(1) Buying NEW minis, which come out of the greenhouse
NOT expose new minis to direct sunlight right away as you
may burn the foliage. Keep in the shade for at least a week and then
them 2 to 3 hours of sun a day, for a week to 10 days. After this, you
can then safely put them in full sun.
(Canada and Northern US States)
When you buy a new mini in
a 3 to 4 inch pot, do not plant it into the ground right away!!
small pots are full of new roots, I cut about a 1/4 inch off the bottom
of the root ball with a steak knife.
This way new fine hair roots will develop really fast. I first transplant
mine into one gallon pots. After 3 to 4 months the one gallon pot may
have roots right down to the bottom. If roots go around
in circles it’s time to transplant into 2 gallon pots. Again,
I cut about 1/2 inch off the bottom with a large steak knife. From a
1 gallon pot,
could plant them straight into the ground, but I prefer to leave them
in the 2 gallon pots for the first season.
Years ago I did some experiments
with my own minis and those which I grew initially in pots were 2 to
3 times larger, after one season, than those which
were planted into the ground immediately. Up north the ground never warms
up properly until late May compared to the pots, where the soil warms
up fast with just a few hours of sun per day. In the southern (or hot)
US states, it should be okay to plant right into the ground immediately
Do NOT use chemical
fertilizer for potted roses!!
My friend Tony and I have both killed a number of
minis, growing in one or two gallon pots, using the fertilizer we use
in the rose beds. Too much nitrogen, concentrated because of the small
pots, will damage or kill the roots and the plants may die.
Use slow release
Osmocote or even better, use the organic mix which Tony Denton and I
have been making for ourselves and for members of the Vancouver
Rose Society. You can not over fertilize (kill the roots) with our organic
mix. Tony and I have been using this organic mix for the last 6 to 7
years with outstanding results. The foliage, health and vigour of our
orgaanically fertilized minis
in pots is exceptional as our rose show results prove!
Water soluble fertilizer
can also be used. If it calls for a teaspoon for 4 litres or 1 gall.
of water use a level spoon, but never a
heaped one. As this is also a chemical, rather use a bit less since too
much of this fertilizer may also damage the roots although it may not
kill the plant. Again I am speaking of my
(4) Needless to say, water, water, water!!!
Never lets your pots dry out and note that they have to
be watered more often than roses that are planted in the ground.
