Plan on Doing a Fall Garden, Plan Now!

Plan on Doing a Fall Garden, Plan Now!

Yay, we are halfway through with August and our summer is winding down!  This is the perfect time to start prepping for that fall garden.   Growing a productive fall vegetable garden requires thoughtful planning and good cultural practices.  This process consists of selecting a site, planning the garden, preparing the soil, choosing the seeds and plants, planting a crop, and nurturing the plants until harvest time.  In the Florida Panhandle it can be a challenge to get cool season crops started; there is a balance in starting them early enough to allow them to mature (50-60 days) before a hard frost and getting them through the end of a hot summer.

August and September are the main planting times for a fall garden.  There are several cool-season crops and a final crop of warm-season vegetables that can be planted.  Some good warm season crops are lima beans, cucumbers, eggplant, peppers, and tomatoes.  Going into September it will be a good time to establish strawberry plants.  Some good vegetables to start growing just around the corner are broccoli, carrots, cabbage, collards, mustard, and Swiss chard.  https://edis.ifas.ufl.edu/NorthFloridaGardeningCalendar  Herbs that do well are cilantro, parsley, and lemongrass. Mint, oregano, and thyme should be planted in containers as they tend to spread. Mexican tarragon, mint, rosemary, and basil will also do well in September. See Herbs: http://edis.ifas.ufl.edu/topic_herbs

Transplants from the local garden center will get the garden off to a fast start while seeds will offer more varieties to choose from.  It is also important to think about your location.  A vegetable garden can be in the ground, a raised bed, or even grown in containers.  Your plants will need more than just a place to grow.  They will also need sunlight, water, air, soil, fertilizer, and care.  Most vegetables require at least 8 hours of sunlight.   Keep an eye out for pest problems such as insects, diseases and weeds because they will continue to flourish in warm temperatures and high humidity. To help conserve soil moisture a layer of newspaper and mulch can be placed between the rows.  Mulch also aids in weed control.

The result of a beautiful, successful vegetable garden is fresh produce to eat, share with neighbors, family, and friends and even the possibility to sell your harvest.  With patience and practice your gardening skills will improve every year!  Follow the above few tips and you will be well on your way to a great harvest!  For more information about starting a fall garden or any other horticultural or agricultural topic, contact your local UF/IFAS County Extension Office.

The Fall 2022 Leon County Seed Library Kicks Off August 13

The Fall 2022 Leon County Seed Library Kickoff event starts at 11 a.m. on August 13 at the Collins Main Leon County Library.

The Fall 2022 Leon County Seed Library Kickoff event starts at 11 a.m. on August 13 at the Collins Main Leon County Library.

 

To kick off the Fall 2022 Season of the Leon County Seed Library Program, UF/IFAS Extension Leon County will be at the LeRoy Collins Leon County Main Library (200 W. Park Ave.) Program Room on Saturday, August 13, from 11 a.m. to 1 p.m., with information on raised bed gardening, a hands-on seeding activity, an Ask-a-Master-Gardener booth, and a healthy cooking demonstration.

Although we are still in the full swing of summer, gardeners know it is time to start thinking about planning the fall garden. Although pulling weeds and adding fresh compost can wait a little while, gathering seeds for the new season can be something to think about doing now.

If you live in or around Tallahassee, the Leon County Seed Library Program can help jump-start your fall garden. Starting August 13, you can go to any of the seven Leon County libraries to check-out three sample vegetable seed packets per month per library card! The Leon County Master Gardener Volunteers are currently busy labeling and packing each of the seed varieties that will be distributed to the seven libraries.

There will be 10 vegetables varieties this season, including a few varieties that have never been featured in the program. If you like to save seeds from your garden, know that all varieties in the Seed Library Program are open-pollinated (by insects, birds, wind), which means if they are not crossed with another variety, the seeds they produce will grow true to form.

