EASY GROW-BOX

How to quickly germinate tropical seeds in winter

By Mark Hooten, the Garden Doc

Q: I live in the New England area where the winters are very long and dreary. I plant both a veggie and flower garden during the warmer seasons and am especially fond of growing chili-peppers. On account of most chili's longer growing seasons, I need to get already established plants in the ground as soon as the weather is warm enough. My problem is that despite my best attempts to germinate and grow seedlings ahead of time - even in my sunniest window - I just can't seem to keep the soil evenly warm enough to get them to germinate, no matter how warm the room is kept. And on the occasion they do come up, the seedlings always seem to remain weak and stunted, likely owing to the especially low humidity of winter. I also tried using an electric seed-starting heating pad, and the results were only a little better. Are there any tips you could give me?

A: Yes, I understand your issues and can sympathize! While it might be surprising to some, even here in sunny S.W. Florida, there are long stretches of winter weather where the ambient temperatures are simply too cold for germinating many of the more tropical seeds, such as the notoriously warm-weather chili-peppers. Also, I am likewise a fan of chilis, and always have at least a few different kinds growing at any given time. I have two great suggestions...

Plumeria cold protection

Q: We have a purple-flowering plumeria which resides on our sunny deck during the warm months and then Winter vacations on our back porch where we can close the plastic film windows and where it stays above 50 degrees (overnite) until it can get moved outside again. We live in zone 8+ in South Carolina and I would love to plant it outside. Do you think if we ghost-covered it when alerted that we would have an overnite freeze, that it would survive being planted in the ground and recover to flower when warm? I don't believe the soil in our yard has ever frozen below the top 1/2 inch or so, and never for more than a few hours at a time. What do you think?

A: Plumerias are tropical plants, which means, they need frost-free environment. Even if the ground is frozen only on "the top ½" or so" - this may be enough to kill the plant. From our experience, plumerias can withstand a few hours of windchill frost (not frozen soil), but even if they survive, they may get some branches damage, and recovery may take so long that the plant may not even bloom the next year. So I wouldn't take that risk even with a ghost-cover cold protection. We have customers who grow tropical plants in the ground in colder areas, but they have greenhouse protection: this means, the soil is warm and the air temperature is maintained above 45-50F. For example, this Greenhouse in Virginia.

We recommend to continue growing your rare plumeria in container and move it inside when temperatures drop below 50F (recommended) and for sure when they drop below freezing. Plumeria can take a cold night (a few hours of upper 30's) as long as it is followed by a nice warm sunny afternoon with at least upper 50s. Otherwise, keep it indoors. The good news is, since plumerias are deciduous and have no leaves in winter, low light level won't affect the plant.
Just make sure to minimize watering and keep the plant on a dry side until it starts growing new leaves in Spring. You may continue fertilizing once a week with half-doze of Sunshine boosters - Sunshine TotalFeed. This will maintain the plant healthy and prepare for the blooming season in Spring.

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.

When to apply super boost?

Sunshine Boosters: a breakthrough in Winter fertilizing

In the photo: plants are tough survivors. Life can't be stopped even by a brick road!

Q: Just wanted to know best time of day to apply super boost as spray and watering? Only listed to make sure night temp doesn't drop below 65F...

A: As a rule of thumb, plant's needs in fertilizers are very low in the cold season because they consume less nutrients during dormancy. For tropical plants, when minimum temperatures drop below 65F - we stop applications of dry (granulated) fertilizers until spring, to avoid root burn.
Liquid Sunshine Boosters are exceptions from this rule to a certain extent, for 2 reasons:
- they are amino-acid based which means, salts do not build up in the soil, and thus will not burn the roots even with slower plant metabolism.
- concentrations/formulas are mild and designed for as frequent as daily watering

1) When a plant goes into full dormancy (drops leaves and does not show any new growth), you may stop fertilizing with any Macro NPK products (both dry and liquid)

2) If a plant is evergreen and continues growing during the cooler period, and especially if it is a winter bloomer, mild liquid fertilizers can be applied, depending on the stage of plant development.
Robusta and TotalFeed are used for vegetative growth and pre-flower.
Megaflor and C-Cibus are used for winter flowering/ fruiting plants during the bloom stage.

