Last years Sweet Peas were very disappointing with very few flowers. I have put all the seeds left from last year, Mammoth Mix, into a deep pot of moist compost and my plan is to buy some fresh seeds too for another go this Summer. The Fresh seed is on order and should arrive tomorrow, weather permitting.
The old seeds are showing signs of germination with five green shoots trying to emerge at 6 days. I found a few more Mammoth mixed today, Monday 5th March, and have put them into a deep pot. I want to start a really good amount this year using all my old seeds and some new. New seeds arrived this afternoon so I sowed about twenty of the Spencer Winston Churchill. Winston Churchill is a slightly scented Spencer type that has the most beautiful deep crimson. well ruffled petals. Update 17th March – Both the old and new seeds are up and the first pot have been pinched out above the second leaves. The Spencer variety germinated very quickly and I am already thinking that I may stick to these in future. Easter Sunday 1st April and after soaking them overnight I have sown 25 more of the Spencer Mixed seeds. The original sowings are outside now and about 2′ tall. I have placed an obelisk around them. Fingers crossed for a good year for Sweet Peas.
How To Grow Sweet Peas
- Growing sweet peas is supposed to be easy. Sow into compost in autumn and overwinter or wait until spring and sow in pots or sow into the ground. Before I sow them I soak the seeds in tepid water to rehydrate them. It helps them get off to a quicker start but it isn’t essential as they will still germinate well in moist compost. I usually soak overnight, use a good quality compost and sow several seeds about half an inch deep to a pot. Place in a bright position.
- As the seedlings grow they tend to become tall and leggy. Encourage them to produce side shoots by pinching out the tips. Simply nip off the top of the stem just above a set of leaves. This will make each plant much bushier and more robust. And the more shoots there are the more flowers will be produced.
- Sweet peas climb by twining their tendrils around whatever they touch so help them to cling to the support you have provided.
- Throughout the season you will need to keep them well watered as dry soil will make them go to seed quicker, also deadhead regularly.
- Towards the end of the season leave the seed pods to mature for collection towards next years flowers.
The Sweet Pea is a flowering plant in the genus Lathyrus in the family Fabaceae and is native to Sicily, Cyprus, southern Italy and the Aegean Islands. It is an annual climbing plant growing to a height of 1–2 metres where suitable support is available. A perennial variety is also available but although these plants are stronger the flowers are smaller. However, they do have a place in the garden as do the knee high and basket varieties. I feel the annual Sweet Pea is best for cut flowers and scent.
