Cold protection - winter action for your plant collection

A note from our customer: Last winter was very cold here in Arizona, lower 30's. I used white synthetic sheets (called frost cloth, it is very light and yet effective) to cover my fruit trees, and kept simple light garlands on for the whole night. Sending you couple photos so you can share with others. It worked pretty well for my plants and no cold damage!

With winter approaching, it is time to take some actions to protect your rare plants from cold stress and damage.
If you live in a mild climate, you still need to get ready for the cold nights. When expecting a cold night, individual plants and trees can be wrapped with sheets, or blankets, to protect them from the wind chill. Christmas lights is a good idea for an additional warm up.

For large collections of tropical plants, temporary winter greenhouse doesn't have to be expensive. An easy-assembly mobile carport from a hardware store covered with a plastic or fabric will cost you $100-200. It can fit a hundred plants or more!

If you live in area with a hard freeze, Southern exposure windowsill will work for most of the compact tropicals providing proper care. Larger collections may also move into your garage for a few cold nights, or for longer periods if the garage has a bright light source.

Factors affecting tropical plant winter survival:

1. Duration of cold period. Tropical plants can't stand long periods of cold. A few days of even upper 30's may kill a tropical plant. A few hours of frost may cause leaf drop but the plant will recover.
2. Minimum temperature - of course, the warmer the better. But see 1) - if cold is not for too long, it may be OK.
3. Wind-chill can be more dangerous than low temperatures.
4. Exposure. Southern slopes get warm during daytime and stay warm longer.
5. Protection with a house, fence, larger trees - where a "pocket" of warm air forms and stays - is beneficial.
6. Humidity. A lake or a river nearby (especially ocean) will mild the micro-climate.
7. Individual species hardiness. Don't try to grow Orchid Tree outdoors in New York.
8. Plant maturity and health. A well-established plant with developed root system has more chances to survive cold. If a plant had a good change to develop during warm season (bright light, enough water, fertilizer), it will be more cold hardy. Healthy plant can withstand lower temperature, so proper nutrition is important, including micro-element applications. Large specimens, even ultra-tropical, may survive cooler winter than they normally do in their natural habitat. The Nature provided plants with better hardiness level than it is normally used. To boost plant immune system and improve cold tolerance even more, use SUNSHINE plant boosters. SUNSHINE-T - thermo-protection booster, is specially formulated for winter protection of tropical plants. To improve cold hardiness, spray 1-2 days prior to cold with 5 ml/1 gal solution and continue applications with 2.5 ml/1 gal solution every 10-15 days throughout winter period.
9. Gradual temperature decrease is less dangerous than a sudden drop since it gives a plant a chance to adjust. One sudden freeze in December with prior warm fall may create more damage than a gradual temperature adjustment. If it starts to get cold early in the Fall, plants slow down their metabolism, and the new tender growth won't get hurt later in winter, since the plants are "expecting" the cold.
10. Do not fertilize plants during cool months. Not only because they don't need much food beyond growing season, but also because fertilizer (especially Nitrogen) encourages rapid tender growth that will be damaged by cold and this will stress the whole plant.

Stay warm!

Taking care of Guanabana (Soursop) after shipping

Q: Since I have never grown a soursop tree before I need some pro help. My tree was delivered absolutely beautiful, leaves were a pretty green. I potted it and gave it a good drink of water and put it in a shaded area outside. Then the weather here became cool so I brought it in for a few days until the weather warmed, and it lost all the leaves. Is it in shock and will come around eventually? Will I be able to grow this tree indoors during winter?

A: Soursop - Annona muricata trees are very sensitive to temperature drops. This always causes leaf loss. You seem to be doing everything right. Do not water until soil gets slightly dry; keep it in bright shade. The weather should be good now with high temperatures and humidity rising. No fertilizer until the plant shows active new growth. Be patient with your plant, it should recover soon.

Soursop is an ultra-tropical tree and doesn't take any freeze. If you live in cooler climate, keep the plant in a pot (the good news is, Annonas in general have compact nature and are perfect for container culture). Bring the tree indoors during cold period, providing bright light.

Remember that grafted trees start flowering and producing fruit right away, unlike seedlings of Soursop that may take a few years till fruiting.

Growing Vanilla Orchid

Q: I want to buy Vanilla orchid and I wonder if I can grow it in my bathroom by the skylight.

A: Growing Vanilla orchid is no different than other orchids. It is very simple. All that the plant needs is a good light, good air humidity, and good porous support.

Light. Grow Vanilla orchid in a very bright light, but protected from direct hot sun.

