Why Should I fertilize My Juniper?

The most common reason for fertilizing juniper is to make it healthy for the upcoming years. In the first few years, you need to fertilize it every 6 months as a result they get nutrients which help it to establish its roots. Juniper may reach new heights and get all the branching just because the owner has given it an initial phase nutrient rich fertilizer.

Junipers are evergreen so in fall they may lose color to turn dark and after that a new season will start and that time your tree again needs fertilizer for its proper nutrition. Feeding them well will result in a more healthy and large tree.

Juniper fertilizer spikes are one of the easiest methods to provide adequate nutrients to the shrubs and trees. They are directly pushed into the ground and after regular watering, fertilizer spikes keep distributing nutrients to the soil, mainly the root of your juniper. This helps them over the year to get nourished without much work. It is a simple way which avoids the extra work done when applying liquid fertilizer. Slow release fertilizer generally takes time to make it to the ground, also they don’t have sufficient nutrients for a juniper otherwise you keep on pouring fertilizer to make them happy. These fertilizer spikes are applied and forgotten methods where spikes are dug into the ground using a hammer or drill then wait for the magic in the coming year. Do not forget to always pour water in hot summers.

How to Fertilize Juniper?

Generally a juniper requires light feeding and this will benefit it for the whole year. Fertilizing the juniper with slow release fertilizer in early spring or after 60 days of frost with a solution of N-P-K as 16-4-8 or 14-4-8.  You can also fertilize it with iron based plant food which encourages greening in junipers.

Newer leaves may not last in winters and die back. So better if you care for the plant after the first frost. Some people also use balanced fertilizer of 10-10-10 or 20-20-20 by taking 2 tablespoons per gallon of water. You need to spread the fertilizer around the plant. I advise not to put any fertilizer directly on the main trunk or stem. 

If you live in an area with a lot of rainfall then you should make sure the rain does not wash away the slow-release fertilizer. Apply that on sunny days and not on rainy days. There will be one or two days you get when there is very less rainfall so that day you can easily feed your tree.

Also one of the benefits of juniper is that it will adjust to overwatering which is the main issue in every plant nowadays. so other than that keep them healthy on sunny days and give them proper water. Do not let the foliage turn to any color to indicate about its watering issue, timely give water to your juniper.

Should I fertilize juniper with already nutrient-rich Soil?

It depends on whether your juniper needs fertilizer or not. If you have added fresh nutrient rich soil then it isn’t required until the next spring. If you notice less green foliage then it can be added in early spring or late winters. 

Nutrient rich soil has High N-P-K value which is proper for any tree. If you still give it more fertilizer than due to over-fertilizing your juniper may die or show signs like leaf browning or black. Some of the leaves may droopy or die back after few weeks. So do not give it if it already has the fertilizer.

Juniper Fertilizer Bonsai

A juniper bonsai is smaller in size but requires a good amount of fertilizer that can be given using a slow release fertilizer that slowly reaches to the soil and rooting system so your juniper bonsai can be healthy in the growing season. I already advised everyone that using a low nitrogen & high potassium, phosphorus fertilizer will enhance the branching and size of the plant. To make your bonsai juniper more healthy and green you need a high nitrogen fertilizer. There are also iron based plant foods used in shrubs that makes the foliage green and healthy.

Juniper fertilizer ratio

Juniper fertilizer ratio is either 15-15-15 or 20-20-20 for large size shrubs. You can also use high nitrogen ratio fertilizer in juniper such as 16-4-8 and 12-4-8. For overall growth balanced N-P-K ratio is best and for fruiting and foliage growth you can always select the nitrogen based fertilizers. They enjoys fertilizing in in early spring or at the end of winters. This is because it’s the growing season for juniper after spring. It’s as per instruction you can apply the fertilizer but do not over-fertilize your shrubs.

How do you increase juniper growth?

It is possible to promote juniper growth in a number of methods, including as by fertilisation, pruning, and appropriate watering. Making ensuring the plant gets adequate sunshine is one key aspect of juniper growth. Junipers should not be overwatered and should be planted in soil that drains properly. Regular pruning of junipers, which removes dead or damaged branches and improves air circulation, may also aid in promoting growth. A balanced fertilizer applied to junipers in the spring may also provide the nutrients required for strong growth.

Should you fertilize junipers in the fall?

In general, fertilizing junipers in the fall is not advised. By stimulating new growth in the fall, fertilizing increases the likelihood that it won’t have time to harden off before the winter, leaving the plant vulnerable to harm from freezing temperatures. As new growth starts in the spring, this is the best time to fertilize junipers because this is when the plant needs nutrients to support strong growth.

Is Miracle Grow good for junipers?

Popular fertilizer Miracle-Gro may be applied to a variety of plants, including junipers. However, it’s crucial to adhere to the manufacturer’s recommendations and use the right quantity of fertilizer for the plant’s size. The effects of overfertilization include root burn and other issues. Additionally, a balanced fertilizer made especially for evergreen plants should be used rather than one made for flowers or vegetables.

