Welcome to this post about what temperature dill grows in. Dill is one of the hardiest plants or herbs you can grow at home. Probably one of the reasons it’s a lot more common in northern countries than in northern states. It can actually handle temperature drops of as low as 25 degrees, or -4 celsius.

It’s hard finding any other culinary herb that manages the same type of drops. But what is the optimal place to grow dill in. Follow along and we will go over all the best places to keep it but also what makes it grow really fast.

If you are interested in reading a complete guide that covers when the best time is to plant dill then we have written an article dedicated to that specific topic. You can find it here, When To Plant Dill In.

What Temperature Do Dill Grow In

We sort of hinted at it already in the beginning of this article about the temperate us that dill can handle to grow in. 25 degrees is sort of the lowest point. Since this is below freezing it won’t do much good for the herb anyway at this level. But what is the ideal temperature to grow dill in?

We believe that this is around 70 degrees and so do a lot of other people. We have seen the best result at this temperature and it seems to thrive the best. Even though you might cut it back a bit it won’t slow down the growth that much. Even after a few weeks it grew back significantly.

Reaching the temperatures we talked about above is probably only really doable during the summer and maybe spring and autumn a little bit depending on where you live. You should know that even though it’s pretty warm at 70 degrees for the dill plant, it doesn’t really like going above this point.

Then it will have a detrimental effect on the plant and it can wilt very quickly. A lot of people like to grow dill in the largest tunnels that maintain heat very well. The downside of this is having them be too warm. So you need to be worried about your dill plant.

If you want to read even further about how low temperature dill can manage we have written an entire article dedicated to that. You can find it here, How Cold Can Dill Tolerate.

Now we’ll talk about some of the measures you can take when the temperatures reach either end of the spectrum we have talked about. Once it starts to freeze outside then the best thing to do for the plant is to cut it down completely. Dill is a perennial herb that will come back the next year just as strong. We recommend that you do this to maximize the harvest you get from the herb and nothing is left to waste.

Does Dill Like Hot Weather?

It does like hot weather but when it goes above 90 – 95 degrees it will start to struggle. The stems will hang more and more. What should you do when it gets really hot then? We feel like the best thing to do is not to cut it significantly. It can stress out the plant even more as it tries to manage the heat too. So just make sure you water it correctly. That includes never letting the soil dry out completely. Instead it should be kept wet or moist at all times.

I want to reiterate again on the question we had. What the temperature is that dill can grow in. The lowest point is around 25 degrees, but don’t expect much growth at this level. The best conditions for growing dill is at 70 degrees. Here it can grow quickly and steadily without much effort.

Knowing when dill can go outside if its been growing in a pot can be a hard decision. In this article we give help knowing when the best time is. Find it here, When Can Dill Go Outside?
