3 simple tips for bigger sweet peas
Left to their own devices sweet pea plants will work their way up their supports, going on to produce masses of colour and scent. However, with a few simple training tricks you can turn an every-day display into a real show-stopper!
My tips here will encourage the fastest growth and the biggest blooms on the longest stems. You can see the difference my training tricks bring about in the photo below.
Sweet Pea ‘Turquoise Lagoon’ in the left hand pot has been left to its own devices, while Sweet Pea ‘Eleanore Udall’ on the right has received some regular attention from me – and what a difference it makes. When I get home this evening I’ll have to add the next tier to the Tower Pot frame, it will be another couple of weeks before I have to do that for ‘Turquoise Lagoon’.
If you want the same results, simply carry out my three easy maintenance tips:
Remove side shoots: Check plants every few days for side shoot development. These divert energy away from the main stem, which delays flowering and reduces eventual flower size. Use snips or your thumb and forefinger to pinch out shoot growth as close to the main stem as possible.
Remove tendrils: Sweet pea plants put a lot of energy into producing tendrils and latching on to available supports. Divert that energy back into the main stem by snipping off tendrils before they latch on to a support.
Tie in: With no tendrils to hold up stems you’ll have to provide an alternative. I use sweet pea rings to keep my stems in place. They are quick and easy to put around both stems and supports, with plenty of room left between them. Therefore, avoiding any stem damage, and the rings can be used again and again. It is so much easier to work with than fiddly twine or raffia.
