Black Diamond Guava

Why You Should Grow Black Diamond Guava Plant

• Health Benefits: These fruits are packed with Vitamin C and fiber. Eating one fresh from your own tree feels much better than buying store-bought ones.
• Tough for Indian Weather: Whether it’s the heat in Delhi or the humidity in Mumbai, this plant handles our climate quite well.
• Looks Like a Showpiece: Because the leaves and fruit are so dark, it stands out. If you want to impress your neighbors, this is the plant to put on your terrace.
• Lots of Fruit: Once it settles in, it produces a heavy crop. You’ll have enough to share with your relatives (or not!).
• Fits in Small Spaces: You don’t need a huge farm. I’ve seen these grow happily in large 16-inch pots on balconies.

Key Characteristics

• Appearance: The skin is a deep, dark purple (looks like a big jamun!) with bright pink or red flesh inside.
• Taste: It’s very sweet and has a strong, nice smell that fills the room.
• Variety: This is a grafted, exotic variety that stays compact but stays very healthy.
• Growth Speed: It grows at a medium pace. You’ll see it getting taller and bushier every few months if you feed it well.

Uses: Fresh Eating, Fruit Salads, Juices, Decorative Gardening, Gifting.

How to Plant & Use

When you get your plant, don’t rush to repot it in the afternoon sun. Give it 2 days in the shade first. If you’re planting in the ground, keep a gap of at least 8-10 feet between trees. For pot lovers, start with a 12-inch pot and move to a bigger one as it grows.

Pro Tip: Pair this with our Red Anna Apple Plant to have a mix of different colors and tastes in your garden.

Nursery Secrets – My Personal Care Tips

• The Finger Test: Don’t just pour water every day. Stick your finger an inch into the soil. If it feels dry, only then give it a drink.
• Support is Key: Since these are grafted, the joint can be a bit weak when young. I always use a bamboo stick to tie the main stem, so it doesn’t snap during heavy rains or wind.
• Food for Fruit: Every two months, I give my plants a handful of well-rotted cow dung (Gobar Khad) or Vermicompost. It keeps the leaves dark and the fruit sweet.
• Pruning: Don’t be afraid to snip off the tips of the branches. This makes the plant “bushy” instead of just one long tall stick.
• Sunlight is Non-Negotiable: If you keep this in the shade, the leaves will turn green, and it won’t fruit. It needs that harsh Indian sun to get that dark “black” color.
