One very popular herb for the backyard garden is the evergreen Rosemary, Rosmarinus officinalis which serves as an attractive landscape shrub in addition to its culinary uses. Rosemary grows best in full sun and well-drained soils. When planted in the ground, rosemary can grow 4-5 feet in height and spread. Plants do have beautiful bluish flowers that form in late winter and early spring, providing nectar for bees.
Rosemary is generally a pest free plant but some gardeners may find damage resulting from an insect pest. Rosemary is one of the hosts for the Southern purple mint moth, Pyrausta laticlavia which will lay eggs on several plants in the mint family. Caterpillars feed on leaves along the stems which become matted with silken threads and frass from the insects. As a result of the feeding, leaves are not useable and plants do not look attractive. Heavy populations will stress plants.
Since rosemary is often used to flavor many foods, many people do not want to use an insecticide on the plant. One least toxic option that can be used safely on edibles is Bacillus thuringiensis. The product is specific for caterpillar management and safe for predators that may help manage some caterpillars. Homeowners may also physically remove caterpillars or prune out damaged stems on larger plants.

I’ve considered the “let it be scenario” with the invasives until I participated in the naturalist course. The biggest whap on the head was the description of what is contained in an oak tree as compared to a tallow and how the oak supports so many natives. Nature is wonderful..we just need to stop “messing around”.

Hey Donna They could be. International law prohibits the discharge of any waste from ships in federal waters, and specific waste in international waters. Many vessels carry large tanks, as do smaller vessels and aircraft, which are pumped out. But there is less law enforcement on the high seas and partial discharges could occur. For our cases in estuaries this of course is illegal. All watercraft in state waters can not discharge but must "pump out" - and most do. However, law enforcement have found, and cited, watercraft within marinas that were illegally discharging - so, it does happen.
February 25, 2022
Thank you for clarifying this issue. I am wondering…how do cruise ships/boats dispose of human waste? Could they be contributing to this problem?

I've searched the Pensacola ordinances looking for an answer to my problem. I'm a tree hugging type, very into preserving our planet and trees; but, there's a heritage tree right on the fence line that's roots have utterly destroyed the foundation of our pool house. There's one crack the runs nearly the entire length that's displace the floor by a full 1/2 inch. We're in East Hill in an old home and it's clear the root damage began long ago. What are my best options to mitigating this growing, pun intended, damage to my home?

Case law is on the side of your neighbor. If any part of the tree is over his property, he can trim it. If you refer to this document, there is case law on a similar situation. This is a quote from the document. https://edis.ifas.ufl.edu/fe962 "What is the liability for over-hanging branches and encroaching roots? Branches and roots frequently extend across property lines. Whether a branch or root from a tree on an adjacent landowner's property is the responsibility of the landowner with the tree located on his or her property or the landowner of the property to which the branches overhang or roots encroach depends upon the branches or roots themselves. If the branches or roots are healthy, then the landowner with the tree located on his or her property is not liable for damage caused by the branches or roots. The adjoining landowner may, at his or her own expense, trim back the branches or roots as he or she desires up to the property line. If the branches are dead, however, then the landowner with the tree located on his or her property may be responsible and could be liable for damages caused by the branches (1 Fla. Jur 2d Adjoining Landowners section 8 [2014]).
October 15, 2020
Landlord.
October 14, 2020
You mention part of a tree crosses a property line AND effects his property he is entitled to trim it at his expense. What if it just crosses the property line but does NOT effect his property, can he unilaterally remove a large limb. Say one that hangs over his drive.

Hey, nice article. I liked your advice on keeping the parsley out of the sun more in summer.
September 12, 2020
Even though purple hyacinth bean is an edible plant in many parts of the world, it is mostly considered an ornamental in our area. One of the reasons is that raw beans are poisonous and must be properly cooked before eaten. Because of the toxicity of the beans, it is best to plant in the ornamental garden rather than the edible garden.

Hi Rick. I am curious about the life cycle of the common sand spur. I live on the beach and would like to be able to Identify these plants early on to manually remove them from our sandy lot before they set seed.

