Growth Stages

1

Seedling

2-3 weeks

Tiny plants with cotyledons (seed leaves) emerging, followed by first true leaves. Distinctive silvery-gray foliage begins to show.

Keep soil moist but not soggy. Provide bright light 14-16 hours daily. Maintain temps 70-75°F. Begin light fertilizing once true leaves appear.

2

Vegetative Growth

3-4 weeks after transplant

Plant develops multiple sets of true leaves and bushy growth. Silvery foliage becomes more pronounced. Compact determinate habit becomes apparent.

Harden off seedlings over 7-10 days before transplanting. Maintain consistent moisture. Pinch off lower leaves as plant grows. Apply balanced fertilizer every 2 weeks.

3

Flowering

2-3 weeks

Small yellow flowers appear in clusters on compact plant. Plant reaches mature height (typically 2-3 feet). Silvery foliage provides striking visual contrast.

Continue consistent watering to support fruit set. Reduce nitrogen fertilizer; switch to higher phosphorus formula. Gently shake plant or use bees/pollinators to encourage pollination.

4

Fruiting

3-4 weeks

Green marble-sized fruits develop and gradually enlarge to medium size. Fruits begin color change from green to orange-red over 2-3 weeks.

Maintain steady water schedule; inconsistent watering causes cracking and blossom-end rot. Apply mulch to regulate soil temperature. Support fruit-laden branches if needed.

5

Harvest

Ongoing, 4-8 weeks depending on climate

Fruits turn fully red and yield slightly to gentle pressure. Skin becomes glossy. Plant may continue producing in cool climates.

Pick fruits at full color for best flavor. Harvest regularly to encourage further production. Continue watering until frost or end of season.

Harvest Tips

Pick tomatoes when fully red and they yield slightly to gentle pressure. Harvest in morning when cooler. For ripened flavor, pick at 'breaker stage' (when color just begins to change) if frost threatens. Determinate varieties like this produce most fruit within a concentrated period. Continue regular harvesting to encourage continued production.

Fun Facts

  • 🌱 The silvery-gray foliage is caused by fine hairs (trichomes) that reflect light and help protect the plant from excessive sun and some pests while giving it an almost metallic appearance.
  • 🌱 Weston Park Silverado is an older heirloom variety with historical significance in ornamental kitchen gardening, prized by gardeners who appreciate both aesthetic appeal and culinary quality.
  • 🌱 As a determinate variety, this tomato produces most of its fruit within a 3-4 week window rather than continuously, making it excellent for canning and preservation projects where you want a harvest glut.
