7 secrets of a Happy Avocado Tree

Q: I purchased an avocado tree from local garden centers three times but every time it dies on me. My neighbor has a nice tree in his yard and it grows beautifuly. I just purchased one online from you and I need to know what I was doing wrong? Are there any secrets how to make an Avocado tree happy? I have a big garden and several mango trees, but no luck with Avocado...

A: Avocado tree is famous for being such a pain to establish. But once it starts growing, it's growing! We will share a few simple tricks how to make it right.

1. Plant high and provide good drainage. Wet feet is number one reason for failing an avocado tree. It doesn't like wet soil and won't tolerate soggy conditions. Plant it in the highest spot of your yard and slightly on a "hill" (3-4" higher than the surrounding ground).
DO NOT plant Avocado tree in low spots or wet spots of your yard. Save those spots for Cannas or Black Sapote or even a Mango if you want a fruit tree there.
2. Use quality soil. Use only well-drained soil with high content of organic matter. You may add compost to existing sandy soil, or add some professional potting mix that contains pine bark and perlite. Remove rocks from the hole if you see any while digging. Dig a big hole and fill it with a good soil; compact the soil in the hole very well before setting the root ball. Reminder: plant the tree high!
3. Water regularly. After planting an Avocado tree in a nice high spot with a good drainage, start watering it... daily! Avocado likes water, although it doesn't like wet feet! Once you figure out this combination, you've got the recipe of success. Water by hand daily for the first week after planting, then twice a week for couple weeks, then once you notice new growth - you may rely on sprinklers, but keep watching the tree and don't let the soil over-dry. It must be slightly moist, but not soggy.
4. Fertilize. For such finicky tree, we suggest mild formulas of fertilizers. Dry fertilizers may burn roots, especially of a young tree. Even smart-release granulated fertilizers should be used very carefully. The best way to feed your young avocado tree - get a complete set of Sunshine Boosters Pro system. It has all necessary elements for all stages of plant development and never burns the roots. Sunshine Boosters Pro can be used with every watering - no need to guess how much and when. Besides, it is a natural fertilizer based on amino acids - exactly what you want to use on your fruit trees and other edibles!
5. Boost immune system of the tree. Apply Sunshine Epi plant hormone every 2 weeks as a foliar spray to boost immune system and metabolism of the tree and protect it from diseases. Epi makes plants (especially young plants) grow twice faster! It also enhances effect of fertilizers by increasing plant metabolism.
6. Do not prune until you see significant growth. The tree is small and can use as many leaves and branches as possible for photosynthesis and healthy metabolism. We suggest to avoid pruning for at least the first year. On the second year your tree most likely will be covered with flowers (assuming you followed fertilizer program). Let it go through the blooming stage and setting fruit; prune in Fall after fruiting is over.
7. Keep number of fruit to minimum for the first crop. Don't let the small tree exhaust itself. Keep just 2-3 fruit to develop. The next year, no need to control fruit quantity, the tree will develop as many as it can support.
P.S. If you got the tree from a mail-order, remember to establish it in a pot before planting in the ground; move gradually from shade to sun. Follow planting instructions.

Flavor of Feijoa Superfood

by Onika Amell, tropical plant specialist

Q: What exactly is Feijoa - Pineapple Guava? Does the fruit really taste like pineapple? I am curious to know if it is easy to grow.

