NOTE: California juniper may be referred to as Juniperus californica in this article, in fact, those are the same plants, Juniperus californica is the botanical name for California juniper.
The tough California juniper is a small tree or shrub that grows well in gardens that experience dry heat. It’s perfect for xeriscape spaces where water is in short supply or needs to be conserved.
Why does my Juniperus californica roots have rot?
Root rot on your California juniper (Juniperus californica) can be fatal if not treated with care. For this reason, we strongly recommend that you follow our guide to keep your plant alive if the symptoms occur: Root soft and blackened.
Why does my California juniper have gray mold spots?
A particular fungus known as gray mold spots spreads quickly and frequently damages flowers. This fungus is probably to blame if you see any brown (or gray) spots. If you disregard these warning signs, your plant could die.
When you understand the root of the issue, the solution makes perfect sense. The majority of the time, it is caused by the Juniperus californica being overwatered. We urge you to cut off the infected roots and leaves, remove the affected sections of the plant, and then repot your plant in a fresh container with sterile potting soil.
Why does my California juniper have leaf spots?
We provide you with all the information you need to identify and save your plants if they display signs like leaves that suddenly change color or wilt/droop. This sort of sickness is one of the most aggravating for California juniper owners.
Why are my California juniper leaves turning yellow?
This is probably the most common problem in the gardening world, yellowing leaves. There are 2 main reasons for this phenomenon, overwatering, or a lack of nutrients.
When it’s overwatering, simply reduce your watering frequency, and if you think it’s a nutrient deficiency, here’s how to check it:
Each deficiency produces a different yellowing on the Juniperus californica in question, here’s how to spot them:
- The first symptom of a magnesium deficiency is yellow patches between leaf veins on elder leaves. The leaf’s core turns yellow while the veins stay green. The edges of the leaf yellow last.
- Yellowing between leaf veins is another sign of iron shortage, but young leaves on plant tops and branch tips are initially affected.
- The newest leaves are first affected by sulfur deficiency, rendering them completely yellow.
- Insufficient potassium causes the leaf edges to turn brilliant yellow while the interior of the leaf stays green. Older leaves show the symptoms initially, and the leaf edges quickly darken.
- Nitrogen deficiency shows up as a general yellowing. Older, inner leaves turn yellow first. As it progresses, yellowing moves outward, eventually reaching young leaves, too.
According to the symptoms mentioned above, you just have to act accordingly. You can reduce your watering frequency, or fix a deficiency in Potassium, or Nitrogen, for that, you just have to buy a special soil for your deficiency, a consultant in a gardening store will know perfectly well how to inform you.
Is my California juniper sunburned?
You can easily tell if your California juniper (your Juniperus californica) has a sunburn. In this case, your plant will change color, starting to turn yellow or white, much like it does on us.
As we saw above, the leaves of your California juniper can also change color if it receives too much water or insufficient light.
To find out if the yellow leaves have been sunburned, look at the part of the bottom that is tinted closer to the base. The yellow leaf is probably burnt and not something else if this portion stays greener.
Why are my California juniper leaves turning brown?
A plant’s browning leaves are typically a symptom that it has been sunburned and has been exposed to excessive amounts of direct sunlight. Don’t worry; your plant probably won’t perish as a result, but its growth will be negatively impacted.
Should I leave my Juniperus californica in direct sunlight?
No! Don’t leave your Juniperus californica (or California juniper) in the sun if it displays the symptoms mentioned above; that’s why it’s in such a bad situation.
The remedy, as said in the paragraph above, is simple: just move your plant’s California juniper out of direct sunlight. Your plant should swiftly re-grow with this strategy and appropriate watering.
Why are my Juniperus californica leaves drooping or wilting ?
This typically occurs when your Juniperus californica gets dehydrated. Large plants are more at risk since they naturally require more water than smaller plants.
You may quickly determine if your Juniperus californica plant needs water by under-weighing its pot; if it seems light, the soil and roots are probably fairly dry and require water.
In order to ensure that the roots of your plant receive the water’s benefits, you must first moisten the soil in the container if it is absolutely dry. One common error is to immediately drown the California juniper after a dry period in the belief that it requires a lot of water.
This is true, but the easiest way to end it is to give too much water at once. Instead, you should water the soil properly, returning to a peaceful watering rhythm.
Caring Tips for Juniperus californica
Your plant needs water to survive, but it’s crucial to balance the amount and timing of watering. As we previously mentioned, overwatering could be catastrophic for your Juniperus californica.
You can tell if your plant needs water by touching the soil; if it still feels damp, it’s usually preferable to wait a few more days.
Always keep temperatures stable
It is also a good idea to keep your Juniperus californica at a stable temperature (especially if it is kept indoors!). At GreenShack, we generally recommend staying in the 65 and 85 degrees F range. Of course, do not place your Juniperus californica near a source of hot (or cold) air such as A/C units, radiators or the like.
Keep your California juniper Dust-Free
This one concerns indoor plants, just like on your furniture, dust is also deposited on the leaves of your indoor plants, the problem is that it can prevent them from receiving the necessary light, this would slow down (or even stop) the photosynthesis process, and eventually, they would lose their colors.
For your California juniper, this would be a true descent into hell, and it would also appease the pests.
To remove the dust from the leaves of your plant, take a microfiber cloth and gently rub the leaves. You can wet the cloth to make it easier to remove the dust, but never use corrosive products (such as rubbing alcohol!)
Keep drainage in mind
If you have a tendency to overwater, you should be mindful of your drainage, and if they don’t already have them, we suggest selecting a saucer and a pot with drainage holes.
You can add volcanic rocks (or any other pebbles with holes) to the bottom of your pot in the interim if your pots don’t already have holes in them. This will help to form a channel so that the water doesn’t pool there for too long (preventing the rot of the roots!).
