Calibrachoa is native to warm regions and resists frost. In hardy zones, it is considered an annual flowering plant. Their leaves turn black and the plant dies in winter in such regions.

If you grow them in pots, you can move them to the warm greenhouses during cool weather to protect them. Once the weather warms up, you can return them to the garden. While this is a climatic condition, you should know other essential factors.

My Calibrachoa Has Brown Leaves

When the soil is damp, they experience root rot, the most common reason for their death. They prefer soaking and then drying and getting soaked again. Consistent dampness is not tolerable by these plants.

Watering it only when necessary and proper drainage arrangement can avoid these issues. Otherwise, their leaves give a dying appearance as they droop while turning brown. 

You can water it once a week generously to soak the soil. Let it dry out a little but not thoroughly, then water it again. Do not let it dry out completely. This watering style breaks the roots from dampness and replicates the native environmental conditions.

Underwatering can also kill calibrachoas. They usually suffer over watering as their needs are scarce, but they are sometimes forgotten for the same reason. Maintaining the proper moisture balance is key for these beautiful flowering plants to flourish without any issues.

They wilt and become lifeless if the water is not enough. When the weather condition changes, you should remember to water them accordingly. For instance, in arid conditions, you might need to water it twice a week. If the soil is too draining like sand, it might require watering more than once a week.

Calibrachoas hanging in baskets are more vulnerable to drought than the pots. They have high exposure to wind and do not have a lot of soil for moisture retainment.

Also, if you allow the potting soil to dry completely, the soil becomes hard-baked and does not allow any water through it. Instead, the water runs off the surface and flows down the drainage rather than into the soil.

To avoid this, you should water these plants slowly such that it soaks well into the soil. Check the plant’s soil up to finger depth; if it is dry, your plant is for sure suffering from drought. 

Keep similarly monitoring the soil throughout the week and provide proper moisture. This process also helps you determine the ideal watering period tailored to your plant conditions.

Factors That Keep The Soil Wet Around Calibrachoa 

Calibrachoas are pot-loving plants. Usually, pots and containers are equipped with saucers or trays. However, these drip trays and saucers do not allow easy escape of excess moisture leading to root rot.

Check if your pots have drainage holes at the bottom. Few decorative pots do not have holes at their base. Such pots are not suitable for growing calibrachoas as the water cannot drain as required.

It is a well-suited plant for hanging baskets as it does not need constant watering. However, check the baskets for plastic sheets or other liners that do not allow the water to drain. Again, it is crucial to let the water out to prevent root rot.

A common but important reason is overwatering. This plant cannot tolerate excess water. So do not overwater it like your other plants. Each plant has a different requirement.  

It is necessary to replicate its native environment’s typical moisture conditions. Once a week in normal condition and twice or thrice a week during the heatwave will suffice.

Frequently Asked Questions

When is it not possible to revive a calibrachoa?

If the plant stays in saturated soil for an extended period, it becomes impossible to revive it. As it is challenging to cure root rot, aiming to prevent it in the first place is the best way to save them. 

When you see the drooping leaves, you should check their condition. You should learn to identify if it is just stressed or root rotting. A drooping scenario usually indicates stress, and adjusting the watering routine and drainage will fix it.

Can I revive Calibrachoa with Yellow Leaves?

A plant that stops flowering, growing, and starts turning yellow signifies nutrient deficiency. Add fertilizers to bring it back to life. It is most common in plants growing in small pots.

You can fix it by adding all-purpose fertilizer of half strength. Avoid too much fertilizer as it burns the roots. Once things are right, it starts growing faster and recovers from its yellowness within 2 weeks.

How can I know if my calibrachoa is getting enough sun?

Calibrachoas love the sun. They need good sunlight. You can say they are getting enough sun by looking at their blooms. The flowers look unhealthy if there is not enough sunlight.

Even the overall plant growth is spindly and poor. Open areas, a warm climate, and 6 hours of sun are ideal. Try to place them in the sunniest area of your garden.
