| Howdy smelly cat40, One method that you might consider is to use a container inside a container. Depending on the size of your windowbox, you can put in containers like a 5-inch by 5-inch by 6-inch deep square pot. This is plenty large to grow a head of lettuce, parseley, rosemary, dill, oregano, etc. You can then take the pots and rearrange them as you trim them. You can also move them around to take advantage of higher sunlight on one side than the other or to even the growth. You can also rotate new starter plants in as the older ones start to bolt. Many growers put growrocks in the bottom of the planter to raise the height of the inner container. You also have the option of watering some herbs less or more than others beacause each kind is in its own container. You can also use different fertilizer schedules for the different inner containers. It is also possible to grow many herbs in deep square containers like 3-inch by 3-inch by 4-inch deep or 4-inch by 4-inch by 5-inch deep. Depending on how wide your windowbox is, you can sometimes double up the square containers. If you can double up the containers, as you trim your herbs, you can move them around so that one set of green fills in the holes of the trimmed herbs. By the way, what are they feeding you? It's not your fault. |