How do you keep junipers healthy?

The right growth conditions must be provided for junipers to remain healthy. Junipers need full sun to some shade and appreciate well-draining soil. They should get regular, thorough irrigation, with brief periods of soil drying in between. Regular pruning of junipers, which removes dead or diseased branches and improves air circulation, may also help maintain them healthy. Keeping the plant healthy and stress-free will help to avoid pests and illnesses. It is crucial to deal with issues as soon as they appear to stop them from spreading to other plants.

Rejuvenating junipers

Junipers may be revived by shearing or pruning back the plant to encourage new growth and removing any dead or damaged branches. When new growth is starting in the spring or early summer, this process works best. It’s crucial to avoid damaging the plant by taking out an excessive amount of it all at once. Instead, only take out a maximum of one-third of the plant at a time, and then wait for new growth to start before pruning once more. Rejuvenation pruning may encourage healthy growth while restoring the plant’s structure and vitality.

Blue Point juniper fertilizer

A well-liked juniper type known for its rich, blue-green leaves and upright growth habit is called Blue Point juniper. It is advised to fertilize Blue Point juniper in the spring when new growth is starting using a balanced fertilizer made for evergreen plants. Avoid overfertilizing as this might result in root burn and other issues. For optimum growth, Blue Point juniper should also be planted in well-draining soil and given full sun to moderate shade.

Is Holly-tone good for junipers?

Holly-tone is a kind of organic fertilizer made for plants that like acid, such azaleas, rhododendrons, and holly. Juniper plants can grow in somewhat acidic soil, but they don’t need as much acidity as these other plants need. Holly-tone may not be the ideal fertilizer for junipers as a result. Instead, it is advised to apply a balanced fertilizer made especially for evergreen plants. Additionally, it’s critical to take the soil pH and nutrient requirements of the plant into account when selecting a fertilizer for junipers.

Liquid fertilizer for juniper

For junipers, liquid fertilizers may be a practical and efficient source of nutrients. When using liquid fertilizers, the soil around the plant is usually treated by mixing the fertilizer with water. It’s crucial to use a balanced fertilizer made especially for evergreen plants when picking a liquid fertilizer for junipers. Additionally, it’s critical to adhere to the application rates and schedule recommended by the manufacturer because excessive fertilization can result in root burn and other issues. Additionally, liquid fertilizers may be a wise choice for junipers grown in containers as they can give the plant an immediate supply of nutrients.

Creeping Juniper fertilizer

Creeping Juniper fertilizer

Creeping juniper fertilizer wants slow release fertilizer for their growth. Use a 10-10-10 or 20-20-20 ratio fertilizer for creeping juniper ground cover. It will surely boost the overall growth including foliage, stem, and branches of juniper. Instructions are you need to dilute the solution for example two tablespoons of 20-20-20 fertilizer per gallon water can work for its growth and you can directly pour it in the shrub.  

Spartan Juniper fertilizer

Spartan Juniper fertilizers are not fond of soil nutrition but yes they require balanced fertilizer such as 15-15-15 or 20-20-20 to keep its foliage healthy and shiny. They also work very well for most fertilizer specially designed for shrubs. For better growth and enhanced branching you should be using that fertilizer every year. Slow-release plant food can also do wonders for spartan juniper as for people who want to feed the shrub once per month and forget it and the fertilizer gets absorbed into the soil making it more nutrient rich. 

Not only this, but you can try organic fertilizer using the kitchen waste which also makes one of the safest and pure kinds of fertilizer. I use this kitchen waste to include vegetables and fruit peels that are dropped in water for many days and poured into the soil. Or this waste can be dug and dropped under the soil for a month or two and the soil made out of it is full of nutrients.

Moonglow Juniper fertilizer

Moonglow juniper fertilizer is 10-10-10 or 15-15-15 N-P-K ratio. Moonglow are bigger pyramidal junipers so they require good feeding in early spring or in late winters. The foliage is silver blue in color and are most attractives juniper trees that have compact branching. They are perfect for any landscapes with its conical pyramid shape.

Juniper nana fertilizer

Juniper nana fertilizer requires 10-10-10 balanced fertilizer. Although Nana Juniper are not into heavy feeding but for their foliage health and branching they want to get nutrition from the plant food. You can also use high nitrogen based fertilizer if you feel your plant is not growing up to the mark with less foliage. Always fertilize them in spring or in late winters. This is the best time for them to get plant food so they are prepared to grow more in their growing season.

These trees can be as big as 130 feet or as small as 5 inches shrubs. It has 60-67 species of coniferous tree and shrubs. They are hardy to USDA zone 7 to 10 and can tolerate drought conditions.

Final Thoughts

Our junipers are light feeders but still they want fertilizer for their new season growth. I have listed all the fertilizer and you can use it as per your need. If you want to use it for the next spring then slow release or balanced fertilizer will work best. And for those who only want the color to get more green in those juniper leaves then use iron fertilizer given in the article.
