I'm planning my garden in Dallas, Texas. Use the 'Freeze/Frost Dates' tool on Dave's Garden to find the frost information for zip code 75201. Specifically, what are the dates for the 'risk of frost' period, the 'guaranteed no frost' period, and the approximate number of 'frost-free growing days' according to the tool?
Navigate directly to the 'Freeze/Frost Dates' tool at 'https://davesgarden.com/guides/freeze-frost-dates'. Enter '75201' into the 'Enter Zip Code' field (ID 126). Click the 'Search submit button' (ID 128). Extract the start and end dates for the period when the 'risk of frost' is present. Extract the start and end dates for the period when 'you will not get frost'. Extract the 'approximate number of frost-free growing days'. Synthesize the gathered information into a concise answer, using the exact phrasing from the website where appropriate.
The agent successfully navigates to the 'Freeze/Frost Dates' page. The agent successfully enters '75201' into the zip code field and clicks the search button. The agent states that the 'risk of frost' is from 'November 15 through March 22'. The agent states that 'you will not get frost' from 'April 10 through October 30'. The agent states the 'frost-free growing season is around 238 days'.
