Cactus and succulent garden and greenhouses | Bob Barth | Central Texas Gardener

December 6, 2019


>>BOB BARTH IS AN EXPLORER.
HE VENTURES BEYOND THE BORDERS WITH PLANTS THAT UNITE OUR GLOBAL COMMUNITY TO DISCOVER
THEIR PURPOSE AND APPRECIATE THEIR BEAUTY. ON HIS HILLSIDE PROPERTY SHARED WITH PARTNER
NOREEN, HE GROWS COLD HARDY CACTI AND SUCCULENTS IN THE GROUND.
OTHERS RESIDE IN GREENHOUSES WHERE HE GROWS AND PROP GATES PLANTS CHOSEN FROM WHOLESALE
NURSERIES. HIS A PASSION IS TO PROPAGATE AND PRESERVE
PLANTS AND HABITAT, AN INTEREST THAT PROPAGATED WHEN HE WAS A BIOLOGY PROFESSOR AT THE UNIVERSITY
OF TEXAS.>>BACK IN THE EARLY ’70’S THEY WERE DOING
A SERIES OF INFORMAL CLASSES AT U.T., AND ONE OF THEM WAS ON CACTI AND SUCCULENTS.
AND I HAD I THINK JUST BEFORE THAT PICKED UP A FEW CACTI AT LOCAL NURSERIES AND THOUGHT
THEIR SHAPES AND TEXTURES WERE REALLY INTERESTING.>>MEETING LIKE MINDED GARDENERS, THEY FORMED
THE AUSTIN CACTUS AND SUCCULENT SOCIETY TO EDUCATE THEMSELVES AND OTHERS THROUGH MEETINGS,
ONLINE AND SEMI ANNUAL SALES, THEY FOSTERED ENTHUSIASM THAT CONTINUES TO GROW.
>>MAYBE IN PART BECAUSE OUR CLIMATE SEEMS TO BE DRYING OUT, THAT CACTI AND SUCCULENTS
HAVE BECOME MUCH MORE POPULAR, THERE’S A LOT MORE VARIETIES AVAILABLE NOW WHICH ARE ACTUALLY
REASONABLY COLD HARDY AND CAN BE GROWN INSIDE. WHEN I FIRST STARTED THIS LITTLE GARDEN ALONG
MY DRIVEWAY, YOU COULD GET SO TALLS, AGAVE AND OTHER THINGS, BUT SINCE THAT TIME SO MANY
OTHER POSSIBILITIES ARE NOW AVAILABLE.>>AS A BIOLOGIST BOB WANTED TO KNOW MORE.
IN A WIRE CAGE GREENHOUSE HE STUDIES PLANTS LIKE ALOES.
>>ALOES ARE NATIVE TO SOUTHERN AND EAST AFRICA AND ALSO THE ARABIAN PENINSULA AND THE ISLAND
OF MADAGASCAR. WHAT WE’RE LOOKING AT HERE MAINLY ARE HYBRIDS.
>>CALIFORNIA GROWERS HAVE HYBRIDIZED VARIETIES WITH INTRIGUING COLORS AND TEXTURES.
ALOES WANT GOOD SUNLIGHT AND DRY SOIL. IN SOUTH AFRICA THEY ARE GARDEN PLANTS, BUT
MOST NEED PROTECTION FROM HARSH WINTER COLD IN TEXAS.
>>IN SOUTHERN CALIFORNIA AND AROUND HERE WHEN YOU HAVE ALOES BLOOMING THEY WILL BE
ADMITTED BY HUMMINGBIRDS.>>HEALTHED TO ALOE IS HAWORTHIA.
>>THEY ARE ALL FROM SOUTH AFRICA. SOME ARE HYBRID OR NATIVE SPECIES FROM SOUTH
AFRICA. THEY COLOR UP NICELY WITH A BIT OF SUN.
THE NICE THING ABOUT THIS PARTICULAR FACILITY IS IT GETS SUN IN THE MORNING AND IT’S SHADED
BY MARCH IN THE AFTERNOON. IN HABITAT THEY TEND TO GROW UNDER A SEMI