Air humidity.The higher the air humidity, the better your plant will grow. Many people grow orchids in a bathroom where these plants can enjoy occasional "humidity treats" after showers.

Growing media. Vanilla orchid cuttings are rooted very often in a regular potting mix with high content of pine bark and/or Perlite, Coconut Husk Chips. Once the little plant is well-rooted and starts developing, it will need a special porous surface to climb on and to attach to with developing aerial roots. A log covered with porous bark is used often. Another option is a piece of wood wrapped with a burlap fabric. In the Nature, this plant climbs up high onto trees and attaches to the bark with aerial roots - at this point, it doesn't need those terrestrial roots any more which may even die off. Climbing a porous support is absolutely necessary for your vanilla for setting buds, flowering and producing vanilla beans. If you are lucky to live in frost-free climate, plant you vanilla by a tree that will provide a shady canopy and a great natural climbing surface (bark). You may see the flowers as soon as within 1-2 seasons!

Mysterious Night Blooming Cactus - Epiphyllum. How to grow it?

Q: My friend has a huge Queen of the Night Cactus, and the blooms are so gorgeeous! She gave me a cutting but I am not sure how do I plant it? How long will it take till it starts blooming? Is it true that it has only one flower once a year and only at night?

A: Queen of the Night is a very popular and yet mysterious plant. The flowers open once a year after sunset for one night. However the flowering period can last a month or two during the warm season. So each flower lasts only one night, but there will be more flowers to come! In the Nature, Epiphyllum oxypetalum - Queen of the Night - grows on trees in the jungles of Central and South America. It is actually very easy to grow as an indoor plant in colder climates. Here is South Florida we grow them outside in hanging baskets. This is how to start Queen of the Night from a cutting:
1) Put the cutting in a dim, dry place for three days, with no soil and its base exposed to the air, so it will form a callus.
2) Fill a 4-6-inch pot with slightly damp potting soil or succulent mix. Insert the cutting 1 or 2 inches into the soil and tamp the soil around its base.
3) Place the pot where the cutting will get bright light, but no direct sun. Spritz it occasionally with a spray bottle of water to keep the soil only slightly moist. It should root in couple weeks.
4) Keep the plant on an east- or west-facing windowsill where it will receive direct sunlight only in early morning or late afternoon. Water the cactus until water runs out of the pot's drainage holes. Dump the excess out of the pot's saucer immediately, and wait until the surface of the soil is dry to the touch before watering your cactus again.
5) Fertilize once a month from March through October with a balanced plant food, and apply micro-elements once a month for a healthy vigorous growth. Refrain from feeding the plant in December and January.
6) Position the cactus in partial shade under a porch roof or tree, if you decide to move it outdoors during the summer. This plant likes summer humidity!
7) Repot the cactus only once every two years or so, to keep it slightly root bound. Wait until after it flowers in summer, and repot it after it blooms. Prune off any damaged growth at that time as well.
8) Move the plant to a cooler room over the winter months, one that remains dark during the evening hours with temperatures above 45 degrees. Reduce the frequency of watering, waiting until its soil is dry. Resume regular watering in March.

If grown from cutting, it may take 2-3 years until the plant starts blooming, so if you don't want to wait that long - just get a blooming size plant from our store!

Scorpio - 10/23-11/21. A WATER sign ruled by both Mars and Pluto.
Scorpio's plants are often found in remote places or on poor ground. They will likely have thorns, can be red in color, and grow under adversity. The good news is, most of these plants are nearly indestructible! This makes them desirable for every gardener.
The reproductive organs are ruled by Scorpio, so these are plants that balance the hormones, regulate the menstrual cycle, help with childbirth and pregnancy. Until this century, Scorpio was ruled by Mars, and the herbs associated with it had to do with the urogenital system and the colon. Many of the herbs related to Scorpio are cleansing and revitalizing. Now, astrologers assign Scorpio to Pluto, discovered in 1930 (Pluto is said by astrologers to be a higher octave of Mars). Physiologically, Scorpio involves the processes of catabolism and anabolism, the death and regeneration of body cells. Diseases of Scorpio are often involved with the slow buildup of toxic substances in the body (carcinogens, etc) or in the mind (anger, jealousy). Scorpio loves a spice with depth and complexity. Camphor Basil adds rich flavor to every dish it seasons, and its own aphrodisiac tendencies appeal to Scorpio's lusty nature.

Easter Lily Vine creates a fragrant privacy fence of virtually unlimited size

By Ron, South Florida. Easter Lily Vine (Beaumontia grandiflora) is a magnificent woody evergreen climber of unlimited growth potential. A branch of this vine will grow simply until you cut it. I have branches of up to 30 ft. and longer.

