Spring Colour

splash

The Polyanthus A very worthwhile addition to your spring garden. You can either grow your own from seed or buy plants in the autumn. I do the latter. Plant them in the soil in the autumn, water well if the ground is dry. Perhaps feed the soil with some fertiliser ( preferably dig in some well rotted manure every so many years) and then let them get on with it. They are very hardy and during late March they will start flowering. Deadhead to encourage more flowers. By the summer unless you can leave them in the bed dig them up. Put each in their own pot. Split the plants if they have produced secondary plants. Keep in a cold shaded place but do not overwater. You can then use the plants next autumn and repeat until they are old and tired.

Co2 in the atmosphere

Here is a some questions for the climatologists among you.

1) During winter when the trees have no leaves and vegetation is dormant or dead does the percentage of Co2 in the atmosphere rise ? (as plants convert Co2 to Oxygen as part of Photosynthesis )

2) If so does it balance out globally as when the Northern hemisphere is in summertime the Southern is in winter ?

3) Has anyone worked out the percentage of increase in Co2 in the atmosphere related to the loss of vegetation on the planet?

Finally could we plant our way out of trouble and plant loads of vegetation that has a big appetite for Co2 to combat the amount we pump out into the atmosphere ?
