Gardening from first thaw through last frost require forward planning. You must know what blooms when, who wakes up early to do so and who carries the middle of the season to stretch it all into fall. With each glimpse at the pattern, what used to surprise you becomes a choice, a gap in the action.
After winter, it’s all about spring bloomers doing heavy lifting. You know, daffodils and crocuses (see chart, above) open up first, followed closely by tulips and hyacinths. What makes them work as those earliest flowers? Their energy was already stashd in the ground. As they push upward into chilly soil, the rest of the garden’s still weighing options on whether or not to believe that spring is here.
How to Plan Your Garden Year-Round
A couple weeks later come bleeding heart and cherry blossoms filling out the spots beneath trees whose light is still soft. Why does this matter? It provide pollinators with a dependable first meal when there aren’t many other things around ready to go.
Things realy start to heat up by early summer: The chart shows how lavender and dahlias (and so on) overlap with black-eyed Susans, coneflowers and roses. It’s a solid mass of blooms from June to August, the constant deadheading pays off because it tells the plants not to set seed but to keep blooming. You know how it goes.
According to the chart, it’s also time to stagger when you plant sunflowers and zinnias, planting them at different times so they keep going until frost. One giant flush becomes a rolling crop of cuttings and color when you stagger your plantings by a couple weeks’ time.
Fall bloomers are less appreciated then they deserve, but they make a real showing as if to say, “don’t forget us,” as they close out the season. When the annuals begin to fade, sedum and chrysanthemums (along with aster) keeps the border going strong. The grid here makes it obvious how many of them plug in those September-October columns that otherwise would of been empty.
In some slightly shaded locations, toad lilies and Japanese anemones provides much-needed textural interest and height once most summer things is finished. Late nectar sustains bees and migrating butterflies well into first frost.
Another layer of planning comes with bulbs, since they don’t often get planted at the time they will bloom. Bulbs for next springs show go into the ground in fall. Dahlias and other corm types like glads planted in spring wait until about middle of summer. The how-to infographic above helps you line up which bulb goes where on the calendar, and no bulb gets lost in shed and forgotten til it’s too late. One odd exception is colchicums, which seem to emerge out of nowhere from the soil (as if by magic) in fall, long before any foliage even appear.
The entire timeline is anchored by a few decades-long structures: shrubs and trees. The earliest (and latest) bookends to the year? Witch hazel and forsythia. In between come lilacs, the rhododendron, the crape myrtle. Once established, trees and shrubs requires less work each year than perennials do, yet they reward us with consistent color whenever they is scheduled to bloom.
And then there’s the practical payoff: you layer them this way, with one group touching another and never leaving an entire week or more of nothing in between. When planting bulbs, put some at different depths in same hole. Underplant an early shrub with a late perennial. Make space to succession-sow annuals in between.
The end effect is a garden that doesn’t feel patchy but generous instead. The chart above just makes those touches visible before I go digging.
