If you are looking at growing rosemary then there are various things that you should really pay attention to that will help to keep your plant alive and to then thrive under the correct conditions. Now, it is generally accepted that growing rosemary indoors is not particularly complex making it a perfect plant for those that are new to this but that is not to say that things cannot go wrong. They do and it is how you deal with it that is key.
- 1. Understand what can kill your rosemary.
The first tip is to just make sure that you understand what is capable of killing your rosemary so you can avoid those situations in the first place. In general, there are four things to be aware of that will have a profound impact on the way in which your plant grows. If your rosemary has a lack of sunlight, then it cannot convert that into enough energy to grow. Also, being erratic with your watering will also make a difference because rosemary is very specific in its needs. Finally, both powdery mildew and pests can also kill the plant so the correct course of action has to be taken to avoid this.
- 2. Understand its native climate.
This is also important in that you need to be aware of its native climate so you can then replicate it to the best of your ability. It stands to reason that it will thrive in these conditions, which are
- 3. Make sure you have the correct pot.
Getting the correct pot is important for your rosemary to survive. It really should be a minimum of eight inches deep to accommodate it and you should also really avoid a glazed pot. This allows air to get to the roots so your plant is not going to become waterlogged.
- 4. Make sure you have the correct soil.
Rosemary plants require well drained soil for them to survive. This means you cannot use normal gardening soil or anything with peat in it. Instead, add sand, perlite, or vermiculite to help with the drainage.
- 5. Make sure there is the correct drainage.
Sticking with the idea of the correct soil we also have to mention the drainage. This is going to involve you making sure that there are drainage holes in the base of the pot to allow any excess water to drain out. Also, you need to keep an eye on your watering as this fits in with the drainage and soil requirements.
- 6. Give it a lot of light.
Rosemary is a plant that loves full sun, but as you are growing it indoors then you need to do something about this or else the plant is going to struggle and probably die. Look at your windows and understand which ones get the most light for the longest part of the day and that is where it should be situated.
- 7. Think about using LED grow lights to help you out.
Another idea is to supplement the natural light that you are giving the plant with powerful artificial lights and the best option when it comes to that are LED grow lights. They are going to provide the rosemary plant with the full spectrum of light that it is looking for and, at the same time, give it the correct light to enhance its ability to grow.
- 8. Be aware of how to water it.
Here is a problem, it is very common for rosemary plants that are being grown indoors to either be watered too much or not watered enough and neither of them are going to then contribute to a healthy plant. In all honesty, you should only look at watering the plant when the top two inches of soil are dry and at that just makes sure that it is wet and not saturated or else the roots are going to struggle with the moisture.
- 9. Focus on the circulation of air.
When it comes to rosemary then it needs air circulating around it as this is going to reduce the possibility of it picking up mildew that is caused by stagnant air. This is something that rosemary is prone to so the fact that just putting something such as a fan on the plant can then resolve it is a major bonus as mildew is really going to set the plant back with its development.
- 10. Be aware of fertilizer.
Rosemary is not a heavy feeder and that does mean that there is no real need for you to go ahead and use fertilizer on a regular basis. Instead, it is quite light when it comes to all of this and if you add in some slow release fertilizer when you plant it then this is going to last it for quite a substantial period of time. However, do make sure that you use a balanced fertilizer when you do as this will help it to grow into a strong and healthy mature plant. Make sure that it has nitrogen, potassium and phosphorus so that the plant then thrives.
- 11. Be aware of the need for matching the pot to the size of the plant.
This can certainly be something that is overlooked by people, but there is a very real need for you to look at matching up the size of the pot with the size of the plant so that there is no real problem between the two. This is because a rosemary plant is going to have quite an extensive root system and if it becomes pot bound then you can have all kinds of problems. In general, if a plant is going to be eight inches high then you need a pot eight inches deep so it is easier to understand than you were perhaps expecting.
- 12. Realize that you need to change the soil.
The one thing that you must do with your rosemary plant is to change the soil on a yearly basis. The reason for this is very easy to understand as it is because you have exhausted all of the important nutrients and minerals that are in the soil that will help the plant and as a result there is going to be real difficulty in getting it to sprout in the next growing seasons. Add in fresh stuff and the plant will reward you as it gets that all important boost from the new levels of nutrients that it has previously been missing out on.
- 13. Consider root pruning.
Now this is something that will often scare people, but the idea of root pruning is something that can certainly really help your plant rather than hinder it. You see, if the roots are coming out of the bottom of the pot then you are able to trim them so that the rosemary can stay in its own pot. This is not something that is going to harm the plant and it is still going to thrive under those conditions. Take it out of the pot, trim off around 2 inches of roots and then put it back. Just remember to shake some of the soil off in order to free up the roots so you do not then hack away at them as this can lead to problems with the plant.
- 14. Consider using just a normal household pesticide.
Rosemary plants can actually be affected by pests and the best way to go ahead and deal with them is to use just a normal household pesticide. This is not going to be anywhere near as toxic as the other varieties that are for outdoor use so there is no need to worry about how it is going to affect your health. Also, various household sprays have been shown to work and that is the most important thing of all.
- 15. Alternatively, look for organic pesticides.
As we just said, you do not want to go ahead and cover your rosemary with things that are too toxic and for that very reason you should consider organic pesticides as there is no doubt that they are a lot safer to use than the other potential methods. However, we do recommend that you spend time finding a quality one to use or even consider trying to make your own as it is going to be easier than you think. The most important thing of all is that it works.
So those are important things for you to keep in mind when it comes to making sure that your rosemary plant is not only kept alive but is able to just keep on growing. As you can see, some basic knowledge is going to take you a long way although you do still have to be careful with what you do at all times.
