Brrr. Winter is here and you want to take the best care of your lovely adenium. Among all the other species, Adenium Multiflorum and Adenium Swazicum are two of the most cold-hardy adenium. The popular Obesum and Arabicum don’t really take the cold weather very well.

With that said, all of them still need to be watched closely through the cold winter months because the frost might damage them. There are a few key points you should keep in mind. Let's put our gloves on & check them out right below.

1. Overwinter your desert roses

You can overwinter your desert roses outdoors. Placing the adenium in places with absolutely no frost or somewhere bone-dry will help.

Try placing them against a wall or under a roof cover like your porch roof. Make sure no rain or water gets into contact with the plants.

It is okay at this point just to let your adenium go dormant. Cold winter nights might trigger the dropping of the leaves. You can also force this by cutting off the leaves.

If temperatures hit under the 20F, you should move your plants indoors or cover them with at least two layers of covers.

If you want to cover your plants, try using a plastic drape and wrap it gently around the plants. Suspend the layers over the plants to keep them warm.

2. Water for your adenium during the winter

If you’ve already overwintered your plants with temperatures of 50F (10C) or less, then you should keep the plants absolutely dry until the weather warms up and the plants begin showing signs of growth.

This may be in spring or in April. Then you can begin watering your plants again. Remember to thoroughly drench the soil to avoid any salt buildups, especially in terracotta pots.

If you have a small plant in a smaller pot, you may need to water it once a month during the dormancy period. Bigger plants don’t really need extra water because their caudex–the water storage part–will have enough for them to survive the cold months.

3. Indoor care for your desert rose

If you know the outdoor temperatures in your local area are too extreme for the plants, take them indoors before the winter hits.

If you do so, make sure the indoor temperatures are from 55F (13C) and above. If your plants haven’t gone dormant at this time, you may want to force it to do so.

By not watering it for some time, the leaves will begin to drop, and the plants will begin to “fall asleep” during the winter months.

4. Post-frost care

If some of the branches are affected by frost, you can prune them back in spring or when the weather gets warmer.

If you leave them frozen that way, you risk the chance of the stems getting rotted and thus can affect the whole plant.

After winter is over, replant your desert roses into a nice, nutrient-rich adenium soil mix. Give them a comfortable pot to live in and lots of sunlight. Your plants will begin growing and blooming happily again.

Keeping Your Desert Roses Warm

These are a few key points you should keep in mind when taking care of your adenium in the winter. First, you can overwinter your plants outdoors or indoors. Make sure to give them warm, protective covers with at least two layers.

During the dormancy period, keep your plants bone dry. For smaller plants, we may just need to water them once a month. If your adenium roses branches have been frozen, wait until spring to prune or cut them off.

If you have the time, here's a simple guide on pruning desert roses:

How to Prune Desert Roses
If you want your desert roses to grow more branches and bloom more flowers, then pruning or trimming the existing branches down can give you very good results. Although pruning can help, doing so might lead to root rot if we’re not careful. Let’s look at some of the best practices for pruning your a…
