Healthy Plants: Q&A from Mr Booster

How not to kill gardenias?

Q: I have tried to grow gardenia in pots for years and never keep them alive. When i look on camellia websites they say fertilize potted plants twice a year. I'm confused as I tend to kill them with kindness haha. Also, if our tap water has high cal/mag and that stops the gardenia getting other nutrients why would I make up the feed with tap water? So confusing and online is mixed messages...

A: Gardenias are not the easiest plants to grow, however, they are easier in pots than in the ground: they prefer acidic soils, and in many areas soils are alkaline. The most important factor is balanced and sufficient nutrients. In the ground, plants have no limits to reach out to different elements by spreading their root system. In a pot, once all the good stuff is consumed, plants start suffering nutrient deficiency. This is why a balanced feeding program is important.

Generally speaking, Cal/Mag in tap water cannot be bad, because they are essential elements, good for plants (in proper amounts). However, just Cal/Mag is not enough. This is why you need a balanced liquid fertilizer for plants that prefer acidic soil. Excessive Cal/Mag alone can create nutrient lock up, especially if they are chelated with EDTA like in dry fertilizers, which are not fully accessible for plants.
We recommend natural, Amino-Acid based fertilizers that are completely consumed by a plant and are safe to use with EVERY watering, even in Winter. They are scientifically formulated and cover all plant needs. For your gardenias, you should use SUNSHINE Pikake - Fragrant Flower Booster.
Another important factor is proper watering. Gardenias like regular water but don't like wet feet = well drained potting mix is a must, similar to Abundance professional growing mix.

What are the most rare fruit trees?

Q: What is the rarest and unusual plant that you have? I want something special for my tropical fruit tree collection. I already have everything I could possibly get...

A: Are you sure you have everything? Check out our rare plant section, and look at these couple plants we just received... these won't last long, we have only a few!

Quararibea cordata - Zapote Chupachupa, South American Sapote (with express shipping)

Chupa-chupa, Zapote, South American Sapote... One of the most amazing and showy tropical fruit trees with huge heart-shaped leaves, heart-shaped fruit, and fast-growing habit. The fruit has a bizarre shape like a large breast with a nipple, and the pulp is very tasty. For best performance, the tree needs full sun, rich soil, plenty of moisture and fertilizer.

Garcinia mangostana - Mangosteen

Mangosteen... This delicious fruit has a thick, dark-red skin, inside which are creamy-white segments with a sweet, slightly tart flavor. Purported by many who have had the luxury of tasting it as being the best tasting fruit in the world.

Fruit tree size and production

Q: I am interested in a Strawberry Tree... does this tree produce fruit while still small or do I have to wait until it is large before it produces? Should I fertilize it so it produces sooner? I ask because my garden is not large and I prefer to keep my fruit growing trees in a smaller size. Also, how big is the fruit and does it have a seed?

A: Strawberry Tree, Muntingia Calabura, is one of those fascinating fruit trees that starts flowering and fruiting in small size. We have plants growing in 1 gal containers that already have flowers. This tree is nearly year-round producer providing warm conditions. It is a fast grower, although a compact tree when mature, and can be trimmed to desirable size without affecting production.
Muntingia fruit is one of our favorites. It is super sweet and juicy, and the seeds are tiny small, not bigger than the strawberry seeds, so you don't have to spit them out. The fruit size normally about 1/2 inch, but we have a tree in our garden that produces almost cherry-size fruit! See picture above. The secret is, good watering and using fruit booster - SUNSHINE honey micro-element supplement. We also fertilize our fruit trees using Fruit Festival and Mango-Food fertilizers.