I've used two plants to turn a chain-link fence into a privacy screen that is 40 ft. wide by 10 ft. tall, but even a single plant can cover a much wider space if trained properly.

Easter Lily Vine's growth rate is moderate, so it doesn't require constant pruning to keep under control like other vigorous vines. I bought mine in 7 gallon pots, and planted them in the ground immediately. It took about 2 years to completely cover the fence. Since then, I prune it 3-4 times a year.

Keep in mind that these plants are heavy and require a solid structure as support. They twine by nature, but only around items with 3” diameter or more. Mine twined around a near-by lighting pole!

The absolute key in training Easter Lily Vine is to force it to grow horizontally. I recommend planting a young 3 gallon size vine in the ground diagonally, so it grows horizontally. Tie it no more than a foot above ground and let it grow a single branch until the end of the space you want to cover. Then force it to make a U-turn and let it grow the other way. See the following diagram for illustration..

Growing tropicals from seeds.

From Kristi the Wizard of Rose: I grow many plants from seeds, both for my personal collection, and for TopTropicals. I receive many questions from customers who want to grow tropical plants from seeds. Some of them live in colder climates and try to extend growing season of their tropical collections by starting new varieties early in the year from seeds. These are a few tips that may be helpful.

Q: What do I need to do to speed up germination process?

A: Many factors affect germination. Considering you get fresh seeds (for example from TopTropicals) and Mother Nature gives them a good kick start, there are a few things that may speed up germination:
1) Scarification. Large seeds with a hard outer shell can be slightly sanded down just enough for moisture to get inside to wake up the seed during the pre-soaking. Be careful not to damage the seed. See example of Lotus seed scarification.
2) Pre-soaking. We recommend pre-soaking most of the seeds for only a few hours (3-8 depending on species. Some seeds are very sensitive to moisture and may start rotting if stay wet without air circulation. Small seeds, especially tiny ones like dust, should not be soaked.
3) SUNSHINE-S treatment. Adding a few drops of SUNSHINE-S booster when pre-soaking seeds increases their germination rate 3-5 times.
4) Temperature. Warm temperatures help germination. If grown indoors, put seeds containers or trays in the warmest spot of your house; you may use heat pads. Outdoors, putting them in full sun helps a lot, just don't let soil to dry out.

Use only special porous seed germination mix to provide air circulation and prevent seeds from rotting.

Q: Should I keep seeds in refrigerator before planting?

A: Do not refrigerate tropical seeds. Stratification (treatment with cold) works only for temperate species, and some subtropical (like non-tropical Magnolias)

Q: How do you grow eucalyptus from seeds? I tried a few times with no success.

A: The secret of germinating tiny seeds like eucalyptus is - to sow them on top of the moist soil surface (soil must be very fine and soft), without covering. Keep container covered with clear plastic, in bright light. Use spray bottle to keep surface moist but not soggy. I have a customer who germinates eucalyptus seeds using an old fish tank, covered with a glass. Perfect environment - bright light and moist all the time.

Elephant Foot, Turtle Shell - back in stock!

Dioscorea elephantipes.
Dioscorea is a curious plant with tuber above ground level covered with layers of corky bark, resembling a caudex. It is a slow growing, very unusual succulent. Tuber contains saponins, originally cooked and eaten as a famine food by the Hottentots. Caudex that grows up to 6' in nature, resembling an elephant's foot and looks as if it is segmented into geometric patterns (smaller plants look like tortoises) and looks dead but is actually a living tuber. A plant with 18" caudex can be almost 100 years old! The plant grows into a vine with attractive heart-shaped leaves and small yellow flowers. Culture is relatively easy. The vines may die back and regrow several times a year, depending on the particular plant and your region. The plant doesn't send down deep roots, so plant in a shallow pot about 1" larger than the diameter than the caudex. Potting soil should be very porous/loose so that there is easy drainage. Water well around the edges. Keep in a warm area and wait for the first shoots of the vine to appear. Water regularly from that point on. The plant should not be kept damp as with other tropical plants. Allow it to dry before watering again. Many books will say that they are winter growers, because they are native to the southern hemisphere. In fact, they grow in all seasons! Let the plant be your guide. You cannot force them to grow, and over watering will simply cause them to rot.
Elephant Foot is a collectors item, but remarkably easy to grow. It will be with you for years with no effort. It is a wonderful conversation piece! See more info about Dioscorea elephantipes.
