When planning your space, on average each plant will yield enough pigment to dye one ounce of fiber.  I recommend planting 5-10 plants for a small garden.

 

Sowing

Seed indigo indoors in trays or cells. Maintain a damp not sopping moisture level

Potting On

Potting on gives indigo time to establish good root formation. (Three weeks after potting or before planting in the ground, pinch out preliminary center leaves to encourage plants to bush.)

First harvest should be 6-8 weeks after planting in the ground.  Plant outside after threat of frost, in a sunny location.

Indigo prefers warm sunny environments and lots of regular water, especially as it matures.

Soil Preparation

Indigo loves nitrogen rich soil (ph 7). Apply compost prior to planting to encourage good microbes.

Planting and Feeding

Indigo thrives in full to partial sun. Shelter from wind. Plant in 12 inch intervals between each plant. Water consistently, daily if necessary.

Feed every 6-12 weeks, before and after each harvest.

So much sturdy fun for little dogs!
Size: Small 2"
Wow! My puppy loves these! He is entertained endlessly chasing after and nose scooting the little rubber balls! He really seems to enjoy the jingle sound and loves to chew on the balls also. Even with a lot of chewing from his little teeth, there are no marks. Sturdy, great toy!

Well made, perfect size!
Size: Small 2"
My dogs love these balls. They are the perfect size and hold up well for my 2 dogs, 7# and 9#. The bell is a nice change from the squeaky toys.

Durable, bouncy, not annoying like squeaky ball & our dogs LOVE them.
Size: Small 2"
Love these and my dogs love them to! Not nearly as noisy as a squeaky ball (thank goodness) and they bounce which are dogs love. They will fetch them, and they will play by tossing it up and pouncing on it when it bounces. They literally entertain themselves with it when we aren't playing fetch. Much more durable than the round rubber / latex squeaky ball / toys.

Quality item.
Size: Small 2"
These seem to be quality dog toys. I bought them for a friend's chihuahua. My cats were unimpressed, lol. The chihuahua had never seen a ball. He seemed curious, but would not approach this new item. Time will tell. The bells have a very loud shrill sound, completely unlike any I've ever heard before.

What I was looking for!
Size: Large 3"
I bought these to continue playing fetch with my blind dog, she loves it! The only downside is the bell has slipped out once in a great while, but is easily reinserted.
