A rooftop or any cubbyhole-sized garden can be exactly
like the flower or food garden you would love right now on open land, albeit in
miniature, and adapted for life in the sky in a challenging environment. A
vegetable garden will have to be designed with messy birds, rodents,
pollution, etc. in mind.
Beginners will want to go with plants or seedlings
instead of seeds.
Most seed packets have enough seeds to grow a 100-foot
row of plants, which you don't need. And some seeds take a long time to
germinate.
Beware of the squirrel and pigeon. They are not your
friends.
A key mistake that many early gardeners make is picking
the wrong kind of crop for a small space. Root vegetables are really only one
harvest per year, which makes it not a good use of space. Don't immediately go
for tomatoes.... they’re difficult to grow in containers and you can buy
them cheap. Plant more herbs and obscure foods. Think about your
favorite restaurant and take-out meals, and plant what goes into them and your
cooking. Then
cook your home version of that dish.
Avoid gigantic plants like pumpkin, butternut
squash, and watermelon. They’ll grow, but not well, and these plants want to cover the entire ground
quickly.
Opt for smaller fruits and vegetables like tomatoes and chili peppers,
zucchini, eggplant, cucumbers, and
beans. Some, like cucumbers and beans, are climbers. You can stake or trellis your climbers, then grow
ground-covering plants underneath them, like greens or herbs. You get double
the crop in the same amount of space.
If I had access to a flat roof, i'd definitely be growing things
on it, even though my space is not constrained. My large awnings are almost flat, and might be able to take some
weight, but i doubt it can hold up under the weight of wet soil. A bunch of
lightweight pots, and hanging plants, distributed evenly, however, will
probably work. I
would grow a garden inside, or on top of a roof or on a balcony. I had a massive collection of
houseplants growing in my sunny apartment, so what can stop me from growing
herbs and veggies indoors or in teeny places. And always start with a plan.
And permission from the property owner.
Before you head to the
garden center, consider whether you wish to install raised beds or would
rather garden in containers, and approximately how many of each you'd like
to have.
If you're going big with a rooftop
garden, visit this page
Here are some really good
references for your new rooftop gardening experience
Consult with the building engineer. and the building manager to ensure
that the roof or balcony can support the weight of your garden.
Check into access. You'll need easy
access to the roof to transport materials, tools, soil and plants up and
down. And to visit your garden any time you please. That should all be
written.
Check into liability insurance requirements. This
should also be written.
Use sturdy materials. For
containers, opt for large pots that
will be less likely to dry out or blow around in windy conditions. If
installing raised beds, make the beds at least 10-inches deep.
Sometimes the no-brainer escapes me...Find a water source.
Rooftop garden beds and containers will dry out quickly, and may need to be watered daily
during the hottest parts of summer. If at all possible, ask the manager if
you could attach a rain barrel to the roof gutter to collect water, or divert
the flow into a particular area of the garden. If not, a -lugging you will go.
Unless your forward-thinking building manager or landlord has a faucet up
there to hook up a hose. A good idea is to plant drought - and heat-tolerant
plants. They are a lot less fussy, and don't faint dead away in the hot city
environment.
Pick the right soil. In
rooftop containers and raised beds, potting soil is the best medium. it
will hold water better than garden soil, and it's lightweight
and won't compact over time. I wouldn't use regular topsoil or garden
soil. Neither would i add the weight of compost/manure mixtures.
Before beginning the building of you garden, make sure rooftop
gardens are allowed in your area. Your area might have restrictions on
your garden's height, how you use your roof space, and whether certain
decorations are too distracting and not allowable.
If you are renting your house, contact your
landlord to get permission before constructing a rooftop garden.
If you live in a building that is part of a
historical neighborhood, you will need to contact the city
commissioners and local authorities to find out if there are any additional regulations. A vegetable garden wherever you plant it,
will have to be designed with messy and angry birds, rodents, pollution, etc., in mind.
You are responsible for your garden and its mishaps.
Before you become an urban farmer, consider all these
things before laying anything down for a garden.
Good advice for niche gardens that I usually don't take
because i love clay and stone pots....Use plastic plant pots rather than clay
pots. Plants in plastic dry out less quickly because the pots aren’t porous
like clay ones. They're not nearly as heavy when filled with soil. Put a layer
of organic mulch on top of the soil in
the container to reduce water evaporation from the soil.
List
of best vegetables for the urban garden
- based on popularity of the
vegetables and size of the plants
It may sound like blasphemy to read these words.... In the
interest of efficiency and useable space, don't grow anything in limited space
that you can buy cheaply at the farmers market, farm stand, or organic grocery
store. But it really is practical to be practical. The space used for these can
be growing a more expensive and more unique vegetable or herb that you use
frequently. Everyone thinks of the tomato as a perfect thing to grow in the
urban garden. I'd grow cherry tomatoes for my salads, and san marzano plum
tomatoes for sauce. One is to save space, and the other because regular slicing
tomatoes just won't do for my cooking. Think about what you love and eat most,
what isn't readily available or expensive, then go down the list from
there.
Plan
on planting a few flowers to attract more pollinators to your vegetable garden.
No pollination mean no crops.
Cherry Tomatoes - Be sure
to add a trellis for the long vines. Cherry tomatoes are an ideal choice for
container gardens. There are dwarf varieties of cherry tomato that grow as a
shrub. That's my pick. If i need to utilize vertical space, in goes the vining
type behind it..
