Osteospermum

Can you tell me if the African daisy Osteospermum ‘Springstar Aurora’ can be winterized here? It is a healthy plant?

Those South African daisies could never endure a frigid winter here and should be considered annuals. Their daisy-like flowers with blue centers open only in sunlight and bloom best in early summer or later when summer days cool down. They can be seed-grown under lights.

questions

What is the largest tree that one can plant? We are trying to replace some 7- to 8-foot trees that were recently destroyed.

I have two 20-year-old pine trees whose needles are turning brown on the west side of the plants. On the east side I have a compost pile.

I live in the St. Charles region and my soil is mostly clay. What is causing the browning? Should I get rid of the compost? How do I correct the damage?

What does it take to make a climbing hydrangea flower? Ours was planted 3 years ago and is growing energetically. It’s in a protected nook near the patio and gets very little direct sunlight, but doesn’t act sun starved. We gave it a shot of slow release fertilizer on planting, and once since. Somewhat inadvertently it gets plenty of water, since the hose spigot is nearby and leaks, but drainage does not seem to be the problem. It now fully occupies an 8-foot trellis but shows no interest in flowering. Is it youth, lack of sun, too much or too little fertilizer, bugs, lack of pruning or what? When do these plants bloom and what conditions do they like?
