🌵 Green Tomato Cactus

(Echinopsis species – often Echinopsis oxygona or Echinopsis eyriesii)

🌿 What Is a Green Tomato Cactus?

The Green Tomato Cactus gets its name from its round, plump, green shape, which looks like a small tomato. It’s a popular, easy-care cactus known for producing large, fragrant flowers, often much bigger than the plant itself.

🔍 How to Identify a Green Tomato Cactus

  • Shape: Round to slightly oval

  • Color: Bright to deep green

  • Ribs: Prominent vertical ribs

  • Spines: Short to medium spines along ribs

  • Size: Usually 4–10 inches tall

🌵 It may grow pups (baby cacti) around the base over time.

🌸 Flowers & Blooming

One of the best features!

  • Produces huge, showy flowers

  • Blooms usually in late spring to summer

  • Flowers often open at night or early morning

  • Flowers last 1–2 days, but are stunning

Common flower colors:

  • White

  • Pink

  • Pale lavender

  • Light yellow

✨ Flowers are often fragrant.

☀️ Light Requirements

  • Bright light to full sun

  • At least 6 hours of sunlight daily

  • Indoors: South- or west-facing window

  • Outdoors: Gradually acclimate to full sun

⚠️ Too little light = no blooms.

💧 Watering Needs

Like most cacti, it prefers a soak-and-dry routine.

Spring & summer (active growth):

  • Water deeply

  • Allow soil to dry completely before watering again

Fall & winter (dormancy):

  • Water very sparingly

  • About once a month or less

⛔ Overwatering is the #1 cause of problems.

🌱 Soil & Potting

  • Use a cactus or succulent mix

  • Must be fast-draining

  • Pot with drainage holes only

  • Repot every 2–3 years if needed

🌡️ Temperature & Environment

  • Ideal temperature: 70–85°F (21–29°C)

  • Can tolerate cooler temps down to 40°F (4°C) if dry

  • Not frost-tolerant

  • Enjoys fresh air and outdoor summer time

🌼 How to Encourage Blooms

  • Bright sunlight

  • Cool, dry rest period in winter

  • Minimal watering during dormancy

  • Mature plants bloom more reliably

🌙 Some species bloom at night—don’t miss it!

✂️ Propagation

Very easy!

Methods:

  • Offsets (pups)

  • Seeds (slower)

Offset propagation:

  1. Gently remove a pup

  2. Let it callous for 2–3 days

  3. Plant in dry cactus soil

  4. Water lightly after 1 week

⚠️ Common Problems

  • Soft or mushy cactus: Overwatering

  • No blooms: Too little light or no winter rest

  • Shriveling: Underwatering during the growing season

  • Pests: Mealybugs, spider mites (rare but possible)

🐾 Pet Safety

⚠️ Generally non-toxic, but:

  • Spines can injure pets

  • Keep out of reach of cats and dogs

🧡 Fun Facts

  • Flowers can be larger than the cactus body

  • Some flowers open for only one night

  • One of the most rewarding blooming cacti

  • Great beginner cactus
