Vinca minor (Lesser periwinkle) is another one which grows a bit lower. I've seen it growing on a North-facing 45 degree slope underneath Yew trees so it can easily handle low light levels. Both the periwinkles flower on and off all year round and help to stabilise the soil. For a bit of colour in late winter, interplanting with groups of aconitum would look good.
Fingers crossed Allspotz - sounds like it was borers and hopefully now dead ones!
I would plant them in the ground as that means less watering needed and it allows for taller plants. The downside is that after a few years you will need to dig out the area inside the polytunnel where you have been growing things in the ground and replace the soil to replenish it and prevent diseases building up. I do that about every 4 years in my greenhouse which has soil borders.
Yes, suitable for everything and is neutral in pH but contains no nutrients at all.
Good idea to use it in the iron Tetley - we have hard water here so have to buy distilled for that or the iron furs up in no time.
Yes novice7, the water collected by those has been evaporated and condensed, so is effectively distilled water.
It's not a Japanese quince CR - I edited my reply while you were typing your reply.
I think 4 may be a quince if it has spike-like thorns. This is probably the rootstock of a pear tree which was grafted on to it (pears often have 'Quince A' as a rootstock.) As cambridgerose says, the rootstock has been allowed to grow when it sprouted a shoot. If you want to keep the pear, you should cut the quince part off cleanly right where it starts at the bottom.
Planted out a dozen Dierama I grew from seed which have been living in a coldframe for the best part of 3 years so decided it was time to reclaim the space! Next out will be Chaenomeles (also from seed) and Philadelphus cuttings which have been mollycoddled for long enough now.
Yes, once fully compotsted the chippings will become neutral and can then be used anywhere on your garden. To accelerate the composting process, mix in a lot of soft green matter such as grass clippings. You can also add diluted urine or a high-nitrate fertiliser such chicken manure/pellets.
Agree with the above. You also need to remove the slabs around the base of the trees. They all appear to be growing through the gap between slabs and as they grow they will be damaged by the trunk being restricted and then die or be blown down.
