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.

We have limited stock, while supply lasts, hurry up!

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!
