As a horticulture and landscaping expert , I have had the opportunity to mature tomatoes in various regions , including Pennsylvania . When it comes to planting tomatoes in Pennsylvania , the idealistic time can vary depending on the specific condition and climate of the region . However , I can provide some cosmopolitan guideline that can help you determine the best month to engraft tomato in Pennsylvania .
In Pennsylvania , the weather can be quite unpredictable , with frigid temperatures tarry well into spring . Therefore , it is crucial to consider the middling last frost date for your specific area before plant love apple alfresco . The medium last frost day of the month in Pennsylvania typically falls between mid - May and early June . Planting tomatoes before this appointment can put them at endangerment of frost damage , which can stunt their growth or even bolt down them .

Some tomato varieties are more cold - patient of than others and can resist cooler temperature . Determinate varieties , which are shaggy and have a shorter grow season , are in the main more cold - broad and can be found slimly before in the leaping .

However , depending on the salmagundi and personal preference , some gardener may pick out to set out their tomato plant plants indoors from seed as betimes as March or April . It is important to consider the individual characteristics of the tomato miscellanea and supervise local conditions conditions to guarantee successful tomato cultivation in Pennsylvania .
