Cyfrif i lawr i'r crocws...

Blodeuo yn Amgueddfa Genedlaethol Caerdydd.
Y bwlb talaf yn Ysgol Fulwood a Cadley.

Yn ôl ar y 23ain o Ionawr wnes i ddweud y gallai'r blodau Crocws fod ar y ffordd, yna trodd y tywydd oer ac rydym yn dal i aros.

Os bydd y tywydd yn aros rhesymol gynhesu eu dylid blodeuo'r wythnos nesaf. Fel arfer, fel arfer, erbyn hyn bydd rhai ysgolion wedi cael blodau crocws, ond mae ein tywydd y gaeaf rhyfedd wedi arafu twf.

Ar dir yr amgueddfa, mae rhai o fy nghrocws eisoes wedi agor! Tra yn fy ngardd, dwi'n dal i aros ar gyfer blodau, er bod un genhinen Pedr yr wyf blannwyd yn ystod Hydref 2010 wedi trowch ei ben i lawr. Mae hyn yn arwydd sicr ei fod yn barod i flodeuo.

Mae Ysgol Fulwood a Cadley wedi anfon mewn llun o'u bwlb talaf - yn mesur 9.5cm - gweler y llun atodeg.

Byddwch yn amyneddgar a dylai'r blodau crocws agor yn fuan.

Eich Sylwadau:

Stanford in the Vale. Another strange week...Looking at the rainfall for Monday, I think this maybe because of the snow and rain we had over the weekend? We also observed 3mm of snow fall today. We really haven't had any rain for what seem's like in a long time?The bulbs we planted in the ground are slowly coming through, We wonded if this is because we may have planted them to deep? As the pot bulbs look as they are growing much faster? Ans: This is probably the case, if they are planted a too deep they can takke a little longer. They will come though - were they planted in more or less the same spot?

Glyncollen Primary School. Our thermometer broke this week. Can you send us a new one please? Our plants are growing well and we can't wait to take them home. Yr.4 Glyncollen. Ans: Glad your plants are growing well and I've put a thermometer in the post for you.

Woodplumpton Primary School. We have been listening to the weather warnings on the news. It feels really cold outside and yet the temperature has not dropped below freezing. We are surprised! We are learning a lot about temperature and getting really good at guessing what it is. Ans: This is great news glad you are getting really involved in the project. I know what you mean about it feeling really cold some days.

Ysgol Porth Y Felin. The plants have almost sprouted and has been a lot of rain. All of the plants have sprouted some leaves by now and we have seen a mystery bulb. Ans: How exciting not long now!

Earlston Primary School. Snow Monday & Tuesday. Ans: Well done for recording in the snow!

 

Your comments & snow pics

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...

Athro'r Ardd

Mae'r tywydd wedi bod yn oer am y pythefnos diwethaf gyda rhannau o'r DU fod mor oer â finws 11 gradd Celsius! O ganlyniad, nid yw fy bylbiau wedi tyfu unrhyw dalach ers fy lluniau diwethaf. Efallai na fydd fy blodau Crocws yn agor tan canol Chwefror nawr.

Er gwaethaf y tywydd oer, nid ydym wedi cael gormod o rew neu eira yn y DU. Mae hyn oherwydd bod yr aer yn sych iawn ar hyn o bryd - gan fod y gwynt yn chwythu ar draws o Siberia. Llai yn golygu llai o niwed i'n bylbiau - felly peidiwch â phoeni gormod os oes un chi wedi rhoi'r gorau i dyfu. Maent yn pethau bach caled ac maent yr un aros am cyfnod cynnes er mwyn blodeuo.

Gall pethau newid y penwythnos hwn yn ôl yr adroddiad diweddaraf y tywydd yn disgwyl eira! Gweler: http://www.bbc.co.uk/news/uk-16866903

Mae ein hadroddiad tywydd oeraf yn dod o Ysgol Deganwy lle mae'r tymheredd bob amser yn is na sero. Gall fod yn oer yma ond i gymharu ag ardaloedd eraill o Ewrop, rydym yn ffodus iawn. Yn yr Wcráin mae pobol wedi bod yn dioddef yn wael iawn wrth i'r tymheredd gostwng i mor isel â-32C yn y gogledd a'r gorllewin.

Ysgol Porth y Felin yn adrodd bod eu bylbiau yn tyfu'n dda a hyd yn oed eu
bylbiau dirgel wedi dechrau i dyfu. Gadewch i mi wybod os yw eich bylbiau dirgel wedi dechrau i dyfu?

Peidiwch ag anghofio anfon eich cofnodion tywydd wythnosol er mwyn sefyll gyfle i
enillwch daith gweithgaredd natur!

Cadwch yn gynnes. Yr Athro Ardd.
