The snow has gone from around the house, there’s been one decently warm weekend to putter in the yard, and a bed suffering
from snow compaction has been readied for seeds that won’t be planted until the
first week in June. Even then the frost
covers will be ready to throw on if the temperatures look to dip below
freezing. Our growing season is short
in the valley so how do we get things to grow that take more days or growing degree
units in which to mature?
This can be accomplished by using season
extension methods such as starting seeds indoors, green house growing, or lighted
hoop houses over raised garden beds.
This year I am experimenting with starting seeds indoors. It is recommended that you begin seeds inside
6-8 weeks before the last average frost, which is June 15 in Steamboat, right
about end of April beginning of May. I’m
starting cabbage, butternut and acorn squash, broccoli, Brussels sprouts, and
tomatoes. I’ve started some peas too,
although I’ve had good success directly sowing them and may do so to observe
and compare results.
There are a variety of seed
starting supplies available in the stores as well as seed starting potting mix,
which is recommended. The method I used
was to dampen the potting mix in a large tub before putting it fairly densely into
a variety of small 2- 3”pots. I used cleaned
and recycled nursery pots and chose degradable peat pots for the cabbage and
peas to reduce transplanting shock. Plant
2-3 seeds in each pot to insure to get one plant growing in each pot. Plant the seed according to the depth on the seed
package or a rule of thumb is no deeper than four times the size of the
seed.
Water carefully. Begin by simply misting with a spray bottle so as to not disturb the seeds. Do not let the soil dry out, but don’t soak it either as this can inhibit seedling growth. Cover with plastic sheets, the provided clear covers to purchased trays, even glass. Place in a cool location 60-70 degree room, but not in direct sunlight until they have germinated. Gradually move them into bright light.
After the seeds have germinated and
display two true leaves (the leaves above the seed leaves), thin to one plant
per pot by nipping off additional plants at the soil. Maintain the plants’ water needs. Over the course of 7-10 days prior to
transplanting begin the hardening off process by taking the plants outside for
a short to gradually longer period of time daily to expose them to wind/sun and
help reduce transplant shock. Reduce
water as long as the plants are not wilting.
Transplant to the garden, continue water care and frost protection.

applying many things she learned from her 2017 Master Gardener training from
crop rotation, seed starting, and “right plant – right place”. She’s hoping for a prize-winning cabbage this
year.
