The Marconi Red was another nice pepper for our area.  We had our first ripe red pepper 10 days sooner than we were supposed to.  But we start plants in February and early March indoors so they are quite large (8 inch tall plants) once they get put in the garden.  Maybe this helps with this variety?

Life Cycle:
     Zone 8 or lower:  Grow as annual

     Zone 9 or higher:  Perennial

Starting Seed Indoors:

  • Start 8-13 weeks prior to the date you move plants into garden in your area.
  • Planting depth:  1/2 inch
  • 2-3 seeds per 1x1x2" cell (LengthxWidthxDepth).
  • Transplant into pots at 4-6 weeks.  Pots 6" tall work well.

Planting Bed Specs:

  • Soil Temp:  + 65˚F.
  • Hole depth: 8-10 inches.  As a rule of thumb, make the hole 2+ inches deeper than the height of the root ball.  This allows for 1 inch of loose soil above and below the roots.
  • Spacing:  18" apart.
  • Planting depth:  Bury root ball and up to 1" of stem.
  • Tilling:  Optional but does improve drainage and helps roots grow.

Light Requirements:  Full Sun.  Peppers like heat but a string of days in the 90's will often halt blooming and pepper development.  This stress can take a week or more to recover from delaying and reducing harvest.  Woven shade cloth supported above the plants by poles is used by some growers to moderate sun exposure.

Watering:  Without rain, peppers need watered well 1 - 2x per week depending on how hot it is.  Your soil type will also affect water needs.  Carefully observing the plants and how long your soil remains damp is the best way to learn how to manage your unique conditions.  To prevent fungal disease water late morning or early afternoon so the sun will quickly dry the leaves and stems.  If you must water on cool, cloudy days, wet the soil below the plants, ie. keep the leaves dry.
