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.
Q: I have 5 avocados. Three of your cold hardy varieties and two
others that have all flowered and set fruit in the past. The last two years
including this year, not a single one of them has put out any flowers. I am
getting lots of new growth like one would expect on a tree too young to flower.
The last two years have been very mild with out any damaging frost where in
previous years they lost all their leaves due to frost yet started putting
out flowers once winter was over. I am confused because they have all flowered
and set fruit previous years. Any ideas would be appreciated.
A: From information you provided, and considering the trees get
lots of full sun and cold was not an issue, the only explanation is - lack of
nutrients. Here is an example.
Very common situation: you get a small 2-3 ft Avocado or Mango tree in 3
gal pot (or even smaller) from a nursery, full of flowers, and sometimes even a
small fruit. You bring it home, plant it in the ground or a bigger pot, it
looks happy and grows like crazy. Then next year - oops, no fruit, sometimes
not even flowers. What happened?
When the tree lived in a nursery, it was provided with all necessary
nutrients through the injector systems (continuous feed); or some nurseries may use
top dress smart release on regular schedule. Regardless of fertilizer type,
professional grower's set up delivers plant food non-stop, on regular basis, with balanced formulas. Plants are not only growing fast but also ready to produce, since nutrients are always available for a full growth cycle.
When you plant a tree in the ground (or larger pot), conditions change.
They may be beneficial for the plant: lots of room for roots to establish, hence
lots of vegetative growth. Even if you planted it using good quality fertile
soil, this soil may contain mostly nutrients responsible for vegetative
growth (branches and leaves). Chances are, your soil may be rich in Nitrogen
(good for green growth), but poor in other elements responsible for flowering and
fruiting (Phosphorous, Potassium, and many important micro-elements such as
Molybdenum, Boron, Iron, etc.). Besides, existing soil gets exhausted
quickly, and within a year a two, if you don't add fertilizer, flowering and fruiting may be reduced or even stopped.
This is why fertilizing program is very important for fruit trees that are expected to bring a crop soon.
Also keep in mind that some fruit trees have a habit of "skipping" a year and may either produce less or not produce at all every other year. In any case, balanced nutrition program can help to fix this "bad habit".
Q: Hi, I purchased ylang ylang tree a couple of years ago. It's grown quite well in my Greenhouse but I'm having some trouble figuring out if I'm watering it too much not enough or if it has an insect. Can you please take a look at my photos and maybe give me a suggestion of what my problem might be?
A: It is normal for Ylang Ylang tree to get dark spots during
winter time. Sometimes Cananga gets whole branches darkened (especially dwarf variety fruiticosa), some may even fall off. But they will be replaced
with new growth in Spring-Summer. There is nothing wrong with your plant, it is
just a reaction to cold and short day light when you keep this plant indoors. These leaves eventually will fall
off as the weather warms up, and will be replaced with a new fresh green growth.
Luckily, Cananga is not susceptible to insects and diseases, but its leaves
can look unattractive in winter.
Make sure to keep watering at minimum until temperatures raise to 80's.
Start fertilizing as soon as new growth appears. We recommend SUNSHINE Pikake
- Fragrant Flower Booster, an ultimate fertilizer for fragrant plants.
Q: My Red Jade Vine has the leaf tips turning brown. I water this plant four
times a week and I am using a half a teaspoon of miracle grow bloom booster
15-30-15 per 2 gallons, every two weeks. In the beginning I had to water this
plant off city water in South Fort Myers. Over the last two months I picked
up a dechlorinator buggy plus threw that on my hose and I've been watering it
with that but it didn't seem to make a difference. I put this plant in the
ground last September. It has three shoots that run into the top of the tree,
so it is growing but leaves seem to drop off down low at the base of the vine
and the brown tipping running into the top of the plant. But not the newest
shoot its leaves are solid green all the way at the top. Thanks for any
advice.
A: Mucuna benettii - Red Jade vine - is not the easiest plant to grow, and
we are glad your vine is growing well. For those who love this plant but not
ready to face all challenges, we recommend its cousin - Camptosema grandiflora - Dwarf Red Jade Vine, which is much hardier and
easier plant.
We looked at the photos and these are our thoughts.
1) The top of the plant with green fresh leaves definitely indicates
that the plant is generally healthy and vigorous.
2) Dry tips of the old leaves may indicate excess salts in soil, in
combination with the summer heat that it went through. Based on your feeding program
description, that fertilizer may create a problem. Water soluble traditional
fertilizers are EDTA-chelated which often causes nutrients lock up in soil
and leaf drop. Try to stay away from that fertilizer for a month and let the
rains and/or irrigation water flush the soil for a couple of weeks.
3) Red Jade vine is a very sensitive species. Normally, during hot season
it is safe to use traditional fertilizers, especially slow-release granulated.
However, with this plant we recommend you to switch to more delicate formula
and use only liquid fertilizer. SUNSHINE Megaflor - Bloom Nutrition Booster will be the best. It is
safe to use it as frequent as with every watering! It is amino-acid
based, and will be totally consumed by the plant without nutrient lockup.
4) Another cause of dry leaf tips may be micro-element deficiency.
Megaflor booster already has all necessary micro-nutrients in it, plus you
may apply some extra: SUNSHINE Superfood.
5) You may continue using regular water for watering (including city water)
as long as you use amino-acid based plant food and supplements: they improve
soil acidity (what tropical plants like is acidic soil, and Florida soils
are alkaline). Additionally, to improve soil acidity which can be critical for
this Mucuna species, you may add 1"layer of pure peat moss on top of the
soil around the plant. Please keep us in loop how the plant is doing. It is
pretty rare species in cultivation and we will be happy to help you to keep it
thriving.

Growing Stephanotis and cold protection
Q: I bought from you 3 plantsStephanotis 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.