The Fall 2022 selection includes:

  • Common Arugula: Deep green with a spicy, peppery, mustard-like flavor
  • Cylindra Beets: Heirloom with long cylindrical roots, good for slicing
  • De Cicco Broccoli: Central light green head and side shoots to extend season
  • Scarlet Nantes Carrots: Sweet, crisp, bright red-orange, seven-inch roots
  • Vates Collards: Slow bolting, large blue-green leaves
  • Lacinato (Dinosaur) Kale: Cold tolerant, sweet dark green narrow leaves
  • New Red Fire Lettuce: Crisp and flavorful, green base with red ruffled leaf edges, bolt resistant
  • Peione Parsley: Large flat leaves with sweet flavor
  • French Breakfast Radishes: Mild, spicy flavor with a red top and white bottom
  • Bright Lights Swiss Chard: Rainbow stems, burgundy and green leaves, very mild

Vegetables for the Summer Heat

Vegetables for the Summer Heat

Unlike areas with cooler climates, North Florida’s weather is a bit of a rollercoaster. Where the traditional four seasons allow for one growing season, the panhandle’s temperature changes create two growing seasons – spring and fall. During the winter, temperatures fall too low to keep plants happy, so those who expect to grow tropical plants in Florida may be disappointed. During the summer, the heat and humidity climb to levels that even plants can find stressful! Many of our vegetable crops simply can’t handle the extremes and wither away.

There are a few edible plants we can grow, however, that don’t seem to mind the hot weather. If you simply can’t live without a productive garden during the summer, you might consider trying these:

Cowpeas

Also called Southern peas, black-eyed peas, or field peas, these are known for their ability to produce a crop despite the harshest of conditions. Actually a bean rather than a pea, they take 65 to 125 days to grow to full maturity, depending on variety. Because they are a nitogen-fixing legume, they have also been used as a cover crop.

Malabar Spinach

Popular in Asian countries, Malabar spinach is actually a vining plant unrelated to true spinach. It grows quickly and is edible both raw and cooked, though some people may not appreciate its mucilaginous texture. Similar to okra’s sliminess, this quality does make it useful for thickening soups. Malabar spinach may be propagated from seed or by cuttings, which root easily. The plant also produces berries which, while not toxic, have very little flavor and tend to stain whatever they touch.

Okra

A traditional Southern favorite, okra takes the heat and keeps producing. Related to cotton and hibiscus, it grows pods that are ready to harvest after 60-70 days. Seeds have a tough exterior and need to be soaked overnight before planting. Harvest every couple of days at least for best results, as pods that grow too large become tough and fibrous.

Seminole Pumpkin

Though they may need extra attention paid to them due to their attractiveness to pests, Seminole pumpkins are a great option for a summer planting. Similar to butternut squash, these cucurbits aren’t your traditional carving pumpkin, but they make great eating. Give them plenty of room to spread out in a sunny space. They take 120 days after planting before they’re ready to harvest, and their thick skin allows them to be stored for a long time after.

 

Sweet Potato

Does well in sandy soil? Check. Doesn’t mind the heat? Check. Sweet potatoes are great for our neck of the woods. Start out with disease-free slips for best results, and pick varieties such as ‘Beauregard’ that do well in our area.

Yardlong Beans

Related to cowpeas, yardlong beans grow on a climbing vine. The beans themselves, as the name suggests, are contained in a pod that can reach 36 inches in length. These can be picked and cooked much like green beans while the pods are still tender.

One of the most frustrating things about gardening is finding something wrong with a crop that cannot be fixed. I witnessed this last week when checking on a problem with some recently harvested potatoes.

Sometimes potatoes that look perfect on the outside might not be perfect on the inside. Unfortunately, this is the case when potatoes are afflicted by the physiological disorder “hollow heart” or “brown center”.

The disorder that causes hollow heart or brown center in the potato tuber manifests when cells die inside while potatoes are growing too quickly or unevenly, such as when recovering from environmental stress or over fertilization.

Weather extremes during tuber development cause plant stress. Weather conditions that may cause brown center are early season cool nights, which cause soil temperatures to be below the mid-50s for around a week or longer. Soil moisture at 80% or greater may also cause the same brown center symptoms.

Hollow heart is typically caused by swings from low to high soil moisture and overapplication of nitrogen. To mitigate this condition, consistent irrigation practices and spit fertilizer applications have been shown to be effective.

Additionally, if hollow heart or brown center is a typical problem for a given growing area, selection of cultivars that are less susceptible to this condition is beneficial, since there is quite a bit of variation among cultivars / varieties.

The final message is one of good news, if brown center or hollow heart is noticed at potato harvest this year, there are steps that can be taken to mitigate this issue for future growing seasons.

