Mae’r crocws yn dechrau blodeuo ddiwedd mis Ionawr, felly bydd eich planhigion chi’n blodeuo unrhyw ddiwrnod! Am gyffrous! Cofiwch edrych ar eich planhigion crocws bob dydd i weld os yw’r blodau wedi agor a chofnodi’r dyddiad a thaldra’r planhigyn.

Bydd blodyn y crocws yn borffor gydag anther a stigma oren (y rhannau yng nghanol y petalau). Gallan nhw dyfu i daldra o 10cm.

Peidiwch â phoeni os nad yw’r blodau wedi ymddangos eto! Bydd y tywydd oer a’r eira dros yr wythnosau diwethaf wedi arafu’r broses. Wrth i’r tymheredd gynhesu gall y blodau ymddangos yn sydyn, felly cadwch lygad arnyn nhw!

Diolch yn fawr

Artho'r Ardd

Hiâ Cyfeillion Bylbiau!

Rwy'n amau y bydd llawer o'n potiau o dan eira ar gyfer y dyddiau nesaf! Bydd hyn yn golygu y bydd llawer o ysgolion ar gau. Os ydych yn cael eira rhowch nodyn yn yr adran sylwadau pan fyddwch yn anfon eich cofnodion tywydd.

Dilynwch y ddolen hon i weld yr holl gofnodion tywydd sydd wedi cael eu hanfon i'r graddau. Dewiswch ysgol, yna 'tywydd'.

Dyma rai lluniau o fy egin. Byddwch yn gweld bod y rhai wnes i blannu yn hydref 2011 wedi tyfu llawer mwy na'r rhai wnes i blannu hydref 2012.

Os oes gennych egin yn barod, cymerwch olwg ar fy lluniau i helpu gweithio allan beth yw beth.

Dyma fideo sy'n dangos sut y bydd eich egin yn tyfu.

Eich cwestiynau:

St Mary's Catholic Primary School: We have no records for Monday because it was an inset day. Some of our daffodil bulbs have come through the soil. We have taken photographs and will send them by e-mail. Prof.P: I look forward to seeing them St.Mary’s.

Ladybank Primary School: Thank you for our new thermometer! Prof.P: No worries, thanks for letting me know it arrived safely.

Glyncollen Primary School: Our bulbs have started to grow over the holidays. We hope the frost doesn't get to them. Yr.4. Prof.P: Don’t worry year 4, they are quite tough.

SS Philip and James Primary School:
Happy New Year!  A few daffodil shoots are peeping out of the ground and in one or two pots. Quite a few shoots are emerging in the 'Mystery Bulbs' pot and they are a red/green colour compared to the daffodils shoots which are green. Prof.P: How exciting, not seen my mystery bulb shoots yet.

Greyfriars RC Primary School:
Some are sprouting already! All is good. I am really enjoying this project! Prof.P: glad to hear the bulbs are starting to grow and that you are enjoying.

St Joseph's Primary School (Penarth)
Happy New Year Prof.Plant. We have started to notice a few green shoots in some of our pots and are very excited about the plants beginning to grow. We have talked about the weather forecast for next week and think that we may be sending you photos of snow covered pots! (St. Joseph's Primary School, Penarth.) Prof.P: Yes you were right. Some snow in Cardiff but not enough!

Rhydypenau Primary School:
when we got back to school after the Christmas holidays, our rainfall gauge was full, so we must have had a lot of rain in a fortnight. Prof.P: Yes, we had lots of rain over the holidays – a bit too much! Many people had flooding which must have been awful at Christmas.

Henllys CIW Primary:
Some shoots but no flowers. Prof.P: The flowers will come soon.

Auchtertool Primary School:
When we came back from our Christmas break some of our bulbs were showing growth - not only the ones in pots but also some of those we had planted in the ground! Prof.P: Excellent news!

Ysgol Porth Y Felin:
hello p.p the plants are growing quite quickly but we didn't write down Monday because of teacher training. Prof.P: Thanks for letting me know.

Ysgol Nant Y Coed:
This week the bulbs have started to grow, mostly the mystery bulb. The weather was warm at the beginning and at the end it was cold. Prof.P: Great update, Nant Y Coed.

Tynewater Primary School:
We had 50mm of rainfall on Tuesday because we had been on holiday for two weeks and nobody had emptied the rain gauge. Prof.P: Yes, mine was the same. Thanks for noting the reason.

Blwyddyn Newydd Dda - Gwyddonwyr Gwych! Gobeithio chi wedi cael siawns i ymlacio a nawr yn barod i ymchwilio!

Ar yr adeg hon o'r flwyddyn pethau'n dechrau mynd yn gyffrous iawn. Nawr yw'r amser i wylio eich potiau i weld os oes unrhyw beth yn dechrau tyfu. Mae fy egin cennin Pedr eisoes wedi ymddangos! Danfon llun i mi os mae eginech chi wedi dechrau ymddangos.

Gallai gymryd mis arall neu hyd yn oed chwe wythnos tan fy mlodau yn ymddangos. Mae'r cyfan yn dibynnu ar ein tywydd - os yw'n troi'n wirioneddol oer, yna bydd y twf yn arafu. Os bydd yn aros yn gynnes byddant yn tyfu yn gyflymach.

