Kentucky Wonder 125 Bush Bean


  • Beet seeds and Swiss chard seeds will benefit from soaking in water


  • Danvers 126 that is an improved strain of the Half Long.
  • Pre-sprouting advice is here. Freeze 24 hours then warm-wet until sprouts.
  • Good suggestions in Growing Guide here.
    • Plant seed 1/4” deep, 3 seeds per inch, and thin to 1-2” apart in rows 12” apart.
    • Cover seeds with a fine light soil, and keep soil moist. 


From 2019 Soil Test Report: “For corn in home gardens on sandy soils apply 1 tablespoon zinc sulfate per 100 ft. of row.

Blue Clarage (Ohio Blue Clarage) Dent Corn at SESE.


Poinsett 876 planted last year did well and is recommended here for its disease resistance.


Dill gives good results when planted in February and March. The variety ‘Long Island Mammoth’ is suggested for Florida.


  • Plant Okra one-row wide so you do not have to walk between them.
  • Plant seed saved from last year’s Cajun Jewell Okra.


  • Begin lettuce production early and keep it going later in the season by planting tall vegetables in north-south rows and plant heat-resistant lettuce underneath the leaf canopy so that it is shaded during the hottest portion of the day. Corn planted in rows 4 feet apart or pole beans on a fence or trellis is ideal. Interplanting lettuce with bush squash also gives good results.
  • Direct sow lettuce in the garden 4 weeks before the average last frost date when the soil temperature is at least 35°. Plant first week of Feb.

Mustard – Had enough mustard from winter garden so did not plant more.

  • Plant 1st week of Feb
  • Mustard prefers a soil pH of 5.5 to 6.8. But, Florida Broadleaf did very well in the fall 2019 garden with a ph of 7.0.


  • Sweet Bell – Carolina Wonder – Best Root-knot Nematode resistance. SESE pg 41
  • Jaloro Jalapeno – Resistant to many diseases and milder. SESE pg 43. [1992, Texas A&M.] Big yields of colorful yellow Jalapeño peppers, one of the best in our 2018 jalapeño trials. 1½ x 2 in. fruits are juicy with thick walls. Medium hot fruits, milder than our regular Jalapeño. Shorter plants than our regular Jalapeño – a good container variety! – with bigger early harvests. Resistant to many diseases including TMV.
  • See SESE Cultural Tips here.
  • See Fertilize with Epsom Salts as it is recommended for soil high in calcium and low in Magnesium. But, our soil test in Dec 2019 shows high calcium and high magnesium.

Southern Cow Peas

  • Pink-eye Purple Hull
  • Mississippi Creme Pea
  • Good advice at SESE here including:
    • Sow seed 1 in. deep, 2 in. apart in rows 3-6 ft. apart, thinning to 4 in. apart.
    • They need warmer soil, so wait until 3-4 weeks after last frost to plant. 
    • Do not apply nitrogen, which will result in poor yield and lush foliage.


  • Plant the seeds ½ inch deep and try to keep them about an inch apart in the row.
  • Once the seeds have been placed to fill up a row, cover them lightly with the loose garden soil, plant the next row in the same manner.
  • When all done, sprinkle the row or rows lightly with water enough to settle things in, but not soaked to the point of becoming muddy.
  • Remember to sprinkle lightly with water, as watering too hard can wash the seeds right up out of the soil they were just planted in.

  • Per https://harvesttotable.com/how_to_grow_spinach/
    • Refrigerate seeds 1 week before sowing to help germination.
    • Plant spinach seed ½ inch deep. Cover seed lightly with soil.
    • Sow seed 2 to 4 inches apart.
    • Sow 4 weeks before last frost date; i.e. 1st week of Feb
  • The varieties of spinach recommended for north Florida include Bloomsdale, Virginia Savory, Melody, Tyee, Olympia and Longstanding from here.

Summer Squash

Plant fungus-resistant varieties. For info:


  • Celebrity
  • Tomatillos
  • Roma VF

Mulch to reduce diseases per SESE. BUT, too much mulch on the soil in the spring may delay growth by preventing soil temperature from rising enough to support active root growth. In June, apply a deep mulch around plants to conserve moisture, prevent disease, and increase yield. [Expect citing June is for SESE’s area in Virginia.]

See Fertilize with Epsom Salts as it is recommended for soil high in calcium and low in Magnesium. But, our soil test in Dec 2019 shows high calcium and high magnesium.

Thyme, German Winter

  • Germination when temps are 60-75°F, 14-30 days.
  • Transplant when 8 in. tall. Space 12 in. apart.
  • Reaches 10 in. to 12 in. high
  • Shrubby, evergreen perennial.
  • See Burpee for good advice
