Canni-do nice job, good points, way to own your grow.
The old stock plants suck because they are not on a "growing" seasonal timeline. ONce the plants go dormant from not generating enough new root materials there is something that happens within the vascular system which essentials slows the growth potential. The plant learns to grow slowly because it isn't given space to expand and so the addition of new cells stops. ONce the growing engine has been slowed, there are some inbred varieties which lack natural vigor and don't recalibrate very well. Also the conditions outdoors is not the same as the conditions indoors and if you have lots of old growth without mANY healthy shoots you are going to have a runt.
My wwxBB and WW stock plants are shocked from the transition, while the more vigorous growing skunk types that are not too inbred made better rebounds. I think it has to do with how many time the terminal node has been removed and if the plant can get new fan leaves/leaders to the top of the plant triggering a second explosion of roots.
Also it really depends on the variety again I can sense on whether an old clone will do better then a new clone.
It is the searching new roots which find their way into new places in the soil and then create a strong network that can provide the liquids and nutrients to the top of the plant. If your plant has never been root bound pruning this plant before putting it outside if fine, especially if the roots have freedom and the plant has time to create apex branches at the top of the plant.... before being placed into the outdoors. You are experiencing transplant shock at the same time the plant is needing to regenerate itself.
old orchard wisdom says that maintaining the lead shoot that expands upwards is essential for vigorous growth... so if you have no leaders on a mother to speak of the plant will miss the vernal clues of the season that it must begin to make shoots to catch male pollen. If your plant is stalled in the ground and does not ramp up production quickly once it is the ground it will only be puttering along with a back up engine instead of riding the fan leaves up and outward before it starts its slow reproductive death.
if the plant is shocked for too long it won't achieve rapid growth, and thats the problem... even though there were many shoot the shoots were all stunted and the plant remains in the same shape essentially... plants need to follow the season or else their internal chemistry will not use the sun power to increase energy.
Id say what you are using are some more liked single moms who have a kid but still get laid quickly since they are young...nobody at the club knows about the kids
One more question, I hear all this talk about august stretch and uping the fertilizer we give these plants. How is this done? do we up the dosage or frequency of our nutes?
are any of you fellow tree growers using actinovate or a similar product for a fungus prevention? how do you guys deal with that issue? Ive defoliated for better air circulation and bought some actinovate as a preventative measure...any other good ideas?