Y cam nesaf... Defnyddiwch y cyflwyniad PowerPoint i ddarganfod sut i gadw cofnodion blodau. Cofiwch fod yn rhaid i bob un ohonoch roi gwybod i mi pan fydd eich blodau ar agor er mwyn derbyn eich Tystysgrif Gwyddonwyr Gwych.

2012 oedd yr ail flwyddyn wlypaf ar gofnod yn y DU a'r gwlypaf erioed yn Lloegr, y Swyddfa Dywydd gyhoeddi.

Mae'r glaw a oedd yn achosi mwy na 8,000 o gartrefi a busnesau i ddioddef llifogydd arwain at gyfanswm o 1,330.7 mm o law ar gyfer y flwyddyn, dim ond 6.6mm byr o'r flwyddyn y DU gwlypaf a gofnodwyd yn 2000 (1337.3mm).

Dadansoddiad gan y Swyddfa Dywydd yn awgrymu y gall y DU yn mynd yn fwy gwlypach fel newid yn yr hinsawdd yn achosi aer cynhesach i gario mwy o dd?r. Dyddiau o law eithafol - glaw disgwyliedig unwaith bob 100 diwrnod - wedi digwydd bob 70 diwrnod yn 2012. Am ragor o wybodaeth am hyn gweler adroddiad hwn gan y Guardian.

Diolch yn fawr

Hello!

Just in case you don't know - Oriel 1 will be closing on 31 December, so make sure you visit us before then, there's not much time!

The gallery is full of such great objects - my favourites are the good luck charms, the (previously) concealed shoe and the Victorian brooches and jewellery made with woven human hair.

I've pretty much finished my duties for the year! This month we've been busy making Christmas decorations - tissue paper pom poms, paperchains and christmas tree decorations made out of felt - it's been lots of fun.

Next year I'll be starting up two new things - a craft group for adults and a reading group for adults, and we'll also be carrying on with our old favourites - quilt club, craftivism, art cart... it's going to be great!

Wishing you a happy Christmas and wonderful new year!

best wishes, sian.

Ni allaf gredu ei fod ond ddeuddeg cwsg tan Nadolig! Rwyf wedi anfon cerdyn Nadolig atoch chi gyd yn y post. Ddiolch i chi gyd am y gwaith caled rydych wedi ei wneud hyd yn hyn.

Dyma'r chweched wythnos a'r olaf o gofnodi tan Ionawr felli Nadolig Llawen oddi wrth Bwlb bychan a fi.

Rwyf wedi mwynhau'r holl sylwadau a chwestiynau dwi wedi cael yn ystod y flwyddyn hon ac yn edrych ymlaen at ateb mwy yn y Flwyddyn Newydd.

Wyf yn gobeithio bod chi gyd yn cael gwyliau gwych ac yn dychwelyd ym mis Ionawr yn awyddus i weld sut mae eich bylbiau yn ei wneud. Os ydych yn pryderu efallai na fydd eich bylbiau yn ddiogel dros y Nadolig, mynd â nhw adref gyda chi - ond cofiwch fod yn rhaid iddynt gael eu cadw y tu allan!

Mae'r tywydd wedi bod yn oer iawn mewn mannau yn ystod yr wythnos neu ddwy ddiwethaf, ond rhagwelir y bydd yn cael cynhesach. Adroddodd Ysgol Harwell -10 ° c ddydd Iau diwethaf. Oer iawn yn wir! A allwch chi gadarnhau hyn yn gywir?

Fy hoff garol Nadolig yw'r 'Holly and the Ivy' oherwydd ei fod yn cynnwys dau o'n planhigion bytholwyrdd brodorol. Roedd y Celtiaid yn defnyddio planhigion hyn i ddathlu Byrddydd y Gaeaf ac wrth gwrs y maent yn cael eu defnyddio gan Gristnogion i ddathlu'r Nadolig.

Os nad ydych yn gwybod ei fod yma yn y geiriau: http://www.carols.org.uk/the_holly_and_the_ivy.htm

Eich cwestiynau, fy atebion:

Greyfriars RC Primary School: We are really enjoying this! Prof.P: So glad to hear it!

DarranPark Primary: There aren't any signs of growth yet. Prof.P: Give it time; you should see something in January.

GlyncollenPrimary School: We have seen a pattern in our temperatures this week. We have also found out a way to stop our rain gauge from falling over. We hope we don't have any snow next week. From Glyncollen year 4 Prof.P: Great to hear you are seeing patterns in your weather data and that you have found a way to stop your rain gauge from falling over. Please let me know how you do it?

BalcurviePrimary School: We have had a lot of ice this week and freezing temperatures. We also had snow over last weekend and on Thursday. Prof.P: I hope it gets warmer for you at the weekend!

St Joseph's Primary School (Penarth): We have noticed how much colder is has got this week. There has been some ice on our plant pots and we feel really sorry for the poor bulbs! Prof.P: Don’t worry too much I’m sure they will be fine.

KilmaronSpecialSchool: Records for rainfall on days with negative temperatures may not be correct as the water had frozen and expanded so reading may be higher than actual water collected Prof.P: Thanks for letting me know Kilmaron; I will make a note of it. If it happens again melt it before you measure. Thanks

Ysgol Pencae: It rained cats and dogs on Friday and was milder. Did it rain more in Cardiff? Prof.P: We only had 10mms of rain in Cardiff a quarter of what you recorded!
