How do I make sure the plants in my garden
are safe for kids and pets?
Well, that depends on how dumb your kids and pets are.
My name is Carlos Campos Morera.
I am a landscape designer at Geoponica in Los Angeles,
and I'm going to answer some of your landscape
and garden questions.
This is Uncle Johnny,
who taught me everything I know about landscaping
and who I worked for every summer since I was 14.
He is going to be helping me answer some questions today
and hopefully not getting in any arguments.
All right, let's see.
How do I make sure the plants in my garden
are safe for kids and pets?
Oh, everyone asks this question.
If you Google it,
90% of plant material is poisonous to someone somewhere.
I wouldn't go down that hole,
but stuff like cycads, sago palms,
that group of plants is toxic to kids and pets.
It has a neurotoxin in its seeds and leaves,
and unless you're on the more risque side, I would avoid.
Also, stuff from the Datura family is pretty poisonous,
although some people grind it up and smoke it,
so, you know, to each their own.
So they have like these trumpet-shaped flowers
on the tree form.
The Datura rightii is a native
which has white trumpet flowers
that come out from a low-spreading bush.
It's one petal around the stamen
as opposed to like a daisy,
which is a composite and has many, many petals.
A lot of the time,
it's about the spikiness of plants as well.
There's a whole class of cactus called a puntia,
which are like the paddle cactus,
which, from a distance,
look like they're the most demure of all the cactus
because they don't have long spines,
but they do have something called glochids,
which are like tiny hair-like spines in bunches
that are the worst spines of all
because they just get into your skin.
They're so small,
you can't even get them out with like a tweezer.
What's the easiest thing to grow in a garden?
Weeds.
Do I need to use different soil for different plants?
Hell yeah.
Let me get some soil samples.
Where does this plant come from
and what is the soil type that it requires?
In a sort of basic sense,
there's plants that grow in tropical conditions
where most of the soil is composed of organic matter.
Leaves that fall to the floor decompose into soil,
and so if the plants that you were planting
were coming from those areas,
you would want to plant something like this
that has a lot more organic material in it
and it looks like classic soil.
Dark and rich.
A gradation down from that is,
and there's gradations in between all of this,
so I'm just showing you the big steps.
A drier environment
where there's a lot more minerals in the soils.
There's a combination of leaves decomposing,
there's sand and there's rocks that are decomposing as well.
So here you see different size rock material
and then there's also a little bit of organic matter,
so like it'll increase drainage.
Plants from those areas,
they don't like to sit in water for a long time.
They're not accustomed to it.
Because there's rocks in the ground,
the water goes in.
Some of it hangs around,
but a lot of it drains right through the rocks.
And then on the extreme ends of things,
that would be something like planting in pure pumice,
which is a rock that retains a little bit of moisture,
but there's almost no organic material in it.
So plants that come from hyper-arid conditions,
you'd wanna plant with something like that.
But then you can sort of use soil
to augment your conditions.
For example, if I was planting a succulent garden
in Florida and these succulents took this middle type
of soil that has some organic material
and some rock material,
but I'm planting it in a place like Florida
that's hyper, hyper wet,
then I would maybe use the soil
that is a hundred percent rock material
to offset the amount of water that is being introduced.
The size of the roots of plants will typically tell you
how coarse the soil is that that plant is accustomed to.
If a plant has super fine roots,
they're very thin and delicate.
That means that the soil substrate, where they come from,
is a much more delicate, fine soil.
If you plant it in here, you know,
in this thick rock substrate,
there's gonna be lots of air gaps in there
and they're not gonna be able to find their way to moisture.
And then conversely, if your plant,
take it out of the container
and it's got like super beefy jumbo roots,
that means that plant is used to much larger substrate.
You don't wanna plant with super fine soil
because that could suffocate those roots.
They're not used to that amount of density.
Does talking to my plants actually do anything?
Yes and no.
I don't think they understand what you're saying,
but maybe they can sense it.
But more importantly, it's about a relationship
that you're cultivating with this thing
and you're looking at it and regarding it as a living being.
And that type of respect and attention
makes you a better caretaker of a plant.
How to integrate a playground seamlessly into a backyard.
This is a good question.
Aesthetically, I don't, I can't say,
I don't know what your backyard looks like.
You can approach it more philosophically.
The three things that I typically think about is,
one is watching how kids play.
Take kids into nature and watch
how they traverse the landscape,
what they find interesting,
how they use the topography of the place
and take your cues from that.
The second thing I usually do is look at the playgrounds
from the 1950s and the 1960s.
In that golden age of playground,
they were getting artists like Isamu Noguchi
or scientists or engineers like Buckminster Fuller
to design playgrounds.
Aesthetically, they were being designed by artists
and engineers and thinkers.
So that automatically creates something
that's like visually interesting,
whether it was a study of geometric forms in the universe
or the way children interact with space
or with the textures of stone and masonry.
It almost doesn't matter
if it matches aesthetically to your house or not.
The thought behind it shines through
and they become interesting things onto themselves.
