Potatoes, What Comes Next?
I planted a small raised bed of potatoes in the polytunnel which we’ve been enjoying. They took longer to crop than I thought, in part due to the weather, but they’re here now. Just boiled with a little butter, absolutely delicious.
My outdoor potatoes are also doing well, judging by the haulm (the fancy word for the leaves) despite the weather we endured in May. Harvesting the outside first earlies should be starting in the middle of the month which creates some space.
Nature hates a vacuum, so if I don’t plant something to follow, the weeds will fill the gap. If you don’t use the soil, then the weeds will so you may as well keep it productive.
I could just sow a green manure like mustard to feed the soil or I could use the space profitably for some leeks. Another possibility is to sow dwarf French beans.
Even if you sow dwarf beans too late in the year to produce a crop, they provide a good green manure. The roots keep the soil open and being legumes they can provide nitrogen from the roots. As the season ends, the plants provide compost material.
There are articles on green manures on the site here.