In case you are interested, a book on the cultivation of the fig tree in the Albatera field has been published, it is a publication that will help the farmer / technician in the management of the crop, which also contributes to deepening the knowledge of it, in aspects as morphology, pollination, caprification, irrigation, fertilization; with novel data on pests and crop damage not known so far, with updating historical data on pruning and other techniques, with more than 200 images, and that will be a useful tool for the technician, farmer, student or for anyone who Want to delve into himself. https://www.paraninfo.es/catalogo/9788494343032/el-cultivo-de-la-higuera-en-el-campo-de-albatera

Beth, I have encountered some of the downsides you mentioned with this fabric. If the torpedo grass rhizomes run above the fabric in the mulch, it is easy to remove them; however, when they get under it, the effort involved is ten times more. The fabric must be cut and folded out to get at them. When you want to plant something in a new spot, the fabric must be cut to gain access to the soil underneath. I can sometimes cut through it with a spade, but mostly have to get a cutting tool. If the fabric is supposed to reduce erosion, it only works if the flow of water is on top of it. Once it breaks through underneath the fabric, you find soft spots with a hole below. My gut feeling, and of course I could be wrong, is that these fabrics are used more to reduce erosion before plants cover the areas. I noticed our landscaper only used it in areas that weren't relatively flat. Not a horticultural reason to reduce weeds and they certainly make it more difficult later for the gardener.
August 12, 2016
One of the best pieces of landscaping advice you can offer. The worst possible use is under 'landscape' rocks. Two sinister plots to foil future attempts to garden in that spot. As for weeds? What do they care? Neither effort thwarts unwanted herbaceous plants from taking hold.

Great article Carrie. Thank you. This is related to your first paragraph. After the "hurricanes" and so many homeowners, including Master Gardeners, were rushing to get all the pine trees left in the ground, removed, Dr. Thetford made a simple comment that I thought was so appropriate. Some had been talking about all the lightning and wind and they were having those darn pine trees removed. He said, "And now what will be the tallest thing in your yard?" Food for thought! Thanks again Carrie. Sonya Robinson .

Hi Deborah I believe I responded to you directly but wanted to add to the blog to make sure others saw the answer. One variety of vitex is listed in Florida as "Invasive, not Recommended". This is beach vitex, Vitex rotundifolia. Used in landscaping in coastal areas can lead to an invasive situation and is very difficult to remove once it begins to spread. We would recommend using a local native plant instead.
February 23, 2016
Vitex tree is different than Beach Vitex. Beach vitex was discussed in the blog post. The vitex tree is also invasive.
February 23, 2016
Is the Vitex tree invasive? I saw a Vitex shrub in Lowe's last year and was going to buy it. I looked for it a few weeks ago and they did not have any. I read that it was a fast growing shrub/tree that I wanted to plant along my driveway. Any info is greatly appreciated.
February 23, 2016
I did not know that Vitex is an invasive species. Does that mean all strains of Vitex? I saw some Vitex (not sure if Chinese) in Lowe's last year and was going to buy them, but I did not. I looked for them at Lowe's last week and they did not have any.
February 1, 2016
They do sell lawn herbicides in garden centers that contain the combination of 2,4-D and Dicamba, which are the active ingredients in Weedmaster. You may also find some products claiming brush control on the label with the triclopyr, that is the active ingredient in Remedy that provided better control of this weed. The brand names of garden center products vary considerably, but the active ingredients are similar, but may not be as concentrated.
January 29, 2016
I am having issues with this weed in my yard and wondering where I can purchase for residential use.
January 26, 2016
YES! Thank you - made the change. You read over and over looking for typo's etc. Do not pay attention to whether the direction was correct or not. Will double check on future post. Thank you for catching.

Better to have suggested keeping cats and other small pets indoors at all times, rather than just at night ; cats, both domestic and feral, especially wreak havoc on our ecosystems.
August 26, 2015
Dear Beth, Your articles are always inspiring. This one has a little different slant on the pest as we normally think about. This is a wonderfully surprising article in a very small amount of space. I believe that those that are not Master Gardeners will also be amazed. Would you give me permission to include this article in the next FFGC District 1 Newsletter? You will get all the credit of course. If it is not alright, I'll understand. Thank you, Sonya
August 26, 2015
Cats should not be let to roam outside at anytime, anywhere. There are many ways for them to be injured or killed. But most importantly is the wildlife they kill, the numbers of small wildlife killed by free roaming cats is huge and should not be acceptable. This slaughter of wildlife can be prevented by keeping cats indoors at all times. If a person cannot accept this than they should choose not to have cats. Please visit American Bird Conservancy (ABC) 'Cats Indoors' initiative. The death toll on wildlife, the potential for disease transmissions from cats to humans, and the possibility of injury or death to the cat should make all cat keepers think twice before they open the door and let kitty out unattended. Please help educate people on this subject. We can all easily help wildlife by keeping our cats indoors, safe and healthy. A cat can be happy and have a good life in the house.

