We’ve all been there… bought a new plant baby, lovingly watered and nurtured it, gave it the perfect spot,… then cried as it withered away and died despite all your hard work. Been there, done that. So let’s just get this out in the open. Not all plants like being indoors. Some like more sun, others like the temperature fluctuations that come with the outdoors, others just need better air circulation… So let me help you stay away from those sad plant deaths and tell you which indoor herbs are the hardest to grow indoors.
*Note: These herbs can still be successfully grown indoors, but they will have more indoor plant deaths than their easy-to-grow herb counterparts. If one of your favorite herbs is on this list, you might just need to do some extra research before purchasing one of these plants for growing indoors.*
Worst Indoor Herbs #1: Basil
Basil is one of those herbs that everyone has because it’s so useful, but that dies in a lot of people’s care. This is because basil plants need a lot of sun to grow well, and a lot of water to keep it happy in the sun. When caring for my basil plant, I noticed that I had to water it at least once EVERY DAY during the summer to keep it happy. And with it being in the brightest spot in the house, it STILL produced small leaves. So that’s why it’s on my list of worst herbs to grow indoors… it needs a LOT of attention and is very difficult to produce those large, tasty leaves that are so much easier to grow outdoors.
Quick Tip: If you still want to grow basil indoors, try out one of the smaller-leaf basil such as a Thai basil. This will be easier to care for and will grow better indoors.
Worst Indoor Herbs #2: Cilantro
Cilantro makes the list of worst herbs to grow because it also needs a LOT of sunlight to grow. Most indoor cilantro plants that I see all have small leaves and are stretched because they aren’t getting enough sunlight. In order for cilantro plants to produce well, they need to have lots of sun and lots of space, which makes them one of the worst herbs to grow indoors.
Quick Tip: If you still want to grow cilantro indoors, then grow them in large flats and put in plenty of seeds. Then start another tray 4-6 weeks later, and maybe another tray after that. Then make sure that your cilantro has a dedicated grow light. This will help you feel okay about over-harvesting since you will have other trays growing. You will also be able to harvest each tray at once and before it begins to bolt (aka flower). This method of having different trays at different development stages (and each with their own light) is one way to successfully grow cilantro indoors.
Worst Indoor Herbs #3: Italian Parsley
Just like cilantro, parsley makes this list of worst herbs to grow indoors based on the amount of light that it needs to produce large, harvest-worthy leaves. Indoors, parsley needs to be placed in a sunny window, and will need to be turned every other time that you water it to ensure even growth. Even with this, it might still not produce large enough leaves. Then it will need a dedicated plant light to stimulate large leaf growth.
If you want to grow parsley indoors, then I would suggest you use a curly leaf parsley (as opposed to flat-leaf parsley, such as the common Italian parsley). Curly leaf parsley is usually a bit easier to grow and will give you a better harvest than the flat-leaf parsley.
Worst Indoor Herbs #4: Dill
Dill is actually pretty easy to grow, however, this plant gets huge! Unless you’ve got a spare 3-4 feet to give this herb, then you won’t be able to keep it in your windowsill herb garden!
To grow dill indoors, try a fern-leaf variety, which will only grow to about 1.5-2 feet in height. You’ll still need to give it some space, but at least this smaller size is more realistic for an indoor plant.
Worst Indoor Herbs #5: Fennel
Fennel is one of the worst herbs to grow indoors because, like dill, it is also huge! Most fennel plants can reach up to 6 feet in height! I don’t know about you, but I DEFINITELY don’t have this type of space in my home! So while you can grow it from a small plant indoors, you’ll eventually want to bring it outdoors. This will allow the plant to have enough space to grow its large, onion-like bulbs (that are also edible!).
There aren’t really any options to grow this herb indoors, but if you want to overwinter it, you can grow it in large, deep pots outdoors during the summer. Then in the fall, cut it back to a few feet in height and bring it indoors. This way, it can continue to stay warm and grow throughout the winter. You can continue to harvest the leaves all winter long as it grows, and then simply move it back out the following spring before it really begins its spring-time growth.
