Care of Desert Roses

Q: I am looking forward to my three desert roses I just ordered from you and I am wondering how to take care of them, especially during winter time. Should I put the pots in full sun or shade? What kind of soil do they like? How often should I water them? When it gets cooler, should I bring them inside? We do have occasional frost here during winter.

A: Here are a few tips for your desert roses:

1. When received Adenium from mail-order, unpack carefully; branches are fragile. Plant in well-drained potting mix. Cactus mix will do, but we recommend special Adenium mix. If using regular acidic peat-based potting mix, you may add sea-shells on top of soil to neutralize acidity: adeniums prefer alkaline soils. Using clay pots is beneficial. Water once and do not water again until soil gets dry. Place in bright shade until new leaves sprout, then the plant can be moved to full sun.

2. Adenium is a succulent, but not a cactus. It needs watering, however let soil dry before waterings. Reduce watering during cool season and discontinue when plant gets dormant (drops all leaves in winter).

3. Bright light is the best for profuse flowering. However, adeniums look much healthier in slightly filtered light rather than in all-day full sun.

4. Fertilize and spray leaves with liquid fertilizer SUNSHINE Megaflor - Nutrition Bloom Booster. Phosphorous is responsible both for flowering and caudex development. Avoid caudex, spray over foliage only. Dry fertilizer can be used only during hot months.

5. Watch for spider mites during hot and dry season.

6. Give plants a break during winter dormant season. Keep in bright shade and reduce watering to 1-2 per month or stop watering if temperature is below 65F.

Growing desert roses

Q: I purchased a Desert Rose and planted it in Adenium mix. I keep it in full sun with once a week watering assuming this is a desert plant that likes lots of sun. Some leaves turned yellow and now I am not sure should I move it into shade or need to water more? Or maybe fertilize with something?

A: Desert Rose - Adenium, unlike cacti and other succulents, prefers filtered light. It can grow in full sun but leaves look healthier in light shade. Watering must be very moderate, however don't let soil harden like a rock: water again right after the soil gets dry. We suggest to use special Adenium Mix. Cactus mix may work well, as well as regular potting mix, in which case it is recommended to add a bit of limestone (we simply put sea shells on top of the pot - it looks very pretty!) - because adeniums prefer slightly alkaline soil (while most of tropical plants like acidic soils). If leaves turn yellow, this may be a sign of underwatering. Use water soluable fertilizer with high phosphate as foliage spray, and only on healthy plants, according to label dosage. It helps both caudex growth and flowering. Make sure to avoid fertilizer contact with a caudex.

How to get shade quickly... and stay away from oaks

TopTropicals

Q: I just moved from Tennessee into a new house in Florida and there are no trees on the property, the yard is brutal hot. What can I plant so I have some shade real quick? I like Florida shady oaks, how long will they take to grow?

A: First of all, do not rush into oak solution. Oaks are beautiful shade trees, however they have at least 2 problems:
a) Oaks are slow growers and unless you are willing to wait some 20 years... you won't get that desirable shade that quickly.
b) We have hurricanes in Florida... sometimes. A hurricane can damage any tree, however with oaks it may be the worse case scenario - the branches of those giant trees are huge, hard and heavy and in unfortunate situation when you need to remove or trim a broken tree, it may cost you... a few thousand dollars.

These are solutions that are more economical and practical:

1) Selection. If you have room, get one of these most popular Florida shade trees: Royal Poinciana, Golden Shower, Hong Kong Orchid Tree, Red Kapok, Bottlebrush, and many others. See full list of fast growing shade trees. Or simply get a Mango Tree and have delicious fruit too! Many varieties of Mangos are very large and fast growing.

2) Do it right. Even if you are planting a smaller tree, 1-3 gal size, it may become a nice shade tree within 2-3 years and start providing your driveway with desirable shade. The keys for fast growth are -
a) Good soil. Dig as big hole as possible and fill it with good rich soil containing compost. See planting instructions PDF.
b) Water. Do not rely on sprinklers and rains. Water your tree daily for the first week, then at least twice a week for another month. After that, irrigation system will be enough.
c) Fertilizer. Put a few handfuls of fertilizer in a planting hole. Then fertilize once a month during warm season. Apply micro elements for even better results and faster growth.

3) Ask experts. Contact our office for advice. We will suggest the most suitable shade tree for your yard based on features of your property: location, soil, exposure, etc.

Full Sun Garden vs Shade Garden

"Someone is sitting in the shade today because someone planted a tree a long time ago." (Warren Buffett)

Q: I live in California and I have a large area of my garden in full shade. Are there any plants that will be happy there? I am looking for something colorful. I also have a smaller area in front of the house that has full sun almost all day long, but I am afraid this can be too hot for flowering plants? Can you recommend something?

A: Full sun gardens have a strong, bright look while shade gardens have cooler, subdued appearance. Both types of gardens are fun to design and maintain as long as you pick the right plants.
Full Sun Garden is the easiest to grow. Depending on exposure, it may require some plants that can tolerate the hottest summer days and the dry conditions in your area. The good news is, the majority of tropical and subtropical plants prefer full sun, so you have a large selection to pick from - fruit trees, flowering trees, shrubs, vines, and small perennials. The more sun, the more flowers and fruit you will get! However, keep in mind that sun gardens require more water, but generous mulching will help to minimize watering.
Shade Garden is much more restful in appearance, but sometimes may be a little more difficult to work with. As shade trees grow bigger and thicker, it may become too dark; nothing will grow in total darkness. In this case you need to prune back some branches to let more light in. Filtered sunlight or dappled light coming through the leaves of the trees is beneficial and considered light shade, which would be the best light conditions for shade loving plants to thrive. Although shady cooler spaces attract more insects and will require more attention to control them, they also have some advantages over sun gardens. You can enjoy working in cooler conditions, and your garden will require less water. Many foliage plants look more deeply colored and healthier than in full sun; white flowers shine instead of looking washed out!
Our favorite shade plants are fragrant brunfelsias , clerodendrums, and of course colorful gingers and heliconias. You may also consider ornamental foliage of Calatheas, lush Alocasias, Colocasias, and colorful Cordylines. Check out our shade loving plant list for more colorful suggestions. These are also great for indoor gardens!
