Healthy Plants: Q&A from Mr Booster

How to prevent mango flowers drop

Q:The mango blossoms my tree had in February have blown off due to weather conditions. Do you know what I can do to prevent this from happening again in the future?

A: The only "guarantee" to protect mango flowers from cold weather damage here in Florida is to plant a LATE flowering variety. Generally, mango trees are winter bloomers. Those varieties called "early season" start flowering in January (for example, Nam Doc Mai), and of course very often they get affected by cold, so they drop. Some varieties are so called "late season" - for example Venus. They start flowering in spring when the weather conditions are more favorable.
Another thing that may help you with mango flower drop is applying plant micro-element supplement Sunshine-Honey - it contains Molybdenum and Boron, which help flower and fruit development/strength and prevent their drop.

Establishing Avocado tree after shipping

Q: Received my Avocado tree last week and I'm a bit concerned. Is this wilting normal with a new plant? No yellowing, or dropping of leaves. We moved it out of the sun but not sure how to handle?

A: This is normal for after-shipping stress. You did right, position the tree away from direct sun, in shade, preferably under roof (patio?) so it doesn't get over-watered with too much rain and you can control water amount. We recommend to spray the leaves with pure water and put a large clear plastic bag just over the crown (leave the soil to breath). Keep in shade. Within couple days the leaves should perk up. Do not overwater. Water only when the top of soil gets slightly dry. In a week or so, once the plant recovers, you may start moving it gradually into full sun, then to its permanent spot where you want to plant it.
Avocado is not an easy plant to establish. So be careful. It needs lots of water, however, it doesn't like wet feet - so must be planted in a well-drained spot, with at least 4-6" elevation (on a little "hill") so it never gets water-logged. It needs daily water to establish and may need more than just a sprinkler system, use additional hose water when establishing in the ground.

Growing Champaka in Virginia

Q: I purchased a Magnolia champaca 1 gallon a few years ago. It is still growing as I bring it into my greenhouse in the winter. I live in VA. This spring I planted it in the ground hoping it might bloom which it did not. Will it survive our fairly mild winters with several freezing days with some special attention? What would you do?

A: Magnolia champaca is a tropical tree and won't survive winter in VA. It can not take hard freeze. Your only option is, to keep it in a pot and bring inside. If the temperature inside your greenhouse is too low, this may affect the plant's ability to flower. For example, if it stays 35-40F for a whole month - although it is not a hard freeze and the plant may survive, but the duration of the cold period is more critical than the low temperature itself. Champaka can survive a few hours even at upper 20's, but not many days with cool temperatures. The temperature in winter should be maintained at least above 55F during day time (the higher the better) and at least above 45F at night.
If the tree has grown too big, you may trim it. If the root ball is too large, roots can be trimmed too (similar way like they do with bonsai) before repotting. However, trimming must be done either during warm season and active growth, or in Spring, when the tree starts waking up and promotes new growth.
To encourage flowering, start fertilizing your Champaka with a liquid bloom booster - SUNSHINE Pikake - Fragrant Flower Booster. It can be used year round including winter months, and it is safe to apply with every watering. This way you will provide to the tree enough energy for the next flowering season, so flowers can be expected in late Spring - Summer.

Champaka - a true Joy of your life

by Alex Butova, the Witch of Herbs and Cats

...Champaka, or Joy Perfume Tree, is regarded as one of the most sacred trees of India and tropical Asia. Its flowers exude a divine fragrance that is exceedingly pleasing to the Gods... and women!..
...The tree was traditionally used to make fragrant hair and massage oils. Jean Patou's famous perfume, 'Joy', the second bestselling perfume in the world after Chanel No. 5, (but definitely the most expensive number one!) is derived from the essential oils of champaka flowers. The plant common name "Joy Perfume Tree" comes from this perfume. Many niche perfumers are now once again using Champaka Absolute as single note fragrances...
Planting a Golden Champaka really makes your home a sweet home. Also you can take the flower into your car, office, restroom, and anywhere you want to create fragrant atmosphere. It emits a unique warm fragrance which promotes a peaceful state of mind, reduces stress and helps you to relax and breathe easily. Looks like it is specially designed for moments of tranquil contemplation. It's the nature of Champaka - to remind us of the Divine in all things...
