Starting Transplants for the Home Garden

Starting Transplants for the Home Garden

Winter is in full swing and home grown produce is probably not the first thing that comes to mind.  But it should be!  It’s time again to start thinking about spring vegetable gardening.  While a number of crops can be started by direct seeding in the soil, success rates are higher when plants are started indoors or in a covered structure.  In order to be successful, it’s important that you follow some simple steps.

  • Transplant Trays/Flats – Trays are made from different materials such as plastic, polystyrene, and compostable materials.  Different cell sizes are also available.  Generally, smaller cells are used for smaller seeds and larger cells are used for larger seeds.  It’s important to think of the life cycle of the crop.  For example, lettuce and other leafy greens have much shorter life cycles compared to tomatoes.  Because of this, they have smaller root systems at transplant time and may not develop a good rootball in a large cell.  Therefore, lettuce would perform better in a smaller cell.
  • Media – It’s important that you choose a germination mix instead of a potting mix.  Definitely don’t use garden soil!  Germination mixes are typically a combination of finely ground peat, perlite, and other soiless substrates.
  • Seed – Purchase seed from a reputable source with a germination guarantee.  If you save seeds for future gardening, then store them in a cool, dry place.  Seed can be stored in the refrigerator.  However, do expect the germination rate of stored seeds to diminish over time.  Coated seed is recommended for smaller seeds to make seeding easier and more efficient.  Seeds should be planted in media at a depth of approximately 3 times the diameter of the seed.  Check the seed package for additional planting recommendations.  For more germination and storage information please see this publication from the University of Nebraska.
  • Fertilizer – Too much fertilizer can result in leggy and possibly burned plants.  A 20-10-10 (or similar ratio N-P-K) water-soluble product is generally used in commercial production.  Rates are dependent on crop, sunlight, and temperature.  The media should be kept moist, but not continually wet.

Seeds can take up to 14 days to germinate depending on species and conditions.  Most transplants are ready for the garden by 6 to 8 weeks.  To improve success rate and accelerate production time, most farmers harden off their transplants before planting.  Hardening off is the process of stressing the transplants for about a week.  Generally, transplant trays are taken out of the greenhouse (or other transplant area such as a window sill) and set outside.  Watering frequency is reduced and fertilization is halted.  It’s important that the plants aren’t completely neglected, but just stressed enough to prepare them for the elements.  A good place to put the trays is under a tree in partial shade.  After this hardening off period, the transplants are ready for your garden.  Hopefully these tips will make you a more successful gardener!

Make Your Lawn a Florida-Friendly Landscape

Make Your Lawn a Florida-Friendly Landscape

I imagine many of you have had plant loss due to this recent cold snap. Like myself, you’ll be busy this spring replanting areas. Want to have a more sustainable landscape and attract birds & butterflies? Consider a Florida-Friendly Landscape.

So, what is “Florida-Friendly”? These are plants that are either native to Florida or non-invasive species, and are low maintenance. One can convert their landscape to “Florida-Friendly” simply by changing the way you take care of your yard. A Florida-Friendly Landscape has 9 major principles:

