The Grass is Getting “Hungry”

The Grass is Getting “Hungry”

Northwest Florida’s weather patterns can present challenges to maintaining a health lawn. Heavy rains promote fast growth and relentless sunshine causes lawns to fade.  In the last 200 days we have received at least 68 days of rain.  While the rest of Florida was experiencing record drought, the Panhandle was experiencing torrential downpours.  With every drop of rain your spring fertilizer is being metabolized by the lawn, reducing how many nutrients remain in the soil.  Even the best slow-release fertilizer will only last 3-4 months.  The message is: “It’s time for more fertilizer.”

A healthy lawn is an important component of the urban landscape. Not only do lawns increase the value of a property, they also reduce soil erosion, filter stormwater runoff, cool the air, and reduce glare and noise.  A healthy lawn effectively filters and traps sediment and pollutants that could otherwise contaminate surface waters and groundwater.  Lawns require nutrients throughout the growing season to stay healthy.  In Northwest Florida the growing season is typically April to October.

Proper fertilization consists of selecting the right type of fertilizer and applying it at the right time and in the right amount for maximum plant uptake. The type of fertilizer should be based on a soil test, available through UF/IFAS Extension. The timing of application and amount of fertilizer is dependent on the research-based recommendations for the grass species and the fertilizer analysis of the product being used.

Select only a fertilizer that states that the product is for use on residential turf. Do not use a fertilizer meant for flower or vegetable gardens on lawns. By Florida Administrative Code, Rule 5E-1.003, the Urban Turf Rule requires that the fertilizers being applied to residential lawns are labeled for the site and the application rates be followed.  Typically, these products will contain both slow-release nitrogen and low or no phosphorus.  Slow-release nitrogen will provide a longer-lasting response from the grass and reduces the potential for burning. For more information on the Urban Turf Rule go to: http://www.edis.ifas.ufl.edu/pdffiles/EP/EP35300.pdf.

With frequent rain the soil is also losing iron. Keep in mind that the green fading to yellow appearance in your lawn may be an iron deficiency.  Before applying your summer fertilizer put out a liquid chelated iron.  It will improve the health of the lawn while you are trying to find a dry day to fertilize.  While it is necessary to water in fertilizer with ¼” of water to reduce burn potential and volatilization, never apply fertilizer when heavy rain is expected.  The rainfall over ¼” can encourage runoff and/or leaching of that fertilizer, which can be costly and environmentally harmful.

Tired of Turf? Try Groundcover Alternatives Instead!

If you’re like me, growing turfgrass is often more of a hassle than anything else.  Regardless of the species you plant, none tolerates shade well and it can seem like there is a never-ending list of chores and expenses that accompany lawn grass:  mowing (at least one a week during the summer), fertilizing, and constantly battling weeds, disease and bugs.  Wouldn’t it be nice if there were an acceptable alternative, at least for the parts of the lawn that get a little less foot traffic or are shady?  Turns out there is!  Enter the wonderful world of perennial groundcovers!

Perennial groundcovers are just that, plants that are either evergreen or herbaceous (killed to the ground by frost, similar to turfgrass) and are aggressive enough to cover the ground quickly.  Once established, these solid masses of stylish, easy to grow plants serve many of the same functions traditional turf lawns do without all the hassle: choke out weeds, provide pleasing aesthetics, reduce erosion and runoff, and provide a habitat for beneficial insects and wildlife.

The two most common turfgrass replacements found in Northwest Florida are Ornamental Perennial Peanut (Arachis glabra) and Asiatic Jasmine (Trachelospermum asiaticum); though a native species of Mimosa (Mimosa strigillosa) is gaining popularity also.  All of these plants are outstanding groundcovers but each fills a specific niche in the landscape.

Perennial Peanut Lawn

Perennial Peanut is a beautiful, aggressive groundcover that spreads through underground rhizomes and possesses showy yellow flowers throughout the year; the show stops only in the coldest winters when the plant is burned back to the ground by frost.  It thrives in sunny, well-drained soils, needs no supplemental irrigation once established and because it is a legume, requires little to no supplemental fertilizer.  It even thrives in coastal areas that are subject to periodic salt spray!  If Perennial Peanut ever begins to look a little unkempt, a quick mowing at 3-4” will enhance its appearance.

