I started sowing sweet pea at the end of February, an old-fashioned highly scented variety which will be allowed to scramble over an arch in the veg garden. I pinched out the growing tips of my young plants a few days ago. Why? I hear you say, well in a nutshell it’s all to do with hormones. Not mine, the sweet pea.
The aim of pinching out sweet pea is to encourage the plants to grow side shoots for more lovely flowers (that’s where the hormone bit comes in) resulting in bushy plants that should flower well all summer, provided they are cut regularly to avoid the plants running to seed.
It’s simple to do, wait until your plants are at least 8 inches tall then pinch off the growing tip between your forefinger and thumb. It certainly works, my sweet pea are sprouting lovely little side shoots already!
