Apply a 50/50 mix of All Purpose 4-3-9 and Starter Food 1-3-15 at the start of the season and repeat the application 2 more times at 30 days interval during the season by gently working it in the top 2 inches of soil.
2. Use Fruit and Berry specialized fruit fertilizer as often as possible using a rate of 10-15 ml per litre of water from early spring to early summer and then cut back on frequency. Also use the same solution to spray once every two weeks or so.
This will force the berry plants to build reserve which it will utilize during fruit formation stages and plants will produce a high-quality fruit, rich in flavour, good in size and with extended shelf life. Plants will also continue to produce for a longer period as a result of nutrient reserves.