Asiatic Jasmine

 

Asiatic Jasmine is a superb, vining groundcover option for areas that receive partial to full shade, though it will tolerate full sun.  This evergreen plant sports glossy dark green foliage and is extremely aggressive (lending itself to very rapid establishment).  Though not as vigorous a climber as its more well-known cousin Confederate Jasmine (Trachelospermum jasminoides), Asiatic Jasmine will eventually begin to slowly climb trees and other structures once it is fully established; this habit is easily controlled with infrequent pruning.  Do not look for flowers on this vining groundcover however, as it does not initiate the bloom cycle unless allowed to climb.

Sunshine Mimosa

For those that prefer an all-native landscape, Sunshine Mimosa (Mimosa strigillosa), also known as Sensitive Plant, is a fantastic groundcover option for full-sun situations.  This herbaceous perennial is very striking in flower, sending up bright pink, fiber-optic like blooms about 6” above the foliage all summer long!  Sunshine Mimosa, like Perennial Peanut, is a legume so fertility needs are very low. It is also exceptionally drought tolerant and thrives in the deepest sands.  If there is a dry problem spot in your lawn that receives full sun, you can’t go wrong with this one!

As a rule, the method of establishing groundcovers as turfgrass replacements takes a bit longer than with laying sod, which allows for an “instant” lawn.  With groundcovers, sprigging containerized plants is most common as this is how the majority of these species are grown in production nurseries.  This process involves planting the containerized sprigs on a grid in the planting area no more than 12” apart.  The sprigs may be planted closer together (8”-10”) if more rapid establishment is desired.

During the establishment phase, weed control is critical to ensure proper development of the groundcover.  The first step to reduce competitive weeds is to clean the site thoroughly before planting with a non-selective herbicide such as Glyphosate.  After planting, grassy weeds may be treated with one of the selective herbicides Fusilade, Poast, Select, or Prism.  Unfortunately, there are not any chemical treatments for broadleaf weed control in ornamental groundcovers but these can be managed by mowing or hand pulling and will eventually be choked out by the groundcover.

If you are tired of the turfgrass life and want some relief, try an ornamental groundcover instead!  They are low-maintenance, cost effective, and very attractive!  Happy gardening and as always, contact your local UF/IFAS County Extension Office for more information about this topic!

Dig Safely: Call 811

This month, recognized by the Senate and Florida’s governor, reminds diggers why calling 811 before all outdoor digging projects is important to your safety. Before installing a mailbox, fence, deck, garden or tree make sure to call Sunshine 811 to have underground lines marked. 811 is the free national number designated by the Federal Communications Commission.  It notifies utility companies, who in turn send their professional locators to identify and mark the appropriate location of underground line with paint and flags in colors that identify the utility type.  The following colors represent the seven various utilities: red – electric, orange – communications (telephone, cable tv), blue – potable water, green – sewer, yellow – gas, purple – reclaimed water, and white – site of intended excavation.  To learn more about color designation and their corresponding  utility go to: http://www.call811.com/faqs/default.aspx.   Locating marks are good for 30 calendar days.  Any work beyond that requires another call to 811.  If the marks are destroyed before your project is done, stop digging and call 811.

 

Hitting an underground utility line while digging can cause injuries.   Utility service outages can also impact an entire neighborhood and damage the environment. The depth of utility lines varies, and there may be multiple utility lines in one common area.  Even if you think you know where an underground line is, time tends to change things.  Erosion or tree roots can shift those utility lines.  Failure to call before digging results in one unintentional utility hit every eight minutes nationwide.  You could also be financially affected with costly fines and high repair costs.

 

The Common Ground Alliance (CGA) Damage Information Reporting Tool (DIRT) provides industry stakeholders with a way to anonymously submit data into a comprehensive database for analysis of the factors that lead to events. An event is defined by the CGA DIRT User’s Guide as “the occurrence of downtime, damages, and near misses.” The number of events submitted to DIRT for 2011 totaled 207,779. However, according to CGA DIRT “when a call is made to the one call center (811) prior to excavation, 99% of the time there will be no damage”.

