Bill Dijk will be familiar to many members, including when he gave his talk about the rare Oncocyclus Iris and subsequent article in NZAGS Bulletin No. 111. He is a horticulturist by training and when he moved to New Zealand he turned his expertise to growing bulbs. Daffodil Acre was the culmination of his efforts and was a staple for almost 40 years. He and wife, Willie, and the whole family were involved in the production of over 400 types of daffodils including some famous daffodil hybrids. On retiring Bill turned his attention to a wider range of bulbs indulging his interest in breeding, particularly tall bearded iris and miniature daffodils. He sourced seed from Oron Peri for example and was the best grower of Oncocyclus from seed, perfecting the technique and growing conditions here in New Zealand. In Tauranga he has many fish boxes of bulbs which are awe inspiring in Spring. For the first time this year NZAGS are fortunate to be able to buy some of his surplus bulbs for our members and as a club fundraiser.

Bill’s Top Bulb Tips: 1. Check how deep the bulbs should be planted – most common spring-flowering bulbs go in about 2.5 times their length, while many South Africa-origin bulbs like their shoulders above ground. However, Bill believes it’s not necessary to be 100% accurate as “nature will correct”. 2. Choose a sunny, well-drained, open situation. If you’re likely to forget where the bulbs are, mark the site, draw a plan, or use bulb baskets. 3. Before planting, dig the ground over and incorporate compost. 4. Never cut off yellowing foliage – it’s feeding next year’s flower. Plant annuals or other, later-flowering bulbs to hide die back. 5. Bulbs in pots are easier to keep track of and, once they’re finished flowering can be moved to hide dying foliage. 6. To keep bulbs flowering well, divide the clump every 3 or 4 years, and keep the site weeded. 7. If you can afford to, repot bulbs every year to keep up flower production. Ensure there is slow-release fertiliser in the new mix, which should be free draining. 8. Bill makes his own planting mix with pumice, compost and sand as the three main ingredients, plus a slow-release fertiliser.
