What's the difference between....

Posted: 25/02/2016 at 20:45

Vermiculite is a hydrous phyllosilicate mineral. It undergoes significant expansion when heated. Exfoliation occurs when the mineral is heated sufficiently, and the effect is routinely produced in commercial furnaces. Vermiculite is formed by weathering or hydrothermal alteration of biotite or phlogopite.

Perlite is an amorphous volcanic glass that has a relatively high water content, typically formed by the hydration of obsidian.

So Vermiculite is a shaped like flat plates and Perlite is little balls.

Both hold water, but in a different way. Perlite soaks it up, but Vermiculite holds it between the plates.

Both are chemically inert so they have no effect on the pH of the compost.

Snowdrops in the green

Galanthus have developed their bulbous form as a food storage organ so they can survive the lack of light from deciduous trees. This means that the bulb itself never dries out and has not developed a skin to protect it from desiccation. So, bulbs which are allowed to become over dried (as in hot G/C's) will have almost certainly died.

Originally it was thought that moving them when growing ie in the green was the best way to getr viable plants without the desiccation problem.

Modern thinking is that the best time to move them is when the bulbs are dormant, but to replant before the bulbs get dry.

I wonder if the bulb companies could find a packaging method to keep the dormant bulbs alive?

Tulips, narcissus etc, developed a bulbous form to avoid the heat of Summer. Their bulbs have a 'coat' to protect them. That is why you may buy their bulbs safely. In fact there are some bulbs which do better if allowed to completely dry out and bake in Summer.

Actually short lived perennials which are grown as biennials. Some of mine are  in their 4th year now. All I do is cut them back when they have finished flowered. It seems to suit them.

Feeding with a high potash feed does help them flower.

How do snowdrops naturally divide?

The straight G. nivalis which we have elsewhere,do set seed. It is only the ones in our wood which appear to be sterile.

The Galanthus in our Wood do not seem to set seed, looked every year for seed, but never found any and the ovaries seem to be empty too. However, they are spread rather expertly by the moles.

We have this one too. Not as good as their original one, but better than any of the other makes of this type.

Professional petrol driven ones are better still, but very expensive and for a normal size garden, not worth the effort.

Viburnum Opulus Cranberry Bush

Fruit - raw or cooked. Juicy but acid, the taste is best after a frost'

The fruits are rich in vitamin C.

They are an excellent substitute for cranberries and are used in preserves, jams etc.

A jam made from the fruit has a very pleasant flavour that goes well in a porridge.

Plant ID please

Has the look of Ragweed, the seeds of which are often included in Bird feeding mixes.

Large quantities of the fruit can cause vomiting and diarrhoea.  The fruit is of very low or zero toxicity, it only causes mild upsets when eaten unripe or in large quantities

And at £44.95 for a small one, Edgeworthia is a bit pricey for us, as well as being too tender.
