Tuber Orders



1. Always pre-prepare your bed, if using

fresh manure leave it to rot over winter.

seperated individual tubers will do better.

 soils - try using a raised bed.

4. Put stake in first, then plant the tuber.

 in height.

6. Keep slug and snail baits laid.

7. Pinch out growing tips after 4 sets of leaves

 appear (stopping).

10. Do not neglect your insect / fungus control programme.

11. Summer watering may be necessary, but preferably in the cool.

12. Remove all spent flowers to prolong flowering season.
