How to Grow Clematis in Containers in the Frozen North P.3
Clematis in containers are apt to need significantly more water. The amount depends on the weather, the size and age of your clematis and the amount of water the soil holds. Check frequently, especially in hot, dry weather. When the top inch or so of soil is dry, it's time to water - and remember to give LOTS!
If you've followed our planting instructions, you won't need to fertilize your clematis again the first year. After that, fertilize in the spring with top quality compost and a couple of doses of rose fertilizer a month or so apart - just like you'd fertilize a clematis planted in the ground!
