Recovering Soursop after shipping and cold

From Irene & Marjorie, PA: We wanted to share our pics with you (after Summer). I attached also the photo of the way the tree looked before your advice (back in April). The big is the one we almost lost and you gave us these instructions and it came back. These were your instructions:
"The soursop is one of my favorite fruits and I was so sad to hear yours may be dead. Good news - the tree looks great! Yes, it does have some cold damage but I'm surprised it still has leaves on it at all! In cooler weather, they typically drop all of their leaves and stay that way until spring. You can remove the damaged leaves and it will resprout new growth with the warmer temperatures."

Taking care of Soursop after shipping
Soursop - Annona muricata trees are very sensitive to temperature drops. This always causes leaf loss. After shipping, do not water until the soil gets slightly dry; keep it in bright shade. No fertilizer until the plant shows active new growth. Be patient with your plant, and it should recover soon.
Soursop is an ultra-tropical tree and doesn't take any freeze. If you live in a cooler climate, keep the plant in a pot (the good news is, Annonas, in general, have a compact nature and are perfect for container culture). Bring the tree indoors during the cold period, providing bright light.
We have a very interesting article about growing and fruiting Soursop in an apartment. Check out 4534 Tropical Treasures Magazine # 7.

A Sacred Earthworm: benefit or damage?

by Mark Hooten

Q: We have lots of earthworms in our soil. I've heard they are beneficial for the plants, it it true? Or should I try (and how) to get rid of them at least for container plants?

A: From my earliest childhood, I remember learning that "earthworms" are wonderful, beneficial creatures for our gardens. I had heard that they improved the soil by both aerating it via the tiny tunnels they dig from burrowing activities, AND leaving their droppings which act as fertilizer. However, both my personal experiences and studies have shown otherwise. The truth is that the vast majority of earthworms we encounter in our daily horticultural practices are not even native to North America. In fact, they were introduced from Europe, beginning with the colonial period, mostly accidentally in things like the ballasts of ships, and from soil from around the roots of plants being imported. However, once they arrived here, they began to irreparably alter the natural eco-systems of our forests... Continue reading...

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.

Avocado, Lychee and Mango setting fruit... give them some FOOD!

Q: Do I need to fertilize tropical fruit when they set fruit?

A: It is traditionally believed that mango and other tropical fruit shouldn't be fertilized during fruiting period. It is true to an extent: you don't want fruit to burst from fast excessive growing. Instead, try to feed fruit trees wisely, because they still need proper nutrition to produce flowers and fruit.
Our spring specials of Lychee, Avocado and Mango are full of buds and some already set tiny fruit (see examples on the photo). Here is the feeding plan for these plants once you receive your mail order:
1) Once received the plant, pot it into container size of the root ball and let establish for couple weeks. Use SUNSHINE-E to help the plant recover from shipping stress and establish root system.
2) Apply SUNSHINE-Honey right before flowering, and next time at setting fruit, to provide sweeter and bigger fruit, eliminate fruit cracks and help resist fungus and other fruit diseases.
3) Use balanced granulated fertilizer, 1 tsp per each gallon of soil. Apply once a month during Spring-Summer season. This gives the plant balanced macro-elements (NPK) necessary for overall plant health. Do not use on fruit trees fertilizers with high Nitrogen content.
4) Apply SUNSHINE SuperFood micro-element booster to keep fruit trees vigorous, develop strong root system and avoid deficiencies.
5) In case of signs of chlorosis (yellowing leaves with darker veins), give the tree SUNSHINE-GreenLeaf and watch the leaves turning green quickly.
After harvesting, don't forget to make another treatment of SUNSHINE-Honey as a preparation for the next year flowering and fruiting season.
