Parsley herbs require lots of sun, and a window faced south preferably in order to receive 6-8 hours of direct sunlight every day. If you don’t have a window that will provide the proper light, then you will have to supplement it with fluorescent lightning. You should turn the pot every 3 or 4 days so that the plant won’t lean into the sun.
There is no difference between growing parsley and growing any other herb in a container. You should choose a container that fits snuggly on the window sill. The pot should have a few drainage holes and a saucer underneath to catch it when it drains through. Put a good quality soil in the pot and add a handful of clean sand to improve the drainage.
Humidity isn’t a problem when parsley is grown in the kitchen where steam from cooking and the use of water helps keep the air moist. In other location, you should mist the plants once in a while. If you notice the leaves looking dry and brittle, set the plant on top of a tray of pebbles and add water to it, in order to increase the humidity as it evaporates.
How to Grow Parsley Indoors
It is best if you start growing parsley from seeds sown directly in the container, as parsley has a long tap root that doesn’t transplant well. Sprinkle a few seeds on the surface of the soil and cover them with an additional 1/4 inch of soil.
Regularly water the pot in order to keep the soil moist, but not soggy. Seedlings should emerge in three weeks or so. Slip out the excess seedlings with scissors, however, do not pull them since you can damage the tap roots of the surrounding plants.
Indoor Parsley Care
It’s easy to take care of indoor parsley. The soil should be slightly moist, and you should empty the saucer under the pot after every watering. Feed the plants every 2 weeks with fish emulsion or half-strength liquid fertilizer.
If you want you can grow other herbs in containers with parsley including chives, thyme, basil, oregano, and mint.