Stephanie~ I have had my large rosemary for at least 15 years and, like yours, it blooms sporadically. I'm thinking it blooms better with enough water to drain. They are drought tolerant certainly, but aren't completely a desert variety plant... no water. Since they bloom in the drier part of Florida during the winter, some irrigation is good. Hopes this works for you.

Hey Kathy Chipmunks have never been in high numbers here in Florida. The few I have seen have been in the northern portions of counties that border Alabama and Georgia. Currently the population of those have been declining and FWC has now listed them. I do not think the squirrels are the reason for their low numbers. They are more common in rocky terrain and in colder climates where squirrels are still common. I think it is more of a climate issue. I am not sure why the few we have in the state are declining.
April 19, 2015
Do they taste like cherries in jams? Where is the best place to purchase these bushes if you wanted a decent quantity? What time of yr do they produce? thank you

curiously, I have noticed that there are no chipmunks in my area - NW Florida - specifically, Gulf Breeze. Is there a logical reason for this - we have squirrels but I have never seen a chipmunk and I would think the weather would be quite perfect for these little creatures.

Thank you! I hope your mailing list is very long and also that this paper will appear elsewhere. I am a volunteer in a visitors' center at the Gulf Islands National Seahore, and I hear frequetly from visitors how beautiful this area is. Part of that beauty is because there is plenty of it---and our visitors have said they appreciate that we are less "developed." I was young and adventurous 'way back when there were 10 animal phyla and ecological studies were simply "conservation" (so you see, my 1957 BS in Biology is quite outdated). I was worried back then and are even more so now, but with people like you and a steady drumbeat of your messages, perhaps the majority of us will enjoy a more natural, balanced way of iving after all.

Larry, from everything I've read, just pull several inches of the rhizomes up with the fern and place them in a natural crook or deeper bark ridges of the new oak tree, and they should do great. I've even heard of teachers keeping them alive in classrooms with spray water bottles in a bowl. Resurrection ferns are so hardy that I believe it'd be hard to go wrong. On a side note, we recently just picked up some firewood that had pieces of resurrection fern growing in loose bark--you could always take a small piece of bark that already includes some fern and place it on a horizontal limb to help transplant it. Let me know if it works for you!

Today, I went to the beachfront with my children. I found a sea shell and gave it to my 4 year old daughter and said "You can hear the ocean if you put this to your ear."

What I do in the garden is use very forceful streams of water to wash them off. This process needs to be repeated several times until their life cycle is disrupted. The undersides of the leaves must be washed as well. This works in the garden, but is labor intensive and would not be practical for large scale production. See the publication below for more info. http://nwdistrict.ifas.ufl.edu/hort/2012/05/10/as-summer-approaches-spider-mites-attack-ornamental-shrubs/

Jane, Asclepias seeds germinate in 3-4 weeks at temperatures of 68-86 degrees F. Seeds are short lived so plant soon after ripening. Milkweed are warm season plants so wait until after our last frost to set out the transplants, about mid to late March. If we get a late cold, be prepared to cover.
February 5, 2014
Our Garden Club in Panama City Beach is getting ready to co-op with our Conservation Park to create a Butterfly Garden.

Update 9/22/2031 The Blackwater River State Forest Trip Oct 3 is now open for registration. There's was registration delay due to our attempt to reschedule the Apalachicola trip originally scheduled for September 24. The date conflicts with an important meeting our Sea Grant Agents are required to attend. This meeting was not on the calendar when the original POL 2013 dates were announced. At this time, we cannot find a date that works for the trip leaders. Typically we open the trips for registration after the preceding trip is complete. So at this time we are opening the next trip to Blackwater River State Forest. To register visit http://panhandleoutdoorslive2013.eventbrite.com
