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.

Plant Horoscope. Scorpio Zodiac lucky plants: Nearly indestructible plants

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.

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
