Fill a 3
1
/2 in (9 cm) pot with seed-starting
soil. Biodegradable pots, such as those
made from coir fibers, are particularly useful
because they can be planted directly into
the ground, but seedlings will do just as well
when grown in plastic pots.
GROWING
SUNFLOWERS
Bold and often extremely tall, sunflowers are one
of the first flowers that many children recognize.
They are fast-growing and are rewarding to
grow from seed, often flowering into the fall.
YOU WILL NEED

• 3
1
/2 in (9 cm) pots (preferably
biodegradable pots)
• seed-starting soil
• garden compost
• watering can
• plant food

GROWING STRONGER
Tie sunflowers to canes as they
grow to keep them from being
blown over. At a certain size,
they should be self-supporting,
although extra tall varieties may
need a strong support. Water
regularly for best results.

Sunowers
grow very
quickly
from seed

Once the seeds have developed,
keep the plants well watered. If
you have started early, you may
need to pot again into a larger pot
while the plant is still indoors to
keep it growing strongly.
2
Plant one seed per pot,
pushing it just below the
surface. Sow in spring indoors
or in a heated greenhouse.
Seeds can also be planted
directly into the ground in late
spring and early summer, but for
the largest plants, start early.
4
When roots start showing
through the bottom of the pot,
put your seedling into a larger pot or
out into the ground. When all danger
of frost has passed, plant into ground
that has been prepared with plenty
of garden compost.

Few plants are as impressive or as easy to
grow as sunowers. Held on tall stems, the huge
brightly colored owers provide a dazzling
display in late summer.
