Growing herbs indoors allows you to enjoy homegrown produce whether you're short on garden space or just want to add some greenery and fragrance to your home. It can also serve as a low-stakes entry into more substantial edible gardening.
When growing herbs indoors, there are number of things to bear in mind.
Firstly if growing herbs in the kitchen, make sure your herbs are placed near a south facing window to maximise the amount of light they receive during a day. Most herbs require around six hours of sunlight every day and some will still do well if situated near a west facing window. Signs of plants lacking the amount of light they need include elongating of stems between the leaves (becoming leggy); leaves not growing to their full potential size; and yellowing discolouration of the plant. For the keen kitchen gardener, grow lights are available which take care of many of the issues caused by lack of light.
Most herbs enjoy the same temperatures as humans. So, if you aren’t feeling too hot or too cold, then it’s likely your herbs will be feeling the same! It’s worth remembering that temperatures next to a window will be more extreme during winter months, so make sure that leaves are not directly touching windows where there is a risk they may freeze. Another advantage to growing herbs indoors is that pots can be moved around the house to ensure they are in the best areas to suit their growth.
Watering indoors requires some thought. Make sure you have a suitable watering tray underneath your pot to ensure any excess liquid does not end up on your kitchen counter or windowsill. Clay pots can heat up in more extreme temperatures and therefore tend to dry out quicker.
If plants are in reasonably sized plastic containers, a quick and easy way to establish moisture levels within the pot is to simply pick them up. If they are heavy, then they most likely have enough water and if they are light, then watering them from underneath would be a good idea.
There are many more herbs which you can incorporate into your indoor herb garden in addition to the ones mentioned above, for example, sage, rosemary and marjoram as well as more adventurous additions such as tarragon and lemon verbena.
