Leave these short-day varieties for southern gardeners and look for long-day varieties such as Alisa Craig or Walla Walla, or day-neutral
onions such as Candy for this region.
: these produce fruits throughout the growing season and will produce some runners.
New Hampshire's strawberry season traditionally lasts only four to six weeks, but researchers working on the multi-state TunnelBerries project were picking day-neutral
strawberries in Durham last November.
Aromas is considered a day-neutral
photoperiod plant with uniform and medium-sized fruits.
(sometimes known as "everbearing") strawberries should be planted in early spring and will produce from July through October.
June-bearing varieties bear one crop in early summer; ever-bearing types produce a crop in early summer and one in fall; and day-neutral
varieties ripen in early summer and continue to produce through fall.
The PAR range was from 0.40-5.40 MJ/[m.sup.2]d and the area which the value was lower than 1.9 MJ/[m.sup.2]d need to plant shade-tolerant species, 1.90-2.90 MJ/[m.sup.2]d is better to plant the day-neutral
species and over 2.90 MJ/[m.sup.2]d is good for the heliophilous species.
A third category that does not react to day length is called day-neutral
. The response to length of daily exposure to light is called photoperiodism.
If space is limited, stick to day-neutral
Strawberry plants may be of two major types (or cultivars), June-bearing or day-neutral
. Most strawberries flower when days are short in spring, producing their bounty of ripe, juicy fruit in June.
Seascape strawberries are day-neutral
, meaning they are not sensitive to the length of available daylight to flower.
Plants can be categorized by their flowering responses as short-day, long-day, or day-neutral
. Some plants flower at the same time of year every year.
