ADJUST DATES TO YOUR TOWN
After you have set your frost date, check it out by looking near the top right of any page in GardenFocused. If it's set correctly then you know we have set all dates to suit your area.
Occasionally your settings can get lost over time although this is unusual. If this happens then simply return to this page, select your country and reset your town.
Below we define "last frost date" as used in this website and the effects it has on your growing conditions.
There is no clear definition of what a "last frost date" is and this explains why dates can differ by a week or two for the same location. Our "last frost dates" are designed to be a practical guide for gardeners. They have been researched to be correct in six out of every seven years. Occasionally a late frost will occur and in several years the last frost date will be slightly earlier.
Other sources may define the "last frost date" as the average date. This means that, on average, in half of the years the last frost will occur after the given date and in the other half of the years the last frost will occur before the given date. We don't believe this is the best estimate for gardeners because in half the years your tender plants, if outside, will be damaged or killed by frost.
Another definition gives the last frost date as the last recorded frost date for a given location over a much longer period, in some cases the last frost date ever recorded. Using this definition will give you a date that is far too late for practical gardening purposes in almost all years.
A final complication is the span of dates given. Our dates refer to a specific week, other sources may refer to a time span of two or three weeks. Other sources may simply refer to a month which is not particularly helpful for gardeners.
MORE ABOUT THE EFFECTS OF FROST IN YOUR GARDEN
At the end of this page we have begun compiling a list of recent weather predictions for the UK in winter, most of which turned out to be a whole pile of sensation seeking rubbish! Read this article to the end and see those predictions. We will add to them in the future.
Weather affects the plants in your garden in many ways. Possibly one of the most obvious is the effect of a late frost on tender plants and vegetables - it can kill them overnight. The more you know about the weather in your area, the better chance you have of raising healthy plants. This article examines how frost forms, where it forms and how the effects can be minimised. Towards the middle of this page is a map of England, Scotland and Wales which attempts to identify the last frost date in your area.
It's easy to confuse the effects of the last frost date and the lowest average temperature on the plants in your garden. In general terms the last frost date will effect when you can plant tender, annual plants and vegetables. The lowest average temperature however will effect which types of non-annual plants you can grow in your garden. For example, if the last frost in your garden is late spring, you will be able to plant out tomato plants a week or so later.
If the same garden has a lowest average temperature of -15°C / 32°F then some shrubs will be killed by that lowest temperature because, although they are frost hardy, they are not fully hardy. An example of such a shrub is Cistus. So it is easily possible that your garden is ideal for growing annual tomatoes but is not suitable for growing shrubs which are only partially frost hardy.
When using the map above be aware that the last frost date can vary quite significantly even in the same town. Factors which can affect the last frost date include slopes and hills, nearby presence of large bodies of water and others. The frost dates associated with each town above are generally accurate in six out of seven years but occasionally a late frost can catch even the experts out. However what is is very clear is that different parts of the UK do have very different last frost dates, a fact which most gardening websites and books simply ignore. This site attempts to address this problem by asking you where you live and then adjusting all dates to match the likely weather conditions in your area.
