Dragon Fruit Magic Tricks

Q: I purchased two sweet red pitayas, that arrived and were planted on May 28, 2020, they were damaged but not serious. my question is this one pitaya is a beautiful green, and has grown 6or 8 "already, the other is bigger and is a grayish green and has not shown any sign of growth at all in six weeks, how long do I wait before I throw it out and buy another?

A: Being a cactus, sometimes Pitaya slows down its growth waiting for more favorable conditions. If one of your plants doesn't show any new growth, just give a it some more time and make sure the plant stays happy. To make pitaya happy, provide the following:
- Water. Unlike most cacti, Pitaya prefers regular watering (but not a wet soil). Make sure it is planted in well-drained media. Do not water again if soil remains moist, wait until it dries out on the surface. During hot weather, Pitaya enjoys light daily watering.
- Light. Unlike most cacti, Pitaya benefits from a filtered light especially while establishing. Try to create a temporary shade over the plant until it starts active growth (if grown in the ground), or move the pot in filtered light. Dull color or dry spots are signs of sun burn. Once the plant shows new growth, you may remove sun protection, or move the pot gradually into the full sun.
- Food. Pitayas are heavy feeders. Use the following fertilizer:
SUNSHINE C-Cibus - Crop Nutrition Booster

Q: I've been growing dragon fruit cuttings from Okinawa, Thailand and Vietnam for several years in pots and cannot get them to fruit. Any fertilizer suggestions? I live in Northern Virginia so I bring the massive pots in the garage under lights and a heater for the winter but back outside once the temperature warms up.

A: There is a little trick to get Dragon fruit to flowering and fruiting. This plant likes flowering when it is attached to a strong support. In commercial plantations, they use special trellises/frames made out of logs, but you can make one yourself using simple materials.
See article: Do-It-Yourself Support Structure for Dragon Fruit.
And of course, don't forget a special plant food for tropical fruit - Sunshine C-Cibus.
You can successfully get your Dragon fruits to fruit in pots, providing bright light in Summer. In Winter, keep the plants on a dry side to give them some rest and a chance to hibernate before the next fruiting season.

Curious Gardenia graft

Q: I was told to send you pictures of my hybrid gardenia tree. About 6 months ago the new growth on the top of one side became crinkled. It doesn't get straightened out either. It seems like it just stays like that until it falls off. Any ideas?

A: Your plant is not sick at all. This is what happened...
Your gardenia is a grafted variety. Gardenia varieties (Gardenia jasminoides hybrids) are grafted on rootstock of Gardenia thunbergia (this species is nematode-resistant and used for rootstock especially in Florida). The side branch that you call "crinkled" is actually the rootstock (Gardenia thunbergia) growing from UNDER the graft. Gardenia thunbergia has naturally "wavy" leaves.
If you follow this branch to its base, you will see where it starts - right below the graft. This happens very often.
You need to remove this branch altogether, from the point where it starts. It sucks energy from the plant and eventually may take over the whole plant.

Growing Stephanotis and cold protection

Q: I bought from you 3 plants Stephanotis How do I protect them from this low temperature now? I live in Ft Myers Beach.

A: In Ft Myers Beach, you have frost-free winters. You don't have to worry about cold protection for the Stephanotis. It is pretty cold hardy plant in spite of being a true tropical (it enjoys Hawaii environment for example). From our own experience, Stephanotis can even take a light frost for a short period of time without any damage.
You can keep this plant either in a pot or plant in the ground in a nice sunny location for more profuse flowering. It can climb a tree, a fence, or a pagoda.
However, keep in mind that during cool weather you need to reduce amount of watering. Wet + cold is a bad combination for plants. Water again only when the soil gets slightly dry. In summer time, extra water is not critical because it evaporates quickly with high temperatures.

Healthy Plants. Q&A from Mr Booster: Fertilizing Mango trees in Winter

Q: I'm living in Maryland growing zone 7A and would like some info on when to fertilize my potted mango trees. I ordered your Sunshine Mango Tango 2-2-4. All your mango trees are in pots.

A: You can start using this fertilizer right away, any time of the year, and every time you water your plants.
Sunshine Mango Tango, as well as other Sunshine boosters, is an amino-acid based liquid fertilizer that is scientifically developed for daily plant needs in all necessary nutrients. This means, you may use this fertilizer with every watering, including winter period.
Traditional fertilizers (both granulated and soluble, EDTA-chelated) can only be used during hot months while plants grow actively, and must be limited or not used at all during cooler months, to avoid nutrient lock up in soil (which basically means "building up unused elements"). With Liquid Sunshine Boosters, it is safe to add them every time you water your tree.
During cooler weather and when plant metabolism slows down, a tree will consume less water (as well as food), and you will automatically reduce watering, to keep over-wintering plants on a dry side. This means, less fertilizer too. This allows you to control elements intake naturally, like you control water amount just as much as the plant needs.

How to make Mango tree fruit

Q: Hello, I have a five-year-old Lemon Meringue tree that has only given me fruit one year. It put out about 50 mangoes and has done nothing for the past three years. Do you recommend any vitamins or any of the nutrients that you guys sell to help with this for next season?

A: We've had very similar problem with our Nam Doc Mai Mango tree, fruited once and no more next year. Usually the reason is nutrients deficiency, here in Florida we have poor soils. We applied Mango-Tango tree booster and it started flowering within a couple of weeks.
Generally, Mango flowering season is over by now, however, we recommend to feed the tree starting now, during active growth season. This way it will get better established before winter and also will store away all elements necessary for triggering flowering and fruiting. So by late Fall through Winter it will be ready to flower.
Along with the fertilizer, additional micro-element supplements will be beneficial. For improving fruit quality and increasing number of flowers, we also recommend to use SUNSHINE-Honey - sugar booster
