If you’re looking for a vibrant splash of bright blue in your garden, you can’t go wrong with a California lilac. There are around fifty shrub species in the Ceanothus genus.

Why are my California lilac leaves turning yellow?
Yellowing leaves are arguably the most prevalent issue in the gardening world. Overwatering or a lack of nutrients are the 2 main causes of this issue.
Reduce your watering frequency when you fear your plants are being overwatered, and follow these steps to determine whether they may be lacking in nutrients:
Here are some indicators of yellowing on the Ceanothus spp. brought on by its numerous flaws:
- Yellow patches between leaf veins on elder leaves are the first sign of magnesium shortage. Veins continue to be green while the leaf’s core turns yellow. The leaf’s edges yellow last.
- Iron deficiency also shows as yellowing between leaf veins, but it hits young leaves on plant tops and branch tips first.
- Sulfur shortage first affects the youngest leaves, turning them entirely yellow.
- Leaf edges turning bright yellow but inside leaf remaining green are signs of potassium insufficiency. The symptoms first appear on older leaves, and the leaf edges quickly become dark.
- A broad yellowing indicates a nitrogen deficiency. Yellowing starts with older, inner leaves. Yellowing spreads as it advances, eventually touching new leaves as well.
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 lilac sunburned?
It is quite easy to find out if your California lilac (Ceanothus spp.) has been burned by the sun. Just like on us, your plant will change color in this case, it will start to turn yellow or white.
As we saw above, the leaves of your California lilac can also change color if it receives too much water or insufficient light.
The bottom of the yellow leaves with a shaded area closer to the base can be examined to determine if they have been sunburned. If this part remains greener, the yellow leaf is most likely sunburned and not something else.
Why are my California lilac leaves turning brown?
Most of the time, leaves of a California lilac that turn brown is a sign that your plant has been sunburned, it has probably been exposed to too much direct sunlight. Don’t panic, your plant probably won’t die from this, but its growth will take a hit.
Should I leave my Ceanothus spp. in direct sunlight?
No! If your Ceanothus spp. (or California lilac) has the symptoms described above, don’t leave it in direct sunlight, that’s the reason why your California lilac is in such a state!
As explained in the paragraph above, the solution is simple, just place your California lilac in a place where the light does not reach it directly, in this way and with a correct watering, your plant should resume its life rather quickly.
Why are my Ceanothus spp. leaves drooping or wilting ?
This typically occurs when your Ceanothus spp. gets dehydrated. Large plants are more at risk since they naturally require more water than smaller plants.
You may quickly determine if your Ceanothus spp. plant needs water by under-weighing its pot; if it seems light, the soil and roots are probably fairly dry and require water.
If the soil in the container is completely dry, you must first moisten it to guarantee that your plant’s roots absorb the benefits of the water. One common mistake is to drown the California lilac right away after a dry time because you think it needs a lot of water.
This is the case, but giving too much water at once is the best way to finish it off, you should actually water the soil normally, resuming a quiet watering rhythm.
Caring Tips for Ceanothus spp.
Water is necessary for your plant to live, but timing and amount of watering must be balanced. Overwatering could have disastrous effects on your own name, as we already mentioned.
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
Maintaining a consistent temperature for your Ceanothus spp. is also a good idea, especially if it is kept indoors. At GreenShack, we typically advise reserving a temperature between 65 and 85 degrees F. Of course, avoid positioning your Ceanothus spp. close to air conditioners, radiators, or other sources of hot or cold air.
Keep your California lilac Dust-Free
This one relates to indoor plants. Just like your furniture, dust collects on the leaves of your indoor plants. The issue is that this can block the photosynthesis process from starting, which would cause the plants to gradually lose their color.
This would also make the pests happy, a real descent into hell for your California lilac.
Take a microfiber cloth and gently massage the plant’s leaves to get rid of the dust. Use a damp cloth to make dust removal easier, but avoid using corrosive materials like rubbing alcohol!
Keep drainage in mind
If you tend to overwater, you need to pay attention to your drainage, and we advise choosing a saucer and a pot with drainage holes if they are not already there.
If your pots don’t already have holes in them, you can add volcanic rocks (or any other pebbles with holes) to the bottom of your pot in the meantime. This will assist in creating a channel and keep the water from pooling there for an extended period of time, protecting the roots from decay.
