So, your junipers will grow fast and strong easily. Other than that, there are other features to focus on. So, let’s head on with it- 

First off, the 16 important minerals make it easier for plants to grow well. So, the junipers will never face problems with their growth or health factor. 

As it’s liquid-based, you won’t require many complications with the application process. But, the drawback here is that it doesn’t leave nutrients for a long time. And, this creates a problem. But, how? 

Well, thing is- you’ll need to apply the product frequently. That’s all. After the application, the product continues to provide nutrients as it did before. But, the further application bothers many people who have a lot going on. 

Now, the juniper trees grow better in 16-4-8 or 12-4-8 fertilizer formulation. But, here, the product comes in 7-9-5 formulation only. Now, this could be a problem for some gardeners. But, the essential minerals will provide all the nutrients needed for the junipers.

3. Perfect Plants Bonsai Fertilizer Pellets

No products found.

Up next and in the top three, we have the Bonsai fertilizer pellets from the brand- Perfect Plants. If you’re tired of using liquid fertilizers then this product will bring a change. 

After all, the USP of this product is in the form of fertilizer. And, the best part about this form is that it’ll provide supply for over 5 years. We believe that’s a lot if you’re beginning to fertilize outdoor plants. 

Here, the product itself comes in a resealable bag. Also, the bag is lightweight and easy to carry around (if you intend to). 

Now, it’s perfect for the live bonsai trees. But, since we’re focusing on junipers here, it’ll work on that as well. The fertilizer pellets ensure that your juniper trees get all the nutrients it needs. So, no chance of hampering growth. 

As we’re on the topic of providing nutrients, there are a couple of things you’ll need to know. The fertilizers release a slower formula for boosting the health of the juniper trees. 

Since the fertilizer allows slow release of the nutrients, the juniper and bonsai trees can last for a long time. And, it’s not about juniper or bonsai trees. You can use these fertilizer pellets on different outdoor plants too. 

At times, people over-fertilize plants. As a result, different complex reactions take place. But, that won’t be the case as this fertilizer only focuses on the nutrients and will keep the juniper trees completely safe. 

Other than that, fertilizer pellets are better in many cases than liquid fertilizers. But, how? Well, the pellets release a slow nutrient formula. As a result, the plants get nutrients all year long and get benefits. 

In the end, the fertilizer pellets make it easier for nutrients to enter the plants. As a result, the plants grow thick and strong. Plus, the slow-release formula provides nutrients for a long time. 

4. Jobe’s 01661 Fertilizer Spikes

No products found.

Down to the last two. But let’s talk about the Fertilizer Spikes from Jobe. Similar to the previous product, this one also isn’t a liquid fertilizer. Here, the product is based on fertilizer spikes. So, let’s check it out in detail- 

The first thing to clear out, the fertilizer doesn’t have a liquid form. So, you’ll need to use fertilizer spikes. And, if you ask us, it’s a better tradeoff. But, how? 

Well, fertilizer spikes target directly the roots of the juniper trees. As a result, these spikes ensure that the roots are nourished beforehand. So, it’ll be a great health boost for the juniper trees. 

On the other hand, these are time-release fertilizers. So, they’re easy to use and contain no complications whatsoever. Speaking of usage, these fertilizers contain little to no mess or smells. So, you won’t really have to worry about these factors. 

Another helpful factor is that it doesn’t have wasteful runoff as well. So, you can proceed with the application process easier. And, if you’re wondering when to use these spikes then go for late fall and early spring. 

Similar to the previous product, this one has a slow-release formula. This means you won’t have to frequently use these spikes. And, the formula causes these fertilizer spikes to last around all the seasons. 

All you have to do is use them once or twice and wait out for the results. And, when you apply them to the roots, that’s when the junipers start growing well and get an overall health boost. 

Many questions how many spikes are needed for a single tree? Well, you’ll need 2 spikes for each tree. And, apply them 1-2 inches of the trunk’s diameter. 

To summarize, these fertilizer spikes ensure nutrients to the juniper trees. Here, they’ll ensure the nutrients from the roots. And, the slow-release formula ensures the presence of nutrients all year long. 

5. Schultz Liquid Plant Food

No products found.

Last fertilizer on our list- Schultz liquid plant food. And, yes, we’re back with liquid fertilizers again. The best thing about this fertilizer is that it’s excellent for transplanting and repotting. 

But, there are other features as well. So, let’s get on with it- 

Starting off, the fertilizer will feed your plants with nutrients every time you use it. Here, liquid food is easier to use as well. All you have to do is add 7 quarts of water with the fertilizer and it’s ready to be used. 

