Pot the Difference! Story date: 8th June 2008 Laurel Farm Herbs prides itself on supplying pot grown herbs in the larger pot. All our plants are grown on in 1.5ltr pots. This means that our plants are sturdier and have a more established root system to ensure that they become estabalished in your garden much quicker. Look at the difference in pot sizes between our 1.5 ltr black pot and a 9cm brown pot, which is the size used by most other herb nurseries.
