How to Grow and Care for Haworthia Coarctata
Haworthia Coarctata is an easy-to-care-for succulent that you can grow indoors or outdoors. It makes for a great filler for your rock garden and as an ornament adorning your windowsill.
The Aloe Coarctata is not cold-hardy and can thrive in locations with temperatures of -1.1° C (30° F) or higher.
Haworthia Coarctata enjoys full sun. However, direct exposure to the midday sun will scorch the leaves.
When planted outdoors, make sure to place it in a location where it can get at least 6 hours of sun in the early morning and late afternoon.
Exposure to little sunlight will cause etiolation. The leaves of your Haworthia Coarctata will stretch thinly towards the direction of the light source.
If you will grow Aloe Coarctata indoors, place the pot on your windowsill where it could get at least 6 hours of bright light.
Haworthia Coarctata does not require frequent watering. Remember that overwatering will damage the roots which can lead to your plant’s early demise.
Allow the soil to dry out completely before you water again. Before you water, insert a stick into the soil to ensure that there is no moisture left. If the soil is dry, soak it with water.
Avoid pouring water into the rosettes because the trapped water will cause fungal rot.
Come late fall, start to reduce your watering. During winter, water your succulent plant every other month.
Pot and Soil
Your Haworthia Coarctata will grow healthy if you pot them in ceramic or terracotta containers. These are made of breathable materials which will prevent soil moisture retention.
When you purchase succulents from nurseries or plant shops, they are often planted in plastic or glass containers. Make sure to transfer your Haworthia Coarctata into pots suitable for succulents.
Cactus mix is the best soil for your Aloe Coarctata. You can also use garden soil mixed with organic matter and gritty materials such as sand, gravel, pumice, or perlite. This combination allows water to drain fast without losing the soil nutrients needed by your plant.
Use fertilizer that’s specifically formulated for succulents. You can add fertilizer to the soil during summer when Haworthia Coarctata actively grows. Refrain from using fertilizer during winter.
How to Propagate Haworthia Coarctata
You can propagate Senecio barbertonicus via leaf and stem cuttings. Summer and spring are the ideal seasons for
The best time to propagate your Haworthia Coarctata is during spring. They will be ready for transplant by the end of summer.
There are three ways to propagate Haworthia Coarctata: Offsets, leaf cuttings, or seeds.
Method 1: Leaf Cuttings
Step 1: Choose firm and healthy leaves.
Step 2: Cut them from the plant using a sterilized and sharp knife or a pair of pruning shears. You can also twist them off gently from the stem.
Step 3: Leave your cuttings in a warm and dry area for 3 days to allow them to callus.
Step 4: Lay your callused leaves on a well-draining potting mix.
Step 5: Place your container in an area exposed to partial sunlight. Mist the soil 4 to 5 times a day. Transplant your new Aloe Coarctata after the roots and new rosettes have formed.
Method 2: Offsets
Step 1: Check if offsets have already sprouted on the base of your mother plant.
Step 2: Gently pull the offsets from the soil.
Step 3: Place them in a warm area and allow them to dry for 2 to 3 days.
Step 4: Replant your dried offsets in a container filled with succulent soil mixed with gritty materials.
Step 5: Place your pot in an area exposed to indirect sunlight. Use the “soak and dry” method of watering.
Method 3: Seeds
Step 1: Fill your container with sterilized potting soil to prevent weed growth during germination.
Step 2: Place your Haworthia Coarctata seeds on top of the soil.
Step 3: Water the soil until it is fully soaked. Make sure that you keep the soil damp every day. Place the container in an area where it will get a lot of bright light.
Step 4: When your seedlings start to sprout make sure to spray your soil with water regularly to stimulate root growth. Do not water the crowns of your baby succulents to prevent fungal rot.
