Strawberries
are a common fruit and are also reliable for home production. It is
easier to manage this type of crop than that of tree fruits, and even a
small garden can yield a good crop of fruit. Even though some strawberry
varieties can be raised from seed, it is more common to buy plants.
When you go to buy plants you want to make sure they are free from
diseases and viruses, so you should purchase them from a reputable
nursery. Registered virus- free plants can yield 50-75 percent more
fruit than ordinary stock plants, and you should not transplant
strawberries out of a old bed because diseases can occur.
Strawberries flourish
on sandy loam soil, but will produce adequately with heavier soils as
long as it is well drained. The bed should be slightly sloped to ensure a
good surface water drainage. Strawberries prefer a slightly acidic
soil, with a pH between 6.0 and 6.5, and should contain adequate organic
matter. Before planting at the beginning of the season, mix the soil
with some garden compost or manure, you can also mix in some green
manure. When you are preparing strawberry plants for planting you should
never allow them to dry out, and to prevent this cover the roots with
moist peat moss and keep them shaded at all times. They will began to
bloom in the spring and can be subjected to frost injury, so you need to
select a site that has good air movement. Try to avoid low- lying areas
that can contain frost pockets and pick slopes that are facing the sun,
because the soil will warm up faster in the spring and induce early
flowering.
The goal during the
first summer of growth after the spring planting is to institute healthy
plants as early in the season as possible. The parent plant will send
out runners in the early summer once it is established, and when this
happens you will need to do frequent shallow cultivation between the
rows, by hand pulling of weeds and mulching 5cm (2in) of straw, hay, or
coarse sawdust in two to three weeks after planting, this will greatly
reduce the number of weeds. You will need a fertilizer that is rich in
potassium, this is added in late summer when the flower buds are started
for the next springs fruit, this will help harden the plants for the
coming winter. The crowns of the plants will need to be protected during
very cold periods in winter, but do not apply mulch too early in the
fall as this can increase crown rot and prevent the plants from going
completely dormant, which will subject them more easily to winter
injury. Some suitable mulches that you can use for winter protection are
coarse sawdust, newspapers, straw, hay, or any loose mulch that will
not compact. Oh and on a final note here, because strawberries are 90
percent water any moisture stress will during growth will reduce yield,
so always ensure adequate watering while cropping.
You can harvest the
fruit when the berries are fully ripe, and a good indicator of this is
any white areas that are noticed means a immature (unripened) berry. If
you allow the berry to reach its full color, it will increase its sugar
content and the size of the berry. When you go to pick the berry do so
with the stem and cap attached, this will keep the berry fresher longer
because when the caps are removed or the berry is injured it will go bad
quickly. You should notice the first harvest around thirty days after
the first bloom, and should be checked every other day for ripe fruit
and any bad fruits should be discarded to prevent diseases from
occurring. When you have picked them, place them in shallow containers
to minimize injury and if not used in the same day you should chill them
promptly.
On a final note, to
avoid diseases do not plant in areas that have had tomatoes, peppers,
potatoes, or eggplant before or in a site that has had strawberries
grown in the last two years. To protect the fruit from birds use a fine
mesh netting.
