  • Leaf gall on a rhodo?

    Updated: 2012-11-30 01:30:06
    I've never seen this behaviour on a rhodo before. Something about it reminds me of leaf galls on azaleas though the leaves in the pictures are not swollen and fleshy. Can anyone identify what's happening here? And should I be worried? John

  • major JM growers (NAmerica)?

    Updated: 2012-11-28 22:43:41
    I noticed that The JM I picked up last week at a nursery in Ontario had a tag from Eshraghi Nursery (Oregon). I guess I was thinking that JM grown for nurseries would be grown closer to home. I would imagine that it is a significant cost to ship a tree so far to their retail location.

  • Question of Legality of Lophophora diffusa in U.S.

    Updated: 2012-11-28 18:37:55
    Is there anybody in the U.S. who owns Lophophora diffusa or any other Lophophora species other than L. williamsii? I obviously know that L. williamsii isn't legal to own in the country, a shame, as it is a fascinating plant. But if any other species in the genus are legal to own, I'd like to have one in my collection. I've looked extensively on the internet to find whether only L. williamsii...

  • Heavy Feeders in the garden

    Updated: 2012-11-28 02:29:35
    We grow a lot of vegetables in the Brassicales family in our garden (broccoli, cabbage, cauliflower, kale). Probably the majority of our garden is in this family which makes it really hard to do crop rotation and make sure they are only in each bed every 4 years. My question is, is there anyway to protect and enhance the beds to stop pest infestation so that we can grow the same family of...

  • Identification: Help with Cactus Identification

    Updated: 2012-11-27 19:21:41
    This cactus belongs to a close friend. She received it as a gift from a neighbor and it seemed perfectly ordinary until mid-November when it developed two spectacular blooms. The blooms appear on short downward stalks. (The bloom "in the pot" broke off and is placed in the pot for the photo.) I would very much like to find one of these! Can anyone identify it? Thanks!

  • Why you prune shade trees in winter

    Updated: 2012-11-19 16:23:44
    The best time to prune most deciduous trees is in winter, this is true for a variety of reasons, it is easier to see the branches when the leaves are gone, the cuts can heal better, there is lower insect and disease levels so there is a lower risk of infection. However the biggest reason [...]

  • Root knot nematodes

    Updated: 2012-11-13 18:14:44
    Nematodes that damage roots in the vege patch, are minute worm-like creatures, also known as eelworms. The female nematodes penetrate plant roots causing lumps to form on the roots, which affect the water-carrying ability of the roots. (These are not to be confused with the nitrogen–fixing lumps that form on the roots of legumes, see [...]
