I planted 3 blue spruce and they grew rapidly — too big for where I put them ,so I want to transplant and am scared to. When ,and how much root ball needs to come out ? Thanks you .

Now (the winter) is a great time. The tree will be dormant and will have the best chance of survival. How big the root ball is depends on how big the tree is however the bigger the better. The less root system you disturb the better. The more roots you rip out and leave behind the more that have to re-grow and remember the root system in place has grown to support the size of the tree as it is now. So if you remove half of the root system you will have half as much root system available to sustain the canopy of the tree. So you will have to cut the tree back and then water, water & water so the roots that are left can absorb as much water as possible to support the canopy. Also using a transplanting fertilizer would help your cause 10-52-10 would be good or something akin to that with a big middle number (phosphorus).

Anita asks: I’m looking for Thailand Giants (Colocasia Gigantea), and Imperial or Illustris Elephant Ears. Do you carry these plants in the summer? Regards, Anita

Hi Anita, We bring in a large tropical plant order in early May. We have ordered Colocasia and Illustris Elephant Ears. If you are interested in these plants, let me know and I will be sure to order some for the store this season. Jeanne@rpgc.ca

Hello, I have an angel trumpet to plant. Can it be planted where a tree was cut down & the stump was ground up? Thank you

Posted on March 12, 2017

Angel’s Trumpet plant can be planted in the area you are speaking of where a tree was taken out and the stump ground out. This is assuming the tree was not a Spruce variety – the needles make the soil very acidic and therefore not a good choice for the Angel’s Trumpet plant. Angel’s Trumpet is a self-seeding plant that likes the sun so please ensure that the area is not overly shaded by other trees. If it likes the area then you may find next year that there are more of them due to the self-seeding nature of the species. Thanks for a great question. Ron Paul Garden Centre
