Hardy Plumeria Pudica

Q: I have ordered plumeria pudica from you in March and it is thriving really well here in Rancho Cordova, California. The current temperatures are ranging from 68 to 32 degrees Fahrenheit. My USDA zone is 9b. Does this plumeria pudica survive outside with temperatures dropping in coming winter in CA?

A: From our experience, Plumeria pudica is pretty cold hardy and takes some cold spells in spite of being a tropical species.
Our trees (well-established) took a few hours of freeze with no significant damage.
Potted plants are less hardy than in-ground plants. However, their advantage is, they are easy to move indoors or inside warmer place like garage, etc. If the temperature stays borderline around 32F for a few hours, the plant should be safe as long as warm day temperatures follow a cold night. For longer periods of cold, move the plant inside.
Make sure do not overwater and keep Plumeria on a dry side during winter, since cold and wet is a bad combination and may cause root problems.
Above is the picture of Plumeria pudica tree growing in Cape Coral, FL where low temperatures in winter sometimes go down to upper 20's for a few hours.

To improve cold hardiness of Plumerias and other tropical plants, use SUNSHINE-Epi-T for plant thermal protection and immune system boost.
Make sure to fertilize plants on regular basis to keep them strong and vigorous. The stronger and bigger the plant, the hardier it is!

Fragrant Gold Leaf Orchid Vine

Q: I am absolutely thrilled to see you have this vine. I've tried for years to get this plant! It is so, so rare. It just seemed impossible to find in this country. How do I make it thrive? I am ordering two.

A: We are happy to confirm that indeed we do have this rare vine!
Bauhinia aureifolia - Gold Leaf Orchid Vine - was discovered in Thailand in 1983. It is endemic to Pattani, Narathiwat, and Yala in Southern Thailand. Danish botanist Kai Larsen named this plant and hailed it as one of the rarest plant species of the world when it was discovered in the eighties.
The Thai people call this vine Bai Mai Si Thong. It is a beautiful climber with large, bi-loped leaves (7 inches or more!) and good branching.
Young leaves are a stunning burnt orange to terracotta color for about a week and as they reach full size, they turn green over a couple of days. This is a very rare color for Bauhinia. It produces leaves all the time and this means this vine is always full of beautiful color. With its golden leaves, it sure is reminiscent of Autumn.
This vine blooms from May to November. It bears bunches of small flowers that are delicately fragrant in the evenings. The cultivated plants range flower color from pure white to purple and pink, while the wild ones have often white petals with pinkish patches.
Bauhinia aureifolia needs well-drained soil, full light and good humidity to thrive. It will tolerate a light freeze once established and it is very important to protect young plants.
Gold Leaf Orchid Vine also makes a wonderful container plant with staking or support. It is a must for every rare plant collection!

Best tasting white guava

Q: What's your best tasting white guava?

A: Our favorite white Guava is Viet Nam variety that is also very rare and hard to find. The fruit is very large, up to 6" in diameter, the pulp is very sweet and somewhat crunchy. The seeds are small which makes it more pleasurable to eat out of hand.
Another great feature of this variety, it stays compact and branches do not get leggy, unlike most guavas. It can be easily grown in a container, trimmed to the desired size and it will produce fruit under proper care.

Another cool variety is Indonesian, it also has a large round fruit and very few seeds to compare with others.

And last but not least, if you prefer soft fruit to crunchy, the Peruvian variety is a great choice. The fruit is pear-shaped.

Remember to provide plant food for good production, especially if grown in a container.

Using SUNSHINE Complete Nutrition System

For hydroponics and potted plants

Q: I recently bought both the 5ml of the sunshine epi and the 100 ml advanced nutrition kit. I read on the paper for the Epi not to use any other strong fertilizers along with this but I was wondering if it'd be alright to use both this foliar spray and nutrition watering together?

A: All solutions in SUNSHINE Booster Nutrition System (NPK-macro and micro-boosters) are compatible.
The only exception is Sunshine-Epi - brassinosteroid bio-stimulant. Epi should be mixed with distilled water separately from other boosters. The reason is, it is very bio-active, and if mixed with other compounds, oxidizes quickly which may affect its performance.

Sunshine-Epi solution must be prepared using distilled water and applied as foliar spray only (it only works on contact with leaves and not through the root system). Epi shows extremely impressive results when you apply it before the application of other nutrients because it increases plant metabolism; so all boosters become even more effective if you spray Epi the day before.

When using Micro- and Macro-boosters, you may mix all components in one watering can/tank (except for Epi), using regular tap water. Besides watering root ball, the macro-micro solution can be also used for foliar spray. It is optional, as in some circumstances growers prefer to keep leaves dry at all times: to stay away from mold, fungus and other issues caused by the wet environment.

Here is an example of Sunshine Boosters Nutrition System application:
1. Daily watering in one can: NPK 25 ml/gal (one of 5, depending on growth stage) + Constanta 5 ml/gal + Ca-Support 5 ml/gal, mixed in tap water
2. Every 2 weeks: spray Sunshine-Epi 2.5 ml/gal - to boost the immune system and growth rate, mixed in distilled water
3. From daily to every 2 weeks: Sunshine-Power-Si 25 ml/gal to protect from diseases and keep pH at 5.5-6.5. Can be used as often as daily and mixed with a daily watering solution (1)
4. As needed: Sunshine SuperFood and GreenLeaf - for correcting deficiencies. Can be also mixed with the daily solution (1)

Make sure to prepare a solution right before use and do not store solution for more than 1 day. Keep concentrates and solutions protected from bright sunlight.

NEEM - The Free Tree of India

By Onika Amell, tropical plant specialist

Q: What is Neem oil and tree, and and can we grow the Neem tree here in the US?

A: Neem! What an extraordinary, fascinating tree! I'm personally convinced every garden should have one, if your climate allows it. Neem tree - Azadirachta indica - will very quickly become a valuable shade tree in your garden. They can grow up to eight feet per year! Neem trees are also known to grow very well in areas with infertile soil and under very dry conditions, which makes them perfect for xeriscaping. Not only is Neem fast-growing, but it's a beautiful tree with wide-spreading branches and dark green leaves. It will form a dense, round canopy, up to 60 ft wide.

This wonderful tree has been used by humans for thousands of years. Did you know Neem has more than 100 unique bioactive compounds? Surprisingly, a lot of gardeners are still unfamiliar with it!..
