Cold dew: Chrysanthemums are tinged yellow (4 of 5)

April 19th, 2009

Cold dew 14 of 15Inspecting the garden after a week’s absence, I was pleasantly surprised that the passionfruit vine in question has 3 fully formed fruits. Considering the numbers of flowers the vine has, the number of fruits is still proportionately small. I happened to have read a letter in a gardening magazine about this issue. The expert columnist identifed the requirement of cross-polination may be problem for some species. Soil imbalance can also be a factor as the plant needs phosphorous, potassium, boron and zinc to bear fruit. These nutrients and water need to be supplied to a two metre radius around the stem.

    Passionfruit is a hungry plant and needs to be fed. If the leaves are yellowing, the plant needs more iron – iron chelate is the easiest way to add the supplement. The expert from the magazine says that after from determining whether the breed needs help with fertisation (i.e. flowers being self-sterile and needs to be cross-fertised with others), trace elements is the other key thing to look out for. Seaweed fertislier has all of these elements needed for fruiting. Worm tea has many trace elements too – but be aware that proper worm tea is made from soaking worm compost in water for a number of days; the liquid that drains out of the bin is actually leachate – a liquid waste that can contain phytotoxin which can be harmful to plants.
