My soil conditions

Wow, it doesn't look so hot, does it?

Regardless of the pH reading, try to get hold of as much compost as you can and add it. Often lottys have loads of free compost available (ask other lotty members) or local areas have it to either give away or sell. Sandy soil tends to 'eat up' compost quickly so you'll need to add lots yearly. And lots of rotted manure will also help add more tilth and nutrition to the soil. Once your pH tests are back, you can adjust the level if needed, with some horticultural lime.

Mine is just like that, and I suspect Jay's is as well. You just have to work with what you've got 
Apply as much organic matter as you can, as often as you can, and feed all through the year. Sowing green manure over winter to protect the soil from heavy rain, adds a lot of fibre to the soil as well
Seaweed, or calcified seaweed is good for adding minerals which are easily lost from sand.

 

It just shows what's on our minds
