This March after the sunshine in February my greenhouse has gone a bit mad with lots of plants flowering early.
Pests have arrived early. This beautiful P. Cordifolium Rubrocinetum was covered in whitefly. I tried washing it with mix of diluted washing up liquid and neam oil to get rid of the fly but it has scorched the leaves with black marks appearing. It turns out I should have used a mild natural soap diluted 1 tsp to a litre of water.
Each variety of geranium tend to have different habits and you get to know them as you go along. There are certain ones like Angel Pelargoniums I find really hard to grow as they attract fly and tend to infect the rest of the greenhouse.
Tips welcome please!
