We’ve included a free printable pdf too so you can download our advice on when to plant different vegetables. (You’ll find it at the bottom of the post).

Timing is crucial when it comes to vegetable planting and can be the difference between frost damaged plants that will either die or recover slowly and healthy plants providing plentiful crops.

As a beginner gardener it’s really important to understand that all vegetables like different growing conditions and can tolerate different temperatures.

For example, pea plants can usually tolerate temperatures of around -2°C (28°F) whereas runner bean plants aren’t hardy and will die if they are outside in frosty weather.

How do I know when to plant different vegetables?

You’re seed packet will give you an idea of what month you can plant different vegetables however, often they are a little vague.

The problem with monthly growing advice is that real planting out dates vary so much depending on where you live. Even in a small country like Britain, temperatures vary greatly.

What really matters is temperature. The soil needs to be the right temperature for seed germination and the air needs to be the right temperature for your plant to thrive.

Finding the last predicted frost date for your area will give you a better indication of what to plant when in your garden.

A gardener who lives in Aberystwyth in Wales can expect a last predicted frost date of around 1st May whereas a gardener in milder Bristol will only have to wait until 1st March!

With this in mind, we’ve put together a simple printable that will tell you at a glance how close to the last predicted frost you can sow and transplant various vegetables.

Knowing when to sow different vegetables will mean that you’ll loose fewer crops and hopefully your harvests will be better.

Leeks are slow growing so are sown over 2 months before the last frost, transplanted out in May or June and harvested from Autumn through to the following Spring!

Should I plant seeds inside or outside?

There are a 2 main reasons for starting seeds indoors:

1. Because the plant likes warmth.

2. Because we want to give the plant a headstart despite outside conditions not being ideal (pests, temperature).