See full list of liquid boosters

3) Micro-elements can be used all year round for all plants that are not dormant (do not drop leaves)

4) Always use Sunshine-Epi as a foliar spray to activate immune system and unlock protective mechanisms, BEFORE applying other boosters. It is especially important during Fall-Winter for improving cold tolerance and disease resistance.

5) Always apply foliar spray and/or drench the soil with solutions in morning hours so the plant has time to process the nutrients during daylight when metabolism is the most active.

6) Avoid any dry fertilizers during winter

Saving Fallen Papaya Tree

Q: Hope there is help for my beautiful amazing papaya tree! There where a loooooooot of fruits on it, but it broke! First of all, it was leaning and friends tried to straight my beautiful tree. What can I do? Will it get fruits again?

A: A couple months ago we also had a Papaya tree loaded with fruit that fell down (see photos). It was heart-breaking. We secured it and it continued growing for a couple of weeks but unfortunately, at the end the tree still died, leaving us a million fruit. The Papaya tree has a very sensitive root system and is hard to re-establish once the roots are damaged.
However, if it just has a broken top, it has a good chance to grow back from the side shoots.
Of course, remove all the fruit so they don't take energy from the recovering tree.
When a tree is loaded with fruit, it is important to provide support for heavy branches and for the trunk if needed. Always support the fruiting tree to prevent from possible falling BEFORE it starts leaning down and may become broken by even a light wind.
In the photo, you can see how we fixed boards around, but it was already after the tree fell. Unfortunately, it was too late since the roots got damaged. Always need to stake the tree up before the branches get too heavy!

Only local pick up from our Garden Center
Hurry up, while supply lasts!

Hardy Plumeria Pudica

Q: I have ordered plumeria pudica from you in March and it is thriving really well here in Rancho Cordova, California. The current temperatures are ranging from 68 to 32 degrees Fahrenheit. My USDA zone is 9b. Does this plumeria pudica survive outside with temperatures dropping in coming winter in CA?

A: From our experience, Plumeria pudica is pretty cold hardy and takes some cold spells in spite of being a tropical species.
Our trees (well-established) took a few hours of freeze with no significant damage.
Potted plants are less hardy than in-ground plants. However, their advantage is, they are easy to move indoors or inside warmer place like garage, etc. If the temperature stays borderline around 32F for a few hours, the plant should be safe as long as warm day temperatures follow a cold night. For longer periods of cold, move the plant inside.
Make sure do not overwater and keep Plumeria on a dry side during winter, since cold and wet is a bad combination and may cause root problems.
Above is the picture of Plumeria pudica tree growing in Cape Coral, FL where low temperatures in winter sometimes go down to upper 20's for a few hours.

To improve cold hardiness of Plumerias and other tropical plants, use SUNSHINE-Epi-T for plant thermal protection and immune system boost.
Make sure to fertilize plants on regular basis to keep them strong and vigorous. The stronger and bigger the plant, the hardier it is!

Best tasting white guava

Q: What's your best tasting white guava?

A: Our favorite white Guava is Viet Nam variety that is also very rare and hard to find. The fruit is very large, up to 6" in diameter, the pulp is very sweet and somewhat crunchy. The seeds are small which makes it more pleasurable to eat out of hand.
Another great feature of this variety, it stays compact and branches do not get leggy, unlike most guavas. It can be easily grown in a container, trimmed to the desired size and it will produce fruit under proper care.

Another cool variety is Indonesian, it also has a large round fruit and very few seeds to compare with others.

And last but not least, if you prefer soft fruit to crunchy, the Peruvian variety is a great choice. The fruit is pear-shaped.

Remember to provide plant food for good production, especially if grown in a container.

Using SUNSHINE Complete Nutrition System

For hydroponics and potted plants

Q: I recently bought both the 5ml of the sunshine epi and the 100 ml advanced nutrition kit. I read on the paper for the Epi not to use any other strong fertilizers along with this but I was wondering if it'd be alright to use both this foliar spray and nutrition watering together?

