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!

Spiders in the Landscape and Garden

Spiders in the Landscape and Garden

Unknowingly we interact with many small creatures in our everyday lives. Spiders are one of these groups that are beneficial to the function of human activity.  This group receives much publicity as being dangerous to people and our pets.  While there is always a possibility of being bitten and having venom injected by a few types of spiders, most all others are harmless to people.  The primary benefit of spiders is their propensity for catching insects outside and in the home that are identified as harmful to people.  Spiders come in all shapes and sizes with many hiding away, never to be seen by people.   

Spiders are often included in the same group as insects, but this is not true.  They belong in the group arachnids and are closely related to ticks, scorpions and mites.  Spiders have two body sections (cephlothorax and abdomen) and have eight legs while insects have three body sections (head, thorax and abdomen).  Scorpions usually remain outdoors and may be found indoors during hot dry periods.  They are nocturnal hunters of pests that include roaches.  None of the scorpions native to Florida are capable of providing a lethal sting, but it is painful when it occurs, leaving a sore and swollen at the sting area.  I was reminded of this after stepping on one in the late evening while moving around the kitchen with no lights on.  If the person that is stung has allergic reactions to bee stings, observe them and take precautionary health measures needed.

The spider is an important predator of harmful insects and can be found about any where in and around the home, in the garden, and many other places in the great outdoors.  An Extension Entomologist I knew from North Carolina State University always mentioned, when presenting to Master Gardener Volunteer classes, that at almost any time given time, we are within two to three feet of a spider, with most so small we never see them.  They are great at keeping the beneficial and harmful insect populations in balance in nature.

If you decide to spray to manage your spider population, keep in mind that by reducing the number of spiders in the landscape, you can create a reverse problem with harmful insect populations increasing dramatically.  If big webs are a bother, simply take a broom and knock them down.  They will rebuild by the next day, but you may not need to be in that area for a while.  Always be careful and wear gloves when working in the garden, especially areas that are dark and covered, such as irrigation valve boxes, wood stacks, and other similar places.  These are prime locations where the Black Widow or Recluse spiders may be set up, waiting to ambush roaches and other insects.  If you are bitten by either seek immediate medical care. 

Finally, spiders are fun to observe in nature! One of the most interesting spiders to watch is observable during fall in Florida – the Yellow Garden Spider.  They build large webs and often place a zig zap signature in the middle.  This large spider catches many insects in the garden and landscape.  With early morning sunlight and dew hanging on the web during the fall, it makes for a beautifully create piece of art.  Enjoy nature and all the creative processes that occur from a safe distance – spiders included!

Planting Depth Problems Continue

Planting Depth Problems Continue

Several times each month I am diagnosing shrub and tree problems in Escambia County that are related to the same issue, improper planting.  Symptoms of this problem can be slow growth, leaf browning, and dieback.  Sometimes under stressful weather conditions like drought, plants completely die.

This is a difficult sight for homeowners who have invested time and money in a tree or shrub to enhance the landscape.  In some cases, the planting issues can be fixed but there are other times when a new plant will need to be installed. 

The good news for homeowners is that this is a completely preventable issue.  The University of Florida has excellent publications with photos about installing and caring for trees and shrubs.  My Panhandle colleagues and I have also shared numerous articles and videos on proper plant installation. 

Care must be taken during installation to set your plant at the correct depth.  Even if a landscaper or nursery is installing the plant for you, check their work.  Make sure the rootball is cut or sliced, it is not set below grade, that any straps holding the rootball are cut after it is set, and proper backfilling occurs without soil over the top of the rootball. 

You don’t want to find out later in the season or even year’s later that your plant declined just because of planting problems. 

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. 

Raised beds are an excellent way to get started with gardening. Photo by Molly Jameson.

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.

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

Up Your Gardening Game with Sweet Onions

Up Your Gardening Game with Sweet Onions

For many people in the Panhandle, gardening season begins when the weather warms in spring and nurseries start setting out tomato transplants.   While I understand the allure of the yummy summer veggies and spring/early summer are the most traditional times to garden, cultivating a winter garden in the Panhandle unlocks many tasty options.  Among these cool-season garden veggies is a classic southern staple that is among the easiest and most rewarding of all vegetables to grow, sweet onions!

Sweet onions are very popular in the culinary world for their mild flavor and soft texture and are among the most widely grown group of onions across the world, but the most famous of them, Vidalia’s, hail from Georgia!  Despite its fame, the “Vidalia” onion is actually nothing more than a trademarked name for a specific variety of sweet onion that was bred in Texas (‘Yellow Granex’ and its derivatives), grown in a 20-county region in South Georgia with excellent onion-growing soil, and made famous by excellent marketing from the Vidalia Onion Committee.  While they can’t be called Vidalias legally, you can absolutely grow your very own Vidalia type sweet onions at home here in the Florida Panhandle!

Sweet Onions are most easily grown at home if purchased in the fall as “sets”.  Sets are small bulbs that have been started, harvested, dried to prevent rotting during storage, and shipped to garden centers ready to be “set” out in home gardens.  Sweet onions may also be grown from seed but take much longer and have a lower success rate.  When browsing onion set varieties for purchase at garden centers or in seed catalogues, make sure to purchase a short-day “Granex” type like “Texas Super Sweet” or similar.   It is critical to remember that sweet onions are classified by how many hours of daylength they require to produce bulbs.  The three classifications are Short, Mid, and Long-Day.  Since sweet onions require cool weather to develop properly, Floridians must grow short-day varieties to compensate for decreased daylight hours in the winter.  In the less hot Northern states, long-day sweet onions are grown in the summer, where they’ll be able to soak up 15-16 hours of daylight.  Therefore, for best results in the Panhandle, select ONLY short-day onion varieties.

Once you’ve selected your onion sets in the fall, they can be planted in the garden anytime from early October to mid-December.  Individual bulbs should be planted about an inch deep in well-drained garden soil with high organic matter content (mushroom compost, composted manure, or other rich organic matter works) and spaced 4-6” between plants and about a foot between rows.  Onions in general, and sweet onions in particular, are heavy feeders and require ample nutrition to meet their potential!  To meet these fertility needs, I apply a slow-release fertilizer like Osmocote or a Harrell’s product at planting and supplement that with either a quick release granular or liquid fertilizer monthly during the bulb enlargement phase.  Sweet onions also have a shallow root system and require frequent watering to develop properly and avoid splits, doubles, and small bulbs.  Don’t let your onion bed dry out!

Finally, sweet onions planted in late fall/early winter are normally ready to harvest in April and May.  However, rather than relying on a calendar, begin harvesting your onions when the tops start to turn yellow and fall over, this indicates maturity.  After harvesting, allow your onions to “cure” with tops and roots still attached for a couple of weeks outside in a shaded, protected area.  Once they’ve had an opportunity to “cure”, remove tops and roots and store the cured bulbs in a cool, dry place (a dark pantry in an air-conditioned room or the refrigerator crisper drawer work fine) and use at your convenience!

While they can’t be called Vidalias, sweet onions grown at home are oh so rewarding and very tasty!  Provided they are planted in quality soil, receive plenty of water and fertilizer, and are harvested/stored correctly, sweet onions will provide a delicious, home-grown culinary treat throughout the year!  For more information about growing onions in the home garden or any other horticultural/agricultural topic, contact us at the UF/IFAS Calhoun County Extension Office.  Happy Gardening!
