Start Your Summer Garden Indoors.

Although Colorado weather can be unpredictable this time of year, you can set your sights toward spring by planning for your garden. 

Starting seeds indoors can save money and allow you to select from a wider variety of plants. In general, seeds should be started indoors 4-8 weeks prior to planting. If you search the last frost date for the Longmont area, you’ll find dates ranging from early to mid-May. So find a May date you’re comfortable with and back up from there. 

Seeds can be started in any clean container with adequate drainage. Plant starting trays and peat pots provide a convenient way to start several plants in containers easily suited for transplanting. When selecting soil, formulas designed for house plants work well because they are rich in nutrients and provide excellent drainage. Do not plant seeds too deeply, as this might prevent germination. A household sprayer is the perfect way to water your newly planted seeds as it provides a gentle mist and won’t “flood” the pot. 

After you have planted your seeds and watered, cover them with plastic sheets or glass and keep them in a room-temperature spot, away from direct sunlight until they germinate. Once your plants appear, thin to one plant per pot and gradually move into direct light over a period of 2-3 days. 

Some ideas for plants that can be easily started indoors include; lettuce, peppers, cucumbers and tomatoes. Cold weather vegetables such as broccoli and Brussels sprouts may also be started inside- but act now to have them ready for early season growing. Many varieties of flowers can be started indoors as well. 

We love the CSU Cooperative Extension website for more great information on this subject.
