When can nasturtiums be planted outside?
Similarly, you may ask, how cold can nasturtiums tolerate?
30 to 40 degrees Fahrenheit
Also Know, do nasturtiums come back every year? Although most often grown as annuals, nasturtiums are, botanically, herbaceous perennials; that is, they die to the ground in fall and grow again the next spring. In frost-free areas such as coastal California, they grow like weeds, with 6-inch diameter leaves atop 20-foot-long stems sprawling year-round.
Subsequently, one may also ask, when can nasturtium go outside?
Sowing nasturtiums You can sow seeds thinly outdoors where you want the plants to flower from March to May. Prepare the soil well with added compost or other soil improver and rake to a fine tilth before sowing. Thin out to 15-30cm (6-12in) apart when large enough to handle.
Can you transplant nasturtiums?
Large seeds of nasturtium plants should be sown directly into their permanent location, as nasturtium flowers do not transplant well. You may place a trellis near the planting area of climbing nasturtium varieties and train the colorful vines to climb with little effort.