  1. Right plant, right place – Select plants that match a site’s soil, light, water, and climatic conditions. Buy quality plants that welcome wildlife, consider plant size when you make your purchase, and aim for a diversity of trees, shrubs, groundcovers, and flowers.
  2. Water efficiently –  Watch for signs of wilt before you irrigate, be a weather watcher (don’t irrigate if it’s going to rain), and water early in the morning if you can, following any restrictions in your area. Check your irrigation system regularly; repair any leaks, clogs, or breaks; and make sure all sprinklers are irrigating your plants, not the sidewalk!
  3. Fertilize appropriately – Fertilize according to UF/IFAS recommended rates and application timings to prevent leaching—fertilizer leaking down through the soil rather than being absorbed by plant roots. Look for fertilizers with slow-release nitrogen and little or no phosphorous, unless your soil test indicates need (as many Florida Panhandle soils are phosphorous poor). Never fertilize within 10 feet of any water body, and don’t fertilize before a heavy rain.
  4. Mulch – Retains soil moisture, protects plants, and inhibits weed growth. It gives your landscape a neat, uniform appearance and is a great Florida-Friendly choice for hard-to-mow slopes and shady spots. Keep a 2- to 3-inch-deep layer of mulch on plant beds. Always leave at least 2 inches of space around tree trunks to prevent rot. Create self-mulching areas under your trees by letting fallen leaves lie.
  5. Attract wildlife – By providing food, water, and shelter for birds, butterflies, bats, and others, you can help these displaced Floridians while bringing beauty and benefits to your home landscape. Select plants with seeds, fruit, foliage, flowers, or berries that animals can eat.
  6. Manage yard pests responsibly – Concerns for human and environmental health have led scientists to recommend Integrated Pest Management (IPM), a strategy that helps gardeners manage pests with as few chemicals as possible. Don’t treat by default—some of the insects you see may be beneficial, actually helping to control pest insect populations. Spot-treat only, rather than blanket spraying, and use selective rather than broad-spectrum insecticides.
  7. Recycle – Landscape maintenance activities like mowing, pruning, and raking generate yard waste that you can recycle to save money. Decomposed organic matter, like pruned branches or grass clippings, releases nutrients back to the soil in a form that plants can easily use. Try composting, combining “green” (nitrogen-rich) and “brown” (carbon-rich) materials, such as grass clippings, weeds, plant trimmings, egg shells, coffee grounds, tea bags, twigs and branches, pine needles, corncobs, and shredded cardboard.
  8. Reduce Stormwater – Florida’s waterways are vulnerable to everything we put on our home landscapes. Fertilizers and pesticides can leach through the soil or run off into storm drains. Along with landscape debris and eroded soil, these can wreak havoc on our water quality and the fragile ecosystems our water resources support. Creating shallow rain gardens, or shaping the earth on slopes with berms (rises) and swales (dips), can help slow runoff from heavy rains and allow the water time to soak into the ground. Make sure your downspout is pointed into the garden, not towards a sidewalk or driveway. Wherever possible, maintain permeable walkways, driveways, and patios of brick, gravel, earth, or crushed shell, to allow rain to soak into the ground.
  9. Protect the waterfront – Florida boasts over 10,000 miles of rivers and streams, about 7,800 lakes, more than 700 freshwater springs, and the U.S.’s second-longest coastline. Even if you don’t live immediately on one of these water bodies, you do live in what’s known as a watershed (a drainage area). What you do in your home landscape has much further-reaching consequences than you might think. One of the most important steps you can take to protect any water body is maintaining a 10-foot “maintenance-free zone” around it. Do not mow, fertilize, or use pesticides in this zone. A stormwater pond or canal can become an aesthetically pleasing and lively place, edged with plants and home to wildlife. Work with your neighbors or homeowner association to make your stormwater pond a Florida-Friendly neighborhood amenity.

A Plant Favorite Comes South

A visit to a nursery and homeowners will see so many new selections of plants for the landscape. Some of these plants are new plant developments and may include plants we could not previously grow in Florida’s heat and humidity. One new plant series is the Southgate® Rhododendrons.

Anyone from more northern areas of the South is very familiar with the rhododendrons that offer showy spring blooms. Those particular rhododendrons just don’t make it in our Florida climate.

The Southgate® series from Louisiana were developed to be more tolerant of our weather conditions. Homeowners must still consider plant placement very carefully since these plants have some specific requirements even in Florida. Plants will do best in shade or filtered shade, especially in the afternoon. They do like an acid soil amended with compost and areas that are well drained. Homeowners will need to supply water during the growing season to maintain a uniform soil moisture.

Consider trying one of these newer rhodendrons if your landscape has a suitable spot and you will definitely enjoy a bright spot of color come spring.

Special Note: If you have animals or children be cautious since all plant parts are toxic if ingested.
