Many shrubs can benefit from a little pruning. Choosing what to prune to maintain a plant’s natural look can sometimes be a challenge. Get a few tips on pruning shrubs with cane type growth from UF IFAS Extension Escambia County.

A beautiful plant with a confusing parentage

A beautiful plant with a confusing parentage

Plant names in today’s industry are not as simple as the established binomial (genus and specific) and a common name. Many of the plants that you get for your landscape are varieties, cultivars, and hybrids. To make matters more complicated, there are trade names that are given to plants to aid in marketing.  We see the Endless Summer® hydrangea or Purple Pixie® Loropetalum.  Throw into the mix the work of plant taxonomists who are always reclassifying plants and we can all be truly confused about a plant’s name. 

Even as names change, it is still fun to learn plant names.  Just recently, I sent plant pictures to the UF Herbarium to help get a clarification on the plant I was calling Georgia savory, Clinopodium sp.  This is one of my favorite plants because it makes a spreading groundcover that grows about 1.5 feet tall and has tubular flowers in spring and fall. Many pollinators visit the flowers.  It also grows well in sandy, well drained soil and thrives on occasional water.  I have a single plant in my backyard that only gets water from rain and has grown to five feet wide over several years.  It is definitely a low maintenance beauty.

My results back from the UF Herbarium did not completely clear up this plant’s name. There are reports that it is a hybrid of Clinopodium georgianum ×  Clinopodium ashei ‘Desi Arnaz’. Other information suggests that it is an intergeneric hybrid between Clinopodium and Conradina named x Clinadina ‘Desi Arnaz’.

The lesson from all this confusion is to just do your best. Realize that all of us can be mistaken on a plant’s name and even those that study plants in depth don’t always agree on a name.  In the world of plant names, change can happen.

Although a beautiful flowering vine in the late summer and early fall, the non native Autumn clematis can take over an area and escape to natural areas. Learn how to distinguish this plant from the native clematis.

When It’s Too Hot to Garden.  What to Do?

When It’s Too Hot to Garden.  What to Do?

I don’t know if you’ve noticed, but it’s been hot outside.  Like really, scorching, hellacious, dog days hot.  In this weather pattern we’ve been in, it’s hard to make yourself do non-essential stuff outside that doesn’t involve swimming and so our gardens go by the wayside.  In my opinion, that’s totally okay!  Give yourself a rest from the garden and landscape chores for the next couple of weeks and get your fall gameplan ready.  The following are some things to think about over the next few weeks to prepare yourself for the coming cooler weather!

Get your soil tested.  If you’re an in-ground vegetable gardener or just like to have an attractive lawn/landscape, performing a simple soil test can offer either peace of mind that your soil’s pH and fertility is good or give you a nudge to schedule some needed amendments.  Though I don’t recommend fertilizing lawn grass this late and there’s no need to fertilize the garden before it gets planted in mid-late September, you can certainly begin to source and price fertilizer for the appropriate time based on your test results.  However, now IS the perfect time to get lime out in a vegetable garden if your pH has sunk beneath the recommended 6.5.  Lime takes weeks to months to begin to alter soil chemistry so the sooner the better if it is needed! 

Order seeds.  While I love to support local farm stores and plant nurseries, you are limited with the vegetable and flower varieties you can plant by what they have in stock.  I enjoy trying new/improved and heirloom plant varieties each year and, most of the time, these can only be found by ordering online.  For the latest in vegetable and cut flower varieties with a nice mix of heirloom cultivars thrown in also, I can recommend Johnny’s Selected Seeds, Baker Creek Heirloom Seeds, Seed Savers Exchange, and other similar purveyors – all of these are great places to look.  Continue to purchase your more common standbys through local outlets but, this year get different and try new things by ordering online!

Develop a garden/landscape plan.  I doubt there’s a gardener amongst us who wouldn’t like to rearrange things a bit outside.  Maybe you planted your lettuce a little too closely together last year, you’ve been dreaming of installing a new flower bed, or you really want to do a full garden/landscape renovation.  The best way to be successful at any of these things is to get outside (or at least look out from behind a window in the A/C), take stock of what is already there, the space that is or might be available, research what plants or varieties might do well in your yard/garden (your local UF/IFAS Extension office is a great resource for this), and begin to sketch your ideas out.  This planning step WILL save you time and money by ensuring you don’t purchase too many plants, by picking plants that will do well, and ensuring you install everything at the correct time.

So, take advantage of the heat, stay inside, and work up your garden gameplan together this August – fall is just around the corner.  For help with soil testing, recommendations on plant varieties to purchase, or working up a garden/landscape plan tailored to you, contact your local UF/IFAS County Extension Office.  Stay cool and happy gardening!

Mole Crickets

Mole Crickets

A mole cricket has a face only a mother could love. They are so strange looking, in fact, that in the past week I’ve had two people ask me what they were. They have large, round, helmet-like heads, undersized eyes, and massive front claws used for digging. Unlike your garden-variety crickets, which really don’t cause any major damage to home landscapes, the mole cricket is quite the turfgrass menace. Instead of hopping about aboveground, they tunnel beneath the lawn and feast on the roots and leaves of grass, often destroying entire yards. They are also vegetable pests, going after tomatoes, cabbage, and peppers.

Mole crickets spend most of their time below ground and form burrows for hiding, laying eggs, and traversing through their territory. In mating season, males create a monotone song that averages 88 decibels—as loud as a motorcycle! The call comes from their burrows, which have funnel-like openings that expand at the surface, creating amplification comparable to a horn.

The tawny mole cricket (Neoscapteriscus vicinus) is the most common to our area and is an invasive species from South America. UF IFAS has had a specific research program related to mole cricket management since the late 1970’s. One successful outcome of this program has been the introduction of a biological control species, the larra wasp (Larra bicolor). The wasp manages mole cricket populations by stinging and temporarily paralyzing crickets. A female will then deposit an egg into the mole cricket’s body. The cricket recovers and goes about its daily routine until the egg hatches, at which point the larval wasp feeds on and eventually kills the mole cricket. Along with the wasp and release of flies and a nematode that also manage mole crickets, the biocontrol methods introduced between the 1980’s and 2004 have resulted in a 95% reduction in mole cricket populations in north Florida.

If you are seeing mole crickets, you can attract larra wasps to your property by planting shrubby false buttonweed or partridge pea plants, which the wasps feed on. If you have serious damage from mole crickets, check out this thorough Mole Cricket Integrated Pest Management Guide, or contact the horticulture agent at your local county extension office to get a site-specific recommendation for management.

Centipedegrass is a low maintenance turfgrass for North Florida landscapes. Scientists from Georgia also found an added benefit when the grass is in flower. Learn about the specific insects found visiting the flowers of centipedegrass.
