Indoor Planting Calendar

Spring has been slow to arrive ….. but we all know it will come and, before too long, summer will follow.

Do you start plants indoors from seed to transplant outside? If you are thinking of starting vegetable seedlings, here are some recommendations for gardeners in our area.

Things you could have started in March

The best time to sow pepper seeds indoors is the beginning of March. Try to keep them as warm as you can during germination by keeping the seed tray by a sunny window.

Seed your tomatoes about 8 weeks before the last frost (around early March).

Sow the seeds about 3 mm deep in a moist seedling mix. You won’t need excess light during germination but as soon as they emerge pour as much light on them as possible.

Things to start in April

Broccoli and Cauliflower
It’s a good idea to start broccoli from seed in early April to make sure it’s ready for harvest before the first hard frosts of fall. Provide lots of light and keep it inside until the last frosts have passed.

Cucumbers are easy to grow indoors and started them in mid April will give a convenient jump start to the season. Plant the seeds about a half inch deep in 3” pots. I recommend only planting 1-2 seeds per pot as they grow quickly.

The seeds prefer a temperature of 20-25 degrees C, but will germinate, albeit grudgingly, with slightly less.

Zucchini & Summer Squash
Starting squash from seed is easy and can be done in late April. Make sure you have a warm spot (above 20 degrees C if possible) and plant 1 or 2 seeds in each 3” pot.

Keep the soil moist and they will germinate in about a week. Give them as much light as possible and they’ll grow quickly. They grow quickly so don’t start them too soon.

Most other vegetable seeds can be seeded directly in the garden when the soil is warm — you can plant them a few weeks before the expected last frost as it will take time for them to germinate. We need a little sun and warm temperatures to warm our soil up this spring!!

Most flower seeds should have been started now if you already haven’t — they take a bit longer to get to a size suitable for spring transplanting.
