of the tree is very, very important root area and what the arborist needs access to for many treatments. As important, perhaps more important is: 1. the tree trunk and exposed flare roots need to be dry when it is not raining and having vegetation in close proximity eliminates the breeze and keeps the tree trunk damp creating a decay/fungi opportunity; 2. cast iron plant, Jasmine, fern, etc. are major competitors in that critical root area. If a tree is stressed one of the cultural remedies is to clear out plants in that critical root area and install organic mulch, preferably pine straw. Keep up the good work!!

Hi Stan, I don't know how frequently that is done, however, if the gardener plans to change out the plants after a very short period of time they may leave them in containers. Some commercial properties may do that if they plan to swap out if anything declines (theme parks, other high profile spots), but most plants should not stay in original containers indefinitely. Eventually the plant's root system will outgrow the pot and will be unable to take up enough water to sustain itself. Julie

Miss McConnell, Is it a common practice by some homeowners to leave the annuals in their pots when they plant them in the Spring? Thank you

Hi David, The palm you are describing is likely Butia capitata also known as Jelly Palm or Pindo Palm. The fronds have a bit of a blueish or silvery color to them that makes them fairly distinctive. More can be found about this palm at the following link http://edis.ifas.ufl.edu/pdffiles/ST/ST10500.pdf. If you like, send a picture to my email and I can confirm if that's what you have. Have a great day! Julie juliebmcconnell@ufl.edu

We have a palm, locally known as a Jelly Palm" It's a very slow growing, like 12 feet in 15 years, and very bushy compared to the typical King palm. It puts out small groups of flowers, inside a hard, 3-4 ft. long woodlike, split, shell, which, of course become seeds. That is apparently what some old timers used for "Jelly:". Jelly Palm is not likely it's correct name. From that vague description, can you tell me what it is, or if not, what I can provide to help properly name it.

Please give me a call. I would like to discuss how Farm Credit can be involved in this program. My number is 850-718-5511. Thanks, Lesia Andrews

Hi John, Butterflies are rather specific about where they lay eggs and which plants their larvae (caterpillars) will feed on. For the Gulf Fritillary, the passionflower vine is the preferred larval host. I would not expect having this plant in your garden would have any direct effect on the number of caterpillars that would target tomatoes and peppers. If you would like to learn more about pests that are more specific to tomatoes and peppers, please see the following publication at http://edis.ifas.ufl.edu/pdffiles/IN/IN16900.pdf "Insect Management for Tomatoes, Peppers, and Eggplant"

if I plant this purple passionflower....will caterpillars start eating my tomatoes and green bell peppers. Thanks John Nelson

Hi Suzy, The link should take you to a leaflet publication by USDA Forest Service titled "Walnut Caterpillar." I checked the link embedded in the article and it is working tonight, but sometimes there can be other issues. I am adding the link below in plain text so that you can try to copy and paste into your internet browser. If you are still unable to access it I would be happy to scan it and send it to you directly as a .pdf in an email next week. Julie http://www.na.fs.fed.us/spfo/pubs/fidls/walnutcat/walnutfidl.htm

It would be great if you would submit this article for newspaper publication, especially Tallahassee Democrat. There are so many people that are misinformed about lichens and Spanish moss. Donna Legare Native Nurseries

Enjoyed your article. Wish I had time to plant winter annuals.

Noticed one of our longleaf pine saplings, in the middle stage has died out on the top 3" of the bud. The trunk and several lower limbs still have healhty green looking growth buds. We are located 3 blocks north of the Gulf of Mexico in Franklin County Fla. elevation +27' sandy soil. Approximately 25 trees are @200yr old, some cat faced. Another 50 trees are post turpentine era, and another 75 are in the grass and middle stages. We eliminated all the loblolly pine 10yrs ago in hopes of restoring the longleaf presence on our 4+acres.

What type of grass do you have? If you have centipede, you will not need any additional fertilizer for the season. How much did you put out in August/
September 10, 2013
Applied fertilizer to grass early August as I was away for 5-6 months. Can I apply again on 9/15?
