Alluaudia ascendens Care Requirements

It is vital for you to care for Alluaudia ascendens so that you can maintain the right conditions in which it can thrive and be healthy. You can go through some of these conditions below.

Light

You should ensure that you provide full sunlight to your Alluaudia ascendens plant. This involves 6-8 hours of sunlight on a daily basis, preferably in the morning. You should also provide sufficient shade to this plant in the afternoon, especially if it gets quite hot where you live.

To ensure this, you can either place your pot outdoors or on a balcony or windowsill. If you are growing it indoors, make sure you opt for growing lights.

Watering

Regular watering is essential for the Alluaudia ascendens plant. However, since it is a succulent, it can store water to last for a while, which is why you should wait for the soil to become completely dry before you try to water it again. When you do water it, you should sufficiently soak the soil.

Using a pot with a drainage hole can help ensure that the excess water runs out and does not end up leading to root rot.

Soil

The soil that you use for your Alluaudia ascendens must be loose and coarse so that it can drain out the excess water properly. You can make use of a good succulent mix from the store or nursery or you can add some peat and perlite to your soil mix.

The loose nature of the soil can also help the air circulate effortlessly, making it easier for the roots to breathe and grow.

Fertilizing

Generally, fertilizing might not be necessary since Alluaudia ascendens should be able to glean the essential nutrients from the soil. However, if your plant does not seem to be growing as it should, you can add a balanced fertilizer to the soil once in the growing season.

However, make sure you dilute this fertilizer to around ¼ of its usual concentration. Even if the fertilizer label states otherwise, you should dilute it to suit this plant in particular.

Climate

This plant tends to thrive in warmer climates but is usually hardy up to USDA zones 9b-11b or around 0℃ or 32℉. However, this plant does not like frost and can end up withering and dying if exposed to it, so if your winters are quite harsh, it can be best for you to bring the plant indoors.

Ideally, you should not water the plant in the months of winter, since this is when it becomes dormant and loses its leaves.

Pests and Diseases

Typically, you will not need to worry too much about pests gathering on and harming your plant. However, you should always observe your plant properly to ensure that there are no scales, bugs or other such insects. If there are, you should use an insecticide or some dish soap to get rid of them.

Root rot is a common disease that might affect this plant, so you should try to prevent it with careful watering.

Pruning

Alluaudia ascendens is a plant that can grow as much as 60 feet tall, although you will automatically be able to restrict this if you grow it in a pot. Even then, the plant can become quite unruly, in which case pruning it back a bit right before the growing season can be ideal.

Make sure you use a pair of shears or scissors to carry this out and cut back around 7 cm of it so that the branches can then form easily.

Potting and Repotting

For the initial potting, you can prepare any ceramic or earthen pot that has a drainage hole. Make sure it is deep enough to encourage the roots to grow freely. You do not need to worry about repotting Alluaudia ascendens too frequently, but if it grows too big for the pot, you should use a bigger pot and some fresh soil.

How to Propagate Alluaudia ascendens

If you can manage to find seeds for Alluaudia ascendens, you can soak them and then sow them in the prepared soil in the pot at the beginning of spring. You can also start them earlier indoors and wait for them to germinate before transplanting them into a pot.

An easier way of propagation is to use stem cuttings. You can do this by cutting off the stems from a mature plant and allowing the stem to dry a bit for a couple of days. Use some rooting hormone during this stage too.

You can then plant the stem in a prepared pot and care for it properly.
