Planning and scheduling your garden project Return to Table of Contents 
While many garden projects can be done, weather permitting, at almost
any time of the year, and some can be done outside of their ideal time
if appropriate measures are taken, some have a more specific timetable.
Here is a rough guide to assist you in planning and scheduling what you
wish to have done.
General Planning and
designing, bed preparation, soil testing, hardscaping, and construction
of arbors and the like can be done at any time of year.
Pruning
The main season for pruning and shaping trees and shrubs is January
through March but can be done any time of year, as needed.
Vegetables Return to Overview
Planning for spring vegetable gardens can commence in December (or
earlier) and is best completed by mid February. Bed preparation should
be done by mid March if possible.
Summer vegetable gardens
can be planned as early as spring ones, with planning best completed by
mid April and bed preparation done by mid-May, although good harvests
of many summer vegetables can be had from late August to near frost in
mid November by getting plants in the ground as late as late June. Even
later can work – I have planted tomatoes in late July and had them
ripen fine fruit in October.
Planning for fall and winter
vegetable gardens is best completed by mid-August, with beds prepared
and plants in the ground in the first week in September. Some
exceptions apply – many root vegetables, such as parsnip, rutabaga,
celeriac, leeks, and some varieties of carrots should go in earlier,
and spinach a little later. In our region, many vegetables will hold
over the winter, available for harvest, with minimal protection, and in
the case of some types of vegetables no protection at all.
If you are planning a four season harvest, planning the seasonal
gardens all at the same time helps assure that space is available for
each crop at the appropriate time.
Spring flowering bulbs
Spring flowering bulbs, such as jonquils, tulips, crocus, and the like
are generally purchased from June through October, although selection
is best when ordered before September. They are delivered in September
and October for planting in October and November, sometimes into
December. Some summer flowering bulbs such as lilies are often fall
planted.
Herb gardens Return to Overview
Depending on the species, the site, and the weather, these are best
planted from mid-March through mid-October, so as to permit them to
become established before extreme heat or cold. As with perennials,
shrubs, vines, and trees, they may need little extra care when summer
planted.
Perennials, shrubs, vines, and trees, including fruit-bearing varieties
These can be planted mid-February through mid-November depending on the
species. Spring and fall are generally the best times, though it can be
done in the heat of the heat of the summer if they get a little extra
coddling.
