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 propagate plants from cuttings. Top (Tropicals) secrets.

Q: After pruning my jasmine, I have so many branches and I don't have a heart to through them away, can I use them to make more plants? Please tell me what size cuttings and do I need to remove leaves? Should I just stick them in the ground? Will they root? I don't know if you will be willing to share your secrets?

A: We are always happy to know that you grow more plants, and make our World better! These are some useful tips for the propagation of tropical plants using cuttings:

- Cuttings and leaves. Use cuttings 2-5" long. Strip leaves from the bottom. Cut larger leaves in half to reduce evaporation.
- Soak cuttings for 15-30 min in SUNSHINE solution.
- Mix. Use special well-drained mix with lots of soil conditioner: we have a special professional propagation mix for cuttings.
- Mist. Put community pots or trays with cuttings in mist, or if you don't have mist - cover the pot with a clear plastic bag to create a mini-greenhouse.
- Shade. Keep propagation pots in bright shade and never allow direct sun rays.
- Rooting hormone: yes, use it if you have it. Not only it promotes root formation but also prevents from fungus so the cuttings won't rot. We use Dip-N-Grow.
- Rooting and food. Check in 2-3 weeks for roots. Once you see the little roots, begin fertilizing with a special Baby-Plant Food and make sure never exceed recommended doze otherwise you may kill the cuttings.
- Establishing. Once roots start growing, plant in 4" pots in a well-drained potting mix and watch the beauty grow! Gradually move to the full sun only when little plants establish and start new growth.

If you are lucky to make more rare plants than you can use, contact us, we will buy them from you or trade for your dream plants! In fact, one of our customers from many years ago started selling us baby plants that he propagated from our plants, and now has a successful business (Karma Nursery); we buy a lot of plants from him every month!

Q: I am in Texas, it is getting cold, but I bought these seeds the last two packs, as I didn't want to miss them, was looking for a long time and found you had them. Should I wait until spring to plant them?

A: You can grow tropical plants from seed year round and don't have to wait until warm weather outside. It is, in fact, beneficial to start tropicals indoors in a controlled temperature, moisture and humidity. Seeds of some species are very sensitive to excess water and/or require a certain range of temperature for germination... Besides, it's so much fun!
First, read the basics: Happy Hobby: growing tropicals from seeds

Advantages of indoor growing from seed

It is easier to keep under control indoors:

1) Temperature and Light. Although many tropical seeds require higher temperature and bright light for germination (hot sun may help), it may be hard to avoid overheating and drying out when you put trays in full sun. Using heat pads and additional lighting indoors makes germination smooth, even may take a little longer than in hot sun.
2) Soil moisture. If you ever lost your seeds or tiny seedlings to a heavy summer rain, you sure will appreciate your own moisture-controlled environment! Just make sure to use the right soil mix.
3) Air humidity. Indoor air is drier than outside. It may not be best for some tropical plants, but definitely perfect for seed health - they will never get moldy considering you keep your eye on the plantings.
4) Pre-treatment. Some seeds require scarification (sanding down hard shell), others stratification (cold treatment), but all seeds will benefit from SUNSHINE-S soak before planting. It is easier to do in your home lab. Based on our experience, using Sunshine pre-treatment reduces the risk of fungal damage and improves germination from 30 to 65%.
5) After germination culture. Watching seedlings closely in your home environment and giving them all that is needed for healthy, fast growth - miscroelements and first fertilizer - will help to establish young plants just in time before planting them out in Spring-Summer.

Shipping plants during hot weather. Ship plants now or wait until it gets cooler

Q: Can you ship my plants now or should I wait until it gets cooler? Daytime temperatures here are around 90F.

A: Top Tropicals ships year around. In transit, packages are usually kept in a temperature controlled environment. In hot summer time, it is still safe to order plants in mail, as long as the box is not left at your doorstep in full sun.

Keep your eye at the weather forecast and if temperatures get to extremes (over 95F daytime), we strongly advise that you be present to accept delivery. As your package may be left on your doorstep by the carrier, this prolonged exposure to heat may be harmful to the health of your plants.

If no one is available to accept delivery, we suggest that you contact our customer service to postpone shipment until a later date or coordinate an alternate delivery address, or simply use your work address for delivery - so you can get your plants without delay. You may also use the delivery address at FedEx pickup locations to avoid delays!

We monitor the weather at destination before shipping. When daytime temperatures in your area are over 90F, your shipment may be delayed to ensure plants have a safe trip and do not overheat in the delivery truck. See information on shipping process and terms.

Please contact us for more info on holding orders during hot weather.

More about Mulberries

Customer comment on our Mulberry column in the previous newsletter:

...I planted a Himalayan mulberry, Morus macroura, about six years ago. For several maddening years, it shot only very long, un-branching tentacles out there, and it resisted my efforts to force some branching by pruning. It would send another long, reaching shoot from the tip of the pruned branch, with NO laterals. Several times, it did this. Finally, two years ago, it broke buds that looked like they meant it all along those long branches, and in one season, it fluffed out. The next season it elaborated on this, acting much more like a proper tree. The fruit is fabulous, three or more inches long, very sweet, with a rich berry flavor that's more raspberry than mulberry. I guess it just needed more time. My understanding is that mulberries don't really like to be pruned, but it needed to happen in this case, along a driveway, so I reigned it in, and now it's a treasure. Be patient.
Cheers, your admirer, C
