When can I plant sweet peas and sunflower seeds?

Sweet pea seed can be sown outdoors from March to early June. In cooler areas sweet peas are often better sown in spring so they will bloom into early summer. And some varieties are recommended for spring sowing in all climates because they are late blooming (summer time). As you may well know sweet peas prefer a sunny position in well-drained soil sheltered from strong winds. Stake or provide support for taller growing varieties . Check with your local Palmers garden centre regarding availability. Sunflower seeds can be planted can be planted right through the year except May, June, July if you are in a warmer temperate part of NZ, and for much cooler areas down south you are best planting in October to December.
