1. Remove low growing vigorous growth
David recently bought a Eureka Seedless Lemon and it's been growing beautifully. You can see he has it situated in a warm & sunny protected possie, perfect!
David asks - It is growing very well but I wonder if I should give it a prune in spring ? I have attached a few photos. Should I prune down the very tall branches to encourage low growth?
What David actually needs to do is remove the lower growth that is appearing on the tree.
We want to encourage a strong single straight stem, then the tree can branch up and form a lovely open vase shape.
Removing the lower growth also makes us vigilant and aware of understock growth. This is shoots that sometimes form from the rootstock the tree was grafted onto. Strong and vigorous it can drain energy from your citrus, ensure you always keep lower growth trimmed away from the trunk.
David we would also suggest that in Spring you nip down the taller branches so they are all about even to encourage some branching.
Your tree looks terrific!
2. Leaf Miner are on the munch!
Please take care and inspect the new growth on your citrus, as leaf miner is active in this warm weather....watch us explain how to easily maintain and manage leaf miner here
One of our dear Citrus Men Friends sent in this pic and note explaining the reoccuring issue she's having with leaf miner, on one side of her Citrus Splitzer.
Our advice is to cut it back removing all the damaged growth and then balance up the other side of the plant by cutting it back to the same size. This would require removing the fruit, build vigour in the tree and sacrifice the fruit. This seem harsh however it's best practice for a happy citrus tree.
Keep up the spray of pest oil or neem spray every couple of weeks in the warm months and fertilise.
3. My Citrus Fruit is Dry inside
Citrus trees are very clever....if they are dry and thirsty, which may mean you haven't been watering them adequately, they will draw moisture from the fruit.
So check in with your self first....did they dry out - Was the season especially hot and dry and the tree may have become stressed.
Hungry, stressed trees will not have luscious juicy fruit.
MULCH - WATER - FEED FEED FEED........
Frost can sometimes effect citrus fruit and cause them to dry out and leaving the fruit for a very, very long time on the tree particularly over a hot summer may cause the fruit to dessicate.
4. Why is Grapefruit called Grape fruit?
It's a funny name for such a large fruit....the origin of the name "grapefruit" is not really clear, although two strong theories reign: It is thought that the grapefruit tastes like a grape....which is kind of weird but we are talking from the era of the mid 1600's and who knows how grapes tasted then?
The other suggestion is that the term grapefruit refers to the habit the plant has of producing fruit in clusters rather than individually?