Bell Pepper - is easily grown in a container with similar
results as one would achieve growing the plant in the ground. Whether in
the ground or in a container, the red or green pepper plant takes about one square foot
of space.
Zucchini
-is a fairly small plant compared to other vines.
Zucchini can be easily grown in a container with similar results as if you grew
it in the ground. The benefits of zucchini are its
small size and versitility. For its relatively small size, zucchini is quite
productive, producing so many fruits per plant. Sometimes too many. So I say
that if your friends or neighbors aren't going to knock on your door bearing
gifts of zucchini they can't get rid of, one zucchini plant is all any sole home
gardener needs, growing inside or outside. As popular as zucchini might be, i'd
prefer to grow cucumbers instead. I use those more than zucchini, i'm likely to
adopt some zucchini, and cucumbers are far better for small places. The
zucchini plants can grow to about 8 feet in diameter, while the cucumbers only
need enough width to allow for the width of the support it's on.
Hot
peppers - Cayenne is small and easy to grow, producing a good-sized crop. Most hot peppers can easily be dried
for spicing up your dishes during the winter.
Beans
- Whether bush or pole beans, the plants don’t take up too much space
and produce an abundance of beans if given the right conditions and placement in
the garden. Bush beans can conserve space in a raised bed, while pole
beans can save space by taking advantage of vertical space. They're as easy to
grow in a tiny space as in the ground in the garden. As a child, I grew bean
plants easily in empty cans on a sunny windowsill.
Salad
greens - all are easy to grow in pots or beds with seeds. I do not like iceburg
or other watery hard-head lettuces. I stick to butterheads, baby spinach and
spring mixes. There are seeds called "mesclun mix". Mesclun is a
combination of seeds that are planted together to create a ready-made young leaf
salad, similar to the packaged salad mixes you can find in grocery stores. The
mixes usually feature leafy greens like arugula, mustard greens, spring greens
and lettuce. I sprinkle the teeny seeds thinly in my large galvanized tub
planters, and plant some more each week until early summer. Heat Kills, so i
plant for a late spring and late fall harvest. I harvest leaves just as soon as
they look ready to star in my salads. I live in Zone 5, a cooler climate, so i
can have lettuces in June and on and off til november in most years. If we have
a cool summer. Water well and
protect from hot temperatures. They will no doubt die in the midsummer heat.
They grow in full sun or partial shade. I opt for partial shade so everybody's
happy.
Kale
is your friend.... Besides being a supergreen known for it's health and dietary benefits,
it's easy to grow.
For a summer harvest, plant seeds in spring two weeks to a month before the
last frost date. Which makes it a favorite crop, because i can get out into
the garden way earlier after our long winters.
Sow seeds in early to midsummer for fall and winter harvest.
Low-maintenance. I like buying seedlings, but if i need to, i use seeds, and
sowing them similar to sowing my lettuces. I like the dwarf varieties, or i keep
the plants small by cutting leaves every day. Baby kale tastes better to me in a
salad than large-leaf varieties. Choose your kale variety according to
your climate and season. Scotch kale, any baby kale, and Siberian kale
are great winter crops that can tolerate frost. Full sun. Provide afternoon
shade in very hot climates.
Radishes - Because i think they're very pretty, and it's an early harvest. I
like them in my salads and in some of my stir fries, and i eat them raw with
salt, pepper and butter. It takes up very little room. The leaves are also edible
and can be substituted for cooked spinach. I think it's more their
attractiveness than need in a garden, in my case.
Mint
- This perennial herb grows so vigorously that it should always be planted
in containers as i mentioned in other articles, because I guarantee that it will
take over your entire garden. But i would be remiss in not suggesting it for the
beginning urban farmer. It needs no care, It's hard to kill. Trust Me. In fact,
i'd even keep it away from my other plants just in case. Such was my experience
with growing it. You can trim by pulling leaves and using them, or allow it to
go to flower and attract lots of bees. I used it for making teas for stomach
upsets, and in preserves and cocktails. It dries beautifully. It grows in full
sun or partial shade.
Chives
In gardens, they’re incredibly easy to grow. This perennial herb has a
long harvest season and will come back year after year if you plant it in good
soil. Harvest chives by simply giving them a haircut with kitchen scissors
when you need it. I have been growing garlic chives.... two herbs, one stone. I
use garlic in just about everything i'd put chives into, so there ya go. It's also
perennial, and returns year after year like scallions. They also have a pretty ornamental grass-like look.
And leaves are hollow, just like regular chives. No fuss at all. They can be
gown on sunny windowsills easily, too. My garlic chives keep bugs away from
nearby plants. They need full sun.
Tip:
I ALWAYS use landscape fabric or black plastic in a pinch, as a weed block, and i
sometimes use gravel, river rock or rubber mulches to keep things cool and
weed-free. For teeny seeds, i wet the soil in a planter, cut a piece of the fabric
and make slits like little rows, lay it on top of the soil. I sprinkle the seeds on or close to the
rows i made. Cut it to size for all your pots and beds. It's permeable, so
it's better than
plastic. Lets the water and air in and keeps the weeds out. There are also rolls or
packages of landscape fabric that already has large holes cut into it with
spacing to lay down and pop
larger plants and flowers into. Pretty neat and worth every penny. I use that
when i can find it to plant entire raised bed gardens with no cutting or
eyeballing involved.