DESERT SHRUBS AND THINGS LIKE THAT.>>COLD TENDERED PLANTS MOVE TO A TEMPERATURE
CONTROLLED GREENHOUSE IN WINTER WHERE BOB GROWS PLANTS YEAR ROUND.
FROM TALL TO TINY HE GROWS MULTIPLE GENERA OF SUCCULENTS AND CACTI.
HE REPRESENTS NEW WORLD PLANTS LIKE CACTI AND AGAVES.
FROM THE OLD WORLD HAWORTHIAS, ALOES AND SUCCULENT EUPHORBIAS.
ANOTHER GREENHOUSE SITS ATOP THE CARPORT, AN IDEA FROM ONE OF HIS GRAD STUDENTS TO GET
THE SUNNIEST SPOT FOR CACTI AND OTHERS. HIS FASCINATION WITH THESE DISTINCTIVE PLANTS?
>>IT HAS TO DO WITH THEIR UNUSUAL SHAPES, UNUSUAL COLORS, TEXTURES AND SO FORTH.
>>SOME OF THEM ARE ASTROPHYTUM.>>IT’S A SMALL GENUS OF CACTI, THERE ARE
ONLY ABOUT A HALF DOZEN SPECIES BUT THERE ARE GOOD SUBJECTS FOR HYBRIDIZATION, AND THE
THING SO INTERESTING ABOUT THE ASTROPHYTUMS SOME OF THEM ARE TOTALLY SPINELESS.
OTHERS HAVE A FEW SPINES, BUT THEY HAVE INTERESTING PATTERNS OF WHITE MARKINGS ON THE SURFACE
OF THE PLANT. AND IF YOU MAKE HYBRIDS YOU CAN GET ALL KINDS
OF REALLY INTERESTING PATTERNS.>>THE MELOCACTUS ARE JUST AS DISTINCTIVE.
IN HABITAT THEIR FLOWERS ARE POLLINATED BY HUMMINGBIRDS.
>>IT’S A GENUS OF CACTI THAT IS FOUND IN SEMI AIR RID AREAS IN THE TROPICS.
A LOT OF SPECIES IN BRAZIL. AND BASICALLY IT’S A TYPE OF CACTUS THAT LIVES
FOR AWHILE AS A VEGETATIVE, TYPICAL LOOKING CACTUS, BUT WHEN IT DECIDES THAT IT’S MATURE
IT STOPS THE NORMAL VEGETATIVE GROWTH AND PUTS ON THIS BRISTLY STRUCTURE ON THE TOP
OF IT CALLED A CEPHALIUM. AND OUT OF THAT BRISTLY STRUCTURE WILL COME
THE LITTLE PINK FLOWERS AND THEN THE LITTLE PINK FLOWERS
TO G.O.P. EARLIER.
>>OTHERS THAT WOULD GROW UNDER SHRUBS AND HABITAT EXPOSE MORE OF THE FOR PHOTOSYNTHESIS.
COLORATION ON SOME ECHEVERIA PROTECTS THEM FROM ULTRAVIOLET LIGHT.
>>IT’S A WHITE POWDERY SUBSTANCE THAT THE PLANT PRODUCES.
AS IT DEVELOPS ITS LEAVES. THE POWDER IS ONLY GENERATE THE AS THE PLANT
IS DEVELOPING AND ONCE IT’S DEVELOPED IT WON’T PRODUCE ANY MORE POWDER.
>>BOB GROWS HIS IN THE WIRE CAGED GREENHOUSE. A HOME GARDENER CAN JUST PROVIDE MORNING SUN.
>>BECAUSE THEY DO NEED THE SUN TO KEEP THEM FROM ETIOLATING, TO KEEP THEM FROM GETTING
LEGGY AND COLORS ON THE LEAVES. MOST OF THE ECHEVERIA COME FROM ISLANDS IN
MEXICO WHICH MAKES THEM A LITTLE TOUGH TO GROW HERE IN TEXAS BECAUSE IT’S SO HOT IN
THE SUMMERTIME.>>SUCCULENTS BY THEIR VERY NAME HAVE DEVELOPED
STRATEGIES TO STORE WATER WHEN ITS SCARCE. CACTI AND MOST OF THE EUPHORBIAS STORE IT
IN THEIR STEMS. ECHEVERIA STORE IT IN THEIR LEAVES AND OTHERS
