Quick Answer:

Think fertilizing is optional? Think again. Even the laziest greenhouse gardeners will see bigger blooms, healthier seedlings, and more resilient plants with the right fertilizer routine. Whether you’re starting cuttings or transplanting seedlings, container-grown plants need consistent nutrients due to frequent watering and limited soil volume. A simple system—like color-coded watering cans and diluted fertilizer solutions—makes regular feeding easy and effective. By using a light but frequent approach, even busy or forgetful gardeners can ensure robust root growth, reduced transplant shock, and thriving greenhouse plants from season to season.

Truth be told, I can easily ignore a bit of soil spilled on the benches or an occasional unsterilized pot for seedlings. I don't always wear gloves, or fastidiously wash labels. I like the results in my greenhouse. My Sweet Peas bloom early, my tomatoes grow fat on the vine. A little mess, a few germs - my plants and I are no worse for the wear.