A: Feijoa is certainly one of the easiest fruit trees to grow as it does not require much care. It is an attractive, evergreen tree or large shrub with dark green, oval, leathery leaves. It has an abundance of uses in the garden and produces lovely edible flowers and fruit! The fruit is eaten fresh, added to smoothies or fruit salad and is also commonly used to make delicious jams and wicked chutneys. Feijoa fruit go a long way in flavor.
This plant is drought tolerant and will grow in almost any soil type. It loves full sun or partial shade and is wind resistant. A lot of gardeners like to grow it as a wind barrier for this reason. It can easily be shaped into a dense, informal hedge or screen that needs very little pruning. Because of this density, it provides excellent shelter for all kinds of wildlife. Butterflies, birds, and butterflies will all love you for growing Feijoa!
Space the plant five feet apart to create a wind barrier hedge. Heat does no not bother it at all and it will also withstand temperatures to 10 degrees F.
The plant gets its names from the delicious perfume it emits. Some folks seem the fruit taste like pineapple, with a slight minty undertone. Others feel the flavor reminds them of juicy fruit gum! The texture is described as smooth and slightly gritty - almost like a pear, but firmer.
If you prefer to grow this plant as a tree rather than a large shrub, simply remove the lower branches up to one-third of the tree's height over a period of time. The Pineapple Guava can grow up to 15 feet wide and tall. They also do really well as a container plant on patios where you can truly enjoy the lovely fragrance of the fruit. It prefers rich, organic, well-drained soil and will need light fertilization every other month in most soils.

We recommend:

Fruit Festival Plant Food - Super Crop Booster
Mango-Food - Smart Release Fruit Tree Booster
SUNSHINE-Honey - Sugar booster
SUNSHINE C-Cibus - Crop Nutrition Booster

Pretty, pink, edible flowers will wow you from May to June, followed in late summer or fall by the delicious and fragrant fruit. An interesting thing about this fruit is that you don't pick it. It falls to the ground when it is ripe. Or simply place something under your tree, like a tarp, and shake the tree. The ripe fruit will fall off. You can store the fruit in your refrigerator for up to a week. And remember! The fruit of the Feijoa is not only a very rich source of soluble dietary fiber, but also an excellent source of Vitamin C, and very rich in antioxidants. They are also low in calories. Each fruit only holds 55 calories.

How to fertilize Caladiums and other Aroids

By Ed Jones, the Booster Guy

Q: I have a large collection of Aroid plants, different Monsteras, Philodendrons, and several unique varieties of Caladiums. I've been always told that Caladiums should not be fertilized, they don't like it. Is it so?

A: Caladium farmers often say that these plants don't need any additional fertilizer and that they really don't like it... The thing is, caladiums do not like DRY fertilizers, and this is why. Most Aroid plants do not like being watered too often, so dry fertilizers in combination with infrequent watering create excessive salinity for the root system. We have run some tests on the proper fertilizers for caladiums and the best results were performed after using SUNSHINE Robusta. It is amino acid based, so the delicate, large-leaved Aroid plants will not have to work quite so hard to take up the nutrients, and there will be no nutrient lock up in soil. The nutrients are readily available to these plants.
In this article, you will see some test results of caladiums fertilized with SUNSHINE Robusta vs. other brands of fertilizer, with more vigorous growth and larger leaf size occurring after use of Sunshine Robusta...

Caladiums do not have to be just an accent plant. They can also be the focus point of a garden area. It is said that as many as 98% of the world's caladium tubers come from right here in Highlands County, Florida, also home to the Sunshine Boosters manufacturing facility. It is such a big deal that they have a Caladium Festival here each summer. The fields are absolutely stunning in all of their colors. This year the festival runs this weekend, July 23 - July 25.

Healthy Heliconia Leaves?

Q: I purchased a heliconia from you a couple months ago. The new growth seems to be doing fairly well, however some of the larger leaves are discoloring around the edges then drying up. It's potted in a large pot with potting soil with 3 holes in the bottom to help with drainage in partial sun under a Royal Palm facing northwest. I'm here in Ft Myers. I was previously watering it every other day with your rapid growth fertilizer 1 tbsp per gallon but I have cut that back to once or twice a week. Please let me know your thoughts.

A: Heliconias and Gingers tend to develop dry leaves if grown in pots, especially ceramic or clay pots, because soil in such pots dries out too fast. These dry leaves are not caused by fertilizer, and you can see lots of new healthy green growth. The plant overall seem to be healthy. Continue fertilizing it with liquid Sunshine Robusta that is great for all wide-leaf tropical species, promotes green, lush foliage, and do not use any additional dry fertilizers!
Another suggestion, try to move the plant in more shady spot. Right now it sits in pretty bright light, this may be OK for established plants in the ground, but potted heliconias are very sensitive to hot sun. They get leaf burn easily.
