The snow didn't last very long in Cardiff but I did manage to get a quick pic of my bulbs. Across the country there has been much more snow. Please send me any pictures you have.

Your questions:

Stanford in the Vale Primary School. What a cold spell we have had, the ground has been rock hard all week! I hope it will not stunt our growth for the bulbs we planted into the ground? Do you think the bulbs we planted into pots should be moved into the greenhouse? Kind Regards. Gardening Club Members.

Ans: Hi Stanford. Great question. Normally, a gardener may put plants into a green house to protect the shoots from the frost, but in this experiment we are recording how the bulbs react to the weather, so please don't put them in the green house as it will affect the final result. Also, these bulbs have evolved to withstand cold winters - so don't worry they should be fine. Prof. P

Woodplumpton Primary School. We have noticed a lot of daffodils flowering but none in our school grounds. Our bulbs are a long way behind other daffodil bulbs we have in our school garden. We wonder if this is because they are older and have flowered many times before. Our mystery bulbs are growing really fast now.

Ans: Hi Woodplumpton. Great observation, I too have noticed that bulbs I planted in previous years have grown a lot more - see my pictures. I agree with what you say, I think the bulbs that were already planted from previous years are taller because they have had more time in the ground to grow. With the mild Autumn and winter they would have began to grow under the ground before we planted this years bulbs on the 20th of October. Hope that makes sence! Prof. P

Fulwood and Cadley. It has been extremely cold this week and the ground is frozen. All our bulbs have shoots now and are growing taller, the tallest being 7cm. Prof. P: Excellent news! my tallest is about that height too!

Ysgol Porth Y Felin. It has been a cold and frosty week.Sorry this is late. It has reached negative numbers in the evening. Prof. P:  Very cold, well done for keeping at the recording in the cold!

Woodplumpton Primary School. We think the mystery bulbs are tulips! Prof.P: Only time will tell...

The weather has been really cold for the last two weeks with parts of theUKbeing as cold as minus 11 degrees Celsius! As a result, my bulbs haven't grown any taller since my last pictures. My Crocus flowers may not arrive until mid Feb now.

Despite the cold weather, we haven't had too much ice or snow in the UK. This is because the air is very dry at the moment - as the wind is blowing across from Siberia. Less ice means less damage to our bulbs - so don't worry too much if yours have stopped growing. They are tough little things and they are just waiting for a warm patch in order to flower.

Things may change this weekend according to the latest weather report that predicts snow! See: http://www.bbc.co.uk/news/uk-16866903

Our coldest weather report comes from Ysgol Deganwy where the temperatures were always below zero. It may be cold here at the moment but compared to other areas ofEurope we are very lucky. In the Ukraine they have suffered very badly as temperatures have fallen to as low as -32C in the north and west.

Ysgol Porth y Felinreport that their bulbs are growing well and even their mystery Bulbs have began to grow. Let me know if your mystery bulbs have begun to grow?

Don't forget to send in your weather records weekly if you can. All weather records need to be sent in to stand a chance to win a nature activity trip!

Keep wrapped up warm. Professor Plant

Crocus:

Watch your crocus very carefully over the next few weeks. They could flower any time, especially if your school is in the South or near the coast. See the reports below from schools that have seen signs that their flowers are on the way.

Since the 6th of January my Crocus has grown 1cm taller. The tiny leaves and buds have pushed through the soil, so I predict that I will have some flowers next week or the one after. See my picture and compare it with your own.

Daffodils:

My Daffodils are 6 cms taller, but I think they could take another 3-5 weeks to flower. 

The daffodils I planted in autumn 2010 have already grown their buds, so it should only be a week or two now before they flower. Look at these pictures so you know what to look for - when yours start to appear.

Answers to your comments:

Westwood CP School - Bulbs are starting to push through - no flowers yet - not too far away. Prof.P: Great news - I can't wait to see the pics!

Ysgol Bro Cinmeirch - Wythnos gwlyb iawn yma! Athro Ardd: Gobeithio bod y bwrw wedi gorffen nawr!

Stanford in the Vale School - Dear Professor plant. What a week! Bitter cold at the start of the week and then considerably warmer towards the end of the week! The children have been hoping for snow :-) Kind regards, Gardening Club. Prof.P: Yes the weather has been very changeable, snow would be lovely but it could harm the flowers!

Woodplumpton Primary School - We are excited that some of our bulbs have started to grow. Now we are looking closely every day and worrying a bit about ones that haven't appeared! Prof.P: Great that some bulbs are coming through, don't worry about the others they should come in their own good time!

Christchurch CP School - Some of the bulbs started to grow. Green shoots have started to come though! Excellent news! Prof.P: Watch them very carefully now.

Laugharne VCP School - We were very excited when we returned to school after the Christmas break to discover that 8 of our daffodils and one of our crocuses have started to grow! We couldn't believe it very early! Prof.P: So exciting! Keep watching to catch those flowering dates.

You may remember our pictures of roses and daisies flowering in December?  Well, top botanist, Dr Tim Rich, who is based at Amgueddfa Cymru - National Museum Wales has looked much further into this strange occurence.

On new year's day he counted how many different types of plants were found to be flowering in the Winter. He found that the warm weather had allowed an amazing 63 wildflowers to bloom, which is much more than the normal average of 20-30 species. See the news reports below that explain the findings of his investigation.

Perhaps you could count the number of wild plants that are in flower around your school? If you do, please send me in some pictures. Meanwhile, I've had many reports from schools telling me that their daffodils and crocus are starting to grow!

Many thanks. Professor Plant.

This year’s bulbs are taking advantage of the mild weather. I can't remember such a warm Christmas holiday, almost every day the temperature was 10 degrees!

Fulwood and Cadley Primary School have sent in some pictures and reported: "We were very excited when we visited our bulbs after the Christmas break. Some of them had grown and we could see small green shoots peeping through the soil."

My plants in Cardiff have begun to grow too, the daffodils are about 3cms tall and the crocus is just shooting through. If you’re not sure which is which please take a look at my pictures. This time last year there was very little sign of growth. 

The bulbs that I planted in autumn 2010 are really coming along now. The daffodils are about 20cms tall. I wonder how early they will flower.

What should schools be doing now? As usual you will need to keep your weather records but now the plants are starting to grow you need to watch them - to see when they flower. Please see Keeping flower records to know what to do. Teachers may find it useful to refer to the Teachers Notes 2011-12 which will point you in the direction of all the useful resources.

Big School's Bird Watch. Don't forget you can help the RSPB to count birds on in your own school grounds between the 16th and 30th of January 2012 http://www.rspb.org.uk/schoolswatch/

Brush-up on your birds by watching our woodland wildcams - which view the woodland birds living at St Fagans: National History Museum.

Many Thanks, Professor Plant.