Be Careful of Residual Herbicides: Buying and Selling Hay/Straw for Garden Mulch and Compost

Be Careful of Residual Herbicides: Buying and Selling Hay/Straw for Garden Mulch and Compost

This article was written by Kacey Aukema, University of Florida/IFAS Extension – Walton County.

I recently met with a home gardener who brought in tomato plants showing strange symptoms on the leaves. Together we puzzled over the odd leaf-curling symptoms that were affecting their tomato beds, but not other areas of the garden. Upon further investigation it was revealed that hay, used as mulch, had recently been spread around the tomatoes, but not in other areas of the garden. It quickly became apparent that the symptoms were likely related to herbicide residual on the hay that was used. The herbicide aminopyralid was the potential culprit. In this case the residual herbicide was not enough to outright kill the growing tomato plants. However, it was interfering with their growth and development and is a cautionary tale reminding us how important careful sourcing of hay used in mulch or compost can be.

What is aminopyralid and how does residual herbicide affect non-target plants through mulch, compost, etc.?

Aminopyralid is a herbicide active ingredient found in several popular pasture products such as GrazonNext™, Milestone™, Chapparral™ and similar products. This and other similar chemicals have residual activity and can be retained in plant tissues, animal manure, and soil, which makes them a very useful for controlling certain troublesome broadleaf weeds in grass pastures for an extended period of time. Unfortunately, this residual activity increases the potential for causing trouble in vegetables or other crops when hay or animal manure from aminopyralid treated pastures is mistakenly used for mulch, compost, etc. In Florida, aminopyralid containing pasture herbicides are often used as the “go to” for control of hard to control weeds like horsenettle and tropical soda apple which are potentially toxic to livestock. Tomatoes, potatoes, and eggplant are in the same genus (Solanum) as those weeds and are therefore very susceptible to this herbicide as are many other vegetable and other broadleaf crops.

How can I know if hay is safe to be used for mulch or compost?

Before acquiring hay to be used as mulch or to compost for vegetable beds, be sure to ask if the hay is free of herbicides with residual activity. Find out what was sprayed on the field in the last two seasons before the hay was harvested. Given that hay destined to be used as mulch or compost is usually old and spoiled, management history of a particular hay bale is likely to be hard to pin down. Do not trust hay to be used for mulch or compost in vegetable beds if prior spray management details are unknown. Also consider that well-stored hay may retain residual herbicide better and for a longer period of time than weathered hay, as the active ingredient is less subject to weathering and biological breakdown.

Those who use broadleaf herbicide products with residual activity such as those containing aminopyralid are subject to follow herbicide label guidelines. For instance, supplemental labeling of GrazonNext HL™ (including FL, AL, and GA) indicates that hay/straw from fields sprayed in the past 18 months should not be used for compost, mulch, or mushroom spawn. When in doubt refer to the label of the particular herbicide product used on hay you purchase for any restrictions and/or reach out to your local county extension agent if you have questions about a specific herbicide product. Relevant use restrictions and considerations like in this example should be conveyed between hay producer and buyer.

Perhaps you already have some hay for mulch/compost with an unclear management history, or you would like to double-check and be sure that it is safe. How could one test it to see if it was safe to use?  There is a test called a “bioassay”, conducted by growing susceptible plant seedlings like tomatoes or beans in small pots with the hay/compost/mulch in question incorporated into the potting soil. Then, the test plants can be observed to see if any herbicide symptoms develop to know whether the material is safe to use, before using the hay over a larger area or garden where there would be more risk. For more information on how to conduct a bioassay see: Herbicide Residues, in Manure, Compost, or Hay. Similar in-field bioassays are also recommended when rotating areas out of pasture and into other crops when pasture herbicides with residual activity were used. If susceptible crops like peanuts are grown in areas where such herbicides were used in the recent past they can be damaged, as in this case in an older Panhandle Agriculture Newsletter post.

When used according to label instructions, herbicides with residual activity are very useful for control of broad-leafed weeds in pasture and hay fields and may reduce the spread weeds through seed coming in on purchased hay. However, problems can emerge when hay from fields treated with these products change hands without the use restrictions and considerations being adequately explained. Therefore, caution should be taken by both producer and buyer to avoid damaging sensitive crops when hay or livestock manure are used for mulch or compost.
