Who is Highlanders? I need it
Desert lime has high resistance to hlb and a lot of other things. I want the meyer lemon x desert lime cross. It seems to have the disease resistance of the desert lime for the most part but good tasting lemon like fruit and grows true to seed. It is used as root stock.
Where is this found?
Has CCPP got these? If so, I'm about to place my order. Since I assumed it wasn't in the United States, I didn't even ask them. I tried to place an order, but after tracking (and, I assume, permissions), it costs roughly $50 USD to send out 20 seeds Who knows if they will survive? At that price, I don't think I could risk it.
Seeds or cuttings from who?
The desert lime appears to be unaccessioned in the CCPP which case youd have to request theyll have to reintroduce it again to buy cutttings and that takes literal years lmao.
also there is a link inserted in a period in your post about golf lazers
Do you feel these would be best for grafting or do you think they'd root decently on their own?
Very happy with my order from Frank. Great opportunity to grab some odd ball citrus varieties
I am interested as well.
Yes, I;m interested again. Walt.
My variegated lemon did the EXACT same thing. However, it was a clipping and not a graft. I'm not sure if the variegation causes more weakness and susceptibility to crown rot, etc. I tried treatments using organicide plant doctor and phyton 35 a couple of weeks apart. Anyway, it lost all its leaves and died and I decided to go with a much taller grafted version which has had no problems. Good luck to you!
Has anyone tried growing seeds of Citrus macrophylla ?
I have a lemon rootstock, Citrus macrophylla, that I let grow and now its a pretty tall tree (7-8 ft) and has some large fruits on it. Fruit is still green, size of a large lemon, so I will wait until the fruit turns yellow before I pick them and get the seeds.
I'm planning to grow the seeds and use the seedlings to graft some lemon varieties I have since the seedling rootstock should have stronger roots (tap roots).
Also, has anyone rooted cuttings of the Citrus macrophylla? It may be quicker to grow them from cuttings but I'm not sure how good the root structure will be for use as a rootstock plant.
There is one fungicide which is said to specifically control phytophthera. This is Fosetyl-Aluminium sold as Aliette. See for instance https://www.cropscience.bayer.us/products/fungicides/aliette
As others have said, the best way to guard against the problem is to avoid saturated medium. Make sure water can drain freely through and out of the pot in abround 30 seconds. I also re-plant with the stem raised a little above the surface of the pot mix, even with the highest roots showing.
Root diseases are generally thought to be more prevalent under unfavourable conditions.
Roots in a cold,saturated, wet zone at the bottom of a pot could be alleviated by increasing Air filled porosity and drainage.
Repotting into a taller pots without disturbance may help.
Composted chicken manure ( also a Phosphorous source ) is said to have anti Phytophora properties.
Silica is also seen as a useful addition. Various natural minerals supply Silica, an essential plant nutrient that may be absent from Hydroponics or some pot mixes.
Composted fish fertiliser, with a high crustacean content is said to be useful. Fungi have Chitin based cell walls, as do Arthropods.
Some claim the enzymes in composted crustaceans fertiliser can be anti Fungal.
In Australia composted Eucalypt sawdust is a useful addition to pot mix for root disease suppression, above that of properly composted pine bark.
Other factors that promote root disease are root damage, from incorrect fertiliser application rates, and excessive drying out of the pot mix between waterings.
( drying out increases the fertiliser concentration in the pot mix, more fertiliser in less water ).