IN A BALL SHAPED STRUCTURE CALLED THE CAUDEX. SOME STRATEGIZE TO RISE THE NEXT GENERATION.
>>LILY TOPS ARE A GENERAL US OF PLANT FOUND IN NAMIBIA AND THEY HAVE AN INTERESTING GROWTH
CYCLE. THEY CONSIST OF TWO LEAVES FUSED TOGETHER
WITH A CRACK BETWEEN THE TWO. AND IN THE FALL OF THE YEAR FOR US, WHEN WE
GROW THEM IN CULTIVATION, THE FLOWER BUD COMES OUT OF THAT CRACK BETWEEN THE TWO LEAVES.
A NEW PLANT STARTS DEVELOPING INSIDE THE OLD ONE, SPLITS THE OLD ONE OPEN AND GRADUALLY
SUCKS ALL THE MOISTURE OUT OF THE OLD PLANT.>>SPINES MULTITASK.
>>SPINATION CAN HAVE A VARIETY OF DIFFERENT FUNCTIONS.
OF COURSE, IT CAN PROTECT THE PLANT FROM HERBIVORES BECAUSE IT’S NOT SO PLEASANT FOR AN ANIMAL
TO TRY TO EAT BECAUSE THEIR SPINY. THE SPINES CAN ALSO SHADE THE PLANT AND THEY CAN ALSO
SERVE TO COLLECT MOISTURE WHICH THEN CAN DRIP DOWN AROUND THE BASE OF THE PLANT.
AND THEN THE ROOTS GET ACCESS TO THE MOISTURE.>>IN HIS GREENHOUSES BOB CAN PROTECT FROM
TOO MUCH WATER LIKE FLOODING RAINS. BUT SUCCULENTS DO NEED MOISTURE.
IN SPRING AND FALL, HE WATERS EVERY COUPLE OF WEEKS.
IN SUMMER OFTEN ONCE A WEEK. IN WINTER IT’S MONTHLY OR EVERY SIX WEEKS
DEPENDING ON SUNLIGHT.>>ALONG WITH PROMOTING GARDEN WATER CONSERVATION,
BOB’S GLOBAL CONNECTION TO PLANTS AND THE WILDLIFE THAT DEPENDS ON THEM IS SIGNIFICANT.
>>I THINK IT HELPS US TO REALIZE HOW IMPORTANT IT IS TO PRESERVE HABITATS AND PRESERVE SPECIES,
MUCH AS WE CAN. MADAGASCAR IS A CASE IN POINT BECAUSE A VERY
HIGH PERCENTAGE OF PLANTS AND ANIMALS THAT OCCUR IN MADAGASCAR ARE FOUND NOWHERE ELSE
IN THE FOUND, WHICH IS IMPORTANT TO TRY THIS TO TRY TO SAVE SOME OF THE HABITAT.
THERE ARE AT OF CONSERVATION ORGANIZATIONS THESE DAYS THAT ARE WORKING IN THAT DIRECTION.
I THINK WE’RE MAKING SOME PROGRESS.

    One of the best videos on youtube! Question: I've always wondered, what type of machines do you use to generate heat and moisture? Can you explain the use of fans?

    I have just recently became a fan of succulents and cacti, like only since a year ago. I am fascinated by how sturdy they are and they are literally the only plants that I can keep alive…..

    Geez they did not develop God made them the way they are. They pro create after their kind are ya idiots have you ever seen a cactus have baby pine trees. Every farmer on earth knows when he plants corn heโ€™s going to get corn never has that not happened wake the fuck up.
