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.

Will definitely get more for my pig ear loving boy!
Flavor Name: Pig Ear, Size: 8 Count (Pack of 1)
My shar pei mix baby LOVES these! He is about 4 months old, teething and always has food on the brain. These do the trick! One ear lasts him about 2 days if he is really going at it, sometimes longer. He will work on it for hours at a time. They have little to no smell. He chews them on his white dog bed and they leave no stains or marks. I love that there aren't any extra ingredients so I know exactly what he is ingesting. I will DEFINITELY be buying more of these!

Is Milo allergic to pig ears?
Flavor Name: Pig Ear, Size: 10 Count (Pack of 1)
Milo sniffed the pig ear, paused, and then took it to his spot to eat it. A few minutes later he started rubbing his head on the floor. I also bought the cow ears and he ate them with no problem. I’ve snuck him the occasional piece of bacon so I don’t think he’s allergic to pork. I love and trust Nature Gnaws.

Great quality!
Flavor Name: Pig Ear, Size: 8 Count (Pack of 1)
I do not review items very often, but after considering that I have ordered these no less than 30 times, I decided it was time. I have four dogs who absolutely love them, so I go through them pretty quickly. They are generally very large, with occasionally one smaller one in the bag. These are the best price/quantity pigs ears I have been able to find. Each bag has eight ears. My dogs range in size from a (very food-motivated) mini dachshund to a pit bull, so the treats are good for any size. I order them for my sister’s and my boyfriend’s dogs, and my boyfriend breaks them in half to give to his dog if you don’t want them to have the whole one all at once. Would highly recommend!

Best pigs ears on the market!
Size: Slivers (1.8 Pounds)
These are the best and biggest pigs ears on the market. I give my dogs 1 per day and they know exactly when it’s coming. They are, by far, their favorite treat. They’re not too stinky or greasy.
