For a similar substitute to Crystal Apple try Lemon Cucumber
A very prolific variety first introduced from New Zealand in 1934. For best flavor pick at its young stage at about 2” with tender pale greenish skin and mildly sweet flesh. A great little novelty cuke to show off to your friends, plus it compliments a salad well. 25 seeds
Indoors- Individual biodegradable peat/cowpots 1/2” deep, 3-4 weeks before last frost with soil temperature 70 degrees. Transplant after last frost without disturbing the roots
Outdoors- 1/2” deep after last frost in warm soil at least 70 degrees
Harvest- Pick daily to keep the harvest flowing.
Tips- Plant in fertile soil amended with compost. Mulch and keep well watered. Trellising the vines allows for good air circulation and takes less space than hills and provides shade for heat sensitive crops like lettuce.
