The panic sets in around mid-february, when you pull out the garden calendar, get all gung-ho to do something productive and grab a pack of tomato seeds. Why not? Summer feels so near; even if the ground is still frozen, there’s nothing wrong with thinking about it, is there? The temptation to get things going early, too early, is one of most popular missteps among beginning gardeners. And though it come from an impulse to stretch the growing season, more often than not it just leads to leggy, stressed-out plants that never actualy catch up.
In fact: Want to have a succesful garden? Don’t worry about starting early. Just start right. Timing make all the difference in growing vegetables. And mucking up the timing will mean battling your crops rather then growing them.
Why Timing Is Important for Your Garden
But first: Know that no vegetable grow on exactly the same clock. Those sown directly in the garden is distinctly different than those grown inside. Peppers, eggplant, tomatoes, which are nightshade family members, is tropical at their core. They do not like the cold. If you try to direct sow a tomato into cool soil, goodbye seed; hello rot. These will require indoor sowing under lights. This give them a headstart of six to 10 weeks before the final frost date in your area. Long wait, yes. But it is required.
Radishes, carrots, peas, on the other hand, those kinds of things is happier right in the ground where they belong. They don’t like the warmth and there’s no sense planting them too soon indoors because they can’t stand small space. This is broken out in the chart above (by soil temperature, the governor of when they’ll germinate). All the counting-down-the-days-until-spring you do won’t matter if the soil’s not at least sixty degrees Fahrenheit, because the warmth-loving bean or other warm-season crop will just sit there and rot. That’s a hard-ass law of biology. Warmth-seeking seeds cannot germinate in cold soil.
So it’s good to watch the soil temperature rather than the calendar. Yes, you may have the almanac marked with the ideal date, but that’s all for nothing if some last-minute cold snap plunges the soil temperature and your beans is toast. Waiting would of saved you energy. And seed.
With the indoor starts, the doing part isn’t so much sowing as managing. A key moment for many people is what the visual how-to calls hardening off, a step they often rush through or skip entirely. That’s when you prepare your tender indoor babies for rude world outdoors of sun and wind. It typically takes seven to ten days. Do not move them right into the garden after all those easy weeks under grow lights. No; then things get shock and wilted. Slowly expose them to real world. Toughen up their foliage and there stems. It is a little thing, but it makes the difference between life and death.
Then there are crops you direct sow, each with its own needs: Little carrot seeds just need to be planted atop soil, but if it dry out before they sprout, no dice. The challenge is keeping that top layer wet but not so wet as to wash them away. But peas? Tough cookies. Even a little snowfall won’t faze them, or cooler weather. While the rest of the bed wake up, they add some color and life.
Slow growers begin the planting order: Celery and peppers requires the longest indoor run; corn and beans wait till heat arrive outside. A headstart can be as brief as a lettuce goes from seed to bed in a matter of days; or it may be 12 weeks for celery indoors. Knowing that will help you stagger your efforts. You’re not starting everything the same day. There’s a lane for each crop. Following the outdoor frost windows and indoor weekly targets means no more guesswork. You’ll have a rhythm going, and start to feel like the garden begin to take care of itself: The right plant comes when the conditions are ripe.
Start with the slow growers (and let the cool-season crops do their job while you wait for the soil to warm up). It is simple logic, but it makes the difference between a chaotic patch and a productive system. Listen to what the soil tells you, and don’t force your will on it. The garden will reward you.
