Acacia (Vachellia) sphaerocephala - Bulls-Horn

The name of this cool unusual tree comes from the shape of the thorns which do indeed resemble the horns of a bull! The tree has a strong, symbiotic relationship with a species of an ant, Pseudomyrmex sphaerocephala for which it is the obligate habitat. The ants act as caretakers for the tree, and clear the ground and keep it free of any other plants and even prune surrounding branches of other trees that threaten to outshade the acacia. Without the protection of the ant colony, the acacia tree would fall vulnerable to chewing insects such as beetles or caterpillars, and surrounding trees and shrubs would quickly outcompete the acacia without the maintenance work of the ants to keep the tree safe.

Hawaiian Dwarf is a True Star!

By Mark Hooten, the Garden Doc

Q: I live in Southern Ohio and love growing lots of tropical plants. In the warm months, they all go outside under the protection of tall trees, but in the cold months, they all come inside in a snug but very brightly lit sun-room. For many years I have successfully kept a dwarf Meyer's lemon which amazes my friends, and I am wondering if you could suggest some other dwarf tropical fruit tree which I might be able to grow that would amaze them even more?

A: Without hesitation, I would strongly suggest a particular variety of carambola (star-fruit) called Dwarf Hawaiian, as it is truly special as tropical fruit trees go. First and foremost, they begin fruiting at a very young age, often while only in a one-gallon pot, and even less than a couple of feet tall with a very little trimming. Better even is that they are perfectly happy living perpetually in a pot. I have one myself which is content in a 12 inch pot and which fruits freely throughout the year. Also, even though it should be too much to be expected, the fruits are of the highest quality and are as sweet as candy. I also like the fact that the fruits hang decoratively on the tiny tree for quite some time before finally ripening, rather like ornaments. One of these little trees in-fruit is an amazing sight and ought to make anyone take notice, especially in a sun-room in Ohio! They really are very easy to grow, and if you have a Meyer's lemon which does well, you'll certainly have no particular issues with a Dwarf Hawaiian carambola.

However, I have found that in order for them to remain extra dwarf and fruit especially precociously, this variety needs to be grafted and not cutting grown. Fortunately, Top Tropicals has recently obtained a number of these extra wonderful grafted trees which are of the highest quality I have seen in some time, all of which will likely begin fruiting very shortly. They simply are wonderful little trees! Check them out...

Spring mulching

Q: When do I start re-mulching my garden? Should I wait till summer?

A: It is time now to get ready for the growing season when not only plants start growing, but weeds as well. To protect your garden from unwanted invasives, keep a thick layer of mulch in areas around tree trunks and shrubs.
Heavily mulch your garden at least once a year, at springtime. Add mulch during the year as needed.
After mowing your lawn, use cut grass (hay) as a mulch around trees. Hay is the best natural mulch, it compresses well after the rain or watering and becomes very dense - weeds won't grow through it. You may cover it with some colored mulch of your choice for a more attractive look.
Mulching is also helpful for retaining water for root systems, so plants will require less frequent watering.

Spring tips

Once temperatures stay above 65F, growing season starts for tropical plants.

1. Increase watering as soon as you see new buds opening and new leaves growing

2. Trim all dead or damaged wood 1-2 inches above new growth

3. Apply the following treats to make your plants happy:

- granulated balanced fertilizer

- SUNSHINE Superfood microelements as foliar spray for healthy growth, profuse flowering, and disease/bug resistance

- SUNSHINE-E to help plants come out of dormancy faster and increase metabolism. 100 ml bottles and 50 ml bottles available for large plant collections.

- SUNSHINE-Honey to fruit trees so you can enjoy sweeter and bigger fruit later this year

4. If nights are still chilly, take potted plants outside to enjoy the afternoon sun and bring them back indoors for the night.

Champaca tree during Spring

Q: The Joy Tree that I purchased from you is going fine but the leaves have brown tips that shriveled up. How can I avoid this?

A: All Magnolias prefer rich and moist soils. These are some useful tips for growing Magnolia champaca:
- when planting in the ground, dig a big hole and replace sandy old soil with a rich organic mix containing compost and lots of peat moss to retain moisture.
- water daily for the first few months until the tree is well-established and root system is large and strong.
- use a large amount of mulch around planting
- remember that during springtime (especially March through May) champacas go through the semi-deciduous stage and lose a lot of leaves. Sometimes the tree may start looking drying out - all the sudden, overnight. Give it a few weeks and you will notice new light green re-leafing that will dress up your tree when the time comes.

Pisces Zodiac lucky plants

Pisces- 2/19 - 3/20. As a WATER sign ruled by both Jupiter and Moon (and Neptune, that was not discovered until 1846, after the plant correspondences were established; Neptune is considered a "higher octave" of the Moon), Pisces plants are often large but hard to find, and may grow near the ocean. The most healing plants for Pisces are those that strengthen the immune system or have an antibacterial effect. Pisces plants may also catalyze expanded states of awareness and be helpful in dream work.
Herbs connected to Pisces are ruled by its former ruler, the Moon (Neptune, the current ruler, was not discovered until 1846, after the plant correspondences were established; Neptune is considered a “higher octave” of the Moon). Diseases of Pisces have traditionally included psychotic disorders, various forms of substance addiction, lung diseases such as tuberculosis, and ailments of the foot; contemporary herbalists also add immune system diseases. Pisces is strengthened by rosemary's ability to promote an aura of centered grounding. This protective herb helps strengthen boundaries and cultivate a closer connection to the physical realm.

Australia Planting 1 Billion Trees To Fight Climate Change

Australia plans to plant 1 billion new trees to fight climate change, by the year 2050. That is a lot of trees and is the first real effort the country has made toward combating climate change. The only real problem is finding enough space to plant that many trees...
A billion trees is a billion trees, and even with a team of 30,000 people planting a tree per day for the next 31 years, the final tally would still only be 339,450,000 trees. Australia will need a tree army to get that many trees planted by 2050... Read the whole story...

How about planting just one tree today and save the World one step at a time?

Deciduous plants soon sprouting

Many people believe that living in a warm climate will dissuade a plant from its deciduous nature. However, deciduous plants react to not only temperate but also shortened hours of daylight and changes in precipitation. Additionally, some plants will drop foliage in phases between new growth, and others use abscission to aid in pollination; blooming without wind-blocking leaves and making flowers more visible for insects.

When pruning a deciduous tree or shrub, it's generally best to wait until late winter or early spring, before the plant begins to leaf out. Avoid pruning during periods of new growth; during this time, the plant is weakened by the struggle to reestablish its growth process. Before pruning your deciduous plant, first research the specific plant, as there will always be exceptions to general instruction. For example, many Rubus varieties desire to prune in late fall, as their buds are developed during the dormant winter season. Some trees may have flower or fruit during winter while having no leaves, give them a chance to flower before pruning.