The third thing I like to think about,
how does this playground grow with the child?
Hyperspecificity has such a short shelf life.
Whereas a simple mound with a hole
that you can go inside of it
could be a cave for a three-year-old
or it could be an imaginary horse corral for a nine-year-old
or it's a place to escape your annoying parents
and gossip as a 16-year-old.
Are there plants I can be using
to help protect my home from wildfires?
Yes-ish.
It's a combination of things.
One important thing is how well irrigated your plants are.
So this is, I guess,
a little bit of a catch-22s in California.
The more that you water it,
the greener and lusher the plants are,
the less it becomes a fire hazard.
The other element to consider is breaks
so that the landscape is not a solid sea of plants
right up to the house,
that there's moments where there's hardscape
intersecting the planting
so that a ground fire can't spread completely.
A bunch of trees that are all,
their canopies are all touching all the way up to the house
would be an issue because it's a straight shot
for the fire just to move across onto the house.
And then comes the type of plants that you landscape with.
So succulent plants are typically much safer
to landscape with than wood-bodied plants
like shrubs or trees, right?
Because a succulent's body is filled with water.
So obviously that's gonna be harder to burn
and the fire would sort of dissipate a little bit
when it came in contact with one of these plants.
You could call all of these methods,
and there's some more as well, fire escaping.
What's the best thing you can do for your garden?
The best thing you can do for your garden
is to look at it every day.
What makes a garden successful?
Does the garden make you happy?
And does the garden make the plants happy?
Most plants, when you're planting them,
there is some transition time
where there's a little bit of a freak out there
in a new environment, they've been repotted,
they're not the happiest.
So I would really start to assess things
three weeks to a month later.
Beyond that obvious stuff that's glaring, right,
where the plant shrivels up or it turns a different color
or it starts to droop,
there is another level that you reach
which good gardeners know of
and people that work in greenhouses know of
where it's a sixth sense.
Becoming in tune with your garden and your plants
where you just get a weird feeling about it,
the plant just doesn't feel right to you.
And I can't tell you how many times we've done that.
We've got to unpot this entire tree and look at its roots
and you look and there's mealy all over the roots.
And you're like, there was nothing about this thing
that physically showed that,
it was just, it gave off a sense.
And you should always listen to that intuition.
It's usually correct.
People get really distraught when a plant dies
and I get it,
but I've had tens of thousands of plants die
under my watch, unfortunately.
And most plant people and growers have had the same.
The plant is a being like any other being
and it unfortunately sometimes gets sick
outside of your control or it's too old and it dies
and you just got to take the lessons and then keep moving.
And another point is a lot of plants you buy
will have an instruction on them.
And it tells you,
water approximately every three days
or once a week or something,
and they're living things.
Sometimes you're hungrier, sometimes you're not hungry
and plants are like that also.
Yeah, they're just guidelines.
And so only with experience, only with plants dying,
do you start to hone your sensibility
and your way to pick up on what these plants need
in a very specific, personal way.
Are gnomes cool?
Can I use kitschy stuff
and still be respected by my neighbors?
Yes, gnomes are cool.
You should ask yourself if a gnome is cool.
And if a gnome is cool to you,
then you should put a gnome or many gnomes
or hundreds of gnomes in your garden.
I think the stuff that's cool in reality
is the stuff that people are truly authentically into.
And it's like part of their personality
and they don't give a ----
whether their neighbors respect them or not.
I love a gnome garden, like thousands of gnomes
where some freak has collected them for 30 years
is incredible.
What should I incorporate to attract wildlife?
Food.
What are the plants that this wildlife feeds on?
Plants for pollinators.
If you're looking for butterflies and hummingbirds,
the whole family of aloes have these tubular flowers
that hummingbirds really love.
Milkweed is like sort of the favorite of monarch butterflies.
There's a very common milkweed that comes from tropics
and it's sold everywhere
and should not be confused with the native milkweed
because it makes for Frankenstein butterflies hatching
and with crippled wings and totally screws them up.
Certain palms that have like a lot of like loose thatch
on them or plants that have a sort of wiry material
that birds can take to use to make nests.
Even a small body of water
is a huge attractor for birds.
They keep track of all the water sources in the area.
So even a small bird bath or something
has a huge effect for bringing birds to your backyard.
Okay, next question.
How to landscape on a budget if you are renting?
If the plants are expensive and they're specimen plants,
I wouldn't recommend putting anything in the ground.
If you're gonna landscape in the ground,
you wanna use shrub material.
Whatever you put in there is gonna stay there.
Density always looks rich.
Even if you buy a bunch of cheap five to $10 plants
and you buy a good quantity of them
and you plant them all together,
that itself can look like a really lush, rich garden.
And it's, you know, maybe you spend 300 bucks.
The other thing to consider is container gardening.
If you have like an emotional connection to these plants
and you're gonna care for them
for years and years and years,
maybe it's better that you plant everything in pots
and that so you can take that stuff with you,
full vagabond style.
I had a absolutely pleasurable time
answering all of your questions and happy gardening.