 

Calling 811 in Florida is the law. At least two full business days before digging, do-it yourselfers and professional excavators must contact 811 by phone to start the process of getting underground utility lines marked.  This is a free service.  Be sure that all utilities have been marked before grabbing the shovel.  If you don’t see locate marks, don’t assume there are no underground utility lines.  Verify with the Sunshine 811 Positive Response system.  Follow up on your one call ticket by contacting 811 again on the third day.  Sunshine State One Call is a not for profit corporation which began with the 1993 adoption of the “Underground Facility Damage Prevention and Safety Act,” Chapter 556, Florida Statutes.  Online you can visit: www.online811.com, or call (800) 852-8057.  If you provide a valid e-mail when requesting your locate ticket, positive response updates will automatically be sent to you when all utilities have responded.  For more information on Florida’s law, visit www.Sunshine811.com.

Put Some Thought into Tree Placement

It’s really tempting to buy a tree and plant it in the middle of your lawn or directly in front of your picture window, but instead take some time to choose the best spot first. Several considerations such as maintenance and mature size should be taken into account before the site is selected.

Placing a tree in a lawn area without creating a bed can lead to maintenance issues for both the tree and the turfgrass. It is easy to simply cut out a small patch of turf the size of the rootball and install a tree, however, as the grass grows up towards the trunk over time maintaining that grass will become difficult. It is common to see mechanical injuries to tree trunks because weed eaters or mowers have chipped away at the bark when trying to cut the grass. Other potential problems are irrigation zones calibrated for turf delivering the wrong amount of water to trees and herbicides used on grass that may cause injury to trees.

Over time, as the tree canopy grows, it will create shade and any grass trying to grow in that area will thin and be more susceptible to disease and insect pressure. By creating a large ornamental bed for your tree, you will prevent some pitfalls associated with placing the tree in the lawn.

Another common mistake is planting a tree too close to a house or other structure. It can be difficult to imagine how large a tree will grow at maturity because it is not a quick process. Trees placed close to houses may grow into eaves and shed leaves onto roofs and into gutters. This adds to maintenance and can provide mosquito breeding grounds. Also, some tree roots may interfere with walkways or septic systems and should be sited far enough away to avoid these issues.

Be sure to research any tree you plan to install to find out ideal growing conditions and mature size. If you plan ahead and use good maintenance practices, a tree can become an valuable part of your home landscape to be enjoyed for years to come.

Why A One Size Fits All Approach to Lawn Care is a Bad Idea

Regardless of what the tag says one size does not fit all. As with clothing, a piece will undoubtedly be too large for some and too small for others. Trying to go with a “one size fits all” approach to lawn care will lead to the same kind of frustration and disappointment as an ill-fitting garment.

All turfgrass is not created equal. Thus management of our various turf species requires different methods. It is common for a homeowner to be unaware of what type of turfgrass they have – it’s all grass after all – what difference does it make? Misidentification leads to problems because proper management for one type may be counterproductive to another type. In order to create a practical turf management plan, it is critical that the species of grass is properly identified.

Although many grasses look similar it is important to know exactly what kind you have to maintain it properly. This photo shows Empire Zoysia. Photo credit: Julie McConnell, UF/IFAS

Why is it important to know the species of turf in a lawn?

Two of the most common mistakes extension agents observe is excessively low mowing height of St. Augustinegrass  and over-fertilizing Centipedegrass. Both of these errors can reduce turfgrass vigor and decrease its tolerance to pest issues. Another potential maintenance pitfall is using a herbicide that is not labeled for use on a given type of turfgrass. Several popular herbicides available on the market can cause damage to St. Augustinegrass and/or Centipedegrass.  Thus turf can be inadvertently killed by herbicides when they are applied to the wrong species.

Before a lawn maintenance plan is developed, be sure to know what type of grass is present and then follow UF/IFAS recommendations for proper care. If assistance is needed with identification, contact your local extension office.
