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.

Tahitian Gardenia

Q: I am interested in your Tahitian Gardenia and I would love to try and grow this plant in a large container/fabric pot. The soil here where I live is terrible as it's hard rock, clay, and sand! So I'm not sure if amending the soil would help to plant in the ground? Can you tell me if this will do okay in a container or best in ground? I live here in Las Vegas, NV (zone 9a). Any information would be great to help me make a this decision, I love the selection of cool tropical plants you offer! Also my daughter does Tahitian/Polynesian dance and this would be a cool "topping on the cake" if she could have a live Tiare flower in her performances.

A: Tahitian Gardenia will be doing best if grown in container in your area. In its natural habitat, it grows full sun but also it enjoys mild weather conditions and high air humidity. All gardenias prefer acidic soils. In your area, if planted in the ground, it may be exposed to some harsh conditions: too high temperatures, too hot sun, dry air, and as you mentioned - heavy clay and sandy soil. You can enjoy this plant grown in container, which can be moved as needed away from too much sun during summer months. Use well-drained potting mix. Use plastic pot, do not use fabric or clay pots - soil will dry out too quickly.
Also remember to fertilize this plant on regular basis with a liquid fertilizer SUNSHINE Pikake - Fragrant Flower Booster.
Grow gardenia in full sun or semi-shade during the hottest months. You may spray it with pure water if the air too dry and hot. Enjoy your Tropical Beauty and good luck!

Healthy Plant Food: Q&A from Mr Booster

Encouraging blooms on the Hawaiian Sunset Bell Vine

Q: Please can you advise how to encourage the Stictocardia beraviensis the Hawaiian Sunset Bell vine blooms? Mine is all beautiful leaves and full sun in Miami.

A: Providing full sun, Stictocardia blooms profusely. In your area, it should be happy and thriving. However, keep in mind that these flowers can be seasonal (meaning, not ever-blooming). The good news it, Hawaiian Sunset Bell usually blooms several times a year on and off. In our garden, we have a large plant growing in the ground and covering a whole fence; we see flowers 3 times a year:
- Early Spring
- Summer (sporadically)
- Late Fall to early Winter

Make sure to provide proper fertilizer to encourage blooms. It is especially important if you grow this plant in container (where nutrients are very limited). We suggest the following fertilizer for your Stictocardia:

Establishing Avocado Tree

Q: I received my avocado Wurtz tree yesterday. Per instructions I have put the tree in a pot first. However I am having difficulty deciding what to trim off. Yesterday I removed obvious damaged leaves. However as you can see, the leaves are lighter in some areas and contain yellow and red in some spots. What would you advise? Given this is a critical state as I do not want to shock the tree after the trip, I would like to do everything possible to protect it and ensure viability.

A: Your Avocado tree looks great and healthy overall. You've done excellent job planting it. Wurtz is a good, vigorous variety, while the tree is somewhat dwarf, great for containers.
You are right, it is the best for the tree to leave it alone and do not trim or remove leaves any more, until it starts showing new growth. Then it will be obvious what needs to be trimmed. Reddish/orange color of young leaves is normal. If any spots or dots - no need to remove those leaves yet. Wait until the plant grows more leaves. It needs them for photosynthesis, in order to become stronger.

Keep the tree in bright shade and gradually move from filtered sun to full sun. Water daily. Within a week or two after planting, you can start applying mild fertilizer and micro-elements. We recommend at this growth stage:
