Organic Growing Tips
Harvest outer leaves regularly to encourage fresh, tender new growth from the centre.
Apply neem oil at the first sign of leaf miner tunnelling to interrupt the pest cycle.
Mulch around plants to suppress weeds and keep slugs away from tender leaf bases.
Chard tolerates more heat than spinach — plant it as a summer substitute when spinach bolts.
