Planting Layout
• rows, beds and borders, groups
Site
• location in full sunlight
• well-drained soil
• loosen soil to a depth of
20 to 30 cm
Planting
• mid-May, then again
every two weeks through
mid-June
• croms large and thick,
pointed side up
Care
• layer of mulch such as
straw, grass clippings,or
pine needles to help
keep weeds down and to
preserve a moister
• Temperatures: 10 – 25 C
• in mid summer regularly
watering
Propagation
• Dig up the gladiolus after the
plant's yearly cycle has completed
• Dry the corms to 80% relative
humidity for six to eight days
• Break the cromlets from cromes,
storage them into papper bag
Soil and site
• soil must be well drained,
granular and well supplied
with plant food nutrients
• full sun and partial shade sites
Planting
• The size of bulb, type of soil,
and manner of root growth
are all factors in planting
• in mid-October
• A general rule is to set bulbs
three times their own depth
Propagation
• from bulbs and also from seed
Care
• Keep soil free of weeds
by shallow cultivation
• summer mulch of leaf
mold or peat moss will
keep weeds out,
conserve moisture, and
keep the root cooler
• During summer regularly
watering
• After blooming, plants
need the leaves to
manufacture food
reserves for storage in the
bulb.

Aim of the study was to determine the effect
of planting depth on the time of emergence,
development and flowering of lilium and
gladiolus species.


Experiment was conducted on the 3th of March 2011
Materials: Gladiolus bulbs (smaller and larger)
Lilium bulbs
Planting depth:
 Gladiolus - 5 and 8 cm
 Lilium – 2,6, 5, 7 and 9 cm


We can conclude that the larger the size of
tubers and gladiolus planting depth show a
positive correlation, ie required fewer days
for the entire growth and development of
plants.

Lily bulbs that are planted closer to the soil
surface have shorter development.