A: All solutions in SUNSHINE Booster Nutrition System (NPK-macro and micro-boosters) are compatible.
The only exception is Sunshine-Epi - brassinosteroid bio-stimulant. Epi should be mixed with distilled water separately from other boosters. The reason is, it is very bio-active, and if mixed with other compounds, oxidizes quickly which may affect its performance.

Sunshine-Epi solution must be prepared using distilled water and applied as foliar spray only (it only works on contact with leaves and not through the root system). Epi shows extremely impressive results when you apply it before the application of other nutrients because it increases plant metabolism; so all boosters become even more effective if you spray Epi the day before.

When using Micro- and Macro-boosters, you may mix all components in one watering can/tank (except for Epi), using regular tap water. Besides watering root ball, the macro-micro solution can be also used for foliar spray. It is optional, as in some circumstances growers prefer to keep leaves dry at all times: to stay away from mold, fungus and other issues caused by the wet environment.

Here is an example of Sunshine Boosters Nutrition System application:

Daily watering in one can: NPK 25 ml/gal (one of 5, depending on growth stage) + Constanta 5 ml/gal + Ca-Support 5 ml/gal, mixed in tap water
Every 2 weeks: spray Sunshine-Epi 2.5 ml/gal - to boost the immune system and growth rate, mixed in distilled water
From daily to every 2 weeks: Sunshine-Power-Si 25 ml/gal to protect from diseases and keep pH at 5.5-6.5. Can be used as often as daily and mixed with a daily watering solution (1)
As needed: Sunshine SuperFood and GreenLeaf - for correcting deficiencies. Can be also mixed with the daily solution (1)

Make sure to prepare a solution right before use and do not store solution for more than 1 day. Keep concentrates and solutions protected from bright sunlight.

Here is also advanced information on Sunshine Boosters compatibility.

Fertilizing in Winter?

Q: I'm a bit confused about what winter fertilization schedule I should follow in South Florida. For blooming plants, usually, I use a monthly granular bloom booster fertilizer as well as a liquid fertilizer every 10 days or so. Should I continue that schedule in the winter as well? Should I stop fertilizing altogether in the winter? How about fruit trees? What fertilization schedule should I follow in the winter?

A: Here is a general fertilizing schedule for established plants that we follow here in SW Florida.
The rule of thumb is, do not fertilize (with macro- NPK elements) when minimum temperatures drop below 65F and stay at that level for more than 7 days. At this temperature point, most of the tropical and subtropical plants slow down their metabolism and some of them going into dormancy. This means, nutrients are not consumed as much as during active growth period, and built-up nutrient supply within a plant plus whatever is available in the soil is just enough to get by through the winter. So additional fertilizing is not necessary. You may continue micro-element supplements and bio-stimulants throughout the year. In fact, it is highly recommended to do so, to help the plant survive cold spells. These are very effective tropical plant protectors:
SUNSHINE-Epi - Brassinosteroid plant hormone
SUNSHINE-Power-Si - Advanced plant protector with Silicon
SUNSHINE SuperFood - Complex microelement supplement

This rule is applied to both flowering and fruiting plants, in general. However, some species are winter-flowering and winter-fruiting. For those, you can make an exception and provide extra nutrients for flowering and fruiting, as long as the weather stays warm. During cold spells, avoid any NPK fertilizers and use only bio-stimulants and micro-elements. If you apply NPK during cold, it won't be consumed by a plant, build up in the soil, and may create a root burn situation.

In simple words, fertilize from March to October. Give plants some rest from November to February.

Gardenia flowers: how to prevent bud-drop

Q: My gardenia looks beautiful, but the flowers fall off of it before they even open up, the majority of them get this brown color at their base. Can you point me in the right direction.

A: There are 3 possible problems, either one, or a combination:

Lack of light
Too much water
Lack of micro-nutrients in soil

Try the following treatments:
- micro-elements SUNSHINE-SuperFood as foliar spray + drench rootball, once a month, it will improve quality of the flowers.
- Silicon protection: SUNSHINE-Power-Si. This supplement has Silicon as an active element (Si). Adding it to soil or/and over foliar spray can immensely enhance plants' resistance to external factors and boost their growth and health.
Make sure the soil is not soggy, reduce watering especially during fall/winter.