On top of this, the liquid fertilizer starts off straight away with the nutrients and helps the junipers grow well. In fact, it works on all kinds of outdoor and indoor plants. So, you’ll have your options. 

Speaking of options, the fertilizers can be used on vegetables and flowers as well. But, make sure you’re not going overboard with it. 

Now, junipers normally benefit from fertilizers having a 12-4-8 or 16-4-8 NPK ratio. But, here, the product comes with a 10-15-10 ratio. That said, you can still work with them. 

But, the imbalance in the ratio causes us to reduce a point or two from this product. With that said, it’s still a great fertilizer and will ensure a complete health boost to your juniper trees. 

As it’s a liquid product, you’ll need to mix it up with water before applying. Here, the manufacturers have added in a dropper with the product. So, you can measure the water amount and then add it to the juniper trees. 

To be precise, you’ll need only 7 drops of water per quart. After you apply the fertilizer, it’ll promote new growth straight away. And, it’ll be quite beneficial for the indoor plants. 

Fertilizer for Junipers – Buying Guide

best fertilizer for junipers

Even though we’re done with the review section, we’re not done with the article. If you’ve made it to this point then you’ll know about our best 5. But, how do you choose one out of the 5? 

Plus, reading this much information at a stretch isn’t enough to come to a decision. As a matter of fact, it makes making a decision even harder. Hence, to make things easier and simple, we’ve brought out this guide. 

Here, all of the important buying considerations and factors are provided clearly. So, you won’t miss out on anything. Sounds promising? Let’s go-  

Does NPK Ratio Matter? 

Yes, the NPK ratio does matter. That’s why the entire formula for the juniper trees starts at 16-4-8 or 12-4-8. And, the fertilizers providing these formulations provide the best results. 

That said, some fertilizers shown in our list vary from this formulation. But, they still provide essential minerals important for the junipers. So, you’ll need to check whether they’re compatible with your trees or not. 

Otherwise, you won’t get the benefits and results that you desire. 

Is a Slow-Release Formula Important? 

Honestly, slow-release formula fertilizers have different types of benefits. Here, they provide nutrients all year long. But, some complain that different fertilizers take a bit of time to provide the expected results. 

In the end, it comes down to your preference. So, if you prefer that your plants get nutrition throughout the season then invest in one. 

This means you won’t even have to frequently apply fertilizers over your trees. And, that saves you a lot of time and hassle. 

Liquid Fertilizer, Fertilizer Pellets, Fertilizer Spikes: What’s Better? 

When compared to the three types of fertilizers. They function differently and have different benefits. 

Honestly, the easiest to apply out of the three are the liquid fertilizers. Even though you’ll need to mix them with water, they won’t be hard to apply. 

Also, just spray them over the plants. That’ll do the trick easily. On the other hand, fertilizer pellets come in lightweight bags. And, they can be applied from that bag. 

Here, you don’t need to mix them and that saves some time. Whereas, fertilizer spikes need to be dug in the ground. So, when it comes to harder soils, that can be hard. 

But, spikes are durable as well. That said, they are the hardest to apply amongst the three, in our opinion. 

Now, when it comes to liquid fertilizer, they don’t have a slow release of nutrients. This means you’ll need to provide them on a frequent basis. But, when it comes to the fertilizer pellets and spikes, you won’t require using them frequently. And, why? 

Well, they release a slow-release of nutrients to your plants. So, you don’t need to apply them again and again as your plants will get the nutrients. 

In the end, it all comes to your preference what you’ll need for the junipers. In our opinion, if you don’t have problems with frequent fertilizing, choose the liquid ones. They’re easy to apply and have no complications. 

Application Factor

Even though we’ve talked about application for quite some time in the previous factor, there are still some things to be said. 

First off, what type of fertilizer have you chosen? 

As there are different fertilizers on the market, you’ll have to choose one. When you’re done choosing, then proceed with the application process. 

Well, they’re easy to apply. And, if you’re working with a liquid one then you’ll have an easy time. Just mix it up with water and start using them on a frequent basis. 

But, if you’re a beginner and new to gardening, go for the liquid ones. They’ll be easier to deal with and have proper instructions. Plus, they are the most common ones in the market. So, your life will be easy. 


Well, above all, budget matters. Even though gardening could be a hobby for many. But, you don’t want to spend a lot on your hobby, right? 

So, it’s important that you’ll set your budget and then start the work accordingly. But, I don’t think that buying a premium product means a better result. 

We’ve already shown in the list that medium-range products bring better benefits for the junipers. So, you’ll need to choose according to your budget.
